Sensory Activity Quotes

When meditation becomes very deep, breathing becomes slow, steady, and even, and the windows of the senses close to all outward sensations. Next the faculties of the mind quiet down, resting from their usually frantic activity; even the primal emotions of desire, fear, and anger subside. When all these sensory and emotional tides have ceased to flow, then the spirit is free, mukta – at least for the time being. It has entered the state called samadhi. Samadhi

Every authoritarian structure can be visualized as a pyramid with an eye on the top. This is the typical flow-chart of any government, any corporation, any Army, any bureaucracy, any mammalian pack. On each rung, participants bear a burden of nescience in relation to those above them. That is, they must be very, very careful that the natural sensory activities of being conscious organisms — the acts of seeing, hearing, smelling, drawing inferences from perception, etc. — are in accord with the reality-tunnel of those above them. This is absolutely vital; pack status (and “job security”) depends on it. It is much less important — a luxury that can easily be discarded — that these perceptions be in accord with objective fact.

Emotions are not reactions to the world. You are not a passive receiver of sensory input but an active constructor of your emotions. From sensory input and past experience, your brain constructs meaning and prescribes action. If you didn’t have concepts that represent your past experience, all your sensory inputs would just be noise. You wouldn’t know what the sensations are, what caused them, nor how to behave to deal with them. With concepts, your

The neural basis for the self, as I see it, resides with the continuous reactivation of at least two sets of representations. One set concerns representations of key events in an individual's autobiography, on the basis of which a notion of identity can be reconstructed repeatedly, by partial activation in topologically organized sensory maps. ... In brief, the endless reactivation of updated images about our identity (a combination of memories of the past and of the planned future) constitutes a sizable part of the state of self as I understand it. The second set of representations underlying the neural self consists of the primordial representations of an individual's body ... Of necessity, this encompasses background body states and emotional states. The collective representation of the body constitute the basis for a "concept" of self, much as a collection of representations of shape, size, color, texture, and taste can constitute the basis for the concept of orange.

The deep secret of the brain is that not only the spinal cord but the entire central nervous system works this way: internally generated activity is modulated by sensory input. In this view, the difference between being awake and being asleep is merely that the data coming in from the eyes anchors the perception. Asleep vision (dreaming) is perception that is not tied down to anything in the real world; waking perception is something like dreaming with a little more commitment to what´s in front of you. Other examples of unanchored perception are found in prisoners in pitch-park solitary confinement, or in people in sensory deprivation chambers. Both of these situations quickly lead to hallucinations.

Awakening is about introducing a child to sensory experiences, including tastes. It doesn't always require the parent's active involvement. It can come from staring at the sky, smelling dinner as it's being prepared, or playing alone on a blanket. It's a way of sharpening the child's senses and preparing him to distinguish between different experiences. It's the first step toward teaching him to be a cultivated adult who knows how to enjoy himself. Awakening is a kind of training for children in how to profiter - to soak up the pleasure and richness of the moment.

The entire aim and endeavor of yoga is to open up the cocoon of the physical body to the larger sensory body where you experience everything as a part of you. Fasting is an extension of this logic: it is a way of nourishing yourself without any active ingestion. It may be done as a detoxification process nowadays, but this is the internal rationale.

Haekel's reasoning is simple: humans are nature, they are part of, and a result of, evolution. Our actions and our thoughts are products of this evolution. Accordingly, when humans come to know something, ultimately it reveals their own nature. Our knowledge -- which has developed in and is subject to the laws of nature -- is in itself nature (and according to Haeckel, nothing more.) The draftsman, his sensory organs, his motor activity, are results of a development with which, in the end, nature merely represents itself.

evocative cues”—basically any sensory input, like a sight, sound, smell, taste, or touch—can activate a traumatic memory.

The worst thing one can do for a hyperactive child is to put him or her in front of a television set. Television activates the child at the same time that it cuts the child (or adult) off from real sensory stimulation and the opportunity for resolution.

As he analyzed the areas that fire in chronic pain, he observed that many of those areas also process thoughts, sensations, images, memories, movements, emotions, and beliefs—when they are not processing pain. That observation explained why, when we are in pain, we can’t concentrate or think well; why we have sensory problems and often can’t tolerate certain sounds or light; why we can’t move more gracefully; and why we can’t control our emotions very well and become irritable and have emotional outbursts. The areas that regulate these activities have been hijacked to process the pain signal.

Attentional amplification of sensory awareness in any sensory medium is achieved by top-down signals from prefrontal cortex that modulate activity of single neurons in sensory brain areas in the absence of any sensory stimulation and significantly increase baseline activity in the corresponding target region.

Our flesh is like silly putty that distorts when it is ignored. We are constantly obliged to actively participate in its formation, or else it will droop of its own weight and plasticity. This incessant formation we cannot stop. We can only make the choice to let it go its own way - directed by genetics, gravity, appetites, habits, the accidentals of our surroundings, and so on - or the choice to let our sensory awareness penetrate its processes, to be personally present in the midst of those processes with the full measure of our subjective, internal observations and responses, and to some degree direct the course of that formation. We do not have the option of remaining passively unchanged, and to believe for a moment in this illusion is to invite distortions and dysfunctions. Like putty, we are either shaping ourselves or we are drooping; like clay, we either keep ourselves moist and malleable or we are drying and hardening. We must do one or the other; we may not passively avoid the issue.

How can two mutually exclusive behaviors—mating and fighting—be mediated by the same population of neurons? Anderson found that the difference hinges on the intensity of the stimulus applied. Weak sensory stimulation, such as foreplay, activates mating, whereas stronger stimulation, such as danger, activates aggression. In 1952 Meyer Schapiro paid

Over time, unique invisibles, perceivable only because of the sensitivity and openness of the sensory gating in that neural network, are able to be heard and, as well, expressed through the activity of that part of the self. This is what Goethe was talking about when he said that Every new object, clearly seen, opens up a new organ of perception in us.

Gain is a parameter in neural network modeling, which influences the probability that a neuron fires at a given activation level. Single cell recordings in non-human primates have shown that the likelihood of a neuron firing, given a constant sensory input, is enhanced when the stimulus dimension that is preferentially processed by the neuron is attended to.11

Empathy is a sensory experience; that is, it activates the sensory part of your nervous system, including the mirror neurons we’ve talked about. Anger, on the other hand, is a motor action—usually a reaction to some perceived hurt or injury by another person. So by taking people out of anger and shifting them into an empathic behavior, the Empathy Jolt moves them from the motor brain to the sensory brain.

The good painter has to paint two principal things, man and the intention of his mind,” he wrote. “The first is easy and the second is difficult, because the latter has to be represented through gestures and movements of the limbs.”44 He expanded on this concept in a long passage in his notes for his planned treatise on painting: “The movement which is depicted must be appropriate to the mental state of the figure. The motions and postures of figures should display the true mental state of the originator of these motions, in such a way they can mean nothing else. Movements should announce the motions of the mind.”45 Leonardo’s dedication to portraying the outward manifestations of inner emotions would end up driving not only his art but some of his anatomical studies. He needed to know which nerves emanated from the brain and which from the spinal cord, which muscles they activated, and which facial movements were connected to others. He would even try, when dissecting the brain, to figure out the precise location where the connections were made between sensory perceptions, emotions, and motions. By the end of his career, his pursuit of how the brain and nerves turned emotions into motions became almost obsessive. It was enough to make the Mona Lisa smile.

Even so, as an aid to responding quickly, we have reflexes, which means that the central nervous system can intercept a signal and act on it before passing it on to the brain. That’s why if you touch something very undesirable, your hand recoils before your brain knows what’s going on. The spinal cord, in short, is not just a length of impassive cabling carrying messages between the body and the brain but an active and literally decisive part of your sensory apparatus.

Having a ready-to-go list of “droppable” demands can be a lifesaver on high-sensory days or when burnout signs start to surface. Consider employing a traffic light system for your responsibilities, categorizing demands into green, yellow, and red activities. Green tasks can be put aside without notable ramifications. Yellow tasks can occasionally be set aside, depending on prevailing circumstances. Red tasks pose more of a challenge to dismiss, given the potentially significant repercussions.

In other words people who have this gating channel more open can in fact hear things that most of the rest of us cannot. And the more open the channel is, the more they hear. People with very open P50 channels commonly report being “flooded with sound” or hearing “everything at once.” In other words, the unconscious mechanism that filters sound lets more through, so much so that, in some cases, the people exist in a sea of sounds that tend to overwhelm consciousness. This is often complicated by the fact that, commonly, they also have more open N100 channels. N100 (a.k.a. N1) gating channels are those that trigger increased attention and activation of memory. When this channel is also open not only are there more sounds being consciously perceived but conscious attention is directed to each and every one of those sounds. Further, a rapid cross-correlation of new sensory inputs with previous experiences is generated in order to determine subtle meanings and differentiation within them.

And in the seconds to minutes before, those neurons were activated by a thought, a memory, an emotion, or sensory stimuli. And in the hours to days before that behavior occurred, the hormones in your circulation shaped those thoughts, memories, and emotions and altered how sensitive your brain was to particular environmental stimuli. And in the preceding months to years, experience and environment changed how those neurons function, causing some to sprout new connections and become more excitable, and causing the opposite in others.

Unfortunately, most researchers studying gating dynamics in children are, as with “schizophrenia,” focused on “normal” versus “abnormal” gating. And all children are expected to fit into the defined “normal” range of behavior. Sensory gating dynamics outside that culturally determined “norm” are defined as abnormal and researchers note that Individuals with these characteristics have been classified as having sensory processing deficits (SPD). Such behaviors disrupt an individual’s ability to achieve and maintain an optimal range of performance necessary to adapt to challenges in life. The manifestations of SPD may include distraction, impulsiveness, abnormal activity level, disorganization, anxiety, and emotional lability that produce deficient social participation, insufficient self-regulation and inadequate perceived competence.1 Those terms, if you look at them more closely, are exterior, “authority” generated terms; they relate directly to the paradigm in place in those authorities. They really don’t have much to say about the interior experience of the children so labeled.

Scientists think rationalists are mad because the rationalists are dancing to the Music of the Spheres, to which scientists are stone deaf. Scientists are like the blind describing the visible world to the sighted. The vast majority of reality is hidden from the human senses, yet scientists have chosen to consider the observable as the only reality, and everything else as unreal. In fact, the unobservable is true reality, and the observable is a sensory phenomenal, empirical delusion that actively masks non-sensory, noumenal, rational reality.

Different mechanisms underlie short- and long-term memory storage. A single sensory neuron from the siphon skin connects to a motor neuron that innervates the gill. Short-term memory is produced by a single shock to the tail. This activates modulatory neurons (in blue) that cause a functional strengthening of the connections between the sensory and motor neurons. Long-term memory is produced by five repeated shocks to the tail. This activates the modulatory neurons more strongly and leads to the activation of CREB-1 genes and the growth of new synapses.

When repeated shocks and repeated release of serotonin are paired with the firing of the sensory neuron in associative learning, a signal is sent to the nucleus of the sensory neuron. This signal activates a gene, CREB-1, which leads to the growth of new connections between the sensory and motor neuron (fig. 4.5, right) (Bailey and Chen 1983; Kandel 2001). These connections are what enable a memory to persist. So if you remember anything of what you have read here, it will be because your brain is slightly different than it was before you started to read.

He refers to the Imagination as an organ of perception. Without it, all the phenomena of religious experience are impossible. It is the means by which we perceive symbols. The Active Imagination guides, anticipates, molds sensory perception; that is why it transmutes sensory data into symbols. The Burning Bush is only a brushwood fire if it is merely perceived by the sensory organs. In order that Moses may perceive the Burning Bush and hear the Voice calling him “from the right side of the valley”—in short, in order that there may be a theophany—an organ of trans-sensory perception is needed.22

in adults the anterior cingulate cortex activates when they see someone hurt. Ditto for the amygdala and insula, especially in instances of intentional harm—there is anger and disgust. PFC regions including the (emotional) vmPFC are on board. Observing physical pain (e.g., a finger being poked with a needle) produces a concrete, vicarious pattern: there is activation of the periaqueductal gray (PAG), a region central to your own pain perception, in parts of the sensory cortex receiving sensation from your own fingers, and in motor neurons that command your own fingers to move.fn3 You clench your fingers.

It is possible, just as it is with the auditory training of musicians, to begin using the feeling sense actively. This will increase neuronal development in the hippocampal and the cardiovascular (heart) system and with practice, over time, increase sensitivity to tiny modulations in that sensory flow. Sensitivity to the tiniest shifts in feeling will develop, just as they do in musicians with sound complexes. And, with experience, the ability to determine the meanings inside those feelings will become a reliable skill. In other words, it becomes possible to immediately know the intent of the dog as soon as it is seen/nonkinesthetically felt.

Nerve signals are not particularly swift. Light travels at 300 million meters per second, while nerve signals move at a decidedly more stately 120 meters a second—about 2.5 million times slower. Still, 120 meters a second is nearly 270 miles an hour, quite fast enough over the space of a human frame to be effectively instantaneous in most circumstances. Even so, as an aid to responding quickly, we have reflexes, which means that the central nervous system can intercept a signal and act on it before passing it on to the brain. That’s why if you touch something very undesirable, your hand recoils before your brain knows what’s going on. The spinal cord, in short, is not just a length of impassive cabling carrying messages between the body and the brain but an active and literally decisive part of your sensory apparatus.

A clearer picture of what is happening in the brain during non-REM sleep,14 during sleepwalking,15 and during confused arousals16 has been achieved through neuroimaging and EEG. It appears that the brain is half awake and half asleep: the cerebellum and brainstem are active, while the cerebrum and cerebral cortex have minimal activity. The pathways involved with control of complex motor behavior and emotion generation are buzzing, while those pathways projecting to the frontal lobe, involved in planning, attention, judgment, emotional face recognition, and emotional regulation are zoned out. Sleepwalkers don’t remember their escapades, nor can they be awakened by noise or shouts, because the parts of the cortex that contribute to sensory processing and the formation of new memories are snoozing, temporarily turned off, disconnected, and not contributing any input to the flow of consciousness.

So, let’s reorient from exterior to interior. “Distraction” then becomes boredom; “impulsiveness” becomes self-generated explorative behavior based on what captures interest; “abnormal activity level” is thus high-energy levels generating multiple task interests; “disorganization” is failure to follow rigid organizational regimens set by others; “anxiety”—well, we all know that one: what the hell kind of world did I get born into?; “emotional lability” is, in fact, a wide range of emotions that are accessed when adults or the exterior culture don’t want them to be. In other words, should you have ever read Mark Twain, what is being described is “Tom Sawyer syndrome,” a once common state of being in many if not most children. The more widely open the sensory gating channels are, the more the child’s behavior alters from what is currently held to be the cultural norm in the West. On average, some

The auditory cortex seems to perform a simple calculation: it uses the recent past to predict the future. As soon as a note or a group of notes repeats, this region concludes that it will continue to do so in the future. This is useful because it keeps us from paying too much attention to boring, predictable signals. Any sound that repeats is squashed at the input side, because its incoming activity is canceled by an accurate prediction. As long as the input sensory signal matches the prediction that the brain generates, the difference is zero, and no error signal gets propagated to higher-level brain regions. Subtracting the prediction shuts down the incoming inputs—but only as long as they are predictable. Any sound that violates our brain’s expectations, on the contrary, is amplified. Thus, the simple circuit of the auditory cortex acts as a filter: it transmits to the higher levels of the cortex only the surprising and unpredictable information which it cannot explain by itself.

in adults the anterior cingulate cortex activates when they see someone hurt. Ditto for the amygdala and insula, especially in instances of intentional harm—there is anger and disgust. PFC regions including the (emotional) vmPFC are on board. Observing physical pain (e.g., a finger being poked with a needle) produces a concrete, vicarious pattern: there is activation of the periaqueductal gray (PAG), a region central to your own pain perception, in parts of the sensory cortex receiving sensation from your own fingers, and in motor neurons that command your own fingers to move.fn3 You clench your fingers. Work by Jean Decety of the University of Chicago shows that when seven-year-olds watch someone in pain, activation is greatest in the more concrete regions—the PAG and the sensory and motor cortices—with PAG activity coupled to the minimal vmPFC activation there is. In older kids the vmPFC is coupled to increasingly activated limbic structures.13 And by adolescence the stronger vmPFC activation is coupled to ToM regions. What’s happening? Empathy is shifting from the concrete world of “Her finger must hurt, I’m suddenly conscious of my own finger” to ToM-ish focusing on the pokee’s emotions and experience.

More Activities to Develop Sensory-Motor Skills Sensory processing is the foundation for fine-motor skills, motor planning, and bilateral coordination. All these skills improve as the child tries the following activities that integrate the sensations. FINE-MOTOR SKILLS Flour Sifting—Spread newspaper on the kitchen floor and provide flour, scoop, and sifter. (A turn handle is easier to manipulate than a squeeze handle, but both develop fine-motor muscles in the hands.) Let the child scoop and sift. Stringing and Lacing—Provide shoelaces, lengths of yarn on plastic needles, or pipe cleaners, and buttons, macaroni, cereal “Os,” beads, spools, paper clips, and jingle bells. Making bracelets and necklaces develops eye-hand coordination, tactile discrimination, and bilateral coordination. Egg Carton Collections—The child may enjoy sorting shells, pinecones, pebbles, nuts, beans, beads, buttons, bottle caps, and other found objects and organizing them in the individual egg compartments. Household Tools—Picking up cereal pieces with tweezers; stretching rubber bands over a box to make a “guitar”; hanging napkins, doll clothes, and paper towels with clothespins; and smashing egg cartons with a mallet are activities that strengthen many skills.

My general philosophy regarding endurance contains four key points: 1. Build a great aerobic base. This essential physical and metabolic foundation helps accomplish several important tasks: it prevents injury and maintains a balanced physical body; it increases fat burning for improved stamina, weight loss, and sustained energy; and it improves overall health in the immune and hormonal systems, the intestines and liver, and throughout the body. 2. Eat well. Specific foods influence the developing aerobic system, especially the foods consumed in the course of a typical day. Overall, diet can significantly influence your body’s physical, chemical, and mental state of fitness and health. 3. Reduce stress. Training and competition, combined with other lifestyle factors, can be stressful and adversely affect performance, cause injuries, and even lead to poor nutrition because they can disrupt the normal digestion and absorption of nutrients. 4. Improve brain function. The brain and entire nervous system control virtually all athletic activity, and a healthier brain produces a better athlete. Improved brain function occurs from eating well, controlling stress, and through sensory stimulation, which includes proper training and optimal breathing.

When General Genius built the first mentar [Artificial Intelligence] mind in the last half of the twenty-first century, it based its design on the only proven conscious material then known, namely, our brains. Specifically, the complex structure of our synaptic network. Scientists substituted an electrochemical substrate for our slower, messier biological one. Our brains are an evolutionary hodgepodge of newer structures built on top of more ancient ones, a jury-rigged system that has gotten us this far, despite its inefficiency, but was crying out for a top-to-bottom overhaul. Or so the General genius engineers presumed. One of their chief goals was to make minds as portable as possible, to be easily transferred, stored, and active in multiple media: electronic, chemical, photonic, you name it. Thus there didn't seem to be a need for a mentar body, only for interchangeable containers. They designed the mentar mind to be as fungible as a bank transfer. And so they eliminated our most ancient brain structures for regulating metabolic functions, and they adapted our sensory/motor networks to the control of peripherals. As it turns out, intelligence is not limited to neural networks, Merrill. Indeed, half of human intelligence resides in our bodies outside our skulls. This was intelligence the mentars never inherited from us. ... The genius of the irrational... ... We gave them only rational functions -- the ability to think and feel, but no irrational functions... Have you ever been in a tight situation where you relied on your 'gut instinct'? This is the body's intelligence, not the mind's. Every living cell possesses it. The mentar substrate has no indomitable will to survive, but ours does. Likewise, mentars have no 'fire in the belly,' but we do. They don't experience pure avarice or greed or pride. They're not very curious, or playful, or proud. They lack a sense of wonder and spirit of adventure. They have little initiative. Granted, their cognition is miraculous, but their personalities are rather pedantic. But probably their chief shortcoming is the lack of intuition. Of all the irrational faculties, intuition in the most powerful. Some say intuition transcends space-time. Have you ever heard of a mentar having a lucky hunch? They can bring incredible amounts of cognitive and computational power to bear on a seemingly intractable problem, only to see a dumb human with a lucky hunch walk away with the prize every time. Then there's luck itself. Some people have it, most don't, and no mentar does. So this makes them want our bodies... Our bodies, ape bodies, dog bodies, jellyfish bodies. They've tried them all. Every cell knows some neat tricks or survival, but the problem with cellular knowledge is that it's not at all fungible; nor are our memories. We're pretty much trapped in our containers.

We will not find the enemy.8 Because the enemy does not exist in space, but in time: four thousand years ago. We are about to destroy each other, and the world, because of profound mistakes made in Bronze Age patriarchal ontology—mistakes about the nature of being, about the nature of human being in the world. Evolution itself is a time-process, seemingly a relentlessly linear unfolding. But biology also dreams, and in its dreams and waking visions it outleaps time, as well as space. It experiences prevision, clairvoyance, telepathy, synchronicity. Thus we have what has been called a magical capacity built into our genes. It is built into the physical universe. Synchronicity is a quantum phenomenon. The tachyon is consciousness, which can move faster than light. So, built into our biological-physical selves evolving linearly through time and space, is an authentically magical capacity to move spirally, synchronously, multi-sensorially, simultaneously back and forth, up and down, in and out through all time and space. In our DNA is a genetic memory going back through time to the first cell, and beyond; back through space to the big bang (the cosmic egg), and before that. To evolve then—to save ourselves from species extinction—we can activate our genetic capacity for magic. We can go back in time to our prepatriarchal consciousness of human oneness with the earth. This memory is in our genes, we have lived it, it is ours. This

The motor activities we take for granted—getting out of a chair and walking across a room, picking up a cup and drinking coffee,and so on—require integration of all the muscles and sensory organs working smoothly together to produce coordinated movements that we don't even have to think about. No one has ever explained how the simple code of impulses can do all that. Even more troublesome are the higher processes, such as sight—in which somehow we interpret a constantly changing scene made of innumerable bits of visual data—or the speech patterns, symbol recognition, and grammar of our languages.Heading the list of riddles is the "mind-brain problem" of consciousness, with its recognition, "I am real; I think; I am something special." Then there are abstract thought, memory, personality,creativity, and dreams. The story goes that Otto Loewi had wrestled with the problem of the synapse for a long time without result, when one night he had a dream in which the entire frog-heart experiment was revealed to him. When he awoke, he knew he'd had the dream, but he'd forgotten the details. The next night he had the same dream. This time he remembered the procedure, went to his lab in the morning, did the experiment, and solved the problem. The inspiration that seemed to banish neural electricity forever can't be explained by the theory it supported! How do you convert simple digital messages into these complex phenomena? Latter-day mechanists have simply postulated brain circuitry so intricate that we will probably never figure it out, but some scientists have said there must be other factors.

Interactions with the world program our physiological and psychological development. Emotional contact is as important as physical contact. The two are quite analogous, as we recognize when we speak of the emotional experience of feeling touched. Our sensory organs and brains provide the interface through which relationships shape our evolution from infancy to adulthood. Social-emotional interactions decisively influence the development of the human brain. From the moment of birth, they regulate the tone, activity and development of the psychoneuroimmunoendocrine (PNI) super-system. Our characteristic modes of handling psychic and physical stress are set in our earliest years. Neuroscientists at Harvard University studied the cortisol levels of orphans who were raised in the dreadfully neglected child-care institutions established in Romania during the Ceausescu regime. In these facilities the caregiver/child ratio was one to twenty. Except for the rudiments of care, the children were seldom physically picked up or touched. They displayed the self-hugging motions and depressed demeanour typical of abandoned young, human or primate. On saliva tests, their cortisol levels were abnormal, indicating that their hypothalamic-pituitary-adrenal axes were already impaired. As we have seen, disruptions of the HPA axis have been noted in autoimmune disease, cancer and other conditions. It is intuitively easy to understand why abuse, trauma or extreme neglect in childhood would have negative consequences. But why do many people develop stress-related illness without having been abused or traumatized? These persons suffer not because something negative was inflicted on them but because something positive was withheld.

Let’s explore some key signs you should be watchful for: Unrelenting fatigue: Persistent exhaustion, even after adequate rest and sleep, is a key part of Autistic burnout. When grappling with burnout, your body may feel utterly exhausted, leaving you scrambling for energy to complete even the simplest tasks. Heightened sensory sensitivities: Sensitivity to sensory stimuli—be it noise, light, texture, or smell—intensifies during burnout, amplifying your susceptibility to sensory overload, meltdowns, and shutdowns. Sensory stimuli that used to feel manageable may now feel overwhelming. Skills and functioning decline: A conspicuous drop in skills like focusing, organizing, problem-solving, and speaking is another feature of burnout and makes social interactions more daunting. Emotional dysregulation: Burnout-induced dysregulation in your nervous and sensory systems hampers your ability to manage your emotions, resulting in intense emotions or emotional numbness. Increased anxiety, irritability, or feelings of being overwhelmed are common during burnout. Diminished tolerance for change: During burnout, your capacity to absorb and adapt to change wanes, and you may seek comfort in sameness and predictability. You might experience heightened distress in the face of the unexpected. Social isolation: Burnout can spark a retreat into solitude and diminish your ability to engage socially. You might withdraw from social interactions and lose motivation for once-enjoyed hobbies or activities. Masking: Burnout can throw a wrench in your masking abilities, and it can be confusing if you don’t understand what is happening! Interestingly, lots of adults don’t get their autism diagnosis until they are in burnout and have lost their ability to mask.

In order to avoid the deafening of conspecifics, some bats employ a jamming avoidance response, rapidly shifting frequencies or flying silent when foraging near conspecifics. Because jamming is a problem facing any active emission sensory system, it is perhaps not surprising (though no less amazing) that similar jamming avoidance responses are deployed by weakly electric fish. The speed of sound is so fast in water that it makes it difficult for echolocating whales to exploit similar Doppler effects. However, the fact that acoustic emissions propagate much farther and faster in the water medium means that there is less attenuation of ultrasound in water, and thus that echolocation can be used for broader-scale 'visual' sweeping of the undersea environment. These constraints and trade-offs must be resolved by all acoustic ISMs, on Earth and beyond. There are equally universal anatomical and metabolic constraints on the evolvability of echolocation that explain why it is 'harder' to evolve than vision. First, as noted earlier, a powerful sound-production capacity, such as the lungs of tetrapods, is required to produce high-frequency emissions capable of supporting high-resolution acoustic imaging. Second, the costs of echolocation are high, which may limit acoustic imaging to organisms with high-metabolisms, such as mammals and birds. The metabolic rates of bats during echolocation, for instance, are up to five times greater than they are at rest. These costs have been offset in bats through the evolutionarily ingenious coupling of sound emission to wing-beat cycle, which functions as a single unit of biomechanical and metabolic efficiency. Sound emission is coupled with the upstroke phase of the wing-beat cycle, coinciding with contraction of abdominal muscles and pressure on the diaphragm. This significantly reduces the price of high-intensity pulse emission, making it nearly costless. It is also why, as any careful crepuscular observer may have noticed, bats spend hardly any time gliding (which is otherwise a more efficient means of flight).

While the visual areas of the brain are active, other areas involved with smell, taste, and touch are largely shut down. Almost all the images and sensations processed by the body are self-generated, originating from the electromagnetic vibrations from our brain stem, not from external stimuli. The body is largely isolated from the outside world. Also, when we dream, we are more or less paralyzed. (Perhaps this paralysis is to prevent us from physically acting out our dreams, which could be disastrous. About 6 percent of people suffer from “sleep paralysis” disorder, in which they wake up from a dream still paralyzed. Often these individuals wake up frightened and believing that there are creatures pinning down their chest, arms, and legs. There are paintings from the Victorian era of women waking up with a terrifying goblin sitting on their chest glaring down at them. Some psychologists believe that sleep paralysis could explain the origin of the alien abduction syndrome.) The hippocampus is active when we dream, suggesting that dreams draw upon our storehouse of memories. The amygdala and anterior cingulate are also active, meaning that dreams can be highly emotional, often involving fear. But more revealing are the areas of the brain that are shut down, including the dorsolateral prefrontal cortex (which is the command center of the brain), the orbitofrontal cortex (which can act like a censor or fact-checker), and the temporoparietal region (which processes sensory motor signals and spatial awareness). When the dorsolateral prefrontal cortex is shut down, we can’t count on the rational, planning center of the brain. Instead, we drift aimlessly in our dreams, with the visual center giving us images without rational control. The orbitofrontal cortex, or the fact-checker, is also inactive. Hence dreams are allowed to blissfully evolve without any constraints from the laws of physics or common sense. And the temporoparietal lobe, which helps coordinate our sense of where we are located using signals from our eyes and inner ear, is also shut down, which may explain our out-of-body experiences while we dream. As we have emphasized, human consciousness mainly represents the brain constantly creating models of the outside world and simulating them into the future. If so, then dreams represent an alternate way in which the future is simulated, one in which the laws of nature and social interactions are temporarily suspended

For millennia, sages have proclaimed how outer beauty reflects inner goodness. While we may no longer openly claim that, beauty-is-good still holds sway unconsciously; attractive people are judged to be more honest, intelligent, and competent; are more likely to be elected or hired, and with higher salaries; are less likely to be convicted of crimes, then getting shorter sentences. Jeez, can’t the brain distinguish beauty from goodness? Not especially. In three different studies, subjects in brain scanners alternated between rating the beauty of something (e.g., faces) or the goodness of some behavior. Both types of assessments activated the same region (the orbitofrontal cortex, or OFC); the more beautiful or good, the more OFC activation (and the less insula activation). It’s as if irrelevant emotions about beauty gum up cerebral contemplation of the scales of justice. Which was shown in another study—moral judgments were no longer colored by aesthetics after temporary inhibition of a part of the PFC that funnels information about emotions into the frontal cortex.[*] “Interesting,” the subject is told. “Last week, you sent that other person to prison for life. But just now, when looking at this other person who had done the same thing, you voted for them for Congress—how come?” And the answer isn’t “Murder is definitely bad, but OMG, those eyes are like deep, limpid pools.” Where did the intent behind the decision come from? The fact that the brain hasn’t had enough time yet to evolve separate circuits for evaluating morality and aesthetics.[6] Next, want to make someone more likely to choose to clean their hands? Have them describe something crummy and unethical they’ve done. Afterward, they’re more likely to wash their hands or reach for hand sanitizer than if they’d been recounting something ethically neutral they’d done. Subjects instructed to lie about something rate cleansing (but not noncleansing) products as more desirable than do those instructed to be honest. Another study showed remarkable somatic specificity, where lying orally (via voice mail) increased the desire for mouthwash, while lying by hand (via email) made hand sanitizers more desirable. One neuroimaging study showed that when lying by voice mail boosts preference for mouthwash, a different part of the sensory cortex activates than when lying by email boosts the appeal of hand sanitizers. Neurons believing, literally, that your mouth or hand, respectively, is dirty.

Cannabinoids relax the rules of cortical crowd control, but 300 micrograms of d-lysergic acid diethylamide break them completely. This is a clean sweep. This is the Renaissance after the Dark Ages. Dopamine—the fuel of desire—is only one of four major neuro modulators. Each of the neuromodulators fuels brain operations in its own particular way. But all four of them share two properties. First, they get released and used up all over the brain, not at specific locales. Second, each is produced by one specialized organ, a brain part designed to manufacture that one potent chemical (see Figure 3). Instead of watering the flowers one by one, neuromodulator release is like a sprinkler system. That’s why neuromodulators initiate changes that are global, not local. Dopamine fuels attraction, focus, approach, and especially wanting and doing. Norepinephrine fuels perceptual alertness, arousal, excitement, and attention to sensory detail. Acetylcholine energizes all mental operations, consciousness, and thought itself. But the final neuromodulator, serotonin, is more complicated in its action. Serotonin does a lot of different things in a lot of different places, because there are many kinds of serotonin receptors, and they inhabit a great variety of neural nooks, staking out an intricate network. One of serotonin’s most important jobs is to regulate information flow throughout the brain by inhibiting the firing of neurons in many places. And it’s the serotonin system that gets dynamited by LSD. Serotonin dampens, it paces, it soothes. It raises the threshold of neurons to the voltage changes induced by glutamate. Remember glutamate? That’s the main excitatory neurotransmitter that carries information from synapse to synapse throughout the brain. Serotonin cools this excitation, putting off the next axonal burst, making the receptive neuron less sensitive to the messages it receives from other neurons. Slow down! Take it easy! Don’t get carried away by every little molecule of glutamate. Serotonin soothes neurons that might otherwise fire too often, too quickly. If you want to know how it feels to get a serotonin boost, ask a depressive several days into antidepressant therapy. Paxil, Zoloft, Prozac, and all their cousins leave more serotonin in the synapses, hanging around, waiting to help out when the brain becomes too active. Which is most of the time if you feel the world is dark and threatening. Extra serotonin makes the thinking process more relaxed—a nice change for depressives, who get a chance to wallow in relative normality.

Making the most of an experience: Living fully is extolled everywhere in popular culture. I have only to turn on the television at random to be assailed with the following messages: “It’s the best a man can get.” “It’s like having an angel by your side.” “Every move is smooth, every word is cool. I never want to lose that feeling.” “You look, they smile. You win, they go home.” What is being sold here? A fantasy of total sensory pleasure, social status, sexual attraction, and the self-image of a winner. As it happens, all these phrases come from the same commercial for razor blades, but living life fully is part of almost any ad campaign. What is left out, however, is the reality of what it actually means to fully experience something. Instead of looking for sensory overload that lasts forever, you’ll find that the experiences need to be engaged at the level of meaning and emotion. Meaning is essential. If this moment truly matters to you, you will experience it fully. Emotion brings in the dimension of bonding or tuning in: An experience that touches your heart makes the meaning that much more personal. Pure physical sensation, social status, sexual attraction, and feeling like a winner are generally superficial, which is why people hunger for them repeatedly. If you spend time with athletes who have won hundreds of games or with sexually active singles who have slept with hundreds of partners, you’ll find out two things very quickly: (1) Numbers don’t count very much. The athlete usually doesn’t feel like a winner deep down; the sexual conqueror doesn’t usually feel deeply attractive or worthy. (2) Each experience brings diminishing returns; the thrill of winning or going to bed becomes less and less exciting and lasts a shorter time. To experience this moment, or any moment, fully means to engage fully. Meeting a stranger can be totally fleeting and meaningless, for example, unless you enter the individual’s world by finding out at least one thing that is meaningful to his or her life and exchange at least one genuine feeling. Tuning in to others is a circular flow: You send yourself out toward people; you receive them as they respond to you. Notice how often you don’t do that. You stand back and insulate yourself, sending out only the most superficial signals and receive little or nothing back. The same circle must be present even when someone else isn’t involved. Consider the way three people might observe the same sunset. The first person is obsessing over a business deal and doesn’t even see the sunset, even though his eyes are registering the photons that fall on their retinas. The second person thinks, “Nice sunset. We haven’t had one in a while.” The third person is an artist who immediately begins a sketch of the scene. The differences among the three are that the first person sent nothing out and received nothing back; the second allowed his awareness to receive the sunset but had no awareness to give back to it—his response was rote; the third person was the only one to complete the circle: He took in the sunset and turned it into a creative response that sent his awareness back out into the world with something to give. If you want to fully experience life, you must close the circle.

Myth 1: Infants don’t remember anything, so experience in infancy doesn’t really matter. Reality: The infant brain has a huge capacity for memory. Memories from infancy are stored in the brain as implicit memory, which makes up the emotional brain, the unconscious mind, and the foundation for lifelong mental and physical health. Myth 2: Responding to cries spoils an infant or teaches an infant to be dependent. Reality: Responding reliably strengthens a baby’s emotional brain circuits, helps them grow confidently independent, and gives them the gift of stress regulation for life. Myth 3: Babies can and need to learn to self-soothe, which means go from a state of high stress to a state of safety on their own. Reality: Babies cannot self-soothe because they do not have the brain parts to do so until way beyond infancy. Myth 4: Babies are resilient, so experience in infancy doesn’t matter. Reality: Experience in infancy matters. It interacts with genes to influence mental health. Myth 5: We can’t make a difference to our baby’s mental health outcomes if our baby inherits mental health genetics and intergenerational trauma through epigenetics. Reality: Nurture makes an impact on inherited DNA and epigenetics to reduce or silence mental health effects. Myth 6: Everyone falls in love with and knows what to do with their baby right away. Reality: Lots of time touching, smelling, and looking into your baby’s eyes slowly builds your love, knowledge, and relationship with your baby. Myth 7: Having a baby impairs your brain function. Reality: Having a baby changes your brain to give you nurturing superpowers. Myth 8: Being with my baby is doing nothing. Reality: Being with my baby is vital brain-building, circuit-sculpting, cycle-starting activism for my baby’s future. Myth 9: Only pay attention to your baby’s stress and emotions when there’s a reason for them. Reality: All of your baby’s stress and emotions need to feel welcome and safe. Myth 10: Since my baby will be with a grandparent, a nanny, or at daycare, I should reduce my care at home to prepare them. Reality: Providing my baby with as much nurture as possible when we are together is what they need to build their brain. Myth 11: You need to buy things for your baby’s brain development. Reality: Your presence is the key to your baby’s brain development. Myth 12: I need swings, seats, and containers to take care of my baby. My baby needs lots of classes and socialization to thrive. Reality: The sensory experiences from my body are the only thing my baby needs. Myth 13: I should feed my baby on a schedule. Reality: Feed your baby when their body is experiencing physiological signals of hunger and showing hunger cues. Myth 14: Breastfeeding or body feeding past six or twelve or twenty-four or thirty-six months is extra, spoiling, or for no reason. Reality: Breastfeeding or body feeding at six or twelve or twenty-four or thirty-six months is brain-building and nurturing. Myth 15: Holding a baby is doing nothing. Reality: Holding a baby is seriously hard and brain-building work. Myth 16: Newborn babies are happy with a swaddle, hat, pacifier, and bassinet. Reality: Newborns are happy on someone’s skin, chest-to-chest, covered by a blanket—no swaddle, hat, pacifier, or bassinet needed. Myth 17: Babies’ stress and emotions don’t matter and can be ignored. Reality: Babies feel transformational stress and a huge range of emotions that influence how their brains and bodies develop. Myth 18: If we respond to our crying, clinging babies, we teach them that that behavior is good, so they learn to cry and cling more. Reality: When we respond to crying and clinging, babies cry less, and we build the infant brain to be more independent later. Myth 19: There’s no difference if I hold my crying baby; they’re crying anyway. Reality: Holding my crying baby provides a nurture bath to their brain regardless of how long they cry...

Activity will build greater self-efficacy—the belief that you have some mastery over the events in your life and can better meet challenges as they arise.

A carefully planned sensory diet, the optimum sensorimotor activities you need to feel alert and in effortless control and to perform at your peak can provide an electrochemical fix that offers short-term and long-term relief.1

Just as you learned helplessness, you can learn hope and optimism. Activity will build greater self-efficacy—the belief that you have some mastery over the events in your life and can better meet challenges as they arise.

Sensations are truly intrinsic, in that they can also be attainedor obtainedin the absence of activation of sensory pathways. During dreaming we feel many different sensations (Zadra et al. 1998), yet none of the things we feel in our dreams comes via the pathways that convey such sensations during the waking state.

The sensory pathways do not execute sensations; they only serve to inform the internal context about the external world; during dream sleep they do not even do this. In both states, sensation is a construct given by the intrinsic activity of the brain, within the momentary internal context given by the thalamocortical system.

The whole shtick of scientism revolves around sensory evidence. How many times must it be said that there is no such thing as self-explanatory sensory evidence? All evidence must be interpreted, and the interpretation is not a perceiving activity but a judging activity. The catastrophic error that worshipers of scientism (autistic sensing types) commit is that they privilege perceiving over judging. They believe that perception is the most important thing, and that judgment must be directed to the maximum degree possible at the perception, and minimize and indeed eliminate any reference to anything that has not been perceived. For worshipers of scientism, perception comes first, and judging is secondary, determined by perceiving. That is what empiricism is all about. It claims that all knowledge comes from experience, that there are no innate ideas, and it revolves around synthetic propositions and a posteriori knowledge. Rationalism, by total contrast, asserts that knowledge comes from logical, rational deduction and that innate ideas form the only secure basis for knowledge. It deals with analytic propositions and a priori knowledge.

The root of all evil is misunderstanding the nature of self and other by actively ignoring the interdependence of self and other. Evil comes from turning away from the vivid world of creation, where the self can never remain separate from other beings. It is a denial of the ever-changing flux of sensory experience. Evil is a turning away from life. The full realization of refraining from evil comes with waking up to the teaching of interdependence.

If your long path is short-circuited by stress, and your brain is using the short path instead, you might be so alarmed at the mere thought of a shark that you have a panic attack just thinking about taking a swim in the ocean. All the body’s machinery of FFF then gets engaged by this imaginary threat, just as if you were nose to nose with Jaws. Your gut clenches, your heart races, your breathing becomes fast and shallow, and your focus narrows to the point where you can’t think about anything other than the threat. This takes a huge biological toll on the body. High adrenaline produces dramatic reductions in life span. Stressed people have much more disease and live much shorter lives than unstressed people. Whatever form stress takes—depression, anxiety, or PTSD—correlates with higher rates of cancer, diabetes, and heart disease. The deficits in the life spans of stressed people are measured in decades rather than years. In meditators, the amygdala is quiet. It becomes even quieter with practice. The difference in amygdala activation between the longest-term meditators and their less-experienced peers has been measured. The adepts show 400% less reactivity to stressful events. But even in novices who practice mindfulness for 30 hours over 8 weeks, decreased amygdala activity is found. Other structures within the midbrain or limbic system work together with the hippocampus and amygdala. One of them, the thalamus, is like a relay station. Close to the corpus callosum, it identifies information coming in from the senses like touch, hearing, and taste, and directs it to the consciousness centers of the prefrontal cortex. The thalamus typically becomes more active during meditation, as it works harder to suppress sensory input (like “that buzzing mosquito” or “this chair is too hard”) that pulls us out of Bliss Brain. With the hippocampus regulating emotion, the thalamus regulating sensory input, and the long path in good working order, stress-inducing signals aren’t sent to the amygdala. In turn, all the body’s FFF machinery remains offline. This produces corresponding biological benefits. Heart rhythm is even. Respiration is deep and slow. Digestion is effective. Immunity is high. That’s why so many studies show pervasive health and longevity benefits among meditators.

The insula also gives rise to empathy. People who are more sensitive to emotional cues from others have greater insula activation and score higher on tests of empathy. And the insula lights up during meditation sessions, especially when the meditator is feeling kindness and compassion. As the meditator expands his definition of connection to include other people and eventually the entire universe, he feels one with everything. In the words of a comprehensive meditation review, “the habitual reified dualities between subject and object, self and other, in-group and out-group dissipate.” As he expands the borders of his tent to infinity, massive changes occur in his brain activity. Insula Activation Benefits Increases Decreases Elevated emotional states Anger Motor control Fear Kindness Anxiety Compassion Depression Empathy Addiction Longevity Chronic pain Immunity Happiness Love Sensory enjoyment Introspection Sense of fulfillment Feelings of connectedness Focus Self-awareness As well as mediating our empathy and compassion circuits, the insula has several other functions. It collects information from a far-flung network of receptors inside our body as well as from our skin. It then stimulates feelings such as hunger that then prompt actions such as seeking food. The dark side of this mechanism is that it can stimulate cravings for drugs, tobacco, and alcohol. Addicts show increased insula activation even before consuming their drug of choice. The insula also lights up when we feel pain or even anticipate feeling pain. Meditators are more “in the moment” when it comes to physical pain, releasing it more quickly. They may also experience overwhelming cravings, as we’ll see in Chapter 5. These are positive cravings directing them toward the ecstatic states found in Bliss Brain.

Big bundles of neurons conduct information up through the spinal cord into the brain. Sitting at the top of this conduit is the thalamus. In Chapter 3, I compared the thalamus to a relay station, conducting information from the senses to the prefrontal cortex. During meditation, the thalamus is active, as meditators suppress sensory input that might pull them out of Bliss Brain. Andrew Newberg finds that one of the two lobes of the thalamus is often more active than the other. One interpretation of this activity may be the meditator’s awareness that she is more than her body and that she is connected to nonlocal mind, not just her senses. It’s the thalamus that is telling us what is and isn’t reality, and this is affected by the larger reality in which the meditator is absorbed. In long-term meditators, this asymmetry persists when they open their eyes. As the meditator experiences oneness, the universe will, in Newberg’s words, “be sensed as real. But it will not be a ‘symmetrical’ reality. Instead, it will be perceived ‘asymmetrically,’ meaning that the reality will appear different from one’s normal perception.” The nonlocal universe may be perceived as more real than local sensory reality and, as Newberg observes, “The more frequently a person engages in meditative self-reflection, the more these reality centers [like the thalamus] change.

If you've suffered an anxiety attack, maybe you've encountered the grounding techniques of the five senses. What's one thing you smell? Tell me two things you hear. There is a mysterious entanglement between our welfare and our capacity to ground ourselves in a particular place. We are meant to be connected to our where, to the sensory experience of it. The simple beholding of place can slow your heart and steady your breath. It is quite the protective force.

There is no such tiny “Cartesian Theater” in the brain; conscious experience is generated by a vastly complex, distributed network that synchronizes and adjusts its activity by the millisecond. As far as we can tell, certain patterns of activity in this distributed network give rise to conscious experience. But fundamentally, this network’s activity is self-contained and the feeling of a unified flow of consciousness you have is not just from the processing of sensory information. The experience you have right now is a unique creation of your brain that has transformed data from your body into something closer to a hallucination. To break down this seemingly obvious point that we will deal with very often in this book and that I myself struggle to understand: the existence of our experience is real, but the contents of this experience exist only in your brain. Some philosophers call this “irreducible subjectivity,” which means that no totally objective theory of human experience may be possible. The contents of your experience are not representations of the world, but your experience is part of the world. By altering this process with molecules like psilocybin or LSD we can become aware of different aspects of our perceptions. By perturbing consciousness and observing the consequences, we can gain insight into its normal functioning. This is again not to say that consciousness is not real; there can be no doubt that I am conscious as I write this sentence. However, it is the relationship between consciousness and the external world that is more mysterious than one might assume. It is often supposed that cognition and consciousness result from processing the information from our sensory systems (like vision), and that we use neural computations to process this information. However, following Riccardo Manzotti and others such as the cognitive neuroscientist Stanislas Dehaene, I will argue that computations are not natural things that can cause a physical phenomenon like consciousness. When I read academic papers on artificial or machine intelligence, or popular books on the subject, I have not found anyone grappling with these strange “facts” about human consciousness. Either consciousness is not mentioned, or if it is, it is assumed to be a computational problem.

chapter 37 exercise sucks i blame PE class as the first offender. I really do. At such an early age kids who love to play active games are made to run laps instead. Okay, maybe that isn’t every school, but it was certainly the first time I remember someone divorcing physical activity from fun and creating the demon that is exercise. Then diet culture came along and told us the reason we should be engaging this exercise is primarily to keep our bodies thin and attractive. These things have really wrecked our relationship to joyful body movement. If you are motivated to an activity by body shame, experience the activity as a chorus of unpleasant sensory experiences (pain, boredom, and sweat are my three least favorite things in the world), and then end with no immediate results, why on earth would you like that activity or want to do it ever again?

Children develop strength when they have daily opportunities to activate and use big muscle groups in a variety of ways. For instance, when babies have plenty of time to be on the ground day after day, they build strength simply by interacting with the environment around them. They reach for objects, attempt to kick things, push up for a better view, and roll over for a new perspective. They don’t need to do formal baby exercises that so many parenting forums recommend; simply moving about in a sensory-rich, yet soothing, environment is more than adequate for developing muscles naturally.

The gateway to living in the present is sensory activity. It is what keeps you rooted in the present.

As described by the Association for Contextual Behavioral Science, Acceptance and Commitment Therapy (ACT) is a form of empirically based psychological intervention that focuses on mindfulness. Mindfulness is the state of focusing on the present to remove oneself from feeling consumed by the emotion experienced in the moment. To properly observe yourself, begin by noticing where in your body you experience emotion. For example, think about a time when you felt really sad. You may have felt despair in your chest, or a sense of hollowness in your stomach. If you were angry, you may have felt a burning sensation in your arms. This occurs within everyone, in different variations. A study conducted by Carnegie Mellon University traced emotional responses in the brain to different activity signatures in the body through a functional magnetic resonance imaging (fMRI) scanner. If someone recalled a painful or traumatic memory, the prefrontal cortex and neocortex became less active, and their “reptilian brain” was activated. The former areas of the brain are responsible for conscious thought, spatial reasoning, and higher functions such as sensory perception. The latter is responsible for fight-or-flight responses. This means that the bodily responses caused by your emotions provide an opportunity for you to be mindful of them. Your emotions create sensations in your body that reflect your mind. Dr. Bruce Lipton, a developmental biologist who studies gene expression in relation to environmental factors, released a study on epigenetics that sheds light on this matter. It revealed that an individual’s body cannot heal when it is in its sympathetic state. The sympathetic nervous system, informally known as the fight-or-flight state, is triggered by certain emotional responses. This means that when we are consumed by emotion, an effective solution cannot be found until we shift our mind into reflecting on our emotions.

Try to focus on what you’re feeling and where, and this will ground you in the present moment. By focusing on how you are responding, you essentially remove yourself from being consumed by your emotions in that moment. This brings you back into your sensory perception and moves the response in your brain back into the cortex and neocortex. This transition helps bring you back into a more logical state where emotions are not controlling your reactions.

Store photos of strategies and tools on your phone. You can make a folder with images of tools you find helpful, for example noise cancelling headphones, eye mask, weighted blanket, something to do with a special interest. When stressed, just scroll through the photos in the folder to give yourself ideas about what tools to use. It’s likely that as soon as you see the tool that will work for you, you will know it. You can make different folders for different activities, such as ‘Quick Calm Plan for Home’, ‘Quick Calm Plan for Work’ etc. If you scroll through the images before you go out, it will help you not to forget any tools you want to bring with you.

Traumatized people are often afraid of feeling. It is not so much the perpetrators (who, hopefully, are no longer around to hurt them) but their own physical sensations that now are the enemy. Apprehension about being hijacked by uncomfortable sensations keeps the body frozen and the mind shut. Even though the trauma is a thing of the past, the emotional brain keeps generating sensations that make the sufferer feel scared and helpless. It’s not surprising that so many trauma survivors are compulsive eaters and drinkers, fear making love, and avoid many social activities: Their sensory world is largely off limits.

Thus the nerve may be taken to be a relay with essentially two states of activity: firing and repose. Leaving aside those neurons which accept their messages from free endings or sensory end organs, each neuron has its message fed into it by other neurons at points of contact known as synapses. For a given outgoing neuron, these vary in number from a very few to many hundred. It is the state of the incoming impulses at the various synapses, combined with the antecedent state of the outgoing neuron itself, which determines whether it will fire or not. If it is neither firing nor refractory, and the number of incoming synapses which “fire” within a certain very short fusion interval of time exceeds a certain threshold, then the neuron will fire after a known, fairly constant synaptic delay. This is perhaps an oversimplification of the picture: the “threshold” may not depend simply on the number of synapses but on their “weight” and their geometrical relations to one another with respect to the neuron into which they feed; and there is very convincing evidence that there exist synapses of a different nature, the so-called “inhibitory synapses,” which either completely prevent the firing of the outgoing neuron or at any rate raise its threshold with respect to stimulation at the ordinary synapses. What is pretty clear, however, is that some definite combinations of impulses on the incoming neurons having synaptic connections with a given neuron will cause it to fire, while others will not cause it to fire. This is not to say that there may not be other, non-neuronic influences, perhaps of a humoral nature, which produce slow, secular changes tending to vary that pattern of incoming impulses which is adequate for firing.

It’s not surprising that so many trauma survivors are compulsive eaters and drinkers, fear making love, and avoid many social activities: Their sensory world is largely off limits.

AGENCY: OWNING YOUR LIFE “Agency” is the technical term for the feeling of being in charge of your life: knowing where you stand, knowing that you have a say in what happens to you, knowing that you have some ability to shape your circumstances. The veterans who put their fists through drywall at the VA were trying to assert their agency—to make something happen. But they ended up feeling even more out of control, and many of these once-confident men were trapped in a cycle between frantic activity and immobility. Agency starts with what scientists call interoception, our awareness of our subtle sensory, body-based feelings: the greater that awareness, the greater our potential to control our lives. Knowing what we feel is the first step to knowing why we feel that way. If we are aware of the constant changes in our inner and outer environment, we can mobilize to manage them. But we can’t do this unless our watchtower, the MPFC, learns to observe what is going on inside us. This is why mindfulness practice, which strengthens the MPFC, is a cornerstone of recovery from trauma.12 After I saw the wonderful movie March

We have talked about how an infant’s brain takes in sensory information to make sense of their world and build associations. And we’ve talked about how we’re deeply relational creatures whose developing brains—starting with the lowest areas—begin to make “memories” of the smells, sounds, and images of “our people.” These memories exist on a very deep, pre-cortical, unconscious level: the way your people talk, the way they dress, the color of their skin. Now remember that your brain is always monitoring your world—both inside and outside—to ensure your survival. And when the brain encounters any unfamiliar experience, its default move is to activate the stress response. Better to be safe than sorry—better to assume that novelty can be a potential threat. Now add to this the fact that the major predator of humans has always been other humans. Our stress response has evolved to be relationally sensitive, such that when we’re with people who have attributes similar to our childhood “clan,” we feel safe. But when we encounter people with attributes that are different from “our people,” the brain’s default is to activate the stress response. When that happens, we feel dysregulated, even threatened.

Infants (one month to twelve months)—Infants benefit from having opportunities throughout the day to be active and outdoors. Physical activity encourages organization of the sensory system and important motor development. Toddlers (twelve months to three years)—Toddlers could benefit from at least five to eight hours worth of active play a day, preferably outdoors. They will naturally be active throughout the day. As long as you provide plenty of time for free play, they will seek out the movement experiences they need in order to develop. Preschoolers (three years to five years)—Preschoolers could also use five to eight hours of activity and play outdoors every day. Preschoolers learn about life, practice being an adult, and gain important sensory and movement experiences through active play. It’s a good idea to provide them plenty of time for this. School age (five years to thirteen years)—Young children up to preadolescence could benefit from at least four to five hours of physical activity and outdoor play daily. Children in elementary school need movement throughout the day in order to stay engaged and to learn in traditional school environments. They should have frequent breaks to move their body before, during, and after school hours. Adolescents (thirteen years to nineteen years)—Adolescents could benefit from physical activity three to four hours a day. Children in the teens still need to move in order to promote healthy brain and body development, regulate new emotions, and experience important social opportunities with friends out in nature.

To encounter the holy in the ordinary is to find God in the liminal—in spaces where we might subconsciously exclude it, including the sensory moments that are often illegibly spiritual.

Though many of us experience sensory issues, anxiety, meltdowns, and debilitating mental health symptoms, we push as much of that misery into the private realm as possible. Our elaborate veils of coping mechanisms and camouflaging can create the illusion we don’t need help. Often this comes at the expense of giving up on the areas of life where we might need assistance. We may eschew relationships, drop out of grueling academic programs, avoid working in fields that require networking and socializing, or completely disengage from activities that involve using our bodies, because we feel so detached and uncoordinated in them. Most of us are haunted by the sense there’s something “wrong” or “missing” in our lives—that we’re sacrificing far more of ourselves than other people in order to get by and receiving far less in return.

Our brain processes incoming sensory input from the bottom up (see Figures 2 and 10), and if someone has a life with chaotic, uncontrollable, or extreme and prolonged stress, particularly early in life, they’re more likely to act before thinking. Their cortex is not as active, and reactivity in the lower areas of the brain becomes more dominant. It’s very difficult to meaningfully connect with or get through to someone who is not regulated. And it’s nearly impossible to reason with them. This is why telling someone who is dysregulated to “calm down” never works. Oprah: It just makes them angrier. Dr. Perry: Of course. When someone is very upset, words themselves are not very effective. The tone and rhythm of the voice probably has more impact than the actual words. Oprah: So you want to be present with them? Dr. Perry: Yes, it’s best if you can simply be present. If you do use words, it’s best to restate what they’re saying; this is called reflective listening.

The RAS acts as the “editor” of the sensory-based information you’re constantly bombarded with. And just as the editor of a newspaper decides what stories will get page one focus – your RAS decides what stimuli will be sent up to your brain’s higher thinking and emotional centers for attention.

Technology enables frequent, low-stakes testing, an activity that powerfully promotes memory for material. Technology encourages better spacing of study over the time course of the class and helps prevent cramming. Technology facilitates presentation of material in ways that take advantage of learners’ existing knowledge about a topic. Technology facilitates presentation of material via multiple sensory modalities, which, if done in the right ways, can promote comprehension and memory. Technology offers new methods for capturing and holding students’ attention, which is a necessary precursor for memory. Technology supports frequent, varied practice that is a necessary precursor to the development of expertise. Technology offers new avenues to connect students socially and fire them up emotionally. Technology allows us to borrow from the techniques of gaming to promote practice, engagement, and motivation.

Planning. Short-term memory. Attention. At first glance, these three frontal lobe functions can seem like diverse activities that just happen to be packed into the same brain region. But on closer inspection it turns out that they are facets of the same basic phenomenon of 'restraint'. Planning restrains our brains from wandering from a chosen path of activity. Short-term memory retrains sensory cortex from moving on to different imagery. Attention constrains the kind of sensory data admitted to sensory cortex.

Intuitively we all know that it is better to feel than to not feel. Our emotions are not a luxury but an essential aspect of our makeup. We have them not just for the pleasure of feeling but because they have crucial survival value. They orient us, interpret the world for us, give us vital information without which we cannot thrive. They tell us what is dangerous and what is benign, what threatens our existence and what will nurture our growth. Imagine how disabled we would be if we could not see or hear or taste or sense heat or cold or physical pain. To shut down emotions is to lose an indispensable part of our sensory apparatus and, beyond that, an indispensable part of who we are. Emotions are what make life worthwhile, exciting, challenging, and meaningful. They drive our explorations of the world, motivate our discoveries, and fuel our growth. Down to the very cellular level, human beings are either in defensive mode or in growth mode, but they cannot be in both at the same time. When children become invulnerable, they cease to relate to life as infinite possibility, to themselves as boundless potential, and to the world as a welcoming and nurturing arena for their self-expression. The invulnerability imposed by peer orientation imprisons children in their limitations and fears. No wonder so many of them these days are being treated for depression, anxiety, and other disorders. The love, attention, and security only adults can offer liberates children from the need to make themselves invulnerable and restores to them that potential for life and adventure that can never come from risky activities, extreme sports, or drugs. Without that safety our children are forced to sacrifice their capacity to grow and mature psychologically, to enter into meaningful relationships, and to pursue their deepest and most powerful urges for self-expression. In the final analysis, the flight from vulnerability is a flight from the self. If we do not hold our children close to us, the ultimate cost is the loss of their ability to hold on to their own truest selves.

Neuroenology explains how the fluid mechanics of the wine in your mouth and the patterns of your breathing activate your sensory and motor pathways to create the taste of wine and, together with your central brain systems for emotion and memory, generate the whole perception of wine pleasure. We

Change the material environment by altering the availability of amino acids or fats or carbohydrates in the diet of young animal, and the gene-environment interactions that occur will change as well, potentially affecting the structural development of the brain or the activity of hormone-releasing organs, with assorted behavioral consequences for the affected individual. Alter the experiential environment by changing the sensory inputs from the physical environment or from social interactions with other animals, and behavioral development will shift as well.

1. Give your toddler some large tubular pasta and a shoelace.  Show her how to thread the shoelace through the pasta. 2. Take an empty long wrapping paper tube and place one end on the edge of the sofa and the other end on the floor.  Give him a small ball such as a Ping Pong ball to roll down the tube.   3. Give her some individually wrapped toilet tissues, some boxes of facial tissue or some small tins of food such as tomato paste.  Then let her have fun stacking them.     4. Wrap a small toy and discuss what might be inside it.  Give it to him to unwrap. Then rewrap as he watches.  Have him unwrap it again.    5. Cut  such fruits as strawberries and bananas into chunks.  Show her how to slide the chunks onto a long plastic straw.  Then show her how you can take off one chunk at a time, dip it into some yogurt and eat it.   6. Place a paper towel over a water-filled glass.  Wrap a rubber band around the top of the glass to hold the towel in place.  Then place a penny on top of the paper towel in the centre of the glass.  Give your child a pencil to poke holes in the towel until the penny sinks to the bottom of the glass.   7. You will need a small sheet of coarse sandpaper and various lengths of chunky wool.  Show him how to place these lengths of wool on the sandpaper and how the strands stick to it.   8. Use a large photo or picture and laminate it or put it between the sheets of clear contact paper.  Cut it into several pieces to create a puzzle.   9. Give her two glasses, one empty and one filled with water.  Then show her how to use a large eyedropper in order to transfer some of the water into the empty glass.   10. Tie the ends/corners of several scarves together.  Stuff the scarf inside an empty baby wipes container and pull a small portion up through the lid and then close the lid.  Let your toddler enjoy pulling the scarf out of the container.   11. Give your child some magnets to put on a cookie sheet.  As your child puts the magnets on the cookie sheet and takes them off, talk about the magnets’ colours, sizes, etc.   12. Use two matching sets of stickers. Put a few in a line on a page and see if he can match the pattern.  Initially, you may need to lift an edge of the sticker off the page since that can be difficult to do.    13. You will need a piece of thin Styrofoam or craft foam and a few cookie cutters.  Cut out shapes in the Styrofoam with the cookie cutters and yet still keep the frame of the styrofoam intact.  See if your child can place the cookie cutters back into their appropriate holes.        14. Give her a collection of pompoms that vary in colour and size and see if she can sort them by colour or size into several small dishes. For younger toddlers, put a sample pompom colour in each dish.   15. Gather a selection of primary colour paint chips or cut squares of card stock or construction paper.  Make sure you have several of the same colour.  Choose primary colours.  See if he can match the colours.  Initially, he may be just content to play with the colored chips stacking them or making patterns with them.

Hill specifically focuses on my A5: “For Nietzsche, as for Kant, our minds are independent sources of activity, striving to subjugate and reduce to order the sensory states that arise in us” (194).

Just as episodic memory depends on semantic memory, semantic and episodic memory both depend on implicit memory.29 For example, each time we consciously recognize a stimulus, we are drawing upon implicit processes operating in the medial temporal lobe memory system. Sensory cues that activate elements of a memory are stored via the medial temporal lobe system; then, through a process known as pattern completion,30 a memory is assembled in a way that can be retrieved into working memory, where it can be consciously experienced. Although the result is a conscious memory, the processes that package it in such a way to allow it to become conscious content are not consciously accessible. Recall

So as soon as you think a new thought, you become changed—neurologically, chemically, and genetically. In fact, you can gain thousands of new connections in a matter of seconds from novel learning, new ways of thinking, and fresh experiences. This means that by thought alone, you can personally activate new genes right away. It happens just by changing your mind; it’s mind over matter. Nobel laureate Eric Kandel, M.D., showed that when new memories are formed, the number of synaptic connections in the sensory neurons that are stimulated doubles, to 2,600. However, unless the original learning experience is repeated over and over again, the number of new connections falls back to the original 1,300 in a matter of only three weeks. Therefore,

In the traditionally taught view of perception, data from the sensorium pours into the brain, works its way up the sensory hierarchy, and makes itself seen, heard, smelled, tasted, felt—“perceived.” But a closer examination of the data suggests this is incorrect. The brain is properly thought of as a mostly closed system that runs on its own internally generated activity. We already have many examples of this sort of activity: for example, breathing, digestion, and walking are controlled by autonomously running activity generators in your brain stem and spinal cord. During dream sleep the brain is isolated from its normal input, so internal activation is the only source of cortical stimulation. In the awake state, internal activity is the basis for imagination and hallucinations.

Off-line aspects of embodied cognition, in contrast, include any cognitive activities in which sensory and motor resources are brought to bear on mental tasks whose referents are distant in time and space or are altogether imaginary. These include symbolic off-loading, where external resources are used to assist in the mental representation and manipulation of things that are not

brain-friendly training uses the following five general elements to enhance learning: 1. Positive emotional experiences 2. Multi-sensory stimulation and novelty 3. Instructional variety and choices 4. Active participation and collaboration 5. Informal learning environments

The vestibular and auditory systems have a very unique sensory connection. They share a cranial nerve that sends input to the brain. This is the vestibulocochlear nerve. When the brain is receiving auditory input, the vestibular system in being activated, and vice versa. So, incorporating the two into an activity is powerful because when you activate one, the other is ready to rumble! When

A rhyming Nativity narrative. "The donkey who carried Mary to the Nativity calmly focuses on feelings of wonderment surrounding the child’s birth. With huge eyes...the little donkey is utterly adorable. Lines like “a bit of tingle-my-toes. / That’s how the evergreen / smelled to me, / a bit of fresh pine to my nose” offer opportunities for caregivers to extend the reading to sensory activities, though the scent of pine doesn’t seem historically accurate. An uncluttered stable features friendly, curious barn animals that greet baby Jesus along with the three Wise Men. Told in verse, the tale evokes a tender, pleasant mood. ...“I lifted my head / above His hay bed // …and sang of this morning of grace.” Jesus, referred to as “the Baby” and “the Babe,” is tan-skinned, as are his parents. Two of the Wise Men are light-skinned, while one is darker-skinned. A gentle, spare tale, part bedtime story, part Christmas fare. (Picture book. 2-5)" Kirkus Reviews

What all this tells us is that perception reflects the active comparison of sensory inputs with internal predictions. And this gives us a way to understand a bigger concept: awareness of your surroundings occurs only when sensory inputs violate expectations. When the world is successfully predicted away, awareness is not needed because the brain is doing its job well.

You are a miracle of consciousness, a heart beating in your beautiful body, enabling you to perceive and receive this stream of sensory information with appreciation and awe. You, too, are pulsing with energy, activated by the very same Elements animating the stars. Pause to consciously acknowledge the wondrous amalgamation you are, a compilation of complex biological systems that motor your movements inside and out, persistently powering your physical and mental processes, keeping you awake and alive, brimming with potential as a being of peace and of love.

When we discipline with threats—whether explicitly through our words or implicitly through scary nonverbals like our tone, posture, and facial expressions—we activate the defensive circuits of our child’s reactive reptilian downstairs brain. We call this “poking the lizard,” and we don’t recommend it because it almost always leads to escalating emotions, for both parent and child. When your five-year-old throws a fit at the grocery store, and you tower over him and point your finger and insist through clenched teeth that he “calm down this instant,” you’re poking the lizard. You’re triggering a downstairs reaction, which is almost never going to lead anywhere productive for anyone involved. Your child’s sensory system takes in your body language and words and detects threat, which biologically sets off the neural circuitry that allows him to survive a threat from his environment—to fight, to flee, to freeze, or to faint. His downstairs brain springs into action, preparing to react quickly rather than fully considering alternatives in a more responsive, receptive state. His muscles might tense as he prepares to defend himself and, if necessary, attack with freeze and fight. Or he may run away in flight, or collapse in a fainting response. Each of these is a pathway of reactivity of the downstairs brain. And his thinking, rational self-control circuitry of the upstairs brain goes off-line, becoming unavailable in that moment. That’s the key—we can’t be in both a reactive downstairs state and a receptive upstairs state at the same time. The downstairs reactivity holds sway. In this situation, you can appeal to your child’s more sophisticated upstairs brain, and allow it to help rein in the more reactive downstairs brain.

To be in a state of pure consciousness or no-mind does not entail the rejection of or complete detachment from ordinary mental or sensory experience. On the contrary, in a unified state of consciousness, awareness remains established in unbounded silence while simultaneously engaged in the boundaries of everyday activity.

Even though the trauma is a thing of the past, the emotional brain keeps generating sensations that make the sufferer feel scared and helpless. It’s not surprising that so many trauma survivors are compulsive eaters and drinkers, fear making love, and avoid many social activities: Their sensory world is largely off limits.

What is sensory integration therapy? This form of occupational therapy helps children and adults with SPD (sensory processing disorder) use all their senses together. These are the senses of touch, taste, smell, sight, and hearing. Sensory integration therapy is claimed to help people with SPD respond to sensory inputs such as light, sound, touch, and others; and change challenging or repetitive behaviours. Someone in the family may have trouble receiving and responding to information through their senses. This is a condition called sensory processing disorder (SPD). These people are over-sensitive to things in their surroundings. This disorder is commonly identified in children and with conditions like autism spectrum disorder. The exact cause of sensory processing disorder is yet to be identified. However, previous studies have proven that over-sensitivity to light and sound has a strong genetic component. Other studies say that those with sensory processing conditions have abnormal brain activity when exposed simultaneously to light and sound. Treatment for sensory processing disorder in children and adults is called sensory integration therapy. Therapy sessions are play-oriented for children, so they should be fun and playful. This may include the use of swings, slides, and trampolines and may be able to calm an anxious child. In addition, children can make appropriate responses. They can also perform more normally. SPD can also affect adults Someone who struggles with SPD should consider receiving occupational therapy, which has an important role in identifying and treating sensory integration issues. Occupational therapists are health professionals using different therapeutic approaches so that people can do every work they need to do, inside and outside their homes. Through occupational therapy, affected individuals are helped to manage their immediate and long-term sensory symptoms. Sensory integration therapy for adults, especially for people living with dementia or Alzheimer's disease, may use everyday sounds, objects, foods, and other items to rouse their feelings and elicit positive responses. Suppose an adult is experiencing agitation or anxiety. In that case, soothing music can calm them, or smelling a scent familiar to them can help lessen their nervous excitement and encourage relaxation, as these things can stimulate their senses. Seniors with Alzheimer's/Dementia can regain their ability to connect with the world around them. This can help improve their well-being overall and quality of life. What Are The Benefits of Sensory Integration Therapy Sensory integration treatment offers several benefits to people with SPD: * efficient organisation of sensory information. These are the things the brain collects from one's senses - smell, touch, sight, etc. * Active involvement in an exploration of the environment. * Maximised ability to function in recreational and other daily activities. * Improved independence with daily living activities. * Improved performance in the home, school, and community. * self-regulations. Affected individuals get the ability to understand and manage their behaviours and understand their feelings about things that happen around them. * Sensory systems modulation.

We have seen that a toddler needs to be surrounded to build fixed landmarks in his mind; he needs to move, to discover the environment by himself through the five senses, and he needs to do. All other needs of the toddler are always related to the sensory periods and are: Need for direct contact with the mother; Need to feel protected and safe; Need to develop relationships; Need to find stable reference points; Need its biological rhythms to be respected; Need for self-awareness as an individual; Need for freedom and independence; Need for a tailored space; Need for concentration; Need to use hands; Need to experience nature; Need for silence.

Human consciousness is characterized by a strong extravert tendency that reaches for objects via the senses. Hence the Yoga masters call for the control of both the mind and the senses, citta-nigraha and indriya-nigraha. Buddhist Yoga speaks of three types of “thirsting” (trishna), or grasping: (1) thirsting for things of the world, (2) thirsting for rebirth, and (3) thirsting for liberation. While thirsting for liberation is preferable over the other two, it still represents a limitation. Therefore it, too, must be overcome. Nirvāna (nonblowing) was originally defined as the nonblowing of the wind of desire—for anything, including the impulse toward liberation. Nirvāna is realized only when every form of grasping is transcended. According to an old Buddhist model, human life unfolds as a play of twelve factors of dependent origination (pratītya-samutpāda): Ignorance (avidyā), which gives rise to Volitional activity (samskāra), which can be bodily, vocal, or merely mental and which represents either meritorious or demeritorious karma; this leads to Consciousness (vijnāna), which causes “Name and form” (nāma-rūpa), which stands for what today is called the body-mind as a whole and which gives rise to The “six bases” (shad-āyatana) consisting of the five senses and that part of the mind which processes sensory input; this leads to Contact (sparsha) with sense objects, which gives rise to Feeling (samveda), comprising pleasant, unpleasant, or neutral sensations; this evokes Craving (trishna), or the desire to unite with pleasant or separate from unpleasant experiences, which leads to Grasping (upadāna), which consists in one’s holding onto specific experiences, views, behaviors, or the sense of self as such; this causes “Becoming” (bhava), or a particular state of existence that corresponds to a person’s inner constitution, which leads to Birth (jāti), or the actual incarnation as a specific individual, which brings Ageing and death (jarā-marana). This causal nexus seeks to explain cyclic existence (samsāra) in terms of an individual’s journey from birth to death to rebirth, ad infinitum. This model makes it clear that cyclic existence is not due to any outside agency but the human mind itself. In other words, we are creating our destiny in every moment. Yoga further tells us that samsāra is not inevitable but that we can stop the vicious cycle by modifying our volitional activity and behavior. This good news is fundamental to all forms of Yoga. Greed is a phenomenon of the unregenerate psyche, which is under the spell of the conditioned nexus and has not taken control of its own destiny. Freedom from greed comes with nongrasping (aparigraha), which is based on the recognition that we are inherently complete and need nothing for our perfection.

Future motor neurons are located ventrally, and form the ventral roots of the spinal cord. The neurons of the sensory nervous system develop from neural crest cells. The dorso-ventral organization of the spinal cord is produced by Sonic hedgehog protein signals from ventral regions such as the notochord. Sonic hedgehog forms a gradient of activity from ventral to dorsal in the neural tube, and acts as the ventral patterning positional signal. As well as being organized along the dorso-ventral axis, neurons at different positions along the antero-posterior axis of the spinal cord become specified to serve different functions. The antero-posterior specification of neuronal function in the spinal cord was dramatically illustrated some 40 years ago by experiments in which a section of the spinal cord that would normally innervate wing muscles was transplanted from one chick embryo into the region that normally serves the legs of another embryo. Chicks developing from the grafted embryos spontaneously activated both legs together, as though they were trying to flap their wings, rather than activating each leg alternately as if walking. These studies showed that motor neurons generated at a given antero-posterior level in the spinal cord had intrinsic properties characteristic of that position. The spinal cord becomes demarcated into different regions along the antero-posterior axis by combinations of expressed Hox genes. A typical vertebrate limb contains more than 50 muscle groups with which neurons must connect in a precise pattern. Individual neurons express particular combinations of Hox genes, which determine which muscle they will innervate. So all together, expression of genes resulting from dorso-ventral position together with those resulting from antero-posterior position confers a virtually unique identity on functionally distinct sets of neurons in the spinal cord.

Our brain processes incoming sensory input from the bottom up, and if someone has a life with chaotic, uncontrollable, or extreme and prolonged stress, particularly early in life, they're more likely to act before thinking. Their cortex is not as active, and reactivity in the lower areas of the brain becomes more dominant.

Kolb’s experiential learning cycle is a widely used explanation on how effective learning takes place (Kolb, 1983; Zull, 2002). Kolb’s cycle has four stages – namely, the concrete experience stage, reflective observation stage, abstract conceptualisation stage, and active experimentation stage. All four stages play important roles in accomplishing successful and effective learning. Kolb’s theory explains how different parts of the brain function together to affect effective learning; concrete experience is sensed through the sensory cortex; reflective observation is performed using the back integrative cortex; abstract conceptualisation is done using the frontal integrative cortex; and active experimentation is performed using motor cortex (Zull, 2002).

OM CHANTING Various studies have shown that OM chanting deactivates the limbic part of the brain responsible for our basic emotions (fear, pleasure, anger) and our impulses (hunger, sex, dominance and care of offspring). Since the effectiveness of OM chanting is associated with the experience of vibrations around the ears, scientists have suggested that these sensations are transmitted through the auricular branch of the vagus nerve. As the vagus nerve branches off into the inner ear and larynx, controlling the opening and closing of the vocal cords and tone of the sound, it appears that this is stimulated during the vocalization of the O and M sounds. In addition, by performing chanting in exhalation, the vagus nerve is activated in its role as manager of the parasympathetic system. In addition, chanting, by facilitating the lengthening of the exhalation, further amplifies the effect on the parasympathetic system. This is why this practice helps to calm and relax the body and mind. -Find a quiet place to sit comfortably. -A good position is to sit with your legs crossed and your back straight. -Wear comfortable cotton clothes that do not tighten any part of your body. All body channels should be free and comfortable. Place the palm of your right hand (facing upwards) on the palm of your left hand at navel level. Close your eyes for a few minutes and relax your mind and body. Slowly feel the vibrations that occur in every part of your body. When the vibrations become more intense, start breathing deeply. Hold your breath for a second and then slowly exhale. Initially count to 7 as you exhale. This ought to be duplicated thrice. As you exhale the third time, sing "oooooooooo..." Feel the vibrations in your abdomen (and under your chest). After exhaling, relax for 2 seconds. Breathe in again (slow, deep breaths). As you exhale sing "ooooo..." and feel the vibrations in your chest and neck. After exhaling, relax for 2 seconds. Inhale again (long, deep breath). As you exhale, sing "mmmmmmmm...". Feel the vibrations in your head and neck. After exhaling, relax for 2 seconds. Inhale again and as you exhale say "oooommmm..." or "aaauuummm...". About 80% of the sound should be "aaauuu..." and 20% should be "mmmm...". Repeat the previous steps 3 times (you can do it up to 9 times). After the Om meditation, relax and concentrate on your regular breathing for about 5 minutes. TIPS -Wearing white clothes and being in a white environment will improve your experience. But the rule of white is not fundamental. -A good place could be a quiet room or a garden with shade. Your eyes, ears or other sensory organs should not be disturbed. -Do not consume alcohol for at least 8-10 hours before meditation. -It would be better not to eat or drink anything for at least 2 hours before meditation. The body's channels should not be blocked in order to achieve maximum results. This applies especially to the digestive system. -The best times for this meditation are early in the morning or late at night. -For beginners, singing "aum" can cause dizziness. It is recommended to proceed slowly and try to learn one step at a time. In this way you will prepare body and mind for the next step. -It is very important to open your eyes slowly when your breathing has stabilized. -If you cannot sit on the floor, you can try sitting on a bed or a chair. The most important thing is to keep your back straight. -Doing this kind of meditation in a group brings more peace and harmony to all members than doing it alone.

If you feel that you can strengthen your vibes on your own without any support, you’re kidding yourself. Empaths and intuitives especially need supportive people to help us remain true to ourselves. We can easily get lost in other people’s energy and become drained, overwhelmed, and confused. I encourage you to actively seek out your soul supporters (those other six-sensory people who are listening to their spirit) as part of your effort to strengthen your inner channel. Find people you can connect with, who will listen to you, respect your vibes, and keep them safe and protected from negative judgment, including your own—in other words, your team. These people do exist, and you need to connect with and invite them into your life as fast as possible. Intuitive people are most comfortable with kindred spirits—we don’t do as well alone. As I like to say, even Jesus Christ picked 12 helpers before he went to work.

The so-called perceptual ‘stimulus’ and motor ‘response’ cannot be considered separately, outside the context of their interaction, though Dewey hints that indeed the motor element – normally seen as the response – may be primary. Perception is an active, not a passive process – or better, it is a profoundly interactive process. Movement lies behind, and in, every one of our senses. This idea has gathered further scientific backing in recent years. The Colombian neuroscientist Rodolfo Llinás has argued, starting from the examination of simple marine invertebrates such as the sea squirt, that the capacity for motion underlies all knowledge: What I must stress here is that the brain’s understanding of anything, whether factual or abstract, arises from our manipulations of the external world, by our moving within the world and thus from our sensory-derived experience of it.230 Similarly neuroscientist György Buzsáki claims that perception is founded on motion and cognition, not motion and cognition founded on perception. He regards activity ‘as not only interwoven with perception but prior to perception, prior both in terms of evolution and in terms of initiating processes within and outside the organism that result in the organism’s perceiving.’231 In relation to the evolutionary claim, he points to some primitive sea animals that are capable only of a rhythmic movement of cilia to bring in nutrients, with no (presumed) perceptual abilities at all.232

Bliss Consciousness may be lived at all times, it is necessary that it should not be lost when the mind comes out of meditation and engages in activity. For this to be possible the mind has to become so intimately familiar with the state of Being that It remains grounded in the mind at all times, through all the mental activity of thinking, discriminating, and deciding, and through all phases of action on the sensory level. For this in turn, it is necessary that the process of gaining Transcendental Consciousness through meditation

A great way to open the dopamine floodgate is to watch and listen to inspirational stuff about the activity you are prone to quitting at. Unlike meme-turds, videos are a more immersive sensory experience, and virtually all capitalize on the dopaminergic power of music. Music has the ability to not just arouse pleasurable feelings but also increase craving or wanting—two critical elements of sports motivation.

Polyvagal Theory suggests that sensory trauma may thus be experienced in the autistic person’s body as fluctuating yet persistent SNS activation or fluctuating yet persistent PNS disconnection (dorsal vagus), or a combination of the two, with the range of accompanying physiological changes that each implies.

Neurotypical brains engage in sensory adaptation and habituation: the longer they are in the presence of a sound, smell, texture, or visual cue, the more their brain learns to ignore it, and allow it to fade into the background. Their neurons become less likely to be activated by a cue the longer they are around it. The exact opposite is true for Autistic people: the longer we are around a stimulus, the more it bothers us.

The rattlesnake represents the very acme of serpentine sophistication. It has superlative sensing organs that exploit infra-red and chemo-sensory stimuli to enable it to locate its prey. It is armed with one of the most powerful of all venoms with which it can inject its victims with surgical precision. It is long-lived and produces its young fully formed and immediately capable of fending for themselves. But it has one vulnerability, one way in which human beings who see rattlesnakes as a threat to their own dominance are able to attack it. In North America, in the northern part of the rattlesnake’s range, winters can be so severe that a cold-blooded snake cannot remain active. So many species that are common elsewhere in North America do not spread far north. Rattlers are among the few that do. They survive the winter by another special adaptation. They have developed the ability to hibernate. On the prairies of the mid-West and north into Canada, they choose to do so in the burrows of prairie dogs, rodents related to marmots. Elsewhere in the woodlands, they find outcrops of rocks that are riven by deep clefts. But such places are not abundant. As autumn approaches and temperatures fall, great numbers of rattlesnakes set out on long cross-country journeys of many miles following traditional routes to the places where they and their parents before them hibernate each year. Some of these wintering dens may contain a thousand individuals. So those human beings who hate snakes and who, in spite of the rattler’s sophisticated early warning system, believe that they are a constant and lethal threat, are also able, at this season of the year, to massacre rattlesnakes in thousands. As a consequence one of the most advanced and wonderfully sophisticated of all snakes — perhaps of all reptiles — is now, in many parts of the territories it once ruled, in real danger of extinction.

When something interesting activates the dopamine system, we snap to attention. If we are able to activate our H&N system by shifting our focus outward, the increased level of attention makes the sensory experience more intense. Imagine walking down a street in a foreign country. Everything is more exciting, even looking at ordinary buildings, trees, and shops. Because we are in a novel situation, sensory inputs are more vivid. That’s a large part of the joy of travel. It works in the opposite direction, too. Experiencing H&N sensory stimulation, especially within a complex environment (sometimes called an enriched environment), makes the dopaminergic cognitive facilities in our brains work better. The most complex environments, those that are most enriched, are usually natural ones.

Children requiring primary somatosensory interventions are likely are to display frequent sensory misperceptions, appetite, feeding, or metabolism problems, persistent somatic or visceral dysregulation, fine or gross motor movement or balance impairment, sleep problems, or endocrine issues. Such anomalies will be in excess of normal for the developmental age. The treatment protocol will emphasize somatosensory experiences, self-regulation, and movement interventions, all of which provide the appropriate nature and pattern of activation to help these lower networks change. Language, reasoning, logic, and understanding are de-emphasized in favor of core regulatory functions. The somatosensory activities must be carried out in a richly positive relational context (Core Element 3) as the activity itself is insufficient for positive developmental growth and neural organization. Sensory activities must be planned and scheduled at specific times each day for short periods of about 10 to 15 minutes. Pick activities the child will enjoy, as children will not repeat those that are unrewarding. The activity, environment, and method may need to modified periodically to keep them fresh, attractive, and fun. Never force the child into an activity if he or she is uncomfortable with it. Take baby steps if the child is uncomfortable. Find safe ways for the child to engage in and experience the activity.

Moruzzi and Magoun realized that the brain contains a system—which they called the reticular activating system—that extends from the brain stem and midbrain to the thalamus, and from the thalamus to the cortex. This system carries the sensory information from the various sensory systems necessary for the conscious state, and distributes it diffusely to the cerebral cortex (fig. 11.3). But while the reticular activating system is necessary for wakefulness, it is not concerned with the content of conscious processing, that is, with the content of awareness. Figure 11.3.

The child who feels uncomfortable in his own skin may have poor motor planning, or dyspraxia. He may move awkwardly and have difficulty planning and organizing his movements. Thus, he may shun the very activities that would improve his praxis.

Perceptual motor therapy provides integrated movement experiences that remediate gross-motor, fine-motor, and visual discrimination problems. Activities, including sensory-input techniques, stimulate left/right brain communication to help the child interpret incoming information to the nervous system. Goals are to develop more mature patterns of response to specific stimuli, improve motor skills and balance, and stimulate alternate routes to memory and sequencing for those children who do not respond to the methods taught in the conventional classroom.

Activities to Develop the Tactile Sense Rub-a-Dub-Dub—Encourage the child to rub a variety of textures against her skin. Offer different kinds of soap (oatmeal soap, shaving cream, lotion soap) and scrubbers (loofah sponges, thick washcloths, foam pot-scrubbers, plastic brushes). Water Play—Fill the kitchen sink with sudsy water and unbreakable pitchers and bottles, turkey basters, sponges, eggbeaters, and toy water pumps. Or, fill a washtub with water and toys and set it on the grass. Pouring and measuring are educational and therapeutic, as well as high forms of entertainment. Water Painting—Give the child a bucket of water and paintbrush to paint the porch steps, the sidewalk, the fence, or her own body. Or, provide a squirt bottle filled with clean water (because the squirts often go in the child’s mouth). Finger Painting—Let the sensory craver wallow in this literally “sensational” activity. Encourage (but don’t force) the sensory avoider to stick a finger into the goop. For different tactile experiences, mix sand into the paint, or place a blob of shaving cream, peanut butter, or pudding on a plastic tray. Encourage him to draw shapes, letters, and numbers. If he “messes up,” he can erase the error with his hand and begin again. Finger Drawing—With your finger, “draw” a shape, letter, number, or design on the child’s back or hand. Ask the child to guess what it is and then to pass the design on to another person. Sand Play—In a sandbox, add small toys (cars, trucks, people, and dinosaurs), which the child can rearrange, bury, and rediscover. Instead of sand, use dried beans, rice, pasta, cornmeal, popcorn, and mud. Making mud pies and getting messy are therapeutic, too.

Feelie Box—Cut a hole in a shoebox lid. Place spools, buttons, blocks, coins, marbles, animals, and cars in the box. The child inserts a hand through the hole and tells you what toy she is touching. Or, ask her to reach in and feel for a button or car. Or, show her a toy and ask her to find one in the box that matches. These activities improve the child’s ability to discriminate objects without the use of vision. “Can You Describe It?”—Provide objects with different textures, temperatures, and weights. Ask her to tell you about an object she is touching. (If you can persuade her not to look at it, the game is more challenging.) Is the object round? Cool? Smooth? Soft? Heavy? Oral-Motor Activities—Licking stickers and pasting them down, blowing whistles and kazoos, blowing bubbles, drinking through straws or sports bottles, and chewing gum or rubber tubing may provide oral satisfaction. Hands-on Cooking—Have the child mix cookie dough, bread dough, or meat loaf in a shallow roasting pan (not a high-sided bowl). Science Activities—Touching worms and egg yolks, catching fireflies, collecting acorns and chestnuts, planting seeds, and digging in the garden provide interesting tactile experiences. Handling Pets—What could be more satisfying than stroking a cat, dog or rabbit? People Sandwich—Have the “salami” or “cheese” (your child) lie facedown on the “bread” (gym mat or couch cushion) with her head extended beyond the edge. With a “spreader” (sponge, pot scrubber, basting or vegetable brush, paintbrush, or washcloth) smear her arms, legs, and torso with pretend mustard, mayonnaise, relish, ketchup, etc. Use firm, downward strokes. Cover the child, from neck to toe, with another piece of “bread” (folded mat or second cushion). Now press firmly on the mat to squish out the excess mustard, so the child feels the deep, soothing pressure. You can even roll or crawl across your child; the mat will distribute your weight. Your child will be in heaven.

Activities to Develop the Vestibular System Rolling—Encourage your child to roll across the floor and down a grassy hill. Swinging—Encourage (but never force) the child to swing. Gentle, linear movement is calming. Fast, high swinging in an arc is more stimulating. If the child has gravitational insecurity, start him on a low swing so his feet can touch the ground, or hold him on your lap. Two adults can swing him in a blanket, too. Spinning—At the playground, let the child spin on the tire swing or merry-go-round. Indoors, offer a swivel chair or Sit ’n Spin. Monitor the spinning, as the child may become easily overstimulated. Don’t spin her without her permission! Sliding—How many ways can a child swoosh down a slide? Sitting up, lying down, frontwards, backwards, holding on to the sides, not holding on, with legs straddling the sides, etc. Riding Vehicles—Trikes, bikes, and scooters help children improve their balance, motor planning, and motor coordination. Walking on Unstable Surfaces—A sandy beach, a playground “clatter bridge,” a grassy meadow, and a waterbed are examples of shaky ground that require children to adjust their bodies as they move. Rocking—Provide a rocking chair for your child to get energized, organized, or tranquilized.

Activities to Develop the Visual System Making Shapes—Let your child draw or form shapes, letters, and numbers in different materials, such as playdough, finger paint, shaving cream, soap foam, sand, clay, string, pudding, or pizza dough. Mazes and Dot-to-Dot Activities—Draw mazes on paper, the sidewalk, or the beach. Have the child follow the mazes with his finger, a toy car, a crayon, a marker, or chalk. On graph paper, make dot-to-dot patterns for the child to follow. Peg Board—Have the child reproduce your design or make his own. Cutting Activities—Provide paper and scissors and have your child cut fringe and strips. Draw curved lines on the paper for her to cut. Cutting playdough is fun, too. Tracking Activities—Lie on your backs outside and watch birds or airplanes, just moving your eyes while keeping your heads still. Jigsaw Puzzles! Block Building!!

Our senses give us the information we need to function in the world. Their first job is to help us survive. Their second job, after they assure us that we are safe, is to help us learn how to be active, social creatures. The senses receive information from stimuli both outside and inside our bodies. Every move we make, every bite we eat, every object we touch produces sensations. When we engage in any activity, we use several senses at the same time. The convergence of sensations—especially touch, body position, movement, sight, sound, and smell—is called intersensory integration. This process is key and tells us on the spot what is going on, where, why, and when it matters, and how we must use or respond to it. The more important the activity, the more senses we use. That is why we use all our senses simultaneously for two very important human activities: eating and procreating. Sometimes our senses inform us that something in our environment doesn’t feel right; we sense that we are in danger and so we respond defensively. For instance, should we feel a tarantula creeping down our neck, we would protect ourselves with a fight-or-flight response. Withdrawing from too much stimulation or from stimulation of the wrong kind is natural. Sometimes our senses inform us that all is well; we feel safe and satisfied and seek more of the same stimuli. For example, we are so pleased with the taste of one chocolate-covered raisin that we eat a handful. Sometimes, when we get bored, we go looking for more stimulation. For example, when we have mastered a skill, like ice skating in a straight line, we attempt a more complicated move, like a figure eight. To do their job well, so that we respond appropriately, the senses must work together. A well-balanced brain that is nourished with many sensations operates well, and when our brain operates smoothly, so do we. We have more senses than many people realize. Some sensations occur outside our bodies, and some inside.

The Out-of-Sync Child Has Fun (Perigee, 2006), The Goodenoughs Get in Sync (Sensory World, 2010), Growing an In-Sync Child (Perigee, 2010), and In-Sync Activity Cards (Sensory World, 2012).

Activities to Develop the Proprioceptive System Lifting and Carrying Heavy Loads—Have the child pick up and carry soft-drink bottles to the picnic; laundry baskets upstairs; or grocery bags, filled with nonbreakables, into the house. He can also lug a box of books, a bucket of blocks, or a pail of water from one spot to another. Pushing and Pulling—Have the child push or drag grocery bags from door to kitchen. Let him push the stroller, vacuum, rake, shove heavy boxes, tow a friend on a sled, or pull a loaded wagon. Hard muscular work jazzes up the muscles. Hanging by the Arms—Mount a chinning bar in a doorway, or take your child to the park to hang from the monkey bars. When she suspends her weight from her hands, her stretching muscles send sensory messages to her brain. When she shifts from hand to hand as she travels underneath the monkey bars, she is developing upper-body strength. Hermit Crab—Place a large bag of rice or beans on the child’s back and let her move around with a heavy “shell” on her back. Joint Squeeze—Put one hand on the child’s forearm and the other on his upper arm; slowly press toward and away from his elbow. Repeat at his knee and shoulder. Press down on his head. Straighten and bend his fingers, wrists, elbows, knees, ankles, and toes. These extension and flexion techniques provide traction and compression to his joints and are effective when he’s stuck in tight spaces, such as church pews, movie theaters, cars, trains, and especially airplanes where the air pressure changes. Body Squeeze—Sit on the floor behind your child, straddling him with your legs. Put your arms around his knees, draw them toward his chest, and squeeze hard. Holding tight, rock him forward and back.

Activities to Develop the Auditory System Simplify your language. Speak slowly, shorten your comments, abbreviate instructions, and repeat what you have said. Reinforce verbal messages with gestural communication: facial expressions, hand movements, and body language. Talk to your child while she dresses, eats, or bathes, to teach her words and concepts, such as nouns (sunglasses, casserole), body parts (thumb, buttocks), prepositions (around, through), adjectives (juicy, soapy), time (yesterday, later), categories (vegetables/fruits), actions (zip, scrub), and emotions (pleased, sorry). Share your own thoughts. Model good speech and communication skills. Even if the child has trouble responding verbally, she may understand what you say. Take the time to let your child respond to your words and express his thoughts. Don’t interrupt, rush, or pressure him to talk. Be an active listener. Pay attention. Look your child in the eye when she speaks. Show her that her thoughts interest you. Help your child communicate more clearly. If you catch one word, say, “Tell me more about the truck.” If you can’t catch his meaning, have him show you by gesturing. Reward her comments with smiles, hugs, and verbal praise, such as, “That’s a great idea!” Your positive feedback will encourage her to strive to communicate. (Don’t say, “Good talking,” which means little to the child and implies that all you care about is words, rather than the message the child is trying to get across.) Use rhythm and beat to improve the child’s memory. Give directions or teach facts with a “piggyback song,” substituting your words to a familiar tune. Example: To the tune of “Mary Had a Little Lamb,” sing, “Now it’s time to wash your face, Brush your teeth, comb your hair, Now it’s time to put on clothes, So start with underwear!” Encourage your child to pantomime while listening to stories and poems, or to music without words. Read to your child every day!

Eggbeater Fun—Give your child an eggbeater to whip up soapsuds or mix up a bowl of birdseed, or of uncooked beans and rice. Marble Painting—Line a tray or cookie sheet with paper. Put a few dabs of finger paint in the center of the paper. Provide a marble to roll through the paint to make a design. Great wrapping paper! Ribbon Dancing—Attach ribbons, streamers, or scarves to the ends of a dowel. Holding the dowel with both hands, the child swirls the ribbons overhead, from side to side, and up and down. (No dowel? Give him a ribbon for each hand.) This activity also improves visual-motor coordination. Two-Sided Activities—Encourage the child to jump rope, swim, bike, hike, row, paddle, and do morning calisthenics.

The immediate causes of feelings include (a) the background flow of life processes in our organisms, which are experienced as spontaneous or homeostatic feelings; (b) the emotive responses triggered by processing myriad sensory stimuli such as tastes, smells, tactile, auditory, and visual stimuli, the experience of which is one of the sources of qualia; and (c) the emotive responses resulting from engaging drives (such as hunger or thirst) or motivations (such as lust and play) or emotions, in the more conventional sense of the term, which are action programs activated by confrontation with numerous and sometimes complex situations; examples of emotions include joy, sadness, fear, anger, envy, jealousy, contempt, compassion, and admiration.

When Ruth looked at the scans of her normal subjects, she found activation of DSN regions that previous researchers had described. I like to call this the Mohawk of self-awareness, the midline structures of the brain, starting out right above our eyes, running through the center of the brain all the way to the back. All these midline structures are involved in our sense of self. The largest bright region at the back of the brain is the posterior cingulate, which gives us a physical sense of where we are—our internal GPS. It is strongly connected to the medial prefrontal cortex (MPFC), the watchtower I discussed in chapter 4. (This connection doesn’t show up on the scan because the fMRI can’t measure it.) It is also connected with brain areas that register sensations coming from the rest of the body: the insula, which relays messages from the viscera to the emotional centers; the parietal lobes, which integrate sensory information; and the anterior cingulate, which coordinates emotions and thinking.

In retrospect, if our training had been geared to account for Body Alarm Reaction, we would have probably received less physical damage from our attackers. As your mind recognizes a potential threat to your well being, your body will start to react to this stress in a number of ways. One of the first reactions to potential physical harm is the secretion of large amounts of the hormone adrenaline into the bloodstream. Adrenaline is one many hormones that are “dumped” into the body during Body Alarm Reaction.9 Their functions are intended to be biologically protective. Unfortunately, the changes they produce can actually inhibit our ability to physically defend ourselves. The intent of the body’s automatic “call to arms’ is to provide the increases in strength and energy to either fight or run away from the threat. This is sometimes referred to as the “Fight-or-Flight” syndrome. It is a product of our evolution to develop mechanisms that allowed us to survive various physical threats. As the body continues down the path of automatic response the effects of the massive hormone “dump” will manifest itself in several different reactions. There will be an increase in both blood pressure and the heart rate.10 This is designed to increase the blood flow to the brain and the muscles, which will be placed under increased activity levels if you either defend yourself or run away. As blood flow increase to the brain and muscular system, they are the most important to survival at this particular moment, there is a decrease of blood flow to the digestive system, kidneys, liver, and skin. There will be an increase in the respiration rate to assimilate additional oxygen into the system. The increase of blood flow to the brain will induce a higher state of mental alertness and sensory perception. This is with the intent to aid our ability to mentally assess the situation at hand and to decrease our reaction time. It can have some negative effects like tunnel vision, auditory exclusion, and an impaired sense of time. There will be an increase in the level of extra energy in our blood with the higher amounts of cholesterol, fats, and blood sugar. In case we might be injured, our body also raises the level of platelets and blood clotting factors to help prevent hemorrhage. One other reaction, one that has serious implications for the martial artist, is that there will be a general increase in muscular tension. This aspect of Body Alarm Reaction alone has limiting effects on several martial skills. One in particular that we should recognize is that muscular tension equates to reduction of speed. So realistically, if we are in Body Alarm Reaction we can expect to be slower than when we are in a normal relaxed state. We can expect to have reduced ability to defend ourselves due to these automatic responses that are intended to provide assistance, but in actuality can greatly hinder that ability.11

In this regard, you can think of each individual slow wave of NREM sleep as a courier, able to carry packets of information between different anatomical brain centers. One benefit of these traveling deep-sleep brainwaves is a file-transfer process. Each night, the long-range brainwaves of deep sleep will move memory packets (recent experiences) from a short-term storage site, which is fragile, to a more permanent, and thus safer, long-term storage location. We therefore consider waking brainwave activity as that principally concerned with the reception of the outside sensory world, while the state of deep NREM slow-wave sleep donates a state of inward reflection—one that fosters information transfer and the distillation of memories. If wakefulness is dominated by reception, and NREM sleep by reflection,

In Silver’s model this injured filter system, which is regulated by the catecholamines, doesn’t screen out irrelevant information and sensory stimuli as efficiently as it should, thereby letting everything that registers at the desk of the reticular activating system arrive in the rooms of the frontal regions of the brain. The individual is bombarded, taking care of ten thousand guests in a hotel built for one thousand, on overload all the time, receiving messages about every minute aspect of his or her experience. It is no wonder, then, that the individual would be distractible or, as Silver would argue, inclined to withdraw from it all and shut the damned hotel down.

Animals under early domestication received shelter, a diet altered by agriculture, and protection from predators through relative confinement. This reduced their sensory needs, facilitating further domestication. As our domesticated animals settled in for a life of reduced activity and stimulation, so did humans. As people provided safer, more sedentary conditions for their livestock, they did the same for themselves. The confinement was mutual. By moving out of nature and settling onto farms, we became in a real sense just another farm animal.

Restricted, Repetitive Patterns of Behavior, Interests, or Activities: This includes stereotyped or repetitive movements, insistence on sameness, highly restricted interests, and hyper- or hyporeactivity to sensory input.

When practiced daily with intention, insight meditation allows you to spend less time in the DMN (your “wandering mind”) and more time in the CEN (your “observing mind”). When you learn to stay present and recognize cravings, aversions, and delusions, you develop insightful awareness. Worries and fears are replaced with solutions and decisions, enabling you to overcome life’s challenges with greater ease. Just like exercising helps to build a muscle, you can strengthen the CEN over time. Whenever your default mode network traps you in thoughts and cravings, turn it off and activate your CEN by simply asking yourself, “Am I at ease right now?” Observing your mind will bring peace. When you learn to become aware of your “wandering mind” and return to the present moment, you learn to harness your CEN—your “observing mind”—and build its power. Scientists have also discovered how we transition back and forth between the DMN and the CEN. The salience network is a third brain network that acts like a switch on a railway track, directing you between different mental states based on your current experience. For instance, the salience network can recognize that you have started a mundane activity, like brushing your teeth, and switch you over to the DMN so that you tune out. By acting as a “train conductor,” the salience network guides how the brain responds to incoming information, controlling its attention while conserving energy. By directing information to the appropriate brain pathway, the salience network controls mental traits like social behavior and self-awareness. It helps coordinate the balance between sensory information, emotions, and consciousness. Insight

The neural activity patterns that correspond to our surround are first concocted by sensory organs such as our eyes, our ears, or the tactile corpuscles in our skin. The sensory organs work with the central nervous system, where nuclei in regions such as the spinal cord and the brain stem assemble the signals collected by the sensory organs. Eventually, after a few more intermediate stations, the cerebral cortices receive and organize the perceptual signals. Thanks to the pioneering work of physiologists such as David Hubel and Torsten Wiesel, we know that the result of this setup is the construction of maps of objects and of their territories, in varied sensory modalities, for example, sight, hearing, touch. The maps are the basis for the images we experience in our minds.1

Emotions are not reactions to the world. You are not a passive receiver of sensory input but an active constructor of your emotions. From sensory input and past experience, your brain constructs meaning and prescribes action. If you didn’t have concepts that represent your past experience, all your sensory inputs would just be noise. You wouldn’t know what the sensations are, what caused them, nor how to behave to deal with them. With concepts, your brain makes meaning of sensation, and sometimes that meaning is an emotion.

In short, the brain is not a simple machine reacting to stimuli in the outside world. It’s structured as billions of prediction loops creating intrinsic brain activity. Visual predictions, auditory predictions, gustatory (taste) predictions, somatosensory (touch) predictions, olfactory (smell) predictions, and motor predictions travel throughout the brain, influencing and constraining each other. These predictions are held in check by sensory inputs from the outside world, which your brain may prioritize or ignore.18

Human imagination, however, involves some quasi-rational activity, for humans are not just moved by imagination’s products, but judge and form opinions about them. Human imagination is what Aristotle calls “deliberative” (bouleutik or logistik): “Imagination in the form of sense exists, as we have said [in De anima III, ii], in other animals, but deliberative imagination only in those which can reason” (De anima, III, xi, 434a 5ff.). Pure sensation is always true, enjoying something of the status which contemporary philosophers accord to what some of them call “raw feels”; but imagination can be false.31 It is therefore a more rationalizing activity than the elementary sensory receptiveness of the common sense.

If times or ages are mentioned in any activity, please take that as a guideline only. Children will learn the activity as it comes naturally to them. A thirty minute activity may take your child forty minutes. If the suggested age is four, but you have a three year old that can grasp the concepts do not let the recommendations hinder you. This information has not been provided for all activities. This is for a couple of reasons. One being that some of these activities span broader age ranges. The other is that while I find that sometimes it is useful to have an idea of where to start your child, it is better to look at your child in terms of ability and readiness rather than number of years. If times are included, they are meant for assistance in planning your day only. They are not in any way intended to be a marker for your child’s success. The activities have been divided up into the instructional areas of language, mathematics, sensory development and practical life skills. Many of these activities can serve as crossovers, allowing you to introduce multiple concepts at once. Some subjects such as cultural studies or science are included in practical life skills, since at this age that is primarily what those subjects encompass. Where applicable, additional skill areas have been included

It is pretty clear, then, that attention can control the brain’s sensory processing. But it can do something else, too, something that we only hinted at in our discussion of neuroplasticity. It is a commonplace observation that our perceptions and actions do not take place in a vacuum. Rather, they occur on a stage set that has been concocted from the furniture of our minds. If your mind has been primed with the theory of pointillism (the use of tiny dots of primary colors to generate secondary colors), then you will see a Seurat painting in a very different way than if you are ignorant of his technique. Yet the photons of light reflecting off the Seurat and impinging on your retina, there to be conveyed as electrical impulses into your visual cortex, are identical to the photons striking the retina of a less knowledgeable viewer, as well as of one whose mind is distracted. The three viewers “see” very different paintings. Information reaches the brain from the outside world, yes—but in “an ever-changing context of internal representations,” as Mike Merzenich put it. Mental states matter. Every stimulus from the world outside impinges on a consciousness that is predisposed to accept it, or to ignore it. We can therefore go further: not only do mental states matter to the physical activity of the brain, but they can contribute to the final perception even more powerfully than the stimulus itself. Neuroscientists are (sometimes reluctantly) admitting mental states into their models for a simple reason: the induction of cortical plasticity discussed in the previous chapters is no more the simple and direct product of particular cortical stimuli than the perception of the Seurat painting is unequivocally determined by the objective pattern of photons emitted from its oil colors: quite the contrary.

The will, it was becoming clear, has the power to change the brain—in OCD, in stroke, in Tourette’s, and now in depression—by activating adaptive circuitry. That a mental process alters circuits involved in these disorders offers dramatic examples of how the ways someone thinks about thoughts can effect plastic changes in the brain. Jordan Grafman, chief of cognitive neuroscience at the National Institute of Neurological Disorders and Stroke, calls this top-down plasticity, because it originates in the brain’s higher-order functions. “Bottom-up” plasticity, in contrast, is induced by changes in sensory stimuli such as the loss of input after amputation. Merzenich’s and Tallal’s work shows the power of this bottom-up plasticity to resculpt the brain. The OCD work hints at the power of top-down plasticity, the power of the mind to alter brain circuitry.

Aristotle pro- poses the existence of a proton organon (primary instrument) of the soul located in the heart. It is composed of the same substance as the stars,*33 fiery spirit (pneuma), yet it is so subtle as to approximate the condition of the soul, while still being a “material” as such so that it may have contact with the corporeal world as well. The soul transmits its vital activities to the body by means of this pneumatic organ, and the body communicates sensory information to the soul by means of the phantasmata produced by this same proton organon. Pneuma, then, was con- ceived of as an intermediary principle, halfway between the material world and the immaterial soul. It was the principle of communication between the two most fundamental ousia, soul and body.

emotions develop out of an undifferentiated affective state of excitement in which sensory activities are combined (as in synaesthesia).

way, to remain silent. To pay Attention means to pay attention to it all, to engage actively, to use all of our senses, to take in everything around us, including those things that don’t appear when they rightly should. It means asking questions and making sure we get answers. (Before I even go to buy that car or cell phone, I should ask: what are the features I care about most? And then I should be sure that I am paying attention to those features—and not to something else entirely.) It means realizing that the world is three-dimensional and multi-sensory and that, like it or not, we will be influenced by our environment, so our best bet is to take control of that influence by paying attention to everything that surrounds us

Those with SPD may:   •       Be overly sensitive to sights, sounds, movement or touch. •       Be under reactive to sights, sounds, movement or touch. •       Be easily distracted. •       Have emotional or social problems. •       May have an activity level that is unusual, i.e. too high or too low. •       May have difficulty making transitions from situation to situation. •       Lack self-control. •       Be clumsy or careless. •       Have difficulty calming down. •       Poor self-concept. •       Delays in speech or language. •       Delays in motor skills.

had just accomplished, we controlled the visual channel by the hand signals we gave, and we controlled smell and taste by giving either peas or hot dogs. Outputs are also easy to understand, especially if we consider movement as the main output of the brain. The earliest fMRI experiments had human subjects lying in the MRI and tapping their fingers for periods of thirty seconds. When the subjects tapped their fingers, activity in the part of the brain that controlled the hand was plainly visible. The central sulcus is a groove in the human brain that runs almost vertically down the outside of each hemisphere. Everything behind the central sulcus is broadly concerned with inputs and everything in front with outputs. It is a defining landmark that divides the frontal lobe in front of the groove from the parietal lobe behind. The frontal bank of the central sulcus, it’s important to note, contains the neurons that control movement of all the parts of the body. Toward the bottom of this groove, above the ear, we find neurons that control the hand and mouth, and as we move up toward the crown of the head, we find neurons that control the legs. The neurons found along the sulcus control the opposite side of the body. When you move your right hand, a portion of the left central sulcus will become active, and this can be seen easily with fMRI. In contrast, the neurons behind the central sulcus respond when the corresponding parts of the body are touched. These are the primary sensory neurons. As you move farther toward the back of the head, the functions of the neurons become multimodal, meaning they integrate the inputs from many senses. At the very back of the head, we find the primary visual area, which receives inputs from the eyes. Another obvious landmark of the human brain is the protuberance along the sides of the brain, just above the ear. This is the temporal lobe. Sitting directly next to the ear, parts of the temporal lobe are concerned with hearing. Other parts of the temporal lobe, along the inner crease next to the rest of the brain, contain structures critical for memory. With the dog brain, the first thing you notice is that, apart from being smaller, it has a lot fewer folds. The massive amount of folding in the human brain is the solution that evolved to cram more brain into a small space. If you could flatten out the brain, you would find that all the neurons are contained in a thin sheet just a few millimeters thick.

... when an experience is too strong for our current internal and external regulatory resource to manage ... [chemical changes activate to] tuck these pathways into our ... body. In this way, our ongoing lives are protected from the constant incursion of the raw pain and fear and the injured parts of ourselves are partly shielded from new injury. We might say they have been enwombed, awaiting the arrival of support. At the same time, the memories also remain malleable enough that they can be touched and awakened, which is essential for healing. However, we also remain vulnerable to them being brought into activity when support isn't available... a frowning face (man or woman), certain breathing patterns, and even sensory fragments (the color of a person's shirt or hair, the smell of alcohol on someone's breath) all have some probability of awakening the terror. The widely dispersed individual streams that make up these memories are all gathered into the neural net that formed at the time of the initial experience, and when our outer or inner world tugs on any strand, there is some probability that more of the neural net will open, bringing the rush of embodied feelings. Most often, the explicit memory does not arrive at the same time, so there is no context for the flood of sensations and emotions, which feels as if they are related to what is happening right now .... What can look like an out-of-proportion response to what is happening in the moment is exactly in proportion to what is unfolding internally. If we sense this so deeply that this knowing is viscerally available when our patients are having strong emotional experiences, we will be able to offer them acknowledgement of the validity of their experience rather than having to control or change it.

What people said about their pain tracked perfectly with the activation of several parts of the brain associated with pain, such as the anterior cingulate cortex (which plays a role in emotions, reward systems, and empathy), the thalamus (which handles sensory perception and alertness), and the insula (which is related to consciousness and perception). Those reporting less pain from the placebo effect showed less activity in key pain-related brain regions. And those who felt less of the placebo showed more. People were not imagining less pain; they were feeling it.

Arousal, activity level, and attention are self-regulation problems that frequently coexist with SPD. • Unusually high arousal and activity level: The child may be always on the go, restless, and fidgety. He may move with short and nervous gestures, play or work aimlessly, be quick-tempered and excitable, and find it impossible to stay seated.

• Inattention: Perhaps because of sensory over- or underresponsiveness, the child may have a short attention span, even for activities he enjoys. He may be highly distractible, paying attention to everything except the task at hand. He may be disorganized and forgetful. • Impulsivity: To get or avoid sensory stimulation, the child may be heedlessly energetic and impetuous. She may lack self-control and be unable to stop after starting an activity. She may pour juice until it spills, run pell-mell into people, overturn toy bins, and talk out of turn.

SOCIAL AND EMOTIONAL FUNCTIONING Another coexisting regulatory problem may be how the child feels about himself and relates to other people. • Poor adaptability: The child may resist meeting new people, trying new games or toys or tasting different foods. He may have difficulty making transitions from one situation to another. The child may seem stubborn and uncooperative when it is time to leave the house, come for dinner, get into or out of the bathtub, or change from a reading to a math activity. Minor changes in routine will readily upset this child who does not “go with the flow.” • Attachment problem: The child may have separation anxiety and be clingy and fearful when apart from one or two “significant olders.” Or, she may physically avoid her parents, teachers, and others in her circle. • Frustration: Struggling to accomplish tasks that peers do easily, the child may give up quickly. He may be a perfectionist and become upset when art projects, dramatic play, or homework assignments are not going as well as he expects. • Difficulty with friendships: The child may be hard to get along with and have problems making and keeping friends. Insisting on dictating all the rules and being the winner, the best, or the first, he may be a poor game-player. He may need to control his surrounding territory, be in the “driver’s seat,” and have trouble sharing toys. • Poor communication: The child may have difficulty verbally in the way she articulates her speech, “gets the words out,” and writes. She may have difficulty expressing her thoughts, feelings, and needs, not only through words but also nonverbally through gestures, body language, and facial expressions. • Other emotional problems: He may be inflexible, irrational, and overly sensitive to change, stress, and hurt feelings. Demanding and needy, he may seek attention in negative ways. He may be angry or panicky for no obvious reason. He may be unhappy, believing and saying that he is dumb, crazy, no good, a loser, and a failure. Low self-esteem is one of the most telling symptoms of Sensory Processing Disorder. • Academic problems: The child may have difficulty learning new skills and concepts. Although bright, the child may be perceived as an underachiever.

Outside the research laboratory, parents and teachers may notice other differences between SPD and ADHD. For instance, many children with SPD prefer the “same-old, same-old” in a familiar and predictable environment, while children with ADHD prefer novelty and diversion. Many children with SPD have poor motor coordination, while children with ADHD often shine in sports. Many children with SPD have adequate impulse control, unless bothered by sensations, while children with ADHD often have poor impulse control. Another difference is that medicine may help the child with ADHD, but medicine will not solve the problem of SPD. Therapy focusing on sensory integration and a sensory diet of purposeful activities help the child with SPD.

Regulatory Disorders SELF-REGULATION The child may have difficulty modulating (adjusting) his mood. He may be unable to “rev up,” or to calm down once aroused. He may become fussy easily. He may have difficulty with self-comforting after being hurt or upset. Delaying gratification and tolerating transitions from one activity to another may be hard. The child may perform unevenly: “with it” one day, “out of it” the next. Therapy, a “sensory diet” and nutritional supplements are some of the treatments that may help (see Chapter Nine

Autism is a neurobiological disorder. The structures of the brains of people with autism are atypical. Research is pointing to differences in overall brain size and the numbers of certain cells; to abnormalities in the cerebellum that affect motor, sensory, language, cognitive and attention functions; and to altered genes that interfere with brain development. A new “underconnectivity theory” suggests that autism interferes with efficient integration, timing, and synchronization of brain activation patterns. Autism, or the umbrella term, Autistic Spectrum Disorders (ASD), is not one thing but many. Like SPD and LD, the term autism encompasses a wide array of symptoms. In broad terms, autism is a Pervasive Developmental Disorder (PDD) that affects verbal and nonverbal communication, social interaction, imagination, and problem-solving.

In addition to this, chronically high levels of pressure upon nerve trunks is itself detrimental to their electrical activity, apart from such general circulatory complications. Some researchers have estimated that five pounds of pressure for five minutes on a nerve trunk can reduce its transmission efficiency by as much as forty per cent. In time, the results of these pressures can be the sharp ache of sciatica generated by the rotator muscles of the hip, numbness or tingling sensations in the hands from the neck muscles clamping down on the brachial plexus, chronic pains in the face and the head from pressure on the trigeminal nerve, and so on. And of course, since the nerve supply to internal organs can be similarly effected, such chronic constrictions can bring along a wide range of organ dysfunctions in its train of events as well—organ dysfunctions that can be extremely difficult to diagnose and treat because no “disease” state exists and no observable damage has been done to specific organ tissues. Indeed, the complications for circulation and neural transmission which follow in the wake of chronic muscular contraction present some of the gravest potential dangers for the health of the nervous system, and of the body as a whole. Loss of neural efficiency means a less and less vivid reception of the messages that the nerves convey, both from the sensory endings and to the motor units. And areas of the body that are not adequately irrigated stagnate precisely like the choked and swampy backwaters of a sluggish stream, creating septic situations that are ripe for discomfort, disease, and decay. Nor should we forget the facts that increasingly constricted capillaries require higher and higher blood pressure to make them function at all, and that once they either collapse from the muscles squeezing them or burst from increased blood pressure, they will be replaced with scar tissue and not by new capillaries, thus making the local loss permanent.

Because the efferent pathways lead directly to muscle cells, it is tempting to regard their activities as the cause of our motor behavior. But they are nothing of the kind until they are themselves stimulated by their numerous connections with the spinal cord and the brain (remember that an estimated fifteen thousand axons can converge upon a single terminal motor neuron). And these deeper, more central activities are in turn initiated and directed to a large degree by afferent, sensory stimulation. In bodywork, it is often problematical aberrations of motor response that we want to change, but sensory affects are our only means of doing so. We know we are doing our job when our hands feel jumpy reflexes smoothing out, high levels of tone decreasing, pliability returning to stiffened areas, range of motion increasing. These are all quantitative and qualitative shifts in motor activity. But we also must know that it is only our skilled manipulation of sensory stimulation which can accomplish these things, because it is primarily sensory associations which have conditioned the muscular patterns in the first place. Until the body feels something different, it cannot act differently. Only when contact with the world is perceived as something other than jabs and buffets can the organism respond with something other than aggression and defense.

These descending sensory pathways originate in the cortex, and their influence can either inhibit or facilitate the sensory input from any area of the body, greatly amplify or suppress altogether any given sensation. Sensory activity within the central nervous system is a Janus head, a two-way stream; signals originating in the brain have just as much to do with conscious sensation as do actual stimulations of the peripheral nerve endings. In fact, it is the descending paths which determine the sensitivity of any particular ascending pathway. The wide varieties of sexual response—among different individuals and within the same individual at different times—provide us with a clear example of this centrifugal influence upon incoming sensations: Depending upon past experiences and the present situation, the same stimulation of the genitals can produce intense ecstasy, bland and neutral sensations, or extreme discomfort. Orgasm can be immediate, or deferred indefinitely. And the imagination alone can produce constant engorgement, utter impotence, and all the degrees of arousal in between. The descending paths can color all kinds of sensory input to this degree. These pathways allow the mind to determine the active threshold for different sensory signals, and make it possible to focus attention upon a single source of input in the midst of many. It is difficult to imagine what practical use our sensory apparatus would be to us without such a mechanism. We would have no way of selecting a voice from all the other sounds around us, of locating specific objects within the swirl of visual impressions, or of retiring from our senses for contemplation and sleep. This centrifugal principle of selectivity is as vital to our appropriate responses to the world as is stimulation itself.

And yet what a potentially dangerous device, what a terrible opportunity to bury valuable, even vital sensory information beneath the fears and prejudices and suppressions of the higher brain! We absolutely must exercise constant discrimination upon the steady barrage of sensations if they are to take on any meaningful form and direct sequential activities; but what bizarre, even ghastly shapes this discrimination is free to invent. Attitudes, moods, neuroses, fixations, and avoidances of all kinds contribute to the sensitivity of the ascending sensory pathways themselves, so that minor irritations can be magnified to overwhelming proportions, pleasures can be erased or actually turned into torments, serious internal difficulties can be blotted completely out of consciousness. The principle of selectivity is crucial to organized behavior, but the possibilities for its abuse are enormous. The mind is capable of distorting incoming information to almost any degree, and it can actually construct a body image that has very little to do with the bulk of sensory data which the body is providing. These two directions of sensory transmission are both occurring all the time, and we cannot say that our idea of reality is more clearly established by one than by the other. Or, if we have to make a choice, we must admit that it is the descending, centrifugal sensory current that is the more important one: We all receive stimulation from the same external world through identical sensory devices, but it is the process of selection and interpretation which makes us respond differently, makes each of us the unique individuals that we are. In this process, discriminating mind descends into and is active in every synapse of the sensory system. The two processes of transmitting data through the nervous system and of interpreting it cannot be separated. Information is processed at each synaptic level of the afferent pathways. There is no one point along the afferent pathways or one particular level beneath the central nervous system below which activity cannot be a conscious sensation and above which it is a recognizable, defineable sensory experience. Perception has many levels, and it seems that the many separate stages are arranged in a hierarchy, with the more complex stages receiving input only after they are processed by the more elementary systems.13 And the more elementary systems are in turn facilitated or inhibited by the higher, more complex ones. The conclusions towards which these observations push us seems unequivocal. The cognitive, associational processes of the higher brain have just as much to do with our construction of physical reality—both within us and outside of us—as do our sensory devices and their specific stimulations. And remember, it is the perception of this sensory reality which initiates and directs our motor responses, our postures, and our behavior.

So it is necessary that we have a means of monitoring the tension developed by muscular activity, and equally necessary that the threshold of response for the inhibitory function of that monitor be a variable threshold that can be readily adjusted to suit many purposes, from preventing tissue damage due to overload, to providing a smooth and delicate twist of the tuning knob of a sensitive shortwave receiver. And such a marvelously adaptable tension-feedback system we do have in our Golgi tendon organs, reflex arcs which connect the sensory events in a stretching tendon directly to the motor events which control that degree of stretch, neural feed-back loops whose degree of sensory and motor stimulation may be widely altered according to our intent, our conscious training, and our unconscious habits. This ingenious device does, however, contain a singular danger, a danger unfortunately inherent in the very features of the Golgi reflex which are the cleverest, and the most indispensable to its proper function. The degree of facilitation of the feed-back loop, which sets the threshold value for the “required tension,” is controlled by descending impulses from higher brain centers down into the loop’s internuncial network in the brain stem and the spinal cord. In this way, conscious judgements and the fruits of practice are translated into precise neuromuscular values. But judgement and practice are not the only factors that can be involved in this facilitating higher brain activity. Relative levels of overall arousal, our attitudes towards our past experience, the quality of our present mood, neurotic avoidances and compulsions of all kinds, emotional associations from all quarters—any of these things can color descending messages, and do in fact cause considerable alterations in the Golgi’s threshold values. It is possible, for instance, to be so emotionally involved in an effort—either through panic or through exhilaration—that we do not even notice that our exertions have torn us internally until the excitement has receded, leaving the painful injury behind to surprise us. Or acute anxiety may drive the value of the “required tension” so high that our knuckles whiten as we grip the steering wheel, the pencil suddenly snaps in our fingers, or the glass shatters as we set it with too much force onto the table. On the other hand, timidity or the fear of being rejected can so sap us of “required tension” that it is difficult for us to produce a loud, clear knock upon a door that we tremble to enter.

These direct internuncial circuits in the spinal cord and this brainstem-directed gamma motor system create an astonishing condition in the numerous and elaborate sensory feedback loops of the spindles and the Golgis: We are consciously aware of almost none of their constant activities. Signals transmitted to the central nervous system from these two receptors operate entirely at a subconsious level, causing no sensory perception at all. Instead, they transmit tremendous amounts of information from the muscles and the tendons to 1) the motor control systems in the spinal cord [and the brain stem], and 2) the motor control systems of the cerebellum.

It is within this network of intermediary neurons, arranged end-to-end and side-by-side between our sensory nerve endings and our motor units, that all of our tone levels, reflexes, gestures, habits, tendencies, feelings, attitudes, postures, styles have their genesis. It is called the internuncial net, and it has come into its fullest flower in the human being. [Internuncios were official messengers for the Pope, taking information and bringing back responses from the various courts of Europe.) This net composes roughly ninety percent of our nervous systems, including the entire spinal cord and the brain. It is nothing less than the total activity of this internuncial net which influences the responses of the motor units. Let us recall our stiff old man who was anaesthetized for surgery. The anaesthesia had no direct effect on either sensory endings or motor units; rather, it interrupted the normal flow of signals in the internuncial network in the brain. The result was flaccid, unresponsive muscles, and a blanking out of all sensation produced by the scalpel and the probe. It is only by influencing the flow of impulses through the vast internuncial net that we can have any effect upon tone, habit, and behavior. The conditions which direct that flow into specific patterns have been evolved through the handling of particular qualities and amounts of sensory experience and the repetitions of specific appropriate motor responses. One of the readiest means we have of actually influencing—rather than just temporarily interrupting—the conditions within the net is the introduction of more and more positive sensory experience, which elicits new kinds of motor responses, and can thus form the basis for the development of new habits, new conditions, new patterns of neural flow. The complexities of the internuncial net are forbidding. The suggestion that bodywork might in some way make significant and lasting changes in its function may sound like the ravings of a necromancer turned amateur neurosurgeon. We know so very little, and would presume to do so much. And yet we do know that very simple means can produce remarkable and demonstrably repeatable results in this fantastically complicated network. Infants who do not receive adequate physical stimulation die or are dwarfed and deformed. Laboratory rats who are handled on a daily basis develop markedly stronger resistance to fatal diseases, even to the loss of vital organs. Between these two extremes is a wide spectrum of quantity and quality of touching, all of which must certainly affect the health of the organism if touch in the orphanage and in the laboratory can be proven to be so crucial.

The lower brain—including the pons and the brain stem—is primarily responsible for our “subconscious” processes, those many activities which are more complex and integrated than cord reflexes, but of which we are seldom aware. To begin with, many more sequences of simple reflexes are possible if the pons and the stem are left intact with the cord. The lower brain clearly assists the cord in fine-tuning responses, and in arranging them in the appropriate order so that they produce more integrated behavior. The complicated sequences of muscular contraction necessary for sucking and swallowing, for example, are monitored at this level. These are skills with which a human infant is born; their underlying circuits—and even more importantly, the correct sequence of operation of these circuits—is a product of early genetic development, not individual experience and learning. In general, the lower brain seems to share many of the “hard-wired” features of the spinal cord. Axons and synapses form organizational units that appear to be consistent for all individuals of the same species, and their activation produces identical, stereotyped contractions and motions. But the additional complexities of the lower brain appear to enable it to pick and choose more freely among various possible circuits, and to arrange the stereotyped responses with a lot more flexibility than is possible with the cord alone. For instance, it is in the lower brain that information from the semi-circular canals in the inner ear—the sensory organ for gravitational perceptions and balance—is coordinated with the cord’s postural reflexes. A stiff stance can be elicited from these postural reflexes by merely putting pressure on the bottoms of the feet; by adding information concerning gravity and balance to this stance, the same reflex cord circuits may be continually adjusted to compensate for shifts in equilibrium as we tilt the floor upon which the animal is standing, or as we push him this way or that. A rigid fixed posture is made more flexible and at the same time more stable, because compensating adjustments among the simple postural reflexes is now possible. The lower brain coordinates the movements of the eyes, so that they track together. It directs digestive and metabolic processes and glandular secretions, and determines the patterns of circulation by controlling arterial blood pressure. And not only does it give new coordination to separate parts, it influences the system as a whole in ways that cannot be done by the segmental arrangement of the cord.

As a sensory device, the tendon organ is a close partner to the muscle spindle in the assessment of the specific activity of every one of my alpha motor units. The anulospiral element of the spindle measures the length of a muscle’s fibers, and the speed with which that length is changing. Adding to this information, the Golgi tendon organs measure the tensions that are developed as a result of these changing lengths. The degree of distortion in the parallel zig-zag collagen bundles is a precise gauge of the force with which a muscle is actually pulling on the bone to which it is attached. Such a gauge is really necessary in order to fully and accurately assess the net amount of work force actually being delivered by a muscle, as opposed to merely knowing now much and how fast it is lengthening or shortening. I can shorten my bicep exactly the same distance at exactly the same speed, whether there is a book in my hand or not, and my spindles will register identical information in either case. It is only the differing stress placed upon the tendon organ during the gesture which announces and evaluates the added weight of the book.

As a team, then, the Golgis and the spindles produce a sensory impression that is very different in kind than the impressions of color, texture, odor, or sound produced by our more conscious sense. Instead of measuring any of these surface qualities, the muscle and tendon organs assess the pure mass of an object. Now mass is an invisible thing. We have only to contemplate the surprises offered by a tennis ball filled with lead, or a large “rock” made of styrofoam in a movie studio, to remind ourselves how easily deceived our other sense organs can be with regard to mass. Mass has nothing to do with surface qualities; it is the measure of an object’s resistance to movement, and I can have no idea of its value until I am actively engaged in moving the object. Nor are the sensory cues relating to mass at all constant with regard to the object. They vary continually, as a function of inertia, according to the speed with which I move the object, or the relative suddenness with which I attempt to change the direction of movement or stop the object. A five pound bucket “feels” much heavier if I swing it rapidly in a circle over my head—that is, I have to brace myself much more forcefully in order to resist its pull. It is the precise value of this resistance which is measured by the Golgi tendon organs, and when their information is correlated with the spindles’ measurement of the exact speed and distance of movement, I can arrive at an accurate estimate of mass, that invisible yet crucial property of all matter.

The Golgi organs themselves are multi-branched type endings of sensory axons, which are woven among the collagen fibers near the muscle cells, and which are stimulated by the straightening and recoiling of the tendon. As is the case with the muscle spindles, the stimulation of a single tendon organ is highly specific: Each particular organ is most directly affected by the lengthening and contracting of the few alpha muscle fibers which attach to the collagen bundles containing that tendon organ, so that each Golgi is responsive to the activities of only ten to fifteen alpha motor units.

The sensory axon that ends in the anulospiral receptor reaches out from its cell body located in the spinal cord. This cell body synapses with its own spinal sensory tracts which carry the spindles’ sensory information up each segment of the spinal column and finally to the brain, much like the orderly, parallel spinal tracts for the skin receptors, the joint receptors, and so on. But in addition to joining together in its own sensory stream like all other sensory nerves headed for the brain, the cell bodies of the anulospiral receptors make another interesting connection within the spinal column. They synapse directly to the body of a motor nerve as well, and to precisely the motor nerve which stimulates the skeletal muscle cells that surround the corresponding spindle. This means that the terminal motor nerve, the one which directly excites the muscle cells of the skeletal motor unit, can be excited not only by motor commands from the brain, but can also be excited by a sensory signal from the muscle spindle surrounded by the muscle cells of the same skeletal motor unit. 7-7: A simple spindle reflex arc. A single afferent nerve forms the anulospiral receptor at one end and synapses directly to a motor nerve at the other end, in the spinal column. This motor nerve in turn synapses to muscle cells in the immediate vicinity of the spindle, creating a very sensitive local feedback loop. This sensory-to-motor synapse in the spinal cord forms a reflex arc, the most direct linkage we have between local sensory events and local motor response. Activity in specific muscle cells creates a local sensory impulse which directly effects the subsequent activity of the same muscle cells. Thus the reflex arc constitutes a feedback loop which both keeps my muscles themselves constantly informed as to what they are up to, and constantly modifies their efforts. And most of this feedback takes place in the spinal cord, far below my levels of conscious awareness, and far more rapidly than I could consciously command it.

In the 1970s, UCLA psychologist Eric Holman discovered that certain sweetened substances could make rodents prefer certain foods by virtue of their presence. For instance, by adding a saccharin to either a banana- or an almond-flavored solution, he was able to make rats prefer the taste of bananas or almonds, respectively, a process known as “flavor nutrient conditioning.” In recent years that work has been picked up with humans. Maltodextrin, a glucose polymer, is imperceptible to most of us. It doesn’t taste sweet. In fact, it doesn’t taste like anything. For it to activate the sweet receptors in the brain, the body must first break it down into glucose. If we mix it into another food, we don’t realize there’s a sugar present, but we still develop a preference for that flavor. In one study, people who tasted foods with maltodextrin mixed in would reliably choose the flavor that had been associated with the polymer in subsequent tests. They had been trained to prefer one food over another by a sort of sensory trickery. Imagine dusting a child’s broccoli florets with maltodextrin and transforming a disliked vegetable into a favorite.

The level of activity in this reticular formation reflects an individual’s general state of arousal. Artificial over-stimulation of the entire area does not result in limb-flailing or the exaggeration of particular gestures; instead, it causes a stiffened tetany in all the muscles of the body simultaneously. Everything locks rigidly into place and cannot be moved until stimulation recedes. Conversely, blocking stimulation from reaching the whole area results in a general loss of muscle tone throughout the body, as in our anaesthetized patient. That is, activity in this area as a whole does not command our muscles to produce any particular gesture or assume any particular posture. Rather, general activity here provides the conditions of general muscle tone, sensory awareness, and mental alertness which will support and color whatever postures and gestures are made. The reticular formation cannot issue the command “raise right arm,” but it does help to establish the trembling tension, the calm readiness, or the sluggishness which will characterize how I raise my arm in response to a situation. To direct these general levels of arousal into particular movements requires the next level of the “old” brain, the basal ganglia—the highest level of sensory and motor organization of the gamma motor system.

Part of the interest and importance of this finding is that it shows that cognitive influences, originating here purely at the word-level, can reach down and modulate activations in the first stage of cortical processing that represents the value of sensory stimuli.

These two primary reflex arcs—the spindle and the Golgi—are the principal sensory devices which the nervous system uses for the enormously complicated task of maintaining and adjusting the appropriate levels of muscle tone throughout the body. The normal tone of a muscle is dependent upon the simple stretch reflex, through which the the sensory endings in a muscle, stimulated by even the slightest stretching of the muscle, initiate a segmental reflex increasing muscle tone.11 The muscle spindle, whose associated reflex arc tends to excite alpha motor neurons and their motor units, is complimented by the Golgi tendon organ, whose reflex arc tends to inhibit the same alpha neurons and motor units. Between the two of them, they produce a summation of excitation and inhibition on the alpha neurons which keeps the active muscle fibers within a narrow range of tensional forces—just the right amount to stand, to lift a book, to hold a glass. Now the problem of maintaining this precision is such a complex one not only because there are so many muscle cells in the body to monitor, but also because proper muscle tone must accomplish so many different things. It must be able to shift its various tensional values in the various parts of the musculature back and forth so rapidly in order to do all of my muscular tasks competently.

First of all, the tone of my muscle cells must hold my skeleton together so that it neither collapses in upon my organs nor dislocates at its joints. It is tone, just as much as it is connective tissues or bone, that is responsible for my basic structural shape and integrity. Secondly, my muscle tone must superimpose upon its own stability the steady, rhythmical expansion and contraction of respiration. Third, it must support my overall structure in one position or another—lying, sitting standing, and so on. Finally, it must be able to brace and release any part of the body in relation to the whole, and to do this with spontaneity and split-second timing, so that graceful, purposeful action may be added to my stability, my posture, and my rhythmic respiration. It is no wonder we find that such large portions of our nervous systems are so continually engaged in controlling the maintenance and adjustments of this tone. The entire system of spindle cells, with both their contractile parts and their anulospiral receptors, the Golgi tendon organs, the reflex arcs, much of the internuncial circuitry of the spinal column, and most of the oldest portion of our brains—including the reticular formation and the basal ganglia—all work together to orchestrate this complex phenomenon. We have, as it were, a brain within our brain and a muscle system within our muscle system to monitor the constantly shifting values of background tonus, to provide a stable yet flexible framework which we are free to use how we will. Nor is it a wonder that these elements and processes are normally controlled below my level of consciousness—if this were not the case, walking across the room to get a glass of water would require more diversified and minute attention than my conscious awareness could possibly muster. It is the old brain, along with the even more ancient spinal cord, that are given the bulk of this task, because they have had so many more generations in which to grapple with the problems and refine the solutions. Millions upon millions of trials and errors have resulted in genetically constant motor circuits and sensory feedback loops which handle the fundamental life-supporting jobs of muscle tone for me automatically. Firm structure, posture, respiratory rhythms, swallowing, elimination, grasping, withdrawing, tracking with the eyes—all these intact and fully functional activities and more are given to each of us as new-born infants, the legacy of the development of our ancestors.

The sensory roles of the anulospiral receptor and the tendon organ are absolutely central in this process of exerting and adjusting muscle tone. These devices establish the “feel” for length and tension, and it is this feeling which is maintained by the gamma motor system, the reflex arcs, and the alpha skeletal muscles. All of my muscle cells—both alpha and gamma—are continually felt by the mind as they work, whether most of these “feelings” ever reach my conscious awareness or not. And it is primarily these muscular feelings which supply my central nervous system with the constant information necessary to successfully combine the demands of free motion with those of basic structural stability. The sophistication required for this maintenance of structure and flexibility can be appreciated if we remember that almost any simple motion—such as raising the arm out to the side—changes either the length or the tension values in most of the body’s muscle cells. If one is to avoid tipping towards the extended arm, then the feet, the legs, the hips, the back, the neck, and the opposite arm all must participate in a new distribution of balance created by the “isolated” movement of raising the arm. The difficulties experienced by every child learning to sit, to stand erect, and to walk with an even gait attest to the complexity of the demands which these shifts in balance and tone make upon us. The entire musculature must learn to participate in the motion of any of its parts. And to do this, the entire musculature must feel its own activity, fully and in rich detail. Competent posture and movement are among the chief points of sensory self-awareness. The purpose of bodywork is to heighten and focus this awareness. It is the child’s task during this early motor training to experiment by trial and error, and to set the precise lengths and tensions—and changes in length and tension—in all his muscle fibers for these basic skills of standing and walking. This is the education of the basal ganglia and the gamma motor system, as learned reflex responses are added to our inherited ones. The lengths and rates of change of the spindle fibers are set at values which experience has confirmed to be appropriate for the movement desired, and then the sensorimotor reflex arcs of the spindles and the Golgis command the alpha motor nerves, and hence the skeletal muscles, to respond exactly to those specifications that have been established in the gamma system by previous trial and error. And this chain of events holds true not only for the actual limb being moved, but for all other parts of the musculature that must brace, or shift, or compensate in any way. In this complicated process, the child is guided primarily by sensory cues which become more consistent and more predictable with every repetition of his efforts.

As we have already learned, we don’t usually clearly perceive our soul; it does send us signs, however. At times these messages are sent through the medium of pain, which is meant to be a warning sign of what is going on within the soul. At other times, these signs arrive through enlightenment, which demonstrates that there is indeed another path. We should all take these lessons to heart, no matter where they lead us, in order to rise above the realm of sensory and bodily experience alone, and to actively pursue a more lofty direction.

Awareness of the Need Your unique retreat is more than a room in your house. It is: ​- ​A sensory deluge-free zone. ​- ​A designated area for engaging in favorite activities. ​- ​A place for sheer rest and introspection.

She opened the bathroom door and put on the RAID Device resting on top of her towel, activating the Para-RAID. The target was, of course, Shin, who was waiting in the corridor outside her private quarters. "Er, Captain…" The call was shut down wordlessly. She reconnected the Resonance and asked as soon as the call was connected: "Why did you hang up?" His response came in a disconcerted tone. "If anything, why did you Resonate now of all times?" “We were in the middle of a conversation.” "We can finish it later. At least wait until after you shower, please." Lena refused to back down. "Why can’t we do this while I’m in the shower?" "What do you mean, ‘why’…?" There was an exasperated pause between them, which Lena broke by persistently pressing him. "You were fine with it before. When you told me about the Black Sheep and the Shepherds, two years ago in the Spearhead squadron’s barracks, you, er…you were connected while you were in the shower." "Yes… But you don’t seem fine with it, so you don’t have to force yourself." That’s… Well, yes, she was quite embarrassed about this. Only their sense of hearing was being Resonated, but it gave the impression that they were face-to-face. Lena realized that this meant that her feeling of embarrassment over the situation was being directly transmitted to Shin, which left him feeling restless. And to top it off, the sounds of the running water and her breath, leaking out from the heat and the steam, as well as the sound of the water dripping from her long, satin-like hair, were also being transmitted. "But this time we can’t—Ah…" The Sensory Resonance ended again, and this time it seemed that he’d removed his RAID Device, since she couldn’t reconnect.

have done with anything, and so on—is based on different configurations of life: each type is discovered by inquiring into “the real forces that form thought.”92 What has changed between Spinoza and Nietzsche is not the close connection between thought and life but the definition of “thought” itself. It is no longer a ratio reinforcing reactive, sensory-motor forces, but an unbounded creativity from which active affections flow. When the subject reaches this essence or vocation and becomes active, it no longer organizes its affections rationally. It takes advantage of its excess to create new possibilities for life or new configurations of the body. The name for the type of thinker, who affirms life, carrying thought and life toward new possibilities, is “the artist.

The brain is usually quite capable of separating internal from external activity (that produced by sensory information), like keeping received and sent emails in separate folders. The theory is that hallucinations occur when this ability is compromised. If you’ve ever accidentally lumped all your emails together in the same folder you’ll know how confusing this can be, so imagine doing that with your brain functions. So the brain loses track of what’s internal and what’s external activity, and the brain isn’t good with such things. >> how blindfolded people struggle to tell the difference between apples and potatoes when eating them. >>patients who experienced hallucinations were far more sensitive to self-tickling, suggesting a compromised ability to separate internal and external stimuli. >>You walk along the street and a bus stops alongside you. This isn’t surprising because your mental model of the world recognises and knows how buses operate; you know buses stop to let passengers on and off, so you ignore this occurrence. However, if a bus pulls up outside your house and doesn’t move, this would be atypical. Your brain is now has new, unfamiliar information, and it needs to make sense of it in order to update and maintain the mental model of the world. So you investigate, and it turns out the bus has broken down. But, before you discover this, a number of other theories will have occurred to you. The bus driver’s spying on you? Someone bought you a bus? Your house has been designated as a bus depot without your knowledge? The brain comes up with all these explanations, but recognises them as very unlikely, based on the existing mental model of how things work, so they’re dismissed. Delusions result when this system undergoes alteration. A well-known type of delusion is Capgras delusion, where people genuinely believe someone close to them (spouse, parent, sibling, friend, pet) has been replaced by an identical impostor.31 Usually when you see a loved one, this triggers multiple memories and emotions: love, affection, fondness, frustration, irritation (depending on length of relationship). But suppose you see your partner and experience none of the usual emotional associations? Damage to areas of the frontal lobes can cause this to happen. Based on all your memories and experiences, your brain anticipates a strong emotional response to the sight of your partner, but this doesn’t happen. This results in uncertainty: that’s my long-term partner, I have many feelings about my long-term partner, feelings I’m now not experiencing. Why not? One way to resolve this inconsistency is the conclusion that they aren’t your partner, but a physically identical impostor. This conclusion allows the brain to reconcile the disharmony it’s experiencing, thus ending uncertainty. This is Capgras delusion.

In health, the brain gives out a steady rhythmic discharge; in disease this varies. The emotional disturbance caused by anxiety is accompanied by excessive electrical activity of nerve cells at the base of the brain, which interferes with the rhythm of the discharge of the higher centers. (Diagram 16) The electrical flow from the brain is the life of the organism and it is the medium through which all sensory reports

All in all, we are well attuned to use multiple streams of sensory data to detect whether others are sick, with or without our subjective awareness. Crucially, we are motivated to avoid the sick, too. Studies have clearly shown that viewing images of sick humans evokes intense feelings of disgust and changes our body’s physiology by both raising body temperature and priming an immune response.16 Simply seeing someone exhibiting sickness behaviour can activate your defence system, changing immunity and behaviour. Reflecting back on my typhoid vaccine experiment, it’s clear that illness avoidance was also at play. What I failed to mention earlier was that my lack of desire to give my wife a morning hug was strongly reciprocated: ‘you look gross’ are the words she used. When our immune system kicks into gear in the face of an infectious threat, it’s almost as if we become magnetized: drawn towards focusing on our inner selves and repelling others. But others also pick up on what is going on, and are repelled from us. Avoidance goes both ways.

I understand now, sir, why saints call the Lord unfathomable. Even everlasting life could not suffice to appraise Him." "That is true; but He is also near and dear. After the mind has been cleared by Kriya Yoga of sensory obstacles, meditation furnishes a twofold proof of God. Ever-new joy is evidence of His existence, convincing to our very atoms. Also, in meditation one finds His instant guidance, His adequate response to every difficulty." "I see, Guruji; you have solved my problem." I smiled gratefully. "I do realize now that I have found God, for whenever the joy of meditation has returned subconsciously during my active hours, I have been subtly directed to adopt the right course in everything, even details." "Human life is beset with sorrow until we know how to tune in with the Divine Will, whose 'right course' is often baffling to the egoistic intelligence. God bears the burden of the cosmos; He alone can give unerring counsel.

Here is another way of putting an aspect of that same parallel: just as The Critique of Pure Reason seeks to show us that the formal conditions of sensory consciousness of an object presuppose a form of synthesis that belongs to the understanding, so, too, the Tractatus seeks to show us that the formal conditions of sensory consciousness of the identity of a sign presupposes linguistic self-consciousness of the logical nexus of the symbol. Just as Kant seeks to show how, on the one hand, the understanding must bear on sensibility in order to have content (for it to represent anything), and how, on the other, the sensible manifold requires conferral of unity through the activity of the understanding to be more than merely blind (for it to amount to more than mere sensory noise); so, too, later Wittgenstein aims to show how, on the one hand, the symbol must find expression in the sign to be more than nothing (for it to say anything), and how, on the other, the form of the sign (in spoken language—its phonological form) presupposes the apprehension of its real possibilities for symbolizing (its logico-grammatical uses in acts of speech) in order for it to come into view as having the form that it does.

And since it’s been a few years,” she continued, “I did some research. Every expert—and by every expert, yes, I mean Dr. Internet—says that movement, multi-sensory activity, and hands-on learning is far better than trying to beat it into her.” “I’ve heard that, too, but there’s no movement when she takes the test to determine if she can go to third grade or not.” “Crista, listen. She’s going to learn best when the pressure is off. When it’s fun. When it’s woven into her everyday life. If we force it, she’s just going to shut down. I honestly know that from experience. And that kid?” Tessa laughed. “Little Figsworth is a breath of fresh air I didn’t know

The supplementation (e.g., when we believe we see the movement of a bird as movement), the immediate poetic completion already begins with sensory perception. We always formulate complete humans from that which we see and know of them. We do not tolerate the void — this is the impertinence of our imagination: how little is it bound and accustomed to truth! We do not content ourselves for a moment with the known (or knowable!). The playful processing of the material is our ceaseless basic activity, thus exercise of the imagination. One may consider as proof for how powerful this activity is the play of the optic nerve when the eye is closed. We read and listen in the same way. Precise listening and seeing is a very high level of culture — we are still far from it. As yet we do not feel the lying in it at all! This spontaneous play of fantasizing force is the basic life of our mind: the thoughts appear to us; whereas becoming aware, the reflection of the process in the process is only the relative exception — perhaps a refraction at the contrast.

Understanding Autistic Burnout One particularly important condition to understand is autistic burnout—a state of emotional, physical, and mental exhaustion that results from constantly pushing yourself to function in a neurotypical world. While it can look like depression on the surface, it stems from different causes and requires a different approach. Common signs of autistic burnout include: Persistent fatigue (mental or physical) Emotional flatness or sense of emptiness Difficulty regulating emotions Irritability, sadness, or frustration Loss of interest in things you once enjoyed Reduced tolerance for socializing Trouble communicating verbally Difficulty masking Trouble concentrating Heightened sensory sensitivity Recognizing these signs early is crucial. The first step toward recovery is often rest—but rest isn’t always accessible. Life obligations like work, parenting, or financial strain can delay healing. That’s why identifying what’s triggering your distress is key. These triggers may be sensory, emotional, or tied to sudden changes in routine. Managing burnout starts with awareness. Once you identify the sources of overwhelm, you can begin building a toolkit of support strategies. Recommended strategies include: Mindfulness and deep breathing Yoga or gentle movement Meditation Regular physical activity Intentional rest Supportive routines and boundaries

A major way that threats change arousal is via outputs of the CeA to neuromodulatory systems (Figure 8.7).73 (By the way, the amygdala also processes appetitive stimuli and the CeA also activates neuromodulatory systems in their presence74). The consequence of CeA activation of neuromodulatory systems is an increase in attention and vigilance, which may be achieved by lowering the threshold to detect sensory stimuli.

STIMMING Stimming, which is short for self-stimulation, is a technique that can help Autistic people manage overwhelming emotions and deal with difficult or stressful situations. Stimming can involve: Fiddling with the hands and fingers or with objects such as erasers, pencils, or paper Repetitive body movements like rocking, banging the head, or swinging Seeking visual stimulation Chewing items or one’s fingers or nails Listening to the same music or sound over and over Scratching or rubbing the skin Flapping the arms Twirling Smelling or sniffing things Bouncing Tapping things or objects repeatedly Flicking the fingers Hand flapping The triggers that may lead your child to stim can vary. They can range from being physically uncomfortable to experiencing sensory overload, strong emotions, or boredom. Some children are triggered by objects, activities, or sensations they enjoy immensely. They may use stimming to engage with these things or experiences.

What sounds good to a child is rarely the same as what looks good to a child. This is why our rote suggestions of activities—Why don’t you play outside? Why don’t you try your new drawing book? Why don’t you play cards?—never truly motivate. Boredom is a sensory feeling that calls for a sensory response. Consider: if you were hungry, which option would you prefer? A friend saying, “Why don’t you make pot roast?” Or a friend placing a fresh-from-the-dutch-oven pot roast right in front of you to eat? Boredom is the same way: we can suggest a hundred different meals, but until we actually eat, we’re still hungry.

[O]ur brains try to predict the patterns that serve our needs and that fit our action repertoires. This may well result in the use of simple models whose power resides precisely in their failing to encode every detail and nuance present in the sensory array. This is not a barrier to true contact with the world - rather, it's a prerequisite for it. For knowing the world, in the only sense that can matter to an evolved organism, means being able to act in that world: being able to respond quickly and efficiently to salient environmental opportunities.
