Brain Complexity Quotes

The human brain is a complex organ with the wonderful power of enabling man to find reasons for continuing to believe whatever it is that he wants to believe.

If you're going to decipher a hidden code from a complex set of different mazes, I'm pretty sure you need a girl's brain running the show.

It’s true that AI can mimic the human brain, but it can also outperform us mere humans by discovering complex patterns that no human being could ever process and identify.

God has given us more than fourteen billion cells and connections in our brain. Why would God give us such a complex organ system unless he expects us to use it?

If our brains were simple enough for us to understand them, we'd be so simple that we couldn't.

What mazes there are in this world. The branches of trees, the filigree of roots, the matrix of crystals, the streets her father recreated in his models... None more complicated than the human brain, Etienne would say, what may be the most complex object in existence; one wet kilogram within which spin universes.

Having the entire world's resources right at your computer yet not using them is like having a body without a brain.

Beneath the surface of the protective parts of trauma survivors there exists an undamaged essence, a Self that is confident, curious, and calm, a Self that has been sheltered from destruction by the various protectors that have emerged in their efforts to ensure survival. Once those protectors trust that it is safe to separate, the Self will spontaneously emerge, and the parts can be enlisted in the healing process

The brain weighs only three pounds, yet it is the most complex object in the solar system.

Perhaps consciousness arises when the brain's simulation of the world becomes so complex that it must include a model of itself.

The brain does not create consciousness, but conciousness created the brain, the most complex physical form on earth, for its expression.

If you don't understand how something works, never mind: just give up and say God did it. You don't know how the nerve impulse works? Good! You don't understand how memories are laid down in the brain? Excellent! Is photosynthesis a bafflingly complex process? Wonderful! Please don't go to work on the problem, just give up, and appeal to God.

Ever and again, our mind may become befuddled when we have to find out what is heads or tails. Ever and again, bewilderment may strike our brain when we have to interpret the contrasts between the dark and the bright sides of things when we have got to read complex cases and assess the divergences between the iridescent outward appearances and the grisly undercurrents of particular characters. (‘"Côté cour…Côté jardin" )

Evolution has no foresight. Complex machinery develops its own agendas. Brains — cheat. Feedback loops evolve to promote stable heartbeats and then stumble upon the temptation of rhythm and music. The rush evoked by fractal imagery, the algorithms used for habitat selection, metastasize into art. Thrills that once had to be earned in increments of fitness can now be had from pointless introspection. Aesthetics rise unbidden from a trillion dopamine receptors, and the system moves beyond modeling the organism. It begins to model the very process of modeling. It consumes evermore computational resources, bogs itself down with endless recursion and irrelevant simulations. Like the parasitic DNA that accretes in every natural genome, it persists and proliferates and produces nothing but itself. Metaprocesses bloom like cancer, and awaken, and call themselves I.

The brain is heavily influenced by genes. But from birth through young adulthood, the part of the human brain that most defines us (frontal cortex) is less a product of the genes with which you started life than of what life has thrown at you. Because it is the last to mature, by definition the frontal cortex is the brain region least constrained by genes and most sculpted by experience. This must be so, to be the supremely complex social species that we are. Ironically, it seems that the genetic program of human brain development has evolved to, as much as possible, free the frontal cortex from genes.

The mind is an incredibly complex machine, Stuart. Nobody fully understands the workings of it. Everyone has their own perception of the lives they lead and the environment in which they live them. For most of us, the perceptions are complimentary, so we accept reality as a collective experience. For instance, who is to say you see the colour of this t-shirt in the same way I do. We both perceive it as green, but whether or not we see the same colour, we can’t say. It doesn’t matter though as long as we all agree. Nevertheless, if a person comes in and says my t-shirt is red and everyone else says it is green then we have to question his or her perception of my t-shirt. There has to be a reason why their perception is different to ours. Of course, in that case, we would suspect colour blindness, a condition in which the receptors in the eye send erroneous signals to the brain. For whatever reason, Stuart, we are all seeing green, but you see red. We need to find out what is causing your brain to do that.

...when the brain is released from the constraints of reality, it can generate any sound, image, or smell in its repertoire, sometimes in complex and "impossible" combinations".

Reading fiction is important. It is a vital means of imagining a life other than our own, which in turn makes us more empathetic beings. Following complex story lines stretches our brains beyond the 140 characters of sound-bite thinking, and staying within the world of a novel gives us the ability to be quiet and alone, two skills that are disappearing faster than the polar icecaps.

But will I always love her? Does my love for her reside in my head or my heart? The scientist in her believed that emotion resulted from complex limbic brain circuitry that was for her, at this very moment, trapped in the trenches of a battle in which there would be no survivors. The mother in her believed that the love she hadd for her daughter was safe from the mayhem in her mind, because it lived in her heart.

The first language humans had was gestures. There was nothing primitive about this language that flowed from people’s hands, nothing we say now that could not be said in the endless array of movements possible with the fine bones of the fingers and wrists. The gestures were complex and subtle, involving a delicacy of motion that has since been lost completely. During the Age of Silence, people communicated more, not less. Basic survival demanded that the hands were almost never still, and so it was only during sleep (and sometimes not even then) that people were not saying something or other. No distinction was made between the gestures of language and the gestures of life. The labor of building a house, say, or preparing a meal was no less an expression than making the sign for I love you or I feel serious. When a hand was used to shield one’s face when frightened by a loud noise something was being said, and when fingers were used to pick up what someone else had dropped something was being said; and even when the hands were at rest, that, too, was saying something. Naturally, there were misunderstandings. There were times when a finger might have been lifted to scratch a nose, and if casual eye contact was made with one’s lover just then, the lover might accidentally take it to be the gesture, not at all dissimilar, for Now I realize I was wrong to love you. These mistakes were heartbreaking. And yet, because people knew how easily they could happen, because they didn’t go round with the illusion that they understood perfectly the things other people said, they were used to interrupting each other to ask if they’d understood correctly. Sometimes these misunderstandings were even desirable, since they gave people a reason to say, Forgive me, I was only scratching my nose. Of course I know I’ve always been right to love you. Because of the frequency of these mistakes, over time the gesture for asking forgiveness evolved into the simplest form. Just to open your palm was to say: Forgive me." "If at large gatherings or parties, or around people with whom you feel distant, your hands sometimes hang awkwardly at the ends of your arms – if you find yourself at a loss for what to do with them, overcome with sadness that comes when you recognize the foreignness of your own body – it’s because your hands remember a time when the division between mind and body, brain and heart, what’s inside and what’s outside, was so much less. It’s not that we’ve forgotten the language of gestures entirely. The habit of moving our hands while we speak is left over from it. Clapping, pointing, giving the thumbs-up, for example, is a way to remember how it feels to say nothing together. And at night, when it’s too dark to see, we find it necessary to gesture on each other’s bodies to make ourselves understood.

I hope that you will listen, but not with the memory of what you already know; and this is very difficult to do. You listen to something, and your mind immediately reacts with its knowledge, its conclusions, its opinions, its past memories. It listens, inquiring for a future understanding. Just observe yourself, how you are listening, and you will see that this is what is taking place. Either you are listening with a conclusion, with knowledge, with certain memories, experiences, or you want an answer, and you are impatient. You want to know what it is all about, what life is all about, the extraordinary complexity of life. You are not actually listening at all. You can only listen when the mind is quiet, when the mind doesn't react immediately, when there is an interval between your reaction and what is being said. Then, in that interval there is a quietness, there is a silence in which alone there is a comprehension which is not intellectual understanding. If there is a gap between what is said and your own reaction to what is said, in that interval, whether you prolong it indefinitely, for a long period or for a few seconds - in that interval, if you observe, there comes clarity. It is the interval that is the new brain. The immediate reaction is the old brain, and the old brain functions in its own traditional, accepted, reactionary, animalistic sense. When there is an abeyance of that, when the reaction is suspended, when there is an interval, then you will find that the new brain acts, and it is only the new brain that can understand, not the old brain

For our physiology to calm down, heal, and grow we need a visceral feeling of safety. No doctor can write a prescription for friendship and love: These are complex and hard-earned capacities. You don't need a history of trauma to feel self-conscious and even panicked at a party with strangers – but trauma can turn the whole world into a gathering of aliens.

Having the entire world's resources right at your computer yet not using them is like having a body without a brain.

None more complicated than the human brain, Etienne would say, what may be the most complex object in existence; one wet kilogram within which spin universes.

Unfortunately, little darlings, there is no such thing as a simple love story.The most transitory puppy crush is complex to the extent of lying beyond the far reaches of the brain's understanding.

We are the one creature to whom natural selection has bequeathed a brain complex enough to comprehend the laws that govern the universe. And we should be proud that we are the only species that has figured how we came to be.

We're not hunter-gatherers anymore. We're all living like patients in the intensive care unit of a hospital. What keeps us alive isn't bravery, or athleticism, or any of those other skills that were valuable in a caveman society. It's our ability to master complex technological skills. It is our ability to be nerds. We need to breed nerds.

Compared to the complexity of the universe, this world of ours is like the brain of a worm.

The complex human eye harvests light. It perceives seven to ten million colors through a synaptic flash: one-tenth of a second from retina to brain. Homo sapiens gangs up to 70 percent of its sense receptors solely for vision, to anticipate danger and recognize reward, but also—more so—for beauty.

As modern-day neuroscience tells us, we are never in touch with the present, because neural information-processing itself takes time. Signals take time to travel from your sensory organs along the multiple neuronal pathways in your body to your brain, and they take time to be processed and transformed into objects, scenes, and complex situations. So, strictly speaking, what you are experiencing as the present moment is actually the past.

My father did not become the bad guy for me. Not yet. That day I hated my mother for killing my father, but also for all the reasons you cannot say. Part of my child brain hated her because she wasn’t young enough or even beautiful enough. Because she wasn’t strong enough. Or because she was too strong. Because she was so complex where my father was not. I hated my mother, in short, for being a woman.

Generally the rational brain can override the emotional brain, as long as our fears don’t hijack us. (For example, your fear at being flagged down by the police can turn instantly to gratitude when the cop warns you that there’s an accident ahead.) But the moment we feel trapped, enraged, or rejected, we are vulnerable to activating old maps and to follow their directions. Change begins when we learn to "own" our emotional brains. That means learning to observe and tolerate the heartbreaking and gut-wrenching sensations that register misery and humiliation. Only after learning to bear what is going on inside can we start to befriend, rather than obliterate, the emotions that keep our maps fixed and immutable.

The truth is that play seems to be one of the most advanced methods nature has invented to allow a complex brain to create itself.

Faith is unlearning this senseless worries and misguided beliefs that keep us captive. It is far more complex than simply modifying behavior. Faith is rewiring the human brain. We are literally upgrading our minds by downloading the mind of Christ.

We are part of nature, a product of a long evolutionary journey. To some degree, we carry the ancient oceans in our blood. … Our brains and nervous systems did not suddenly spring into existence without long antecedents in natural history. That which we most prize as integral to our humanity - our extraordinary capacity to think on complex conceptual levels - can be traced back to the nerve network of primitive invertebrates, the ganglia of a mollusk, the spinal cord of a fish, the brain of an amphibian, and the cerebral cortex of a primate.

Eighty two percent of the traumatized children seen in the National Child Traumatic Stress Network do not meet diagnostic criteria for PTSD.15 Because they often are shut down, suspicious, or aggressive they now receive pseudoscientific diagnoses such as “oppositional defiant disorder,” meaning “This kid hates my guts and won’t do anything I tell him to do,” or “disruptive mood dysregulation disorder,” meaning he has temper tantrums. Having as many problems as they do, these kids accumulate numerous diagnoses over time. Before they reach their twenties, many patients have been given four, five, six, or more of these impressive but meaningless labels. If they receive treatment at all, they get whatever is being promulgated as the method of management du jour: medications, behavioral modification, or exposure therapy. These rarely work and often cause more damage.

Our surmises regarding the subtle functions of neural processes within the brain are profoundly constrained by the fact that the brain did not evolve in order to understand itself. The complex organization of the brain evolved as a consequence of our sensorial and muscled engagement with the landscapes that surround us.

A powerful AI system tasked with ensuring your safety might imprison you at home. If you asked for happiness, it might hook you up to a life support and ceaselessly stimulate your brain's pleasure centers. If you don't provide the AI with a very big library of preferred behaviors or an ironclad means for it to deduce what behavior you prefer, you'll be stuck with whatever it comes up with. And since it's a highly complex system, you may never understand it well enough to make sure you've got it right.

Art is the result of facing almost no survival pressure at all. It’s the product of leisure time. Our big brains, the most complex instruments known in the universe, have been released from the vigilance of evading predators and seeking sustenance, permitting our imagination to gambol and explore, to dream while awake, to share visions of God. Art signals our freedom. It exists because we’ve won the evolutionary war.

Cephalopods are an island of mental complexity in the sea of invertebrate animals. Because our most recent common ancestor was so simple and lies so far back, cephalopods are an independent experiment in the evolution of large brains and complex behavior. If we can make contact with cephalopods as sentient beings, it is not because of a shared history, not because of kinship, but because evolution built minds twice over.

And now all those brain cells are dead – and my mother – who in a sense was the complex electrochemical interaction of all these millions of neurons – is no more. In neuroscience it is called ‘the binding problem’ – the extraordinary fact, which nobody can even begin to explain, that mere brute matter can give rise to consciousness and sensation. I had such a strong sensation, as she lay dying, that some deeper, ‘real’ person was still there behind the death mask.

It is remarkable that mind enters into our awareness of nature on two separate levels. At the highest level, the level of human consciousness, our minds are somehow directly aware of the complicated flow of electrical and chemical patterns in our brains. At the lowest level, the level of single atoms and electrons, the mind of an observer is again involved in the description of events. Between lies the level of molecular biology, where mechanical models are adequate and mind appears to be irrelevant. But I, as a physicist, cannot help suspecting that there is a logical connection between the two ways in which mind appears in my universe. I cannot help thinking that our awareness of our own brains has something to do with the process which we call "observation" in atomic physics. That is to say, I think our consciousness is not just a passive epiphenomenon carried along by the chemical events in our brains, but is an active agent forcing the molecular complexes to make choices between one quantum state and another. In other words, mind is already inherent in every electron, and the processes of human consciousness differ only in degree but not in kind from the processes of choice between quantum states which we call "chance" when they are made by electrons.

The neurons that do expire are the ones that made imitation possible. When you are capable of skillful imitation, the sweep of choices before you is too large; but when your brain loses its spare capacity, and along with it some agility, some joy in winging it, and the ambition to do things that don't suit it, then you finally have to settle down to do well the few things that your brain really can do well--the rest no longer seems pressing and distracting, because it is now permanently out of reach. The feeling that you are stupider than you were is what finally interests you in the really complex subjects of life: in change, in experience, in the ways other people have adjusted to disappointment and narrowed ability. You realize that you are no prodigy, your shoulders relax, and you begin to look around you, seeing local color unrivaled by blue glows of algebra and abstraction.

I suspect that 'Kindness and Cruelty' and 'Mercy and Justice' all have secret affairs, as though they rendezvous only within certain sophisticated souls: those who hate being offensive, but love telling the truth.

Psychiatry, as a subspecialty of medicine, aspires to define mental illness as precisely as, let’s say, cancer of the pancreas, or streptococcal infection of the lungs. However, given the complexity of mind, brain, and human attachment systems, we have not come even close to achieving that sort of precision. Understanding what is “wrong” with people currently is more a question of the mind-set of the practitioner (and of what insurance companies will pay for) than of verifiable, objective facts.

Chaos doesn’t mean that the system is behaving randomly, it means that it is unpredictable because it has many variables, it is too complex to measure, and even if it could be measured, theoretically the measurement cannot be done accurately and the tiniest inaccuracy would change the end result an enormous amount.

Huxley: "Tell me something Bryce, do you know the difference between a Jersey, a Guernsey, a Holstein, and an Ayershire?" Bryce: "No." Huxley: "Seabags Brown does." Bryce: "I don't see what that has to do..." Huxley: "What do you know about Gaelic history?" Bryce: "Not much." Huxley: "Then why don't you sit down one day with Gunner McQuade. He is an expert. Speaks the language, too." Bryce: "I don't..." Huxley: " What do you know about astronomy?" Bryce: "A little." Huxley: "Discuss it with Wellman, he held a fellowship." Bryce: "This is most puzzling." Huxley: "What about Homer, ever read Homer?" Bryce: "Of course I've read Homer." Huxley: "In the original Greek?" Bryce: "No" Huxley: "Then chat with Pfc. Hodgkiss. Loves to read the ancient Greek." Bryce: "Would you kindly get to the point?" Huxley: "The point is this, Bryce. What makes you think you are so goddam superior? Who gave you the bright idea that you had a corner on the world's knowledge? There are privates in this battalion who can piss more brains down a slit trench then you'll ever have. You're the most pretentious, egotistical individual I've ever encountered. Your superiority complex reeks. I've seen the way you treat men, like a big strutting peacock. Why, you've had them do everything but wipe your ass.

Man is not a 'fixed and limited animal whose nature is absolutely constant'. He changed drastically when he developed 'divided consciousness' to cope with complexities of civilisation, and has been changing steadily ever since. His greatest problem, the problem that has caused most of his agonies and miseries, has been his attempt to compensate for the narrowing of cinsciousness and the entrapment in the left-brain ego. His favorite method of compensation has been to seek out excitement. He feels most free in moments of conquest; so for the past three thousand years or so, most of the greatest man have led armies into their neighbours' territority, and turned order into chaos. This has plainly been a retrogressive step; the evolutionary urge has been defeating its own purpose.

Their manipulation is psychological and emotionally devastating – and very dangerous, especially considering the brain circuitry for emotional and physical pain are one and the same (Kross, 2011). What a victim feels when they are punched in the stomach can be similar to the pain a victim feels when they are verbally and emotionally abused, and the effects of narcissistic abuse can be crippling and long-lasting, even resulting in symptoms of PTSD or Complex PTSD.

To him, the drug released the complex brew within the brain that served up the savored past. To me, it proved that the past was living still, that we were all participants, all witnesses. I was Roger, I was Bodrugan, I was Cain; and in being so was more truly myself.

It is interesting to note that although our limbic system functions throughout our lifetime, it does not mature. As a result, when our emotional "buttons" are pushed, we retain the ability to react as though we were a two year old, even when we are adults. As our higher cortical cells mature and become integrated in complex networks with other neurons, we gain the ability to take "new pictures" of the present moment. When we compare the new information of our thinking mind with the automatic reactivity of our limbic mind, we can reevaluate the current situation and purposely choose a more mature response.

The brain represented the most complex organism ever to exist, and impossible to tame. Morality could not be spawned by tweaking a few genes or shutting off a few neurons. Not yet. So though humanity conquered the very stars, it remained unable to conquer the darkness within.

A few years ago I heard Jerome Kagan, a distinguished emeritus professor of child psychology at Harvard, say to the Dalai Lama that for every act of cruelty in this world there are hundreds of small acts of kindness and connection. His conclusion: "To be benevolent rather than malevolent is probably a true feature of our species." Being able to feel safe with other people is probably the single most important aspect of mental health; safe connections are fundamental to meaningful and satisfying lives. Numerous studies of disaster response around the globe have shown that social support is the most powerful protection against becoming overwhelmed by stress and trauma. Social support is not the same as merely being in the presence of others. The critical issue is reciprocity: being truly heard and seen by the people around us, feeling that we are held in someone else's mind and heart. For our physiology to calm down, heal, and grow we need a visceral feeling of safety. No doctor can write a prescription for friendship and love: These are complex and hard-earned capacities. You don't need a history of trauma to feel self-conscious and even panicked at a party with strangers - but trauma can turn the whole world into a gathering of aliens.

Who knew the cure for herpes would turn all those sexual deviants into people-eating, brain-dead, infection-giving assholes? Not me. The whole phenomenon gave a girl a serious complex about safe sex. Not that I was having sex. Or would be any time soon.

Modern neuroscience solidly supports Freud’s notion that many of our conscious thoughts are complex rationalizations for the flood of instincts, reflexes, motives, and deep-seated memories that emanate from the unconscious.

Prediction in a complex world is a chancy business. Every decision that a survival machine takes is a gamble, and it is the business of genes to program brains in advance so that on average they take decisions that pay off. The currency used in the casino of evolution is survival, strictly gene survival, but for many purposes individual survival is a reasonable approximation.

I would tell my staff about the “dinosaur’s tail”: As a leader grows more senior, his bulk and tail become huge, but like the brontosaurus, his brain remains modestly small. When plans are changed and the huge beast turns, its tail often thoughtlessly knocks over people and things. That the destruction was unintentional doesn’t make it any better.

For days and weeks on end one racks one's brains to no avail, and, if asked, one could not say whether one goes on writing purely out of habit, or a craving for admiration, or because one knows not how to do anything other, or out of sheer wonderment, despair or outrage, any more than one could say whether writing renders one more perceptive or more insane. Perhaps we all lose our sense of reality to the precise degree to which we are engrossed in our own work, and perhaps that is why we see in the increasing complexity of our mental constructs a means for greater understanding, even while intuitively we know that we shall never be able to fathom the imponderables that govern our course through life?

Hubert's wife, Mindy, was a tiny powerhouse of a woman with a halo of wild blond hair and eye makeup so complex it took me a while to locate her pupils. She was clearly the brains of the operation, such as she was.

Addiction to alcohol is also a neurological phenomenon, the result of a complex set of molecular alterations that take place in the brain when it’s excessively and repeatedly exposed to the drug. The science of addiction is complicated, but the basic idea is fairly straightforward: alcohol appears to wreak havoc on the brain’s natural systems of craving and reward, compromising the functioning of the various neurotransmitters and proteins that create feelings of well-being.

The books taught me that when we live through traumatic experiences, our brains take in the things around us that are causing the greatest threat, and they encode these things deep into our subconscious as sources of danger.

if your brain changes in response to experience, then you have the opportunity to deliberately help your brain change again based on new experiences you create.

Something as superfluous as "play" is also an essential feature of our consciousness. If you ask children why they like to play, they will say, "Because it's fun." But that invites the next question: What is fun? Actually, when children play, they are often trying to reenact complex human interactions in simplified form. Human society is extremely sophisticated, much too involved for the developing brains of young children, so children run simplified simulations of adult society, playing games such as doctor, cops and robber, and school. Each game is a model that allows children to experiment with a small segment of adult behavior and then run simulations into the future. (Similarly, when adults engage in play, such as a game of poker, the brain constantly creates a model of what cards the various players possess, and then projects that model into the future, using previous data about people's personality, ability to bluff, etc. The key to games like chess, cards, and gambling is the ability to simulate the future. Animals, which live largely in the present, are not as good at games as humans are, especially if they involve planning. Infant mammals do engage in a form of play, but this is more for exercise, testing one another, practicing future battles, and establishing the coming social pecking order rather than simulating the future.)

Anger is easy, Rebecca. It’s the most rudimentary of human feelings. Babies experience anger. Psychopaths experience anger. People with little to no brain activity experience anger. But compassion and forgiveness are challenging. They’re the most complex of all the emotions.

Brains of higher complexity can remember more. A brain doesn’t store memories like files in a computer​—​it reconstructs them on demand with electricity and swirling chemicals. We call this process remembering but it’s really assembling.

... we have created a man with not one brain but two. ... This new brain is intended to control the biological brain. ... The patient's biological brain is the peripheral terminal -- the only peripheral terminal -- for the new computer. ... And therefore the patient's biological brain, indeed his whole body, has become a terminal for the new computer. We have created a man who is one single, large, complex computer terminal. The patient is a read-out device for the new computer, and is helpless to control the readout as a TV screen is helpless to control the information presented on it.

Unrelenting criticism, especially when it is ground in with parental rage and scorn, is so injurious that it changes the structure of the child’s brain. Repeated messages of disdain are internalized and adopted by the child, who eventually repeats them over and over to himself. Incessant repetitions result in the construction of thick neural pathways of self-hate and self-disgust. Over time a self-hate response attaches to more and more of the child’s thoughts, feelings and behaviors. Eventually, any inclination toward authentic or vulnerable self-expression activates internal neural networks of self-loathing. The child is forced to exist in a crippling state of self-attack, which eventually becomes the equivalent of full-fledged self-abandonment. The ability to support himself or take his own side in any way is decimated. With ongoing parental reinforcement, these neural pathways expand into a large complex network that becomes an Inner Critic that dominates mental activity. The inner critic’s negative perspective creates many programs of self-rejecting perfectionism. At the same time, it obsesses about danger and catastrophizes incessantly.

Conscious Parenting on Children's Happiness and matrix of influences: 'We live surrounded by an increasingly complex matrix of impulses allowing strangers of all sorts (TV, media, Internet) interfere in our children’s mental, emotional and spiritual development. Understanding this intricate network and how does the human brain interacts with it is increasingly becoming our door to happiness and health.

On the other hand, mere critical thinking, without creative and intuitive insights, without the search for new patterns, is sterile and doomed. To solve complex problems in changing circumstances requires the activity of both cerebral hemispheres: the path to the future lies through the corpus callosum.

Science seeks to understand complex processes by reducing them to their essential actions and studying the interplay of those actions--and this reductionist approach extends to art as well. Indeed, my focus on one school of art, consisting of only three major representatives, is an example of this. Some people are concerned that a reductionist analysis will diminish our fascination with art, that it will trivialize art and deprive it of its special force, thereby reducing the beholder's share to an ordinary brain function. I argue to the contrary, that be encouraging a focus on one mental process at a time, reductionism can expand our vision and give us new insights into the nature and creation of art. These new insights will enable us to perceive unexpected aspects of art that derive from the relationships between the biological and psychological phenomena.

He always reminded us that every atom in our bodies was once part of a distant star that had exploded. He talked about how evolution moves from simplicity toward complexity, and how human intelligence is the highest known expression of evolution. I remember him telling me that a frog's brain is much more complex than a star. He saw human consciousness as the first neuron of the universe coming to life and awareness. A spark in the darkness, waiting to spread to fire.

Hyperarousal causes traumatized people to become easily distressed by unexpected stimuli. Their tendency to be triggered into reliving traumatic memories illustrates how their perceptions have become excessively focused on the involuntary search for the similarities between the present and their traumatic past. As a consequence, many neutral experiences become reinterpreted as being associated with the traumatic past.

Why do writers use symbolism?” Okay, so let’s say you have a headache and you wanna tell someone about it and you say, “I have a headache!” and other people are like, “Yeah, whatever. Everybody gets headaches.” But your headache is not a regular headache, it’s a serious headache, so you say, “My brain is on fire!” to try to help these people understand that this is a headache that needs attention! That’s a metaphor, right? And you use it so that you can be understood. Now let’s say you want to take those same imagistic principles but apply them to a much more complex idea than having a headache, like, for instance, the yearning that one feels for one’s dreams. And you can see the dream but you can’t cross the bay to get to the green light that embodies your dream. And you want to talk about how socio-economic class in America is a barrier – a bay-like barrier, some would say – that stands between you and the green light and makes that gap unbridgeable. Now, you can just talk about that stuff directly, but when you talk about it symbolically, it becomes more powerful, because instead of being abstract it becomes kind of observable…. So I think that’s why.

Habits are undeniably useful tools, relieving us of the need to run a complex mental operation every time we’re confronted with a new task or situation. Yet they also relieve us of the need to stay awake to the world: to attend, feel, think, and then act in a deliberate manner. (That is, from freedom rather than compulsion.) If you need to be reminded how completely mental habit blinds us to experience, just take a trip to an unfamiliar country. Suddenly you wake up! And the algorithms of everyday life all but start over, as if from scratch. This is why the various travel metaphors for the psychedelic experience are so apt. The efficiencies of the adult mind, useful as they are, blind us to the present moment. We’re constantly jumping ahead to the next thing. We approach experience much as an artificial intelligence (AI) program does, with our brains continually translating the data of the present into the terms of the past, reaching back in time for the relevant experience, and then using that to make its best guess as to how to predict and navigate the future. One of the things that commends travel, art, nature, work, and certain drugs to us is the way these experiences, at their best, block every mental path forward and back, immersing us in the flow of a present that is literally wonderful—wonder being the by-product of precisely the kind of unencumbered first sight, or virginal noticing, to which the adult brain has closed itself. (It’s so inefficient!) Alas, most of the time I inhabit a near-future tense, my psychic thermostat set to a low simmer of anticipation and, too often, worry. The good thing is I’m seldom surprised. The bad thing is I’m seldom surprised.

The things most people need to learn in therapy are related to attachment, abandonment, love, and fear. We are trying to access basic emotional processes that are organized in primitive and early-developing parts of the brain. The language of these emotions is also very basic; it is the language of childhood. The more complex the language and ideas you bring into therapy, the more likely you are to stimulate your clients’ intellectualizing defenses.

There are no inherent barriers to our being able to reverse engineer the operating principles of human intelligence and replicate these capabilities in the more powerful computational substrates that will become available in the decades ahead. The human brain is a complex hierarchy of complex systems, but it does not represent a level of complexity beyond what we are already capable of handling.

We have a tendency to become detached observers rather than participants. There might also be a sense of disassembling a complex, flowing process to focus on a small part of it. If we expand our focus to include emerging, one of the first changes we may notice is the bodily sense of being in the midst of something, of constant motion, lack of clarity (in the left-hemisphere sense), and unpredictability.

The results of the study were astoundingly clear: The more childhood trauma someone had suffered, the worse their health outcomes were in adulthood. And their risk for contracting diseases didn’t go up just a few percentage points. People with high ACE scores were about three times as likely to develop liver disease, twice as likely to develop cancer or heart disease, four times as likely to develop emphysema.[2] They were seven and a half times more likely to become alcoholics, four and a half times more likely to suffer from depression, and a whopping twelve times more likely to attempt suicide.[3] Scientists have learned that stress is literally toxic. Stress chemicals like cortisol and adrenaline surging through our bodies are healthy in moderation—you wouldn’t be able to get up in the morning without a good dose of cortisol. But in overwhelming quantities, they become toxic and can change the structure of our brains. Stress and depression wear our bodies out. And childhood trauma affects our telomeres. Telomeres are like little caps on the ends of our strands of DNA that keep them from unraveling. As we get older, those telomeres get shorter and shorter. When they’ve finally disappeared, our DNA itself begins to unravel, increasing our chances of getting cancer and making us especially susceptible to disease. Because of this tendency, telomeres are linked to human lifespan. And studies have shown that people who suffered from childhood trauma have significantly shortened telomeres.[4]

Non-verbal behaviour, language, facial expression, intonations and gestures are instrumental in establishing complex contradictory, predominantly emotional relations between people and between man and the world. How frequently a touch by the shoulder, a handshake or a look tell more than can be expressed in a long monologue. Not because our speech is not accurate enough. Just the contrary. It is precisely its accuracy and definiteness that make speech unsuited for expressing what is too complex, changeful and ambiguous.

The more we learn of the true nature of non-human animals, especially those with complex brains and corresponding complex social behavior, the more ethical concerns are raised regarding their use in the service of man -- whether this be in entertainment, as "pets," for food, in research laboratories, or any of the other uses to which we subject them.

idea that the male is the default-model human still deeply pervades our culture. The male is considered simple; the female, complex.

The problem with this premise, of course, is that whereas other children had programmers who fed their brains with love and kindness, my programmers were evil. My code is flawed.

One thing I can say with complete certainty is that it is a bad idea to trust the majority of experts in any domain in which both complexity and large amounts of money are involved.

Many of the problems facing us may be soluble, but only if we are willing to embrace brilliant, daring and complex solutions. Such solutions require brilliant, daring and complex people. I believe that there are many more of them around—in every nation, ethnic group and degree of affluence—than we realize.

In Eugenia Leigh’s poem “Gold,” she writes, “Tell me // I am not the thing / my children will have to survive. / Tell me // the mob I inherited will not touch / my son. Yes, the cavalcade / of all that’s tried to kill me // may forever raid my brain, but know / this: in my mother’s first language, / the word for fracture, for crack, / is the same as the word for gold.”[1

Perhaps you’re fascinated by the contours of my cheeks with skin like bed sheets that hide all of the complexities of what’s underneath, and present an image of simplicity (that is easier to digest than skipping heart beats for hairy legs). I wonder if these next six nights of not having to feel so alone will make you wondrous in keeping me as a bedside table: to place your hard times on before you get the forty winks your eyes need to glisten in the midday light of my bedroom. And it’s hard to fall back into sleep when I’ve fallen in love with studying the one that lies next to me. I wonder if you’ve found landscapes in my elbows like I’ve found ebbing tides in your forehead. Perhaps your love for me is fleeting, and you’ll have moments where you consider tearing yourself even further apart, but as soon as it’s possible you close your eyes again, fall out of the thought and back into sleep. But, perhaps you’ll keep me as a bedside table: to place your brain things in my cupboards, to place your step dad in my cupboards, to place your sad eyes in my drawers, to put your heart ache in my mouth, your desire for love in bite marks on my neck, and your misty breath in my ears whispering ‘you are so important to me’. -Bedside Table

And' and 'or' are the basic operations of logic. Together with 'no' (the logical operation of negation) they are a complete set of basic logical operations—all other logical operations, no matter how complex, can be obtained by suitable combinations of these.

The first lesson that the sages of the Upanishads teach their selected pupils is the inadequacy of the intellect. How can this feeble brain, that aches at a little calculus, ever hope to understand the complex immensity of which it is so transitory a fragment?

In The Story you will see that the two mice do better when they are faced with change because they keep things simple, while the two Littlepeople’s complex brains and human emotions complicate things. It is not that mice are smarter. We all know people are more intelligent than mice. However, as you watch what the four characters do, and realize both the mice and the Littlepeople represent parts of ourselves-the simple and the complex—you can see it would be to our advantage to do the simple things that work when things change. In

We fit beautifully together like this. Sex with her shattered me down to my deepest levels of complexity; even if Brynne wasn’t aware, I was. I don’t even know what I said to her during the heat of it. I say all kinds of things to her because she likes my filthy mouth. She told me so. It’s a damn good thing too because I cannot help it. The filter between my brain and my mouth is pretty much nonexistent.

Two and a half million years ago, when our distant relative Homo habilis was foraging for food across the Tanzanian savannah, a beam of light left the Andromeda Galaxy and began its journey across the Universe. As that light beam raced across space at the speed of light, generations of pre-humans and humans lived and died; whole species evolved and became extinct, until one member of that unbroken lineage, me, happened to gaze up into the sky below the constellation we call Cassiopeia and focus that beam of light onto his retina. A two-and-a-half-billion-year journey ends by creating an electrical impulse in a nerve fibre, triggering a cascade of wonder in a complex organ called the human brain that didn’t exist anywhere in the Universe when the journey began.

Anxiety is a complex emotional response that’s similar to fear. Both arise from similar brain processes and cause similar physiological and behavioral reactions; both originate in portions of the brain designed to help all animals deal with danger. Fear and anxiety differ, however, in that fear is typically associated with a clear, present, and identifiable threat, whereas anxiety occurs in the absence of immediate peril.

Every distraction imposes a cost on the depth of your focus. When your brain changes contexts—say, going from painting a picture to answering a text and then back to painting again—there’s a switching cost. Your brain has to load a different set of rules and information into working memory. This “boot up” costs at least a few minutes, and for complex tasks, it can take even longer. The two of us have found it can take a couple of hours of uninterrupted writing before we’re doing our best work; sometimes it even requires several consecutive days before we’re in the zone.

We were a bunch of primates who had gotten together and, against all odds, built a wondrous civilization. But paradoxically—tragically—our creation’s complexity had now far outstripped our brains’ ability to manage it.

... the neuro- in neurodiversity is most usefully understood as referring not just to the brain but to the entire nervous system–and, by extension, to the full complexity of human cognition and the central role the nervous system plays in the embodied dance of consciousness”(Walke2021, p. 55).

As I discussed in the previous chapter, attachment researchers have shown that our earliest caregivers don't only feed us, dress us, and comfort us when we are upset; they shape the way our rapidly growing brain perceives reality. Our interactions with our caregivers convey what is safe and what is dangerous: whom we can count on and who will let us down; what we need to do to get our needs met. This information is embodied in the warp and woof of our brain circuitry and forms the template of how we think of ourselves and the world around us. These inner maps are remarkably stable across time. This doesn‘t mean, however, that our maps can‘t be modified by experience. A deep love relationship, particularly during adolescence, when the brain once again goes through a period of exponential change, truly can transform us. So can the birth of a child, as our babies often teach us how to love. Adults who were abused or neglected as children can still learn the beauty of intimacy and mutual trust or have a deep spiritual experience that opens them to a larger universe. In contrast, previously uncontaminated childhood maps can become so distorted by an adult rape or assault that all roads are rerouted into terror or despair. These responses are not reasonable and therefore cannot be changed simply by reframing irrational beliefs.

That’s really the golden age, isn’t it? That’s what my brain is longing for, a time when I only saw the sparkle. A time when I loved this unabashedly because I hadn’t realized that the sparkle was a distraction layered over a complex concept full of cracks and mold, and the day you see beyond the glitter for the first time is the day you officially grow up, no going back.

I remember a hundred lovely lakes, and recall the fragrant breath of pine and fir and cedar and poplar trees. The trail has strung upon it, as upon a thread of silk, opalescent dawns and saffron sunsets. It has given me blessed release from care and worry and the troubled thinking of our modern day. It has been a return to the primitive and the peaceful. Whenever the pressure of our complex city life thins my blood and benumbs my brain, I seek relief in the trail; and when I hear the coyote wailing to the yellow dawn, my cares fall from me - I am happy. ~Hamlin Garland, McClure's, February 1899

Here's the plain truth, at least as it has been shown to me: We are never far from wonders. I remember when my son was about two, we were walking in the woods one November morning. We were along a ridge, looking down at a forest in the valley below, where a cold haze seemed to hug the forest floor. I kept trying to get my oblivious two-year-old to appreciate the landscape. At one point, I picked him up and pointed out toward the horizon and said, "Look at that, Henry, just look at it!" And he said, "Weaf!" I said, "What?" And again he said, "Weaf," and then reached out and grabbed a single brown oak leaf from the little tree next to us. I wanted to explain to him that you can see a brown oak leaf anywhere in the eastern United States in November, that nothing in the forest was less interesting. But after watching him look at it, I began to look as well, and I soon realized it wasn't just a brown leaf. Its veins spidered out red and orange and yellow in a pattern too complex for my brain to synthesize, and the more I looked at that leaf with Henry, the more I was compelled into an aesthetic contemplation I neither understood nor desired, face-to-face with something commensurate to my capacity for wonder. Marveling at the perfection of that leaf, I was reminded that aesthetic beauty is as much about how and whether you look as what you see. From the quark to the supernova, the wonders do not cease. It is our attentiveness that is in short supply, our ability and willingness to do the work that awe requires.

How does language interact with thought? Does language enable us to think, or does thinking enable us to talk? Can we think in a sophisticated manner without silent internal speech? And lastly, how did this extraordinarily complex, multicomponent system originally come into existence in our hominin ancestors?

Somewhere, within our brain, we have a potential for higher mathematics, complex physics, art, & amazing richness of thoughts, feelings & sensations Somewhere within our brain we have a potential to understand the Magic of Creative Thinking

As a boy, Picasso struggled with reading, writing, and arithmetic. Einstein was slow to talk and would apply picture thinking to complex problems in the field of physics. The dividing line between psychiatric disorders and great gifts is often a very narrow one and strongly depends on how someone is viewed by their surroundings.

The current technological and scientific revolution implies not that authentic individuals and authentic realities can be manipulated by algorithms and TV cameras, but rather that authenticity is a myth. People are afraid of being trapped inside a box, but they don’t realise that they are already trapped inside a box – their brain – which is locked within a bigger box – human society with its myriad fictions. When you escape the matrix the only thing you discover is a bigger matrix. When the peasants and workers revolted against the tsar in 1917, they ended up with Stalin; and when you begin to explore the manifold ways the world manipulates you, in the end you realise that your core identity is a complex illusion created by neural networks.

limited by what is commonly referred to as dualism—the idea of a distinct and inherently real “self” that is separate from an apparently distinct and inherently real “other.” As we’ll explore later, dualism is not a “character flaw” or defect. It’s a complex survival mechanism deeply rooted in the structure and function of the brain—

If there is any instrument you must fall in love with and fetishize, it is the human brain—the most miraculous, awe-inspiring, information-processing tool devised in the known universe, with a complexity we can’t even begin to fathom, and with dimensional powers that far outstrip any piece of technology in sophistication and usefulness.

Just this past summer, I took online courses in introductory logic and law through civilization. Often the weight of history, with its facts heaped upon facts requiring complex chains of inference to sort through – I mean complex for someone with the soft brain of a tomato merchant; for me the premises are obvious and the conclusions dire and inescapable – threatened to crush me, and I was ultimately forced to abandon the whole undertaking. By way of recovery, I spent the rest of the summer immersed in a Freudian meditation on some choice tabloids. The mysterious lives of celebrities make for challenging induction. The reasoning process involves navigating many gaps in our knowledge of them. What is certain is that under the iceberg of glitz and glamor lie neurotic, depraved individuals with bizarre habits and hobbies, people who think they’re above the law.

My old age is a precious gift. My brain still works. I like my brain. I feel lighter. I am free of self-doubt, irrational desires, useless complexes, and other deadly sins that are not worth the trouble. I am letting go…letting go. I should have started earlier.

The five elements of the complex adaptive system are conformity enforcers, diversity generators, inner-judges, resource shifters, and intergroup tournaments.

you are part of a complex social network that changes your biology with every interaction, and which your actions can change

Asking where memory is "located" in the brain is like asking where running is located in the body. There are certainly parts of the body that are more important (the legs) or less important (the little fingers) in performing the task of running but, in the end, it is an activity that requires complex coordination among a great many body parts and muscle groups. To extend the analogy, looking for differences between memory systems is like looking for differences between running and walking. There certainly are many differences, but the main difference is that running requires more coordination among the different body parts and can be disrupted by small things (such as a corn on the toe) that may not interfere with walking at all. Are we to conclude, then, that running is located in the corn on your toe?

Generally speaking, our minds impose an entirely artificial order on the world. It is the only way that such an inadequate instrument as our brain can function. It cannot deal with the complexity of reality, so simplifies everything until it can, putting events into an artificial order so they can be dealt with one at a time, rather than all at once as they should be. Such a way of interpreting existence is learnt, rather in the way that our brain has to turn the images which hit our retinas upside down in order to make sense of them. Children

Their manipulation is psychological and emotionally devastating – and very dangerous, especially considering the brain circuitry for emotional and physical pain are one and the same (Kross, 2011). What a victim feels when they are punched in the stomach can be similar to the pain a victim feels when they are verbally and emotionally abused, and the effects of narcissistic abuse can be crippling and long-lasting, even resulting in symptoms of PTSD or Complex PTSD.

Brain scans prove that patients who’ve sustained significant childhood trauma have brains that look different from people who haven’t. Traumatized brains tend to have an enlarged amygdala—a part of the brain that is generally associated with producing feelings of fear. Which makes sense. But it goes further than that: For survivors of emotional abuse, the part of their brain that is associated with self-awareness and self-evaluation is shrunken and thin. Women who’ve suffered childhood sexual abuse have smaller somatosensory cortices—the part of the brain that registers sensation in our bodies. Victims who were screamed at might have an altered response to sound. Traumatized brains can result in reductions in the parts of the brain that process semantics, emotion and memory retrieval, perceiving emotions in others, and attention and speech. Not getting enough sleep at night potentially affects developing brains’ plasticity and attention and increases the risk of emotional problems later in life. And the scariest factoid, for me anyway: Child abuse is often associated with reduced thickness in the prefrontal cortex, the part of the brain associated with moderation, decision-making, complex thought, and logical reasoning. Brains do have workarounds. There are people without amygdalae who don’t feel fear. There are people who have reduced prefrontal cortices who are very logical. And other parts of the brain can compensate, make up the lost parts in other ways. But overall, when I looked at the breadth of evidence, the results felt crushing. The fact that the brain’s cortical thickness is directly related to IQ was particularly threatening to me. Even if I wasn’t cool, or kind, or personable, I enjoyed the narrative that I was at least effective. Intelligent. What these papers seemed to tell me is that however smart I am, I’m not as smart as I could have been had this not happened to me. The questions arose again: Is this why my pitches didn’t go through? Is this why my boss never respected me? Is this why I was pushed to do grunt work in the back room?

Biological instincts are the key to understanding how every single human being is wired. The marvelous interplay of various brain circuits creates our instinctual reality of the daily life. If you’re conscious about the fact that there lies a complex yet vividly beautiful brain circuit mechanism behind every single impulse of your daily emotions, then you can choose how to react upon each of those impulses. You can thus program your behavioral response in a certain situation.

My central premise is that although the reductionist approaches of scientists and artists are not identical in their aims—scientists use reductionism to solve a complex problem and artists use it to elicit a new perceptual and emotional response in the beholder—they are analogous. For example,

Life is simple, it has always been. What is complex is our brain, and that’s the main reason why we perceive life as being complicated. Embrace life for what you have and embrace life for who you are, as what you have others might envy and who you are might be secretly being admired by millions.

All the early stages took place in water: the origin of life; the birth of animals, the evolution of nervous systems and brains, and the appearance of complex bodies that makes brains worth having [...] When animals did crawl onto dry land, they took the sea with them. All the basic activities of life occur in water-filled cells bounded by membranes, tiny containers whose insides are remnants of the sea.

So who you are at any given moment depends on the detailed rhythms of your neuronal firing. During the day, the conscious you emerges from that integrated neural complexity. At night, when the interaction of your neurons changes just a bit, you disappear. Your loved ones have to wait until the next morning, when your neurons let the wave die and work themselves back into their complex rhythm. Only then do you return.

Scientists are cautiously beginning to question the view that the brain is the sole and absolute ruler over the body. The gut not only possesses an unimaginable number of nerves, those nerves are also unimaginably different from those of the rest of the body. The gut commands an entire fleet of signaling substances, nerve-insulation materials, and ways of connecting. There is only one other organ in the body that can compete with the gut for diversity—the brain. The gut’s network of nerves is called the “gut brain” because it is just as large and chemically complex as the gray matter in our heads. Were the gut solely responsible for transporting food and producing the occasional burp, such a sophisticated nervous system would be an odd waste of energy. Nobody would create such a neural network just to enable us to break wind. There must be more to it than that.

It has always been a mystery to me how Adam, Eve, and the serpent were taught the same language. Where did they get it? We know now, that it requires a great number of years to form a language; that it is of exceedingly slow growth. We also know that by language, man conveys to his fellows the impressions made upon him by what he sees, hears, smells and touches. We know that the language of the savage consists of a few sounds, capable of expressing only a few ideas or states of the mind, such as love, desire, fear, hatred, aversion and contempt. Many centuries are required to produce a language capable of expressing complex ideas. It does not seem to me that ideas can be manufactured by a deity and put in the brain of man. These ideas must be the result of observation and experience.

I found myself drawn to biology, with all its frustrating yet fascinating complexities. When I was twelve, I remember reading about axolotls, which are basically a species of salamander that has evolved to remain permanently in the aquatic larval stage. They manage to keep their gills (rather than trading them in for lungs, like salamanders or frogs) by shutting down metamorphosis and becoming sexually mature in the water. I was completely flabbergasted when I read that by simply giving these creatures the “metamorphosis hormone” (thyroid extract) you could make the axolotl revert back into the extinct, land-dwelling, gill-less adult ancestor that it had evolved from. You could go back in time, resurrecting a prehistoric animal that no longer exists anywhere on Earth. I also knew that for some mysterious reason adult salamanders don’t regenerate amputated legs but the tadpoles do. My curiosity took me one step further, to the question of whether an axolotl—which is, after all, an “adult tadpole”—would retain its ability to regenerate a lost leg just as a modern frog tadpole does. And how many other axolotl-like beings exist on Earth, I wondered, that could be restored to their ancestral forms by simply giving them hormones? Could humans—who are after all apes that have evolved to retain many juvenile qualities—be made to revert to an ancestral form, perhaps something resembling Homo erectus, using the appropriate cocktail of hormones? My mind reeled out a stream of questions and speculations, and I was hooked on biology forever. I found mysteries and possibilities everywhere.

Going for the brain. [He chuckles.] We talk about it today as if it is some feat of magic, like holy water or a silver bullet, but why wouldn’t destruction of the brain be the only way to annihilate these creatures? Isn’t it the only way to annihilate us as well? You mean human beings? [He nods.] Isn’t that all we are? Just a brain kept alive by a complex and vulnerable machine we call the body? The brain cannot survive if just one part of the machine is destroyed or even deprived of such necessities as food or oxygen. That is the only measurable difference between us and “The Undead.” Their brains do not require a support system to survive, so it is necessary to attack the organ itself.

The tape measures and weighing scales of the Victorian brain scientists have been supplanted by powerful neuroimaging technologies, but there is still a lesson to be learned from historical examples such as these. State-of-the-art brain scanners offer us unprecedented information about the structure and working of the brain. But don't forget that, once, wrapping a tape measure around the head was considered modern and sophisticated, and it's important not to fall into the same old traps. As we'll see in later chapters, although certain popular commentators make it seem effortlessly easy, the sheer complexity of the brain makes interpreting and understanding the meaning of any sex differences we find in the brain a very difficult task. But the first, and perhaps surprising, issue in sex differences research is that of knowing which differences are real and which, like the intially promising cephalic index, are flukes or spurious.

Because it is the last to mature, by definition the frontal cortex is the brain region least constrained by genes and most sculpted by experience. This must be so, to be the supremely complex social species that we are. Ironically, it seems that the genetic program of human brain development has evolved to, as much as possible, free the frontal cortex from genes.

One can truly say that the irresistible progress of natural science since the time of Galileo has made its first halt before the study of the higher parts of the brain, the organ of the most complicated relations of the animal to the external world. And it seems, and not without reason, that now is the really critical moment for natural science; for the brain, in its highest complexity—the human brain—which created and creates natural science, itself becomes the object of this science.

But the point is, when the writer turns to address the reader, he or she must not only speak to me—naively dazzled and wholly enchanted by the complexities of the trickery, and thus all but incapable of any criticism, so that, indeed, he can claim, if he likes, priestly contact with the greater powers that, hurled at him by the muse, travel the parsecs from the Universe’s furthest shoals, cleaving stars on the way, to shatter the specific moment and sizzle his brains in their pan, rattle his teeth in their sockets, make his muscles howl against his bones, and to galvanize his pen so the ink bubbles and blisters on the nib (nor would I hear her claim to such as other than a metaphor for the most profound truths of skill, craft, or mathematical and historical conjuration)—but she or he must also speak to my student, for whom it was an okay story, with just so much description.

My name is CRPS, or so they say But I actually go by; a few different names. I was once called causalgia, nearly 150 years ago And then I had a new name It was RSD, apparently so. I went by that name because the burn lived inside of me. Now I am called CRPS, because I have so much to say I struggle to be free. I don't have one symptom and this is where I change, I attack the home of where I live; with shooting/burning pains. Depression fills the mind of the body I belong, it starts to speak harsh to self, negativity growing strong. Then I start to annoy them; with the issues with sensitivity, You'd think the pain enough; but no, it wants to make you aware of its trembling disability. I silently make my move; but the screams are loud and clear, Because I enter your physical reality and you can't disappear. I confuse your thoughts; I contain apart of your memory, I cover your perspective, the fog makes it sometimes unbearable to see. I play with your temperature levels, I make you nervous all the time - I take away your independance and take away your pride. I stay with you by the day & I remind you by the night, I am an awful journey and you will struggle with this fight. Then there's a side to me; not many understand, I have the ability to heal and you can be my friend. Help yourself find the strength to fight me with all you have, because eventually I'll get tired of making you grow mad. It will take some time; remember I mainly live inside your brain, Curing me is hard work but I promise you, You can beat me if you feed love to my pain. Find the strength to carry on and feed the fears with light; hold on to the seat because, like I said, it's going to be a fight. But I hope to meet you, when your healthy and healed, & you will silenty say to me - I did this, I am cured is this real? That day could possibly come; closer than I want- After all I am a disease and im fighting for my spot. I won't deny from my medical angle, I am close to losing the " incurable " battle.

We should not be too quick to dismiss our own [ocular] arrangement. As so often in biology, the situation is more complex.....we have the advantage that our own light-sensitive cells are embedded directly in their support cells (the retinal pigment epithelium) with an excellent blood supply immediately underneath. Such an arrangement supports the continuous turnover of photosensitive pigments. The human retina consumes even more oxygen than the brain, per gram, making it the most energetic organ in the body.

Studies have shown consistently that while IQ bears a fairly close relationship to accomplishment among men, it bears essentially no relationship at all to accomplishment among women. (...) The adult occupations of the women, whose childhood IQ's were in the same range as the men's, were for the most part undistinguished. n fact, two-thirds of the women with genius-level IQ's of 170 or above were occupied as housewives or office workers. The waste of women's talent is a brain drain that affects the entire country.

an octopus may have half a billion nerve cells distributed between its brain and its “arms” (a mouse, by comparison, has only 75 to 100 million). There is a remarkable degree of organization in the octopus brain, with dozens of functionally distinct lobes in the brain and similarities to the learning and memory systems of mammals. Not only are cephalopods easily trained to discriminate test shapes and objects, but some can learn by observation, a power otherwise confined to certain birds and mammals. They have remarkable powers of camouflage and can signal complex emotions and intentions by changing their skin colors, patterns, and textures.

I woke up with a start, a little after 5:30 in the morning, to that wonderful feeling that lasts only a fraction of a second, when you don’t know where you are—not even what continent you’re on! I jumped up from the futon and went over to my computer to make a note of the few fragments of the dream I could still hold on to before they completely melted away in the mind’s morning fog. The complexity and the confusion of the adventure put me in a good mood: I take such dreams as a sign that my brain is in good working order.

You see, programmers tend to be arrogant, self-absorbed introverts. We didn’t get into this business because we like people. Most of us got into programming because we prefer to deeply focus on sterile minutia, juggle lots of concepts simultaneously, and in general prove to ourselves that we have brains the size of a planet, all while not having to interact with the messy complexities of other people.

What does it mean that the most popular and unifying form of entertainment in America circa 2014 features giant muscled men, mostly African-American, engaged in a sport that causes many of them to suffer brain damage? What does it mean that our society has transmuted the intuitive physical joys of childhood—run, leap, throw, tackle—into a corporatized form of simulated combat? That a collision sport has become the leading signifier of our institutions of higher learning, and the undisputed champ of our colossal Athletic Industrial Complex?

At the Emory University School of Medicine in 2013, researchers conducted an experiment with male mice. They exposed the mice to the smell of cherry blossoms, then gave them an electric shock. The mice came to associate the smell of cherry blossoms with danger. Eventually, the mice were able to identify the smell at trace concentrations. The smell receptors in their brain enlarged—they changed to identify the scent. Researchers even identified changes in the mice’s sperm. Then, after the mice had offspring, the researchers exposed this next generation of mice to the cherry blossom scent. Despite the fact that these mice had never smelled cherry blossoms before and had never been shocked, they still shuddered and jumped when it wafted into their cages. This generation of mice had inherited their parents’ trauma.

Almost every system we exist in is cruel, and it is our job to hold ourselves accountable to a moral center separate from the arbitrary ganglion of laws that, so often, get things wrong. This is the work we inherit as creatures with a complex brain, which comes with inexplicable joys, like love and sex and making out in cars, but also the duty of empathy, of understanding what it means when someone is stumbling.

Our brains replay every painful memory from the past and every possible scary scenario from the future over and over, just like a complex computer simulation, in an attempt to scare us away from threats before they can happen and regardless of the probability of their happening at all.

What mazes there are in this world. The branches of trees, the filigree of roots, the matrix of crystals, the streets her father re-created in his models. Mazes in the nodules on murex shells and in the textures of sycamore bark and inside the hollow bones of eagles. None more complicated than the human brain, Etienne would say, what may be the most complex object in existence; one wet kilogram within which spin universes. She

Barrett said that when we’re dehydrated, we don’t necessarily feel thirsty—we feel exhausted. When we have something odd happening in our stomach, our body doesn’t quite know if we have a menstrual cramp or a stomachache or if we need to poop. We might not even be aware for a long period of time that our stomach hurts. And this isn’t unique to people with PTSD. It’s normal, everyday bodily dissociation that we all suffer from. If we find ourselves in a shitty mood, we might not necessarily be mad about a certain trigger. We could just be running at a metabolic deficit. Our body might be screaming “I NEED FUNYUNS” while we project our hangriness onto, say, this poor sweaty schmuck who’s breathing too loud in the elevator. But Barrett said that PTSD does make these inclinations worse. It affects a variety of systems in the body, throwing them all out of whack. Our hearts might beat faster. Our lungs might pump harder. Our body budget can get tipped off-balance more easily. And when it does, our reactions to these deficits can feel outsized. “Make sure that you get enough sleep, make sure you exercise, make sure that you eat in a healthful way,” she told me when I asked her what I could do to be a better person. When I countered that that didn’t seem like enough, she kindly offered, “You know, all you can do is take as much responsibility as you can. And sometimes it’s the attempt that matters, you know, more than the success.” Then she chuckled at herself. “That’s a very Jewish mother response!” So, first step of hacking my brain: sustaining it with enough oxygen and nutrients

It is complicated,’ they say. I am so sick of this response. Many people use it repeatedly to escape depth and confronting reality. They use it to take solace in the fact that they don’t know (or don’t wish to know) the ugly truth of what is happening right in front of their eyes. They reduce crimes, injustice, war, pain, hunger, rape, and everything that must be unpacked, dissected, and confronted to this: ‘It is complicated.’ They say this about COVID-19, too. Oh, how I have grown to hate this response. Every time I hear this statement from someone, it sounds like ‘I am a loser’ to my ears. ‘It is complicated’ is the favorite response of lazy brains that refuse to think and do. Oh, my friends, I insist it is not complicated. If you really want to know, it is not so complicated. However, if you are really looking for reasons and excuses to justify your silence, complicity, and to protect your self-interest, then you are absolutely right – it is complicated!

The largest animal in the ocean and the largest living land animal were no more than a hundred yards apart, and I was convinced that they were communicating! In infrasound, in concert, sharing big brains and long lives, understanding the pain of high investment in a few precious offspring, aware of the importance and the pleasure of complex sociality, these rare and lovely great ladies were commiserating over the back fence of this rocky Cape shore, woman to woman, matriarch to matriarch,

DNA passes the blueprints of life between generations. Ever more complex life forms input information from sensors such as eyes and ears and process the information in brains or other systems to figure out how to act and then act on the world, by outputting information to muscles, for example. As some point during our 13.8 billion years of cosmic history, something beautiful happened. This information processing got so intelligent that life forms became conscious. Our universe has now awoken, becoming aware of itself. I regard it a triumph that we, who are ourselves mere stardust, have come to such a detailed understanding of the universe in which we live.

The complex tactile movement of writing by hand stimulates our mind more effectively than typing. It activates multiple regions of the brain simultaneously, thereby imprinting what we learn on a deeper level. As a result, we retain information longer than we would by tapping it into an app.18 In one study, college students who were asked to take lecture notes by hand tested better on average than those who had typed out their notes. They were also able to better retain this information long after the exam.

Hare and Tomasello think that the social behavior of chimps is constrained by their temperament, and the human temperament is necessary for more complex forms of social cognition. In order to develop the level of cooperation that is necessary for humans to live in large social groups, humans had to become less aggressive and less competitive.

Both scientists and laypeople can find themselves seduced into the easy trap of wanting to assign each function of the brain to a specific location. Perhaps because of pressure for simple sound bites, a steady stream of reports in the media (and even in the scientific literature) has created the false impression that the brain area for such-and-such has just been discovered. Such reports feed popular expectation and hope for easy labeling, but the true situation is much more interesting: the continuous networks of neural circuitry accomplish their functions using multiple, independently discovered strategies. The brain lends itself well to the complexity of the world, but poorly to clear-cut cartography.

human experiences are biopsychosocial: a complex interaction between the world around us, our personal experiences of it, and our bodies and brains, with all of those aspects influencing the others. We risk doing further damage to ourselves when we attempt to change our individual experience without recognizing the role of social injustice and/or cultural messages in our suffering.

As David Eagleman describes it in his wonderful book Incognito: Your brain is built of cells called neurons and glia—hundreds of billions of them. Each one of them is as complex as a city. . . . The cells [neurons] are connected in a network of such staggering complexity that it bankrupts human language and necessitates new strains of mathematics. A typical neuron makes about ten thousand connections to neighboring neurons. Given billions of neurons, this means that there are as many connections in a single cubic centimeter of brain tissue as there are stars in the Milky Way galaxy.

Archons are basically cosmic bureaucrats. They are demons. They seek to play God. In short, they are Alien Parasites. The Archons are in people’s minds and brains. They love to help people make mistakes, to the point that people are completely lost in confusion. Archons love to lead people into labyrinths of confusion and excessive complexity. Archons make people think that they are more powerful than humanity. Have hope! Do not give up. The Archons, in fact, are much less powerful than the Aeons who live in the Pleroma. If you strengthen your connection with Sophia, the Christos and the Aeons, you have nothing to fear.

It might weigh little over a kilogram but, taken on its own scale, the brain is unimaginably vast. One cubic millimetre contains between twenty and twenty-five thousand neurons. It has eighty-six billion of these cells, and each one is complex as a city and is in contact with ten thousand other neurons just like it. Within just one cubic centimetre of brain tissue, there is the same number of connections as there are stars in the Milky Way. Your brain contains a hundred trillion of them. Information in the form of electricity and chemicals flows around these paths in great forking trails and in circuits and feedback loops and fantastical storms of activity tat bloom to life speeds of up to a hundred and twenty metres per second. According to the neuroscientist V. S. Ramachandran, 'The number of permutations and combinations of activity that are theoretically possible exceeds the number of elementary particles in the universe.' And yet, he continues, 'We know so little about it that even a child's questions should be seriously entertained.

trauma increases the risk of misinterpreting whether a particular situation is dangerous or safe. You can get along with other people only if you can accurately gauge whether their intentions are benign or dangerous. Even a slight misreading can lead to painful misunderstandings in relationships at home and at work. Functioning effectively in a complex work environment or a household filled with rambunctious kids requires the ability to quickly assess how people are feeling and continuously adjusting your behavior accordingly. Faulty alarm systems lead to blowups or shutdowns in response to innocuous comments or facial expressions.

We assume that a large brain, the use of tools, superior learning abilities and complex social structures are huge advantages. It seems self-evident that these have made humankind the most powerful animal on earth. But humans enjoyed all of these advantages for a full 2 million years during which they remained weak and marginal creatures. Thus humans who lived a million years ago, despite their big brains and sharp stone tools, dwelt in constant fear of predators, rarely hunted large game, and subsisted mainly by gathering plants, scooping up insects, stalking small animals, and eating the carrion left behind by other more powerful carnivores.

[I]f he had to guess, he would say that the reason he doesn't want to loan the book out, to Ethan or anyone else, is because of the part of his personality that is one gigantic record-keeping system, a complex sifting and filing scheme that dictates what goes here and what goes there, turning his life into so many marks on a tablet. His mind would busy itself with the book's whereabouts every second it was away. He knows it would.

One guy yelled at me, 'You stupid bitch, how do you live like that with nothing in your brain?' Well, that did it. I wasn't going to put up with that. OK, so I'm not so smart. I'm working class. But it's the working class that keeps the world running, and it's the working classes that get exploited. What kind of revolution is it that just throws out big words that working-class people can't understand? What kind of crap social revolution is that? I mean, I'd like to make the world a better place, too. If somebody's really being exploited, we've got to put a stop to it. That's what I believe, and that's why I ask questions. (...) So that's when it hit me. These guys are fakes. All they've got on their minds is impressing the new girls with the big words they're so proud of, while sticking their hands up their skirts.(...) They marry pretty wives who've never read Marx and have kids they give fancy new names to that are enough to make you puke. Smash what educational-industrial complex? Don't make me laugh! (...) They're scared to death somebody's gonna find out they don't know something. They all read the same books and they all spout the same slogans, and they love listening to John Coltrane and seeing Pasolini movies. You call that 'revolution'? (...) Revolution or not, the working class will just keep on scraping a living in the same old shitholes. And what is a revolution? It sure as hell isn't just changing the name on city hall. But those guys don't know that - those guys with their big words.

I held a brain for the cameras at St Paul’s teaching hospital in Addis. It is the most complex single object in the known universe, a most intricate example of emergent complexity assembled over 4 billion years by natural selection operating within the constraints placed upon it by the laws of physics and the particular biochemistry of life on Earth. It contains around 85 billion individual neurons, which is of the same order as the number of stars in an average galaxy. But that doesn’t begin to describe its complexity. Each neuron is thought to make between 10,000 and 100,000 connections to other neurons, making the brain a computer way beyond anything our current technology can simulate. When we do manage to simulate one, I have no doubt that sentience will emerge; consciousness is not magic, it is an emergent property consistent with the known laws of nature.

Environmental influences also affect dopamine. From animal studies, we know that social stimulation is necessary for the growth of the nerve endings that release dopamine and for the growth of receptors that dopamine needs to bind to in order to do its work. In four-month-old monkeys, major alterations of dopamine and other neurotransmitter systems were found after only six days of separation from their mothers. “In these experiments,” writes Steven Dubovsky, Professor of Psychiatry and Medicine at the University of Colorado, “loss of an important attachment appears to lead to less of an important neurotransmitter in the brain. Once these circuits stop functioning normally, it becomes more and more difficult to activate the mind.” A neuroscientific study published in 1998 showed that adult rats whose mothers had given them more licking, grooming and other physical-emotional contact during infancy had more efficient brain circuitry for reducing anxiety, as well as more receptors on nerve cells for the brain’s own natural tranquilizing chemicals. In other words, early interactions with the mother shaped the adult rat’s neurophysiological capacity to respond to stress. In another study, newborn animals reared in isolation had reduced dopamine activity in their prefrontal cortex — but not in other areas of the brain. That is, emotional stress particularly affects the chemistry of the prefrontal cortex, the center for selective attention, motivation and self-regulation. Given the relative complexity of human emotional interactions, the influence of the infant-parent relationship on human neurochemistry is bound to be even stronger. In the human infant, the growth of dopamine-rich nerve terminals and the development of dopamine receptors is stimulated by chemicals released in the brain during the experience of joy, the ecstatic joy that comes from the perfectly attuned mother-child mutual gaze interaction. Happy interactions between mother and infant generate motivation and arousal by activating cells in the midbrain that release endorphins, thereby inducing in the infant a joyful, exhilarated state. They also trigger the release of dopamine. Both endorphins and dopamine promote the development of new connections in the prefrontal cortex. Dopamine released from the midbrain also triggers the growth of nerve cells and blood vessels in the right prefrontal cortex and promotes the growth of dopamine receptors. A relative scarcity of such receptors and blood supply is thought to be one of the major physiological dimensions of ADD. The letters ADD may equally well stand for Attunement Deficit Disorder.

There are some mysteries in this world," Yukawa said suddenly, "that cannot be unraveled with modern science. However, as science develops, we will one day be able to understand them. The question is, is there a limit to what science can know? If so, what creates that limit?" Kyohei looked at Yukawa. He couldn't figure out why the professor was telling him this, except he had a feeling it was very important. Yukawa pointed a finger at Kyohei's forehead. "People do." he said. "People's brains, to be more precise. For example, in mathematics, when somebody discovers a new theorem, they may have other mathematicians verify it to see if it's correct. The problem is, the theorems getting discovered are becoming more and more complex. That limits the number of mathematicians who can properly verify them. What happens when someone comes up with a theorem so hard to understand that there isn't anyone else who can understand it? In order for that theorem to be accepted as fact, they have to wait until another genius comes along. That's the limit the human brain imposes on the progress of scientific knowledge. You understand?" Kyohei nodded, still having no idea where he was going with this. "Every problem has a solution," Yukawa said, staring straight at Kyohei through his glasses. "But there's no guarantee that the solution will be found immediately. The same holds true in our lives. We encounter several problems to which the solutions are not immediately apparent in life. There is value to be had in worrying about those problems when you get to them. But never feel rushed. Often, in order to find the answer, you need time to grow first. That's why we apply ourselves, and learn as we go." Kyohei chewed on that for a moment, then his mouth opened a little and he looked up with sudden understanding. "You have questions now, I know, and until you find your answers, I'll be working on those questions too, and worrying with you. So don't forget, you're never alone.

Why should there be conscious experience at all? It is central to a subjective viewpoint, but from an objective viewpoint it is utterly unexpected. Taking the objective view, we can tell a story about how fields, waves, and particles in the spatiotemporal manifold interact in subtle ways, leading to the development of complex systems such as brains. In principle, there is no deep philosophical mystery in the fact that these systems can process information in complex ways, react to stimuli with sophisticated behavior, and even exhibit such complex capacities as learning, memory, and language. All this is impressive, but it is not metaphysically baffling. In contrast, the existence of conscious experience seems to be a new feature from this viewpoint. It is not something that one would have predicted from the other features alone. That is, consciousness is surprising. If all we knew about were the facts of physics, and even the facts about dynamics and information processing in complex systems, there would be no compelling reason to postulate the existence of conscious experience. If it were not for our direct evidence in the first-person case, the hypothesis would seem unwarranted; almost mystical, perhaps. Yet we know, directly, that there is conscious experience. The question is, how do we reconcile it with everything else we know?

Nature had once produced an Englishman whose domed head had been a hive of words; a man who had only to breathe on any particle of his stupendous vocabulary to have that particle live and expand and throw out tremulous tentacles until it became a complex image with a pulsing brain and correlated limbs. Three centuries later, another man, in another country, was trying to render these rhythms and metaphors in a different tongue. This process entailed a prodigious amount of labour, for the necessity of which no real reason could be given. It was as if someone, having seen a certain oak tree (further called Individual T) growing in a certain land and casting its own unique shadow on the green and brown ground, had proceeded to erect in his garden a prodigiously intricate piece of machinery which in itself was as unlike that or any other tree as the translator's inspiration and language were unlike those of the original author, but which, by means of ingenious combination of parts, light effects, breeze-engendering engines, would, when completed, cast a shadow exactly similar to that of Individual T - the same outline, changing in the same manner, with the same double and single spots of sun rippling in the same position, at the same hour of the day. From a practical point of view, such a waste of time and material (those headaches, those midnight triumphs that turn out to be disasters in the sober light of morning!) was almost criminally absurd, since the greatest masterpiece of imitation presupposed a voluntary limitation of thought, in submission to another man's genius.

Unsure what to do, I shed my clothes and turned on the shower. I lay down in the tub, knees drawn to my chest, arms wrapped tightly around myself as if I could physically hold the fragments of myself together. Water cascaded over my body and face, my breaths coming in short gasps as I grappled with the suddenly complex task of inhaling and exhaling. In that moment, with the water drumming against the porcelain, that chilling thought came: I want to die. The idea of not existing brought a perverse sense of relief, even as the rational part of my brain fought against it. The rational part of my brain fought back. No, God wants you alive, Shari. This must all be part of His plan.

Imagine, Bishop, that you have a beloved cat, but that your cat is not with you. If you close your eyes and further imagine you are petting your cat, the same neurons in your brains are activated as if you were petting the actual cat. Our minds may know the difference between its models and reality itself, but it prefers its models. So much so that we apprehend reality through our models, rather than directly via the sense. When I'm speaking to you, I have a little bishop in my head, and though I speak out load, I'm speaking to my little bishop. When you answer, I can only perceive you through my model of you. Mentars also make models, but they don't apprehend reality through them. They end up, not with little people in their minds, but with highly complex rule sets. They relate to their models in the same way we relate to weather models, as things to consult, but not to conflate with external reality.

The problem with romance is the occlusion. The tunnel vision, drawing your every gaze downstream, into those other eyes, the flotsam of your better self, your clearer self, along for the ride. It doesn't matter what secrets swirl and bob in the waters beneath you, as you float toward that lady at Delphi, who, you imagined, reading Mythology, must have been beautiful. It doesn't matter that Charybdis, with no body, with no form, with only a mouth-as-being, couldn't have been evil, because she lacked the brain for it. It doesn't matter that following the logical course of events, the natural course, always disadvantages someone else, because love, after all, is simply a competition for resources, made infinitely complex and unknowable when squared and cubed and raised to every other emotional exponent - and then layered with sex and society and a bad memory for what those resources were in the first place.

Throughout the human life span there remains a constant two-way interaction between psychological states and the neurochemistry of the frontal lobes, a fact that many doctors do not pay enough attention to. One result is the overreliance on medications in the treatment of mental disorders. Modern psychiatry is doing too much listening to Prozac and not enough listening to human beings; people’s life histories should be given at least as much importance as the chemistry of their brains. The dominant tendency is to explain mental conditions by deficiencies of the brain’s chemical messengers, the neurotransmitters. As Daniel J. Siegel has sharply remarked, “We hear it said everywhere these days that the experience of human beings comes from their chemicals.” Depression, according to the simple biochemical model, is due to a lack of serotonin — and, it is said, so is excessive aggression. The answer is Prozac, which increases serotonin levels in the brain. Attention deficit is thought to be due in part to an undersupply of dopamine, one of the brain’s most important neurotransmitters, crucial to attention and to experiencing reward states. The answer is Ritalin. Just as Prozac elevates serotonin levels, Ritalin or other psychostimulants are thought to increase the availability of dopamine in the brain’s prefrontal areas. This is believed to increase motivation and attention by improving the functioning of areas in the prefrontal cortex. Although they carry some truth, such biochemical explanations of complex mental states are dangerous oversimplifications — as the neurologist Antonio Damasio cautions: "When it comes to explaining behavior and mind, it is not enough to mention neurochemistry... The problem is that it is not the absence or low amount of serotonin per se that “causes” certain manifestations. Serotonin is part of an exceedingly complicated mechanism which operates at the level of molecules, synapses, local circuits, and systems, and in which sociocultural factors, past and present, also intervene powerfully. The deficiencies and imbalances of brain chemicals are as much effect as cause. They are greatly influenced by emotional experiences. Some experiences deplete the supply of neurotransmitters; other experiences enhance them. In turn, the availability — or lack of availability — of brain chemicals can promote certain behaviors and emotional responses and inhibit others. Once more we see that the relationship between behavior and biology is not a one-way street.

I'm afraid they're not very well-designed creatures, dragons." Vimes listened. "They would never have survived at all except that their home swamps were isolated and short of predators. Not that a dragon made good eating, anyway-once you'd taken away the leathery skin and the enormous flight muscles, what was left must have been like biting into a badly-run chemical factory. No wonder dragons were always ill. They relied on permanent stomach trouble for supplies of fuel. Most of their brain power was taken up with controlling the complexities of then-digestion, which could distill flame-producing fuels from the most unlikely ingredients. They could even rearrange their internal plumbing overnight to deal with difficult processes. They lived on a chemical knife-edge the whole time. One misplaced hiccup and they were geography. And when it came to choosing nesting sites, the females had all the common sense and mothering instinct of a brick." Vimes wondered why people had been so worried about dragons in the olden days. If there was one in a cave near you, all you had to do was wait until it self-ignited, blew itself up, or died of acute indigestion.

There is a ton of literature now—including TED Talks and Michael Pollan’s book How to Change Your Mind—about psilocybin and MDMA being highly effective medications for PTSD. Anecdotal stories abound of suffering veterans emerging from one meaningful trip completely cured, with a new vigor for life. Shrooms in particular have proved to be a great salve for people with terminal illnesses. The oncoming specter of death can be terrifying, but after these suffering patients emerge from their hallucinogenic experiences, many are at peace with their lives and deaths, content to be absorbed back into the fabric of the universe. Shrooms have also been shown to suppress your DMN and dissolve your ego, allowing you to look at your life with a childlike, brand-new perspective. They can draw connections between disparate parts of the brain, building creative solutions to our life’s struggles and strengthening areas we don’t use frequently enough.

In 90% of cases, you can start with one of the two most effective ways to open a speech: ask a question or start with a story. Our brain doesn’t remember what we hear. It remembers only what we “see” or imagine while we listen. You can remember stories. Everything else is quickly forgotten. Smell is the most powerful sense out of 4 to immerse audience members into a scene. Every sentence either helps to drive your point home, or it detracts from clarity. There is no middle point. If you don’t have a foundational phrase in your speech, it means that your message is not clear enough to you, and if it’s not clear to you, there is no way it will be clear to your audience. Share your failures first. Show your audience members that you are not any better, smarter or more talented than they are. You are not an actor, you are a speaker. The main skill of an actor is to play a role; to be someone else. Your main skill as a speaker is to be yourself. People will forgive you for anything except for being boring. Speaking without passion is boring. If you are not excited about what you are talking about, how can you expect your audience to be excited? Never hide behind a lectern or a table. Your audience needs to see 100% of your body. Speak slowly and people will consider you to be a thoughtful and clever person. Leaders don’t talk much, but each word holds a lot of meaning and value. You always speak to only one person. Have a conversation directly with one person, look him or her in the eye. After you have logically completed one idea, which usually is 10-20 seconds, scan the audience and then stop your eyes on another person. Repeat this process again. Cover the entire room with eye contact. When you scan the audience and pick people for eye contact, pick positive people more often. When you pause, your audience thinks about your message and reflects. Pausing builds an audiences’ confidence. If you don’t pause, your audience doesn’t have time to digest what you've told them and hence, they will not remember a word of what you've said. Pause before and after you make an important point and stand still. During this pause, people think about your words and your message sinks in. After you make an important point and stand still. During this pause, people think about your words and your message sinks in. Speakers use filler words when they don’t know what to say, but they feel uncomfortable with silence. Have you ever seen a speaker who went on stage with a piece of paper and notes? Have you ever been one of these speakers? When people see you with paper in your hands, they instantly think, “This speaker is not sincere. He has a script and will talk according to the script.” The best speeches are not written, they are rewritten. Bad speakers create a 10 minutes speech and deliver it in 7 minutes. Great speakers create a 5 minute speech and deliver it in 7 minutes. Explain your ideas in a simple manner, so that the average 12-year-old child can understand the concept. Good speakers and experts can always explain the most complex ideas with very simple words. Stories evoke emotions. Factual information conveys logic. Emotions are far more important in a speech than logic. If you're considering whether to use statistics or a story, use a story. PowerPoint is for pictures not for words. Use as few words on the slide as possible. Never learn your speech word for word. Just rehearse it enough times to internalize the flow. If you watch a video of your speech, you can triple the pace of your development as a speaker. Make videos a habit. Meaningless words and clichés neither convey value nor information. Avoid them. Never apologize on stage. If people need to put in a lot of effort to understand you they simply won’t listen. On the other hand if you use very simple language you will connect with the audience and your speech will be remembered.

In all of these areas, the human brain is asked to do and handle more than ever before. We are dealing with several fields of knowledge constantly intersecting with our own, and all of this chaos is exponentially increased by the information available through technology. What this means is that all of us must possess different forms of knowledge and an array of skills in different fields, and have minds that are capable of organizing large amounts of information. The future belongs to those who learn more skills and combine them in creative ways. And the process of learning skills, no matter how virtual, remains the same. In the future, the great division will be between those who have trained themselves to handle these complexities and those who are overwhelmed by them—those who can acquire skills and discipline their minds and those who are irrevocably distracted by all the media around them and can never focus enough to learn. The Apprenticeship Phase is more relevant and important than ever, and those who discount this notion will almost certainly be left behind. Finally, we live in a culture that generally values intellect and reasoning with words. We tend to think of working with the hands, of building something physical, as degraded skills for those who are less intelligent. This is an extremely counterproductive cultural value. The human brain evolved in intimate conjunction with the hand. Many of our earliest survival skills depended on elaborate hand-eye coordination. To this day, a large portion of our brain is devoted to this relationship. When we work with our hands and build something, we learn how to sequence our actions and how to organize our thoughts. In taking anything apart in order to fix it, we learn problem-solving skills that have wider applications. Even if it is only as a side activity, you should find a way to work with your hands, or to learn more about the inner workings of the machines and pieces of technology around you. Many Masters

We know, however, that the mind is capable of understanding these matters in all their complexity and in all their simplicity. A ball flying through the air is responding to the force and direction with which it was thrown, the action of gravity, the friction of the air which it must expend its energy on overcoming, the turbulence of the air around its surface, and the rate and direction of the ball's spin. And yet, someone who might have difficulty consciously trying to work out what 3 x 4 x 5 comes to would have no trouble in doing differential calculus and a whole host of related calculations so astoundingly fast that they can actually catch a flying ball. People who call this "instinct" are merely giving the phenomenon a name, not explaining anything. I think that the closest that human beings come to expressing our understanding of these natural complexities is in music. It is the most abstract of the arts - it has no meaning or purpose other than to be itself. Every single aspect of a piece of music can be represented by numbers. From the organization of movements in a whole symphony, down through the patterns of pitch and rhythm that make up the melodies and harmonies, the dynamics that shape the performance, all the way down to the timbres of the notes themselves, their harmonics, the way they change over time, in short, all the elements of a noise that distinguish between the sound of one person piping on a piccolo and another one thumping a drum - all of these things can be expressed by patterns and hierarchies of numbers. And in my experience the more internal relationships there are between the patterns of numbers at different levels of the hierarchy, however complex and subtle those relationships may be, the more satisfying and, well, whole, the music will seem to be. In fact the more subtle and complex those relationships, and the further they are beyond the grasp of the conscious mind, the more the instinctive part of your mind - by which I mean that part of your mind that can do differential calculus so astoundingly fast that it will put your hand in the right place to catch a flying ball- the more that part of your brain revels in it. Music of any complexity (and even "Three Blind Mice" is complex in its way by the time someone has actually performed it on an instrument with its own individual timbre and articulation) passes beyond your conscious mind into the arms of your own private mathematical genius who dwells in your unconscious responding to all the inner complexities and relationships and proportions that we think we know nothing about. Some people object to such a view of music, saying that if you reduce music to mathematics, where does the emotion come into it? I would say that it's never been out of it.

At parties, people no longer showed off their new gadgets, jewelry, or hairstyles, but prosthetic cochleas that improved the sense of balance, artificial muscles with augmented contraction characteristics, prosthetic limbs that obeyed mental directions, or updated firmware that enhanced sensory organs. SBT developed a revolutionary substance for mediating between the biological and the electronic worlds. Extracted from the gladii of squids, this modified chitosan complex could convert the biological ion flow that carried brain signals into electric currents that could be deciphered by machines, thereby seamlessly forming a feedback loop between the nervous system and the prosthesis. The invention had expanded the definition of the boundary of the body beyond imagination.

The Human Genome Project, the full sequence of the normal human genome, was completed in 2003. In its wake comes a far less publicized but vastly more complex project: fully sequencing the genomes of several human cancer cells. Once completed, this effort, called the Cancer Genome Atlas, will dwarf the Human Genome Project in its scope. The sequencing effort involves dozens of teams of researchers across the world. The initial list of cancers to be sequenced includes brain, lung, pancreatic, and ovarian cancer. The Human Genome Project will provide the normal genome, against which cancer’s abnormal genome can be juxtaposed and contrasted. The result, as Francis Collins, the leader of the Human Genome Project describes it, will be a “colossal atlas” of cancer—a compendium of every gene mutated in the most common forms of cancer: “When applied to the 50 most common types of cancer, this effort could ultimately prove to be the equivalent of more than 10,000 Human Genome Projects in terms of the sheer volume of DNA to be sequenced.

Our visual field, the entire view of what we can see when we look out into the world, is divided into billions of tiny spots or pixels. Each pixel is filled with atoms and molecules that are in vibration. The retinal cells in the back of our eyes detect the movement of those atomic particles. Atoms vibrating at different frequencies emit different wavelengths of energy, and this information is eventually coded as different colors by the visual cortex in the occipital region of our brain. A visual image is built by our brain's ability to package groups of pixels together in the form of edges. Different edges with different orientations - vertical, horizontal and oblique, combine to form complex images. Different groups of cells in our brain add depth, color and motion to what we see.

Perhaps there are many "nows" of varying duration, depending on just what it is we are doing. We must face up to the fact that, at least in the case of humans, the subject experiencing subjective time is not a perfect, structureless observer, but a complex, multilayered, multifaceted psyche. Different levels of our consciousness may experience time in quite different ways. This is evidently the case in terms of response time. You have probably had the slightly unnerving experience of jumping at the sound of a telephone a moment or two before you actually hear it ring. The shrill noise induces a reflex response through the nervous system much faster than the time it takes to create the conscious experience of the sound. It is fashionable to attribute certain qualities, such as speech ability, to the left side of the brain, whereas others, such as musical appreciation, belong to processes occurring on the right side. But why should both hemispheres experience a common time? And why should the subconscious use the same mental clock as the conscious?

We can think about our own thoughts, reason about our own reasons, and communicate with each other through a shared language. We can access the machine code running in our brains by translating high-level abstract concepts into causally efficacious patterns of neural activity. This gives a physical basis for how decisions are made in real time, not just as the outcome of complex physical interactions but also for consciously accessible reasons, and it provides a firm footing for the otherwise troublesome concept of mental causation.

You can get along with other people only if you can accurately gauge whether their intentions are benign or dangerous. Even a slight misreading can lead to painful misunderstandings in relationships at home and at work. Functioning effectively in a complex work environment or a household filled with rambunctious kids requires the ability to quickly assess how people are feeling and continuously adjusting your behavior accordingly. Faulty alarm systems lead to blowups or shutdowns in response to innocuous comments or facial expressions.

What gives us word-users the right to make life-and-death decisions concerning other living creatures that have no words? Why do we find ourselves in positions of such anguish (at least for some of us)? In the final analysis, it is simply because might makes right, and we humans, thanks to the intelligence afforded us by the complexity of our brains and our embeddedness in rich languages and cultures, are indeed high and mighty, relative to the “lower” animals (and vegetables). By virtue of our might, we are forced to establish some sort of ranking of creatures, whether we do so as a result of long and careful personal reflections or simply go along with the compelling flow of the masses. Are cows just as comfortably killable as mosquitoes? Would you feel any less troubled by swatting a fly preening on a wall than by beheading a chicken quivering on a block?

So it was that the Red Tower put into production its new, more terrible and perplexing, line of unique novelty items. Among the objects and constructions now manufactured were several of an almost innocent nature. These included tiny, delicate cameos that were heavier than their size would suggest, far heavier, and lockets whose shiny outer surface flipped open to reveal a black reverberant abyss inside, a deep blackness roaring with echoes. Along the same lines was a series of lifelike replicas of internal organs and physiological structures, many of them evidencing an advanced stages of disease and all of them displeasingly warm and soft to the touch. There was a fake disembodied hand on which fingernails would grow several inches overnight and insistently grew back should one attempt to clip them. Numerous natural objects, mostly bulbous gourds, were designed to produce a long, deafening scream whenever they were picked up or otherwise disturbed in their vegetable stillness. Less scrutable were such things as hardened globs of lava into whose rough, igneous forms were sent a pair of rheumy eyes that perpetually shifted their gaze from side to side like a relentless pendulum. And there was also a humble piece of cement, a fragment broken away from any street or sidewalk, that left a most intractable stain, greasy and green, on whatever surface it was placed. But such fairly simple items were eventually followed, and ultimately replaced, by more articulated objects and constructions. One example of this complex type of novelty item was an ornate music box that, when opened, emitted a brief gurgling or sucking sound in emulation of a dying individual's death rattle. Another product manufactured in great quantity at the Red Tower was a pocket watch in a gold casing which opened to reveal a curious timepiece whose numerals were represented by tiny quivering insects while the circling 'hands' were reptilian tongues, slender and pink. But these examples hardly begin to hint at the range of goods that came from the factory during its novelty phase of production. I should at least mention the exotic carpets woven with intricate abstract patterns that, when focused upon for a certain length of time, composed themselves into fleeting phantasmagoric scenes of a kind which might pass through a fever-stricken or even permanently damaged brain.

These computer simulations try only to duplicate the interactions between the cortex and the thalamus. Huge chunks of the brain are therefore missing. Dr. [Dharmendra] Modha understands the enormity of his project. His ambitious research has allowed him to estimate what it would take to create a working model of the entire human brain, and not just a portion or a pale version of it, complete with all parts of the neocortex and connections to the senses. He envisions using not just a single Blue Gene computer [with over a hundred thousand processors and terabytes of RAM] but thousands of them, which would fill up not just a room but an entire city block. The energy consumption would be so great that you would need a thousand-megawatt nuclear power plant to generate all the electricity. And then, to cool off this monstrous computer so it wouldn't melt, you would need to divert a river and send it through the computer circuits. It is remarkable that a gigantic, city-size computer is required to simulate a piece of human tissue that weighs three pounds, fits inside your skull, raises your body temperature by only a few degrees, uses twenty watts of power, and needs only a few hamburgers to keep it going.

Imagine if you will—and you will—a mushroom cloud bigger than anything that you currently see out that window. Imagine jet planes and bombers the size of apartment complexes dropping technological marvels of deconstruction upon this city, this world, all around the epicenter of a blooming death cloud. Imagine that mushroom coming to a head, knowing that it is filled with unimaginable heat and concrete, dust, papers—human faces, eyes, and brains. Gray matter filling the radioactive cloud with electricity as all that is inside us leaves us and becomes one with the mushroom. Glass will melt and connect with steel, and we will melt and connect with each other as everything that made us whole is criminally dissected and rearranged. Everything below us, from the sewer tunnels to the subway line, will be consumed into the cloud and jettisoned into the stratosphere, where it will become nothing but silken ash, hardened to a black substance, and turned back to a black dust, transfixed into a black nothing. A stinking, glowing crater all that remains of where you had your first kiss and told someone that you loved them. A mess of a world where everything you’ve ever done quickly becomes all that you’ll ever do.

It had mostly been around his mommy that time, and he had been in constant terror that she would pluck the word from her brain and drag it out of her mouth, making it real. DIVORCE. It was a constant undercurrent in their thoughts, one of the few he could always pick up, like the beat of simple music. But like a beat, the central thought formed only the spine of more complex thoughts, thoughts he could not as yet even begin to interpret. They came to him only as colors and moods. Mommy’s DIVORCE thoughts centered around what Daddy had done to his arm, and what had happened at Stovington when Daddy lost his job.

If you imagine complex, challenging possibilities, your brain will adapt to them. Much like a tiger trapped in a zoo exhibits repetitive displacement behavior, if you cage your imagination within the bars of the dull and neurotic, which often portray one’s fears more than they do an empirical “truth,” then your brain will adapt to these imagined meanings, too. Like the sad tiger pacing back and forth within its puny cage, your brain too will ruminate cyclically upon destructive meanings, and in doing so make them more significant than they might need to be. This present perceptual meaning becomes part of your future history of meanings, together with the meaning (and re-meanings) of past events, thus shaping your future perception. If you don’t want to let received contexts limit possibility, then you need to walk in the darkest forest of all—the one in your own skull—and face down the fear of ideas that challenge.

Finally, some scientists concede that consciousness is real and may actually have great moral and political value, but that it fulfils no biological function whatsoever. Consciousness is the biologically useless by-product of certain brain processes. Jet engines roar loudly, but the noise doesn’t propel the aeroplane forward. Humans don’t need carbon dioxide, but each and every breath fills the air with more of the stuff. Similarly, consciousness may be a kind of mental pollution produced by the firing of complex neural networks. It doesn’t do anything. It is just there. If this is true, it implies that all the pain and pleasure experienced by billions of creatures for millions of years is just mental pollution. This is certainly a thought worth thinking, even if it isn’t true. But it is quite amazing to realise that as of 2016, this is the best theory of consciousness that contemporary science has to offer us. Maybe

We live in the era of the “bottom line” mentality, with TED talks, sound bites, and news summaries. There is so much information to digest, we can only hope to grasp the world with compact and seemingly complete stories. We don’t want to be left dangling. We are all suckers for this information diet, and we all have come to depend on it, just like we have all succumbed to the instant gratification of texting and cell phones. And yet what separates the dilettante from the sophisticate is the appreciation that everything is not simple. The trick seems to be able to talk clearly while remaining fully aware of the underlying complexity of any story. For me it is the overwhelming realization that when trying to figure out how the brain does its masterful trick of enabling minds, we are barely at the starting line. Dig as deep as you want into human history: As long as there is a written record of thought, there is a record of humans wondering about the nature of life. It becomes obvious that all of us are just hopping into an ongoing conversation, not structuring one with a beginning, a middle, and an end. Humans may have discovered some of the constraints on the thought processes, but we have not yet been able to tell the full story.

If .. one can never step into the same river twice .. one will always be taken unawares by experience .. nothing can ever be known. We have to find a way of fixing it as it flies, stepping back from the immediacy of experience, stepping outside the flow. Hence the brain has to attend to the world in two completely different ways. In one, we experience - the live, complex, embodied, world of individual, always unique beings, forever in flux, a net of interdependencies, forming and reforming wholes, a world with which we are deeply connected. In the other we experience in a special way: a re-presented version .. containing now static, separable, bounded, but essentially fragmented entities, grouped into classes, on which predictions can be based. This kind of attention isolates, fixes and makes each thing explicit by bringing it under the spotlight of attention.. it renders things inert, mechanical, lifeless. But it also enables us to for the first time to know.. This gives us power.

One of the hardest things to grasp about implicit bias and racism is that your beliefs and values do not always drive your behavior. These beliefs and values are stored in the highest, most complex part of your brain—the cortex. But other parts of your brain can make associations—distorted, inaccurate, racist associations. The same person can have very sincere anti-racist beliefs but still have implicit biases that result in racist comments or actions. Understanding sequential processing in the brain is essential to grasping this, as is appreciating the power of developmental experiences to load the lower parts of our brain with all kinds of associations that create our worldview.

Some scientists used to side with my initial gut instinct—they believed it was possible for people to do several complex tasks at once. So they started to get people into labs, and they told them to do lots of things at the same time, and they monitored how well it went. What the scientists discovered is that, in fact, when people think they’re doing several things at once, they’re actually—as Earl explained—“juggling. They’re switching back and forth. They don’t notice the switching because their brain sort of papers it over, to give a seamless experience of consciousness, but what they’re actually doing is switching and reconfiguring their brain moment to moment, task to task—[and] that comes with a cost.” There are three ways, he explained, in which this constant switching degrades your ability to focus. The first is called the “switch cost effect.” There is broad scientific evidence for this. Imagine you are doing your tax return and you receive a text, and you look at it—it’s only a glance, taking five seconds—and then you go back to your tax return. In that moment, “your brain has to reconfigure, when it goes from one task to another,” he said. You have to remember what you were doing before, and you have to remember what you thought about it, “and that takes a little bit of time.” When this happens, the evidence shows that “your performance drops. You’re slower. All as a result of the switching.

It is important to note that the design of an entire brain region is simpler than the design of a single neuron. As discussed earlier, models often get simpler at a higher level—consider an analogy with a computer. We do need to understand the detailed physics ofsemiconductors to model a transistor, and the equations underlying a single real transistor are complex. A digital circuit that multiples two numbers requires hundreds of them. Yet we can model this multiplication circuit very simply with one or two formulas. An entire computer with billions of transistors can be modeled through its instruction set and register description, which can be described on a handful of written pages of text and formulas. The software programs for an operating system, language compilers, and assemblers are reasonably complex, but modeling a particular program—for example, a speech recognition programbased on hierarchical hidden Markov modeling—may likewise be described in only a few pages of equations. Nowhere in such a description would be found the details ofsemiconductor physics or even of computer architecture. A similar observation holds true for the brain. A particular neocortical pattern recognizer that detects a particular invariant visualfeature (such as a face) or that performs a bandpass filtering (restricting input to a specific frequency range) on sound or that evaluates the temporal proximity of two events can be described with far fewer specific details than the actual physics and chemicalrelations controlling the neurotransmitters, ion channels, and other synaptic and dendritic variables involved in the neural processes. Although all of this complexity needs to be carefully considered before advancing to the next higher conceptual level, much of it can be simplified as the operating principles of the brain are revealed.

The difference between supermind and Big Mind (if we take Big Mind to mean the state experience of nondual Suchness, or turiyatita) is that Big Mind can be experienced or recognized at virtually any lower level or rung. Magic to Integral. In fact, one can be at, say, the Pluralistic stage, and experience several core characteristics of the entire sequence of state-stages (gross to subtle to causal to Witnessing to Nondual), although, of course, the entire sequence, including nondual Suchness, will be interpreted in Pluralistic terms. This is unfortunate in many ways—interpreting Dharma in merely Pluralistic terms (or Mythic terms, or Rational, and so on)—because it is so ultimately reductionistic; but it happens all the time, given the relative independence of states and structures at 1st and 2nd tier. Supermind, on the other hand, as a basic structure-rung (conjoined with nondual Suchness) can only be experienced once all the previous junior levels have emerged and developed, and as in all structure development, stages cannot be skipped. Therefore, unlike Big Mind, supermind can only be experienced after all 1st-, 2nd-, and 3rd-tier junior stages have been passed through. While, as Genpo Roshi has abundantly demonstrated, Big Mind state experience is available to virtually anybody at almost any age (and will be interpreted according to the View of their current stage), supermind is an extremely rare recognition. Supermind, as the highest structure-rung to date, has access to all previous structures, all the way back to Archaic—and the Archaic itself, of course, has transcended and included, and now embraces, every major structural evolution going all the way back to the Big Bang. (A human being literally enfolds and embraces all the major transformative unfoldings of the entire Kosmic history—strings to quarks to subatomic particles to atoms to molecules to cells, all the way through the Tree of Life up to its latest evolutionary emergent, the triune brain, the most complex structure in the known natural world.) Supermind, in any given individual, is experienced as a type of “omniscience”—the supermind, since it transcends and includes all of the previous structure-rungs, and inherently is conjoined with the highest nondual Suchness state, has a full and complete knowledge of all of the potentials in that person. It literally “knows all,” at least for the individual.

Brain scans prove that patients who’ve sustained significant childhood trauma have brains that look different from those of people who haven’t.[8] Traumatized brains tend to have an enlarged amygdala—a part of the brain that is generally associated with producing feelings of fear. Which makes sense. But it goes further than that: For survivors of emotional abuse, the part of their brain that is associated with self-awareness and self-evaluation is shrunken and thin. Women who’ve suffered childhood sexual abuse have smaller somatosensory cortices—the part of the brain that registers sensation in our bodies. Victims who were screamed at might have an altered response to sound. Trauma can result in reductions in the parts of the brain that process semantics, emotion and memory retrieval, perceiving emotions in others, and attention and speech. Not getting enough sleep at night potentially affects developing brains’ plasticity and attention and increases the risk of emotional problems later in life. And the scariest factoid, for me anyway: Child abuse is often associated with reduced thickness in the prefrontal cortex, the part of the brain associated with moderation, decision-making, complex thought, and logical reasoning.

As for how much aerobic exercise you need to stay sharp, one small but scientifically sound study from Japan found that jogging thirty minutes just two or three times a week for twelve weeks improved executive function. But it’s important to mix in some form of activity that demands coordination beyond putting one foot in front of the other. Greenough worked on an experiment several years ago in which running rats were compared to others that were taught complex motor skills, such as walking across balance beams, unstable objects, and elastic rope ladders. After two weeks of training, the acrobatic rats had a 35 percent increase of BDNF in the cerebellum, whereas the running rats had none in that area. This extends what we know from the neurogenesis research: that aerobic exercise and complex activity have different beneficial effects on the brain.

is easy to recall from everyday experience that neither electricity nor magnetism have visual properties. So, on its own, it’s not hard to grasp that there is nothing inherently visual, nothing bright or colored about that candle flame. Now let these same invisible electromagnetic waves strike a human retina, and if (and only if) the waves each happen to measure between 400 and 700 nanometers in length from crest to crest, then their energy is just right to deliver a stimulus to the 8 million cone-shaped cells in the retina. Each in turn sends an electrical pulse to a neighbor neuron, and on up the line this goes, at 250 mph, until it reaches the warm, wet occipital lobe of the brain, in the back of the head. There, a cascading complex of neurons fire from the incoming stimuli, and we subjectively perceive this experience as a yellow brightness occurring in a place we have been conditioned to call “the external world.” Other creatures receiving the identical stimulus will experience something altogether different, such as a perception of gray, or even have an entirely dissimilar sensation. The point is, there isn’t a “bright yellow” light “out there” at all. At most, there is an invisible stream of electrical and magnetic pulses. We are totally necessary for the experience of what we’d call a yellow flame. Again, it’s correlative.

Nowadays, to be sure, we are more “comprehensive.” In particular, we pay more attention to the body. It may even be that we go too far. On the other hand, are there not too many intellectuals about who, without knowing it, have put a muzzle on their hearts, and whose “spiritual life” misses those deep intuitions that are of the world of the spirit? All these people–the “brains,” the spiritualists, as well as those who are embarrassed or engrossed by the body–may be taught Yoga (I saw “may,” because they have to give themselves to it) that they cannot become truly themselves unless they accept their nature as men and aim at establishing balance between the parts of man in is; this nature of ours which is at one and the same time an animal body (corpus-anima), thinking soul (animus-mens) and spirit (spiritus-cor). It is a harmony among these “three” that is sought in each of us by the grace of redemption. Christ came in the first place so that this “creature of God” within us, concealed under a human complex, bruised and torn by original sin, should flower and open out in its full beauty and wealth of talent. Any ascetic discipline that works towards this works, in fact, hand in hand with grace, and that is why I have roundly stated that a Yoga that calms the senses, pacifies the soul, and frees certain intuitive or affective powers in us can be of inestimable service to the West. It can make people into true Christians, dynamic and open, by helping them to be men.

We do not inhabit a perfected world where natural selection ruthlessly scrutinizes all organic structures and then molds them for optimal utility. Organisms inherit a body form and a style of embryonic development; these impose constraints upon future change and adaptation. In many cases, evolutionary pathways reflect inherited patterns more than current environmental demands. These inheritances constrain, but they also provide opportunity. A potentially minor genetic change […] entails a host of complex, nonadaptive consequences. The primary flexibility of evolution may arise from nonadaptive by-products that occasionally permit organisms to strike out in new and unpredictable directions. What “play” would evolution have if each structure were built for a restricted purpose and could be used for nothing else? How could humans learn to write if our brain had not evolved for hunting, social cohesion, or whatever, and could not transcend the adaptive boundaries of its original purpose?

A major push is under way to figure out the molecular basis of those "critical" or "sensitive" periods, to figure out how the brain changes as certain learning abilities come and go. In some, if not all, of those mammals that have the alternating stripes in the visual cortex known as ocular dominance columns, those columns can be adjusted early in development, but not in adulthood. A juvenile monkey that has one eye covered for an extended period of time can gradually readjust its brain wiring to favor the open eye; an adult monkey cannot adjust its wiring. At the end of a critical period, a set of sticky sugar-protein hybrids known as proteoglycans condenses into a tight net around the dendrites and cell bodies of some of the relevant neurons, and in so doing those proteoglycans appear to impede axons that would otherwise be wriggling around as part of the process of readjusting the ocular dominance columns; no wriggling, no learning. In a 2002 study with rats, Italian neuroscientist Tommaso Pizzorusso and his colleagues dissolved the excess proteoglycans with an antiproteoglycan enzyme known as "chABC," and in so doing managed to reopen the critical period. After the chABC treatment, even adult rats could recalibrate their ocular dominance columns. ChABC probably won't help us learn second languages anytime soon, but its antiproteoglycan function may have important medical implications in the not-too-distant future. Another 2002 study, also with rats, showed that chABC can also promote functional recovery after spinal cord injury.

When people’s judgments deviate from a normative model, as they so often do, we have a puzzle to solve. Sometimes the disparity reveals a genuine irrationality: the human brain cannot cope with the complexity of a problem, or it is saddled with a bug that cussedly drives it to the wrong answer time and again. But in many cases there is a method to people’s madness. A problem may have been presented to them in a deceptive format, and when it is translated into a mind-friendlier guise, they solve it. Or the normative model may itself be correct only in a particular environment, and people accurately sense that they are not in that one, so the model doesn’t apply. Or the model may be designed to bring about a certain goal, and, for better or worse, people are after a different one. In the chapters to come, we will see examples of all these extenuating circumstances. The penultimate chapter will lay out how some of today’s florid outbursts of irrationality may be understood as the rational pursuit of goals other than an objective understanding of the world.

Competition is the spice of sports; but if you make spice the whole meal you'll be sick. The simplest single-celled organism oscillates to a number of different frequencies, at the atomic, molecular, sub-cellular, and cellular levels. Microscopic movies of these organisms are striking for the ceaseless, rhythmic pulsation that is revealed. In an organism as complex as a human being, the frequencies of oscillation and the interactions between those frequencies are multitudinous. -George Leonard Learning any new skill involves relatively brief spurts of progress, each of which is followed by a slight decline to a plateau somewhat higher in most cases than that which preceded it…the upward spurts vary; the plateaus have their own dips and rises along the way…To take the master’s journey, you have to practice diligently, striving to hone your skills, to attain new levels of competence. But while doing so–and this is the inexorable–fact of the journey–you also have to be willing to spend most of your time on a plateau, to keep practicing even when you seem to be getting nowhere. (Mastery, p. 14-15). Backsliding is a universal experience. Every one of us resists significant change, no matter whether it’s for the worse or for the better. Our body, brain and behavior have a built-in tendency to stay the same within rather narrow limits, and to snap back when changed…Be aware of the way homeostasis works…Expect resistance and backlash. Realize that when the alarm bells start ringing, it doesn’t necessarily mean you’re sick or crazy or lazy or that you’ve made a bad decision in embarking on the journey of mastery. In fact, you might take these signals as an indication that your life is definitely changing–just what you’ve wanted….Be willing to negotiate with your resistance to change. Our preoccupation with goals, results, and the quick fix has separated us from our own experiences…there are all of those chores that most of us can’t avoid: cleaning, straightening, raking leaves, shopping for groceries, driving the children to various activities, preparing food, washing dishes, washing the car, commuting, performing the routine, repetitive aspects of our jobs….Take driving, for instance. Say you need to drive ten miles to visit a friend. You might consider the trip itself as in-between-time, something to get over with. Or you could take it as an opportunity for the practice of mastery. In that case, you would approach your car in a state of full awareness…Take a moment to walk around the car and check its external condition, especially that of the tires…Open the door and get in the driver’s seat, performing the next series of actions as a ritual: fastening the seatbelt, adjusting the seat and the rearview mirror…As you begin moving, make a silent affirmation that you’ll take responsibility for the space all around your vehicle at all times…We tend to downgrade driving as a skill simply because it’s so common. Actually maneuvering a car through varying conditions of weather, traffic, and road surface calls for an extremely high level of perception, concentration, coordination, and judgement…Driving can be high art…Ultimately, nothing in this life is “commonplace,” nothing is “in between.” The threads that join your every act, your every thought, are infinite. All paths of mastery eventually merge. [Each person has a] vantage point that offers a truth of its own. We are the architects of creation and all things are connected through us. The Universe is continually at its work of restructuring itself at a higher, more complex, more elegant level . . . The intention of the universe is evolution. We exist as a locus of waves that spreads its influence to the ends of space and time. The whole of a thing is contained in each of its parts. We are completely, firmly, absolutely connected with all of existence. We are indeed in relationship to all that is.

Through feedback, said Wiener, Bigelow, and Rosenblueth, a mechanism could embody purpose. Even today, more than half a century later, that assertion still has the power to fascinate and disturb. It arguably marks the beginning of what are now known as artificial intelligence and cognitive science: the study of mind and brain as information processors. But more than that, it does indeed claim to bridge that ancient gulf between body and mind—between ordinary, passive matter and active, purposeful spirit. Consider that humble thermostat again. It definitely embodies a purpose: to keep the room at a constant temperature. And yet there is nothing you can point to and say, "Here it is—this is the psychological state called purpose." Rather, purpose in the thermostat is a property of the system as a whole and how its components are organized. It is a mental state that is invisible and ineffable, yet a natural phenomenon that is perfectly comprehensible. And so it is in the mind, Wiener and his colleagues contended. Obviously, the myriad feedback mechanisms that govern the brain are far more complex than any thermostat. But at base, their operation is the same. If we can understand how ordinary matter in the form of a machine can embody purpose, then we can also begin to understand how those three pounds of ordinary matter inside our skulls can embody purpose—and spirit, and will, and volition. Conversely, if we can see living organisms as (enormously complex) feedback systems actively interacting with their environments, then we can begin to comprehend how the ineffable qualities of mind are not separate from the body but rather inextricably bound up in it.

Imagine you live on a planet where the dominant species is far more intellectually sophisticated than human beings but often keeps humans as companion animals. They are called the Gorns. They communicate with each other via a complex combination of telepathy, eye movements & high-pitched squeaks, all completely unintelligible & unlearnable by humans, whose brains are prepared for verbal language acquisition only. Humans sometimes learn the meaning of individual sounds by repeated association with things of relevance to them. The Gorns & humans bond strongly but there are many Gorn rules that humans must try to assimilate with limited information & usually high stakes. You are one of the lucky humans who lives with the Gorns in their dwelling. Many other humans are chained to small cabanas in the yard or kept in outdoor pens of varying size. They are so socially starved they cannot control their emotions when a Gorn goes near them. The Gorns agree that they could never be House-Humans. The dwelling you share with your Gorn family is filled with water-filled porcelain bowls.Every time you try to urinate in one,nearby Gorn attack you. You learn to only use the toilet when there are no Gorns present. Sometimes they come home & stuff your head down the toilet for no apparent reason. You hate this & start sucking up to the Gorns when they come home to try & stave this off but they view this as evidence of your guilt. You are also punished for watching videos, reading books, talking to other human beings, eating pizza or cheesecake, & writing letters. These are all considered behavior problems by the Gorns. To avoid going crazy, once again you wait until they are not around to try doing anything you wish to do. While they are around, you sit quietly, staring straight ahead. Because they witness this good behavior you are so obviously capable of, they attribute to “spite” the video watching & other transgressions that occur when you are alone. Obviously you resent being left alone, they figure. You are walked several times a day and left crossword puzzle books to do. You have never used them because you hate crosswords; the Gorns think you’re ignoring them out of revenge. Worst of all, you like them. They are, after all, often nice to you. But when you smile at them, they punish you, likewise for shaking hands. If you apologize they punish you again. You have not seen another human since you were a small child. When you see one you are curious, excited & afraid. You really don’t know how to act. So, the Gorn you live with keeps you away from other humans. Your social skills never develop. Finally, you are brought to “training” school. A large part of the training consists of having your air briefly cut off by a metal chain around your neck. They are sure you understand every squeak & telepathic communication they make because sometimes you get it right. You are guessing & hate the training. You feel pretty stressed out a lot of the time. One day, you see a Gorn approaching with the training collar in hand. You have PMS, a sore neck & you just don’t feel up to the baffling coercion about to ensue. You tell them in your sternest voice to please leave you alone & go away. The Gorns are shocked by this unprovoked aggressive behavior. They thought you had a good temperament. They put you in one of their vehicles & take you for a drive. You watch the attractive planetary landscape going by & wonder where you are going. You are led into a building filled with the smell of human sweat & excrement. Humans are everywhere in small cages. Some are nervous, some depressed, most watch the goings on on from their prisons. Your Gorns, with whom you have lived your entire life, hand you over to strangers who drag you to a small room. You are terrified & yell for your Gorn family to help you. They turn & walk away.You are held down & given a lethal injection. It is, after all, the humane way to do it.

So it was that the Red Tower put into production its terrible and perplexing line of unique novelty items. Among the objects and constructions now manufactured were several of an almost innocent nature. These included tiny, delicate cameos that were heavier than their size would suggest, far heavier, and lockets whose shiny outer surface flipped open to reveal a black reverberant abyss inside, a deep blackness roaring with echoes. Along the same lines was a series of lifelike replicas of internal organs and physiological structures, many of them evidencing an advanced stage of disease and all of them displeasingly warm and soft to the touch. There was a fake disembodied hand on which fingernails would grow several inches overnight, every night like clockwork. Numerous natural objects, mostly bulbous gourds, were designed to produce a long deafening scream whenever they were picked up or otherwise disturbed in their vegetable stillness. Less scrutable were such things as hardened globs of lava into whose rough igneous forms were set a pair of rheumy eyes that perpetually shifted their gaze from side to side like a relentless pendulum. And there was also a humble piece of cement, a fragment broken away from any street or sidewalk, that left a most intractable stain, greasy and green, on whatever surface it was placed. But such fairly simple items were eventually followed, and ultimately replaced, by more articulated objects and constructions. One example of this complex type of novelty item was an ornate music box that, when opened, emitted a brief gurgling or sucking sound in emulation of a dying individual's death rattle. Another product manufactured in great quantity at the Red Tower was a pocket watch in gold casing which opened to reveal a curious timepiece whose numerals were represented by tiny quivering insects while the circling "hands" were reptilian tongues, slender and pink. But these examples hardly begin to hint at the range of goods that came from the factory during its novelty phase of production. I should at least mention the exotic carpets woven with intricate abstract patterns that, when focused upon for a certain length of time, composed themselves into fleeting phantasmagoric scenes of the kind which might pass through a fever-stricken or even permanently damaged brain.

In 1976, a doctoral student at the University of Nottingham in England demonstrated that randomizing letters in the middle of words had no effect on the ability of readers to understand sentences. In tihs setncene, for emalxpe, ervey scarbelmd wrod rmenias bcilasaly leibgle. Why? Because we are deeply accustomed to seeing letters arranged in certain patterns. Because the eye is in a rush, and the brain, eager to locate meaning, makes assumptions. This is true of phrases, too. An author writes “crack of dawn” or “sidelong glance” or “crystal clear” and the reader’s eye continues on, at ease with combinations of words it has encountered innumerable times before. But does the reader, or the writer, actually expend the energy to see what is cracking at dawn or what is clear about a crystal? The mind craves ease; it encourages the senses to recognize symbols, to gloss. It makes maps of our kitchen drawers and neighborhood streets; it fashions a sort of algebra out of life. And this is useful, even essential—X is the route to work, Y is the heft and feel of a nickel between your fingers. Without habit, the beauty of the world would overwhelm us. We’d pass out every time we saw—actually saw—a flower. Imagine if we only got to see a cumulonimbus cloud or Cassiopeia or a snowfall once a century: there’d be pandemonium in the streets. People would lie by the thousands in the fields on their backs. We need habit to get through a day, to get to work, to feed our children. But habit is dangerous, too. The act of seeing can quickly become unconscious and automatic. The eye sees something—gray-brown bark, say, fissured into broad, vertical plates—and the brain spits out tree trunk and the eye moves on. But did I really take the time to see the tree? I glimpse hazel hair, high cheekbones, a field of freckles, and I think Shauna. But did I take the time to see my wife? “Habitualization,” a Russian army-commissar-turned-literary-critic named Viktor Shklovsky wrote in 1917, “devours works, clothes, furniture, one’s wife, and the fear of war.” What he argued is that, over time, we stop perceiving familiar things—words, friends, apartments—as they truly are. To eat a banana for the thousandth time is nothing like eating a banana for the first time. To have sex with somebody for the thousandth time is nothing like having sex with that person for the first time. The easier an experience, or the more entrenched, or the more familiar, the fainter our sensation of it becomes. This is true of chocolate and marriages and hometowns and narrative structures. Complexities wane, miracles become unremarkable, and if we’re not careful, pretty soon we’re gazing out at our lives as if through a burlap sack. In the Tom Andrews Studio I open my journal and stare out at the trunk of the umbrella pine and do my best to fight off the atrophy that comes from seeing things too frequently. I try to shape a few sentences around this tiny corner of Rome; I try to force my eye to slow down. A good journal entry—like a good song, or sketch, or photograph—ought to break up the habitual and lift away the film that forms over the eye, the finger, the tongue, the heart. A good journal entry ought be a love letter to the world. Leave home, leave the country, leave the familiar. Only then can routine experience—buying bread, eating vegetables, even saying hello—become new all over again.

Sound waves, regardless of their frequency or intensity, can only be detected by the Mole Fly’s acute sense of smell—it is a little known fact that the Mole Fly’s auditory receptors do not, in fact, have a corresponding center in the brain designated for the purposes of processing sensory stimuli and so, these stimuli, instead of being siphoned out as noise, bypass the filters to be translated, oddly enough, by the part of the brain that processes smell. Consequently, the Mole Fly’s brain, in its inevitable confusion, understands sound as an aroma, rendering the boundary line between the auditory and olfactory sense indistinguishable. Sounds, thus, come in a variety of scents with an intensity proportional to its frequency. Sounds of shorter wavelength, for example, are particularly pungent. What results is a species of creature that cannot conceptualize the possibility that sound and smell are separate entities, despite its ability to discriminate between the exactitudes of pitch, timbre, tone, scent, and flavor to an alarming degree of precision. Yet, despite this ability to hyper-analyze, they lack the cognitive skill to laterally link successions of either sound or smell into a meaningful context, resulting in the equivalent of a data overflow. And this may be the most defining element of the Mole Fly’s behavior: a blatant disregard for the context of perception, in favor of analyzing those remote and diminutive properties that distinguish one element from another. While sensory continuity seems logical to their visual perception, as things are subject to change from moment-to-moment, such is not the case with their olfactory sense, as delays in sensing new smells are granted a degree of normality by the brain. Thus, the Mole Fly’s olfactory-auditory complex seems to be deprived of the sensory continuity otherwise afforded in the auditory senses of other species. And so, instead of sensing aromas and sounds continuously over a period of time—for example, instead of sensing them 24-30 times per second, as would be the case with their visual perception—they tend to process changes in sound and smell much more slowly, thereby preventing them from effectively plotting the variations thereof into an array or any kind of meaningful framework that would allow the information provided by their olfactory and auditory stimuli to be lasting in their usefulness. The Mole flies, themselves, being the structurally-obsessed and compulsive creatures that they are, in all their habitual collecting, organizing, and re-organizing of found objects into mammoth installations of optimal functional value, are remarkably easy to control, especially as they are given to a rather false and arbitrary sense of hierarchy, ascribing positions—that are otherwise trivial, yet necessarily mundane if only to obscure their true purpose—with an unfathomable amount of honor, to the logical extreme that the few chosen to serve in their most esteemed ranks are imbued with a kind of obligatory arrogance that begins in the pupal stages and extends indefinitely, as they are further nurtured well into adulthood by a society that infuses its heroes of middle management with an immeasurable sense of importance—a kind of celebrity status recognized by the masses as a living embodiment of their ideals. And yet, despite this culture of celebrity worship and vicarious living, all whims and impulses fall subservient, dropping humbly to the knees—yes, Mole Flies do, in fact, have knees!—before the grace of the merciful Queen, who is, in actuality, just a puppet dictator installed by the Melic papacy, using an old recycled Damsel fly-fishing lure. The dummy is crude, but convincing, as the Mole flies treat it as they would their true-born queen.

OUR ABILITY TO RECOGNIZE FAMILIAR THINGS At first glance our ability to recognize familiar things may not seem so unusual, but brain researchers have long realized it is quite a complex ability. For example, the absolute certainty we feel when we spot a familiar face in a crowd of several hundred people is not just a subjective emotion, but appears to be caused by an extremely fast and reliable form of information processing in our brain. In a 1970 article in the British science magazine Nature, physicist Pieter van Heerden proposed that a type of holography known as recognition holography offers a way of understanding this ability. * In recognition holography a holographic image of an object is recorded in the usual manner, save that the laser beam is bounced off a special kind of mirror known as a focusing mirror before it is allowed to strike the unexposed film. If a second object, similar but not identical * Van Heerden, a researcher at the Polaroid Research Laboratories in Cambridge, Massachusetts, actually proposed his own version of a holographic theory of memory in 1963, but his work went relatively unnoticed. to the first, is bathed in laser light and the light is bounced off the mirror and onto the film after it has been developed, a bright point of light will appear on the film. The brighter and sharper the point of light the greater the degree of similarity between the first and second objects. If the two objects are completely dissimilar, no point of light will appear. By placing a light-sensitive photocell behind the holographic film, one can actually use the setup as a mechanical recognition system.7 A similar technique known as interference holography may also explain how we can recognize both the familiar and unfamiliar features of an image such as the face of someone we have not seen for many years. In this technique an object is viewed through a piece of holographic film containing its image. When this is done, any feature of the object that has changed since its image was originally recorded will reflect light differently. An individual looking through the film is instantly aware of both how the object has changed and how it has remained the same. The technique is so sensitive that even the pressure of a finger on a block of granite shows up immediately, and the process has been found to have practical applications in the materials testing industry.
