I sat in the dark and thought: There’s no big apocalypse. Just an endless procession of little ones.
Neil Gaiman (Signal to Noise)
Intelligence is the capacity to receive, decode and transmit information efficiently. Stupidity is blockage of this process at any point. Bigotry, ideologies etc. block the ability to receive; robotic reality-tunnels block the ability to decode or integrate new signals; censorship blocks transmission.
Robert Anton Wilson
Whoever fights monsters should see to it that in the process he does not become a monster.
Gavin de Becker (The Gift of Fear: Survival Signals That Protect Us from Violence)
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.
Thomas Metzinger (The Ego Tunnel: The Science of the Mind and the Myth of the Self)
If they had had a different neighbour, one less self-absorbed and more concerned for others, a man of normal, charitable instincts, their desperate state would not have gone unnoticed, their distress-signals would have been heard, and perhaps they would have been rescued by now. Certainly they appeared utterly depraved, corrupt, vile and odious; but it is rare for those who have sunk so low not to be degraded in the process, and there comes a point, moreover, where the unfortunate and the infamous are grouped together, merged in a single fateful word. They are les miserables - the outcasts, the underdogs. And who is to blame? Is it not the most fallen who have most need of charity?
Victor Hugo (Les Misérables)
Of course it’s the apparently tranquil periods that deceive us. Though our instruments or our senses or our wits may not be able to see the processes that are leading toward these clusters of events, they’re happening. The star, the wheel, the butterfly—all are in a subtle state of unrest, waiting for the moment when some invisible mechanism signals that the time has come. Then the star explodes; the wheel makes poor men rich; the butterfly mates and dies.
Clive Barker (Galilee)
You're not a monster,' I said. But I lied. What I really wanted to say was that a monster is not such a terrible thing to be. From the Latin root monstrum, a divine messenger of catastrophe, then adapted by the Old French to mean an animal of myriad origins: centaur, griffin, satyr. To be a monster is to be a hybrid signal, a lighthouse: both shelter and warning at once. I read that parents suffering from PTSD are more likely to hit their children. Perhaps there is a monstrous origin to it, after all. Perhaps to lay hands on your child is to prepare him for war. To say processing a heartbeat is never as simple as the heart's task of saying yes yes yes to the body.
Ocean Vuong (On Earth We're Briefly Gorgeous)
Not merely hope, but any burdensome yearning: ambition, hatred, love (especially love) - how rarely do our emotions meet the object they seem to deserve? How hopelessly we signal; how dark the sky; how big the waves. We are all lost at see, washed between hope and despair, hailing something that may never come to rescue us. Catastrophe has become art; but this is no reducing process. It is freeing, enlarging, explaining. Catastrophe has become art: that is, after all, what it is for.
Julian Barnes (A History of the World in 10½ Chapters)
Our brains turn into simple signal-processing units, quickly shepherding information into consciousness and then back out again.
Nicholas Carr (The Shallows: What the Internet Is Doing to Our Brains)
The theory of economic shock therapy relies in part on the roleof expectations on feeding an inflationary process. Reining in inflation requires not only changing monetary policy but also changing the behavior of consumers, employers and workers. The role of a sudden, jarring policy shift is that it quickly alters expectations, signaling to the public that the rules of the game have changed dramatically - prices will not keep rising, nor will wages.
Naomi Klein (The Shock Doctrine: The Rise of Disaster Capitalism)
Those who favor a “grand plan” over experimentation fail to understand the role that failed experiments play in creating progress in society. Failures quickly and efficiently signal what doesn’t work, minimizing waste and redirecting scarce resources to what does work. A market economy is an experimental discovery process, in which business failures are inevitable and any attempt to eliminate them only ensures even greater failures.
Charles G. Koch (Good Profit: How Creating Value for Others Built One of the World's Most Successful Companies)
Looked at from a spiritual standpoint, our discomfort in any given situation provides a signal that we are out of alignment with spiritual law and are being given an opportunity to heal something.
Colin C. Tipping (Radical Forgiveness: A Revolutionary Five-Stage Process to Heal Relationships, Let Go of Anger and Blame, and Find Peace in Any Situation)
Since Pawlow and his pupils have succeeded in causing the secretion of saliva in the dog by means of optic and acoustic signals, it no longer seems strange to us that what the philosopher terms an 'idea' is a process which can cause chemical changes in the body.
Jacques Loeb (The Mechanistic Conception of Life (The John Harvard Library))
We face danger whenever information growth outpaces our understanding of how to process it. The last forty years of human history imply that it can still take a long time to translate information into useful knowledge, and that if we are not careful, we may take a step back in the meantime.
Nate Silver (The Signal and the Noise: Why So Many Predictions Fail-but Some Don't)
Long before we had writing or farms or post-digital strike helicopters, we had each other. We lived together and changed each other, and so we needed to say “this is who I am, this is what I do.” So, in the same way that we attached sounds to meanings to make language, we began to attach clusters of behavior to signal social roles. Those clusters were rich, and quick-changing, and so just like language, we needed networks devoted to processing them. We needed a place in the brain to construct and to analyze gender.
Isabel Fall
We might think of flavour as frivolous, but there’s a school of thought that says artificial flavouring is the problem when it comes to obesity and overconsumption. Since I did my diet, it’s the word ‘flavouring’ that I avoid more than any other in food. Flavourings signal that something is UPF, and the need for flavouring tells us a lot about some of the ways UPF does us harm.
Chris van Tulleken (Ultra-Processed People: The Science Behind Food That Isn't Food)
For Adamatzky, the point of fungal computers is not to replace silicon chips. Fungal reactions are too slow for that. Rather, he thinks humans could use mycelium growing in an ecosystem as a “large-scale environmental sensor.” Fungal networks, he reasons, are monitoring a large number of data streams as part of their everyday existence. If we could plug into mycelial networks and interpret the signals they use to process information, we could learn more about what was happening in an ecosystem.
Merlin Sheldrake (Entangled Life: How Fungi Make Our Worlds, Change Our Minds & Shape Our Futures)
If they had had a different neighbour, one less sel-absorbed and more concerned for others, a man of normal, charitable instincts, their desperate state would not have gone unnoticed, their distress-signals would have been heard, and perhaps they would have been rescued by now. Certainly they appeared utterly depraved, corrupt, vile and odious; but it is rare for those who have sunk so low not to be degraded in the process, and there comes a point, moreover, where the unfortunate and the infamous are grouped together, merged in a single, fateful world. They are les misérables - the outcasts, the underdogs. And who is to blame? Is it not the most fallen who have most need for charity?
Victor Hugo (Les Misérables)
The conscious or unconscious decision to use violence, or to do most anything, involves many mental and emotional processes, but they usually boil down to how a person perceives four fairly simple issues: justification, alternatives, consequences, and ability.
Gavin de Becker (The Gift of Fear: Survival Signals That Protect Us from Violence)
High-purpose environments are filled with small, vivid signals designed to create a link between the present moment and a future ideal. They provide the two simple locators that every navigation process requires: Here is where we are and Here is where we want to
Daniel Coyle (The Culture Code: The Secrets of Highly Successful Groups)
In all major socializing forces you will find an underlying movement to gain and maintain power through the use of words. From witch doctor to priest to bureaucrat it is all the same. A governed populace must be conditioned to accept power-words as actual things to confuse the symbolized system with the tangible universe. In the maintenance of such a power structure, certain symbols are kept out of the reach of common understanding—symbols such as those dealing with economic manipulation or those which define the local interpretation of sanity. Symbol-secrecy of this form leads to the development of fragmented sub-languages, each being a signal that its users are accumulating some form of power. With this insight into a power process, our Imperial Security Force must be ever alert to the formation of sub-languages.
Frank Herbert (Children of Dune (Dune #3))
Ironically, the better we map this process, the harder it becomes to explain conscious feelings. The better we understand the brain, the more redundant the mind seems. If the entire system works by electric signals passing from here to there, why the hell do we also need to feel fear?
Yuval Noah Harari (Homo Deus: A Brief History of Tomorrow)
The boredom will go away once you enter the cycle. The panic disappears after repeated exposure. The frustration is a sign of progress—a signal that your mind is processing complexity and requires more practice. The insecurities will transform into their opposites when you gain mastery.
Robert Greene (Mastery)
The key to making a good forecast, as we observed in chapter 2, is not in limiting yourself to quantitative information. Rather, it’s having a good process for weighing the information appropriately.
Nate Silver (The Signal and the Noise: Why So Many Predictions Fail-but Some Don't)
For people who make up stories for a living, that is the ultimate success: knowing that, when the book closes, when the series ends, the adventure is not over. It goes on without the creator, in the minds of the people who love it. You can’t stop the signal. Once it’s broadcast, it continues on forever, pulsing past star clusters, lighting up new worlds, collecting new fans, till the end of time itself.
Sharon Shinn (Whedonistas: A Celebration of the Worlds of Joss Whedon by the Women Who Love Them)
Nietzsche quote I have often considered: “Whoever fights monsters should see to it that in the process he does not become a monster. For when you look long into an abyss, the abyss also looks into you.”)
Gavin de Becker (The Gift of Fear: Survival Signals That Protect Us from Violence)
Our feelings of anxiety are genuine but confused signals that something is amiss, and so need to be listened to and patiently interpreted -- processes which are unlikely to be completed when we have to hand, in the computer, one of the most powerful tools of distraction ever invented. The entire internet is in a sense pornographic, a deliverer of a constant excitement that we have no innate capacity to resist, a seducer that leads us down paths that for the most part do nothing to answer our real needs.
Alain de Botton (How to Think More About Sex)
The cerebral processing of that visceral input as a signal of death was accurate. Without the kinds of therapy that had been developed over the decades, this cancer would have been fatal. Hope, then, is constructed not just from rational deliberation, from the conscious weighing of information; it arises as an amalgam of thought and feeling, the feelings created in part by neural input from the organs and tissues.
Jerome Groopman (The Anatomy of Hope: How People Prevail in the Face of Illness)
Companies come up with elaborate, often passive-aggressive ways to say no: processes to follow, approvals to get, meetings to attend. No is like a tiny death to smart creatives. No is a signal that the company has lost its start-up verve, that it’s too corporate. Enough no’s, and smart creatives stop asking and start heading to the exits.
Eric Schmidt (How Google Works)
Many experts lose the creativity and imagination of the less informed. They are so intimately familiar with known patterns that they may fail to recognize or respect the importance of the new wrinkle. The process of applying expertise is, after all, the editing out of unimportant details in favor of those known to be relevant. Zen master, Shunryu Suzuki said, “The mind of the beginner is empty, free of the habits of the expert, ready to accept, to doubt, and open to all the possibilities.
Gavin de Becker (The Gift of Fear: Survival Signals That Protect Us from Violence)
feel an emotion it is necessary but not sufficient that neural signals from viscera, from muscles and joints, and from neurotransmitter nuclei—all of which are activated during the process of emotion—reach certain subcortical nuclei and the cerebral cortex. Endocrine and other chemical signals also reach the central nervous system via the bloodstream among other routes.
António R. Damásio (Descartes' Error: Emotion, Reason and the Human Brain)
But remember, anger cannot be fought with anger. Rage cannot be fought with rage. No amount of signal processing can cancel out suffering, or craving, or aversion. If you want to help a mind – or a world – find peace, do exactly that. Help it find peace.
Ramez Naam (Apex (Nexus, #3))
So as you prepared to enter into the planetary relationship, you created beings to represent your original state of unified awareness. These are the angels. Their value, as well as their limitation, springs from the fact that they have no comprehension of the process you are undertaking. Their instructions were to pretty much stay out of things until near the very end of the process. Then, upon receipt of a pre-arranged signal, they were to commune with the human beings on Earth at that time and assist them in awakening to their original state of unified consciousness.
Ken Carey (The Starseed Transmissions)
fat cells much more than passive storage sites for excess calories. Fat cells take in or release calories only when instructed to do so by external signals—and the master control is insulin. Too much insulin causes weight gain, whereas too little causes weight loss. So if we think about obesity as a disorder involving fat cells, then a radically different view emerges: Overeating doesn’t make us fat. The process of becoming fat makes us overeat.
David Ludwig (Always Hungry?: Conquer cravings, retrain your fat cells and lose weight permanently)
I feel it is part of the mystery of faith that things normally do not line up entirely, and so when they don’t, it is not a signal to me that the journey is at an end but that I am still on it. As I reflect on my own experience and that of many others far wiser than I, God seems willing to help that process along.
Peter Enns (The Sin of Certainty: Why God Desires Our Trust More Than Our "Correct" Beliefs)
It is better that we gain what we demand by a process of negotiation which would occupy twenty years, than that by communicating a sudden shock to the interests of those who are the depositaries and dependents of power we should incur the calamity which their revenge might inflict upon us by giving the signal of . . . war.
Percy Bysshe Shelley (The Major Works)
Consider that at any given moment, our five senses are taking in more than 11,000,000 pieces of information. Scientists have determined this number by counting the receptor cells each sense organ has and the nerves that go from these cells to the brain. Our eyes alone receive and send over 10,000,000 signals to our brains each second. Scientists have also tried to determine how many of these signals can be processed consciously at any given point in time, by looking at such things as how quickly people can read, consciously detect different flashes of light, and tell apart different kinds of smells. The most liberal estimate is that people can process consciously about 40 pieces of information per second.
Timothy D. Wilson (Strangers to Ourselves: Discovering the Adaptive Unconscious)
We face danger whenever information growth outpaces our understanding of how to process it.
Nate Silver (The Signal and the Noise: Why So Many Predictions Fail-but Some Don't)
sometimes the only solution when the data is very noisy—is to focus more on process than on results.
Nate Silver (The Signal and the Noise: Why So Many Predictions Fail-but Some Don't)
Researchers have concluded two things. One is that we drop out of conversations every twelve to eighteen seconds to process what people are saying; two, we often remember what we think about what another person is saying because that is a stronger internal process and chemical signal. In other words, our internal listening and dialogue trumps the other person’s speech.
Judith E. Glaser (Conversational Intelligence: How Great Leaders Build Trust & Get Extraordinary Results)
When you’re truly focused on an intention for some future outcome, if you can make inner thought more real than the outer environment during the process, the brain won’t know the difference between the two. Then your body, as the unconscious mind, will begin to experience the new future event in the present moment. You’ll signal new genes, in new ways, to prepare for this imagined future event.
Joe Dispenza (You Are the Placebo: Making Your Mind Matter)
Looked at from a spiritual standpoint, our discomfort in any given situation provides a signal that we are out of alignment with spiritual law and are being given an opportunity to heal something. It
Colin C. Tipping (Radical Forgiveness: A Revolutionary Five-Stage Process to Heal Relationships, Let Go of Anger and Blame, and Find Peace in Any Situation)
The brain’s auditory cortex, for instance, processes an audio signal from your ear faster than a visual signal is processed in the visual cortex. The difference is around 40 milliseconds, which is not much, but enough to justify using a gun for starting a race, instead of a light flash. The faster audio processing speed means that sprint runners react more quickly to a bang than to a flash of light.
Jean Paul Zogby (The Power of Time Perception)
Even in utero and after birth, for every moment of every day, our brain is processing the nonstop set of incoming signals from our senses. Sight, sound, touch, smell, taste—all of the raw sensory data that will result in these sensations enter the lower parts of the brain and begin a multistage process of being categorized, compared to previously stored patterns, and ultimately, if necessary, acted upon. In many cases the pattern of incoming signals is so repetitive, so familiar, so safe and the memory template that this pattern matches is so deeply engrained, that your brain essentially ignores them. This is a form of tolerance called habituation.
Bruce D. Perry (The Boy Who Was Raised As a Dog: And Other Stories from a Child Psychiatrist's Notebook)
Most people don't see half of what's in front of them. Your visual cortex does a shit load of imaging processing before the signal even gets to your brain, whose priorities are still checking the ancestral Savannah for dangerous predators, edible berries and climable trees. That's why a sudden cat in the night can make you jump and some people when distracted, can walk right out in front of a bus. Your brain just isn't interested in those large moving chunks of metal or the static heaps of brightly colored stuff that piles up in drifts around us. Never mind all that, says your brain, it's those silent fur-covered merchants of death you've got to watch out for.
Ben Aaronovitch (Broken Homes (Peter Grant, #4))
When it comes to mastering a skill, time is the magic ingredient. Assuming your practice proceeds at a steady level, over days and weeks certain elements of the skill become hardwired. Slowly, the entire skill becomes internalized, part of your nervous system. The mind is no longer mired in the details, but can see the larger picture. It is a miraculous sensation and practice will lead you to that point, no matter the talent level you are born with. The only real impediment to this is yourself and your emotions—boredom, panic, frustration, insecurity. You cannot suppress such emotions—they are normal to the process and are experienced by everyone, including Masters. What you can do is have faith in the process. The boredom will go away once you enter the cycle. The panic disappears after repeated exposure. The frustration is a sign of progress—a signal that your mind is processing complexity and requires more practice. The insecurities will transform into their opposites when you gain mastery. Trusting this will all happen, you will allow the natural learning process to move forward, and everything else will fall into place.
Robert Greene (Mastery (The Modern Machiavellian Robert Greene Book 1))
Many believe the process of creativity is one of assembling thoughts and concepts, but highly creative people will tell you that the idea, the song, the image, was in them, and their task was to get it out, a process of discovery, not design. This
Gavin de Becker (The Gift of Fear: Survival Signals That Protect Us from Violence)
Futurists are skilled at listening to and interpreting the signals talking. It’s a learnable skill, and a process anyone can master. Futurists look for early patterns—pre-trends, if you will—as the scattered points on the fringe converge and begin moving toward the mainstream. They know most patterns will come to nothing, and so they watch and wait and test the patterns to find those few that will evolve into genuine trends. Each trend is a looking glass into the future, a way to see over time’s horizon. The advantage of forecasting the future in this way is obvious. Organizations that can see trends early enough to take action have first-mover influence. But they can also help to inform and shape the broader context, conversing and collaborating with those in other fields to plan ahead.
Amy Webb (The Signals Are Talking: Why Today's Fringe Is Tomorrow's Mainstream)
I became aware of Jews in my early teens, as I started to pick up the signals from the Christian church. Not that I was Christian – I’d been an atheist since I was five. But my father, a Congregational minister, had some sympathy with the idea that the Jews had killed Christ. But any indoctrination was offset by my discovery of the concentration camps, of the Final Solution. Whilst the term 'Holocaust' had yet to enter the vocabulary I was overwhelmed by my realisation of what Germany had perpetrated on Jews. It became a major factor in my movement towards the political left. I’d already read 'The Grapes of Wrath' by John Steinbeck, the Penguin paperback that would change my life. The story of the gas chambers completed the process of radicalisation and would, just three years later, lead me to join the Communist Party.
Phillip Adams
To the contrary, they frequently desire only relief from the symptoms of their depression “so that things can be as they used to be.” They do not know that things can no longer be “the way they used to be.” But the unconscious knows. It is precisely because the unconscious in its wisdom knows that “the way things used to be” is no longer tenable or constructive that the process of growing and giving up is begun on an unconscious level and depression is experienced. As likely as not the patient will report, “I have no idea why I’m depressed” or will ascribe the depression to irrelevant factors. Since patients are not yet consciously willing or ready to recognize that the “old self” and “the way things used to be” are outdated, they are not aware that their depression is signaling that major change is required for successful and evolutionary adaptation. The

As he analyzed the areas that fire in chronic pain, he observed that many of those areas also process thoughts, sensations, images, memories, movements, emotions, and beliefs—when they are not processing pain. That observation explained why, when we are in pain, we can’t concentrate or think well; why we have sensory problems and often can’t tolerate certain sounds or light; why we can’t move more gracefully; and why we can’t control our emotions very well and become irritable and have emotional outbursts. The areas that regulate these activities have been hijacked to process the pain signal.
Norman Doidge (The Brain's Way of Healing: Remarkable Discoveries and Recoveries from the Frontiers of Neuroplasticity)
This gesture is one of the motifs of modernity's turn against the principle of imitating nature, that is to say, imitating predefined morphological expectations. It is still capable of perceiving message-totalities and autonomous thing-signals when no morphologically intact figures are left - indeed, precisely then. The sense for perfection withdraws from the forms of nature - probably because nature itself is in the process of losing its ontological authority. The popularization of photography also increasingly devalues the standard views of things. As the first edition of the visible, nature comes into discredit. It can no longer assert its authority as the sender of binding messages - for reasons that ultimately come from its disenchantment through being scientifically explored and technically outdone. After this shift, 'being perfect' takes on an altered meaning: it means having something to say that is more meaningful than the chatter of conventional totalities. Now the torsos and their ilk have their turn: the hour of those forms that do not remind us of anything has come. Fragments, cripples and hybrids formulate something that cannot be conveyed by the common whole forms and happy integrities; intensity beats standard perfection.
Peter Sloterdijk (Du mußt dein Leben ändern)
Mechanical stress on the bone produced a piezoelectric signal from the collagen. The signal was biphasic, switching polarity with each stress-and-release. The signal was rectified by the PN junction between apatite and collagen. This coherent signal did more than merely indicate that stress had occurred. Its strength told the cells how strong the stress was,and its polarity told them what direction it came from. Osteogenic cells where the potential was negative would be stimulated to grow more bone, while those in the positive area would close up shop and dismantle their matrix. If growth and resorption were considered as two aspects of one process, the electrical signal acted as an analog code to transfer information about stress to the cells and trigger the appropriate response.Now we knew how stress was converted into an electrical signal. We had discovered a transducer, a device that converts other forces into electricity or vice versa.
Robert O. Becker (The Body Electric: Electromagnetism and the Foundation of Life)
So, let's get back to why the roots are the most important part of a tree. Conceivably, this is where the tree equivalent of a brain is located. Brain? you ask. Isn't that a bit farfetched? Possibly, but now we know that trees can learn. This means they must store experiences somewhere, and therefore, there must be some kind of a storage mechanism inside the organism. Just where it is, no one knows, but the roots are the part of the tree best suited to the task. The old spruce in Sweden also shows that what grows underground is the most permanent part of the tree-and where else would it store important information over a long period of time? Moreover, current research shows that a tree's delicate root networks is full of surprises. It is now an accepted fact that the root network is in charge of all chemical activity in the tree. And there's nothing earth shattering about that. Many of our internal processes are also regulated by chemical messengers. Roots absorb substances and bring them into the tree. In the other direction, they deliver the products of photosynthesis to the tree's fungal partners and even route warning signals to neighboring trees. But a brain? For there to be something we would recognize as a brain, neurological processes must be involved, and for these, in addition to chemical messages, you need electrical impulses. And these are precisely what we can measure in the tree, and we've been able to do so since as far back as the nineteenth century. For some years now, a heated controversy has flared up among scientists. Can plants think? Are they intelligent?
Peter Wohlleben (The Hidden Life of Trees: What They Feel, How They Communicate: Discoveries from a Secret World)
Alerting, which indicates when to attend, and adapts our level of vigilance. Orienting, which signals what to attend to, and amplifies any object of interest. Executive attention, which decides how to process the attended information, selects the processes that are relevant to a given task, and controls their execution.
Stanislas Dehaene (How We Learn: Why Brains Learn Better Than Any Machine . . . for Now)
But in my experience, there is one way to signal your commitment to process that all negotiations provide: Always keep your word, even when it is costly. The best deal makers and diplomats take very seriously the promises and commitments they have made to the other side on small things and big. This is not only the right thing to do; it is a tremendously powerful instrument in deal making. Especially in difficult, protracted conflicts where negotiating itself might be seen as risky or useless, often the only source of leverage you have for bringing the other side to the table is your credibility. And once you’re at the table, mistrust is often the biggest barrier to the give-and-take necessary for progress, because many of the concessions either side commits to are not deliverable right away—promises of equitable treatment, power sharing, future benefits, etc. are necessarily premised on trust. If you have not built up a reputation for credibility, you are ill-suited to negotiate such deals.
Deepak Malhotra (Negotiating the Impossible: How to Break Deadlocks and Resolve Ugly Conflicts (without Money or Muscle))
To answer a popular question, if we define sound as traveling fluctuations in air pressure, then yes, a tree falling in the woods with no one nearby does indeed make a sound. If we define sound to be the electrical signal transmitted by the mechanisms of our inner ears to our brains, then no, that tree falling in the woods makes no sound.
Richard G. Lyons (Essential Guide to Digital Signal Processing, The (Essential Guide Series))
depending on how much nectar it’s found and how much help it has already recruited, a foraging honeybee flies back to the hive and communicates a status update by waggling figure eights on the walls. These torso wags map the exact location of a food source in relation to the sun, as well as its precise distance from the hive. If there are not enough bees outside the hive to exploit the find, the forager bee adds flourishes such as grabbing a hive mate from above and shaking him all over. Not enough workers in-house to process the flood of incoming nectar? The bee will tremble while moving through the hive “with forelegs held aloft like Saint Vitus dancers,” write the entomologists.

Susan Pinker (The Village Effect: Why Face-to-face Contact Matters)
...because the great beauty of embryo development, the bit that human beings find so hard to grasp, is that it is a totally decentralised process...no cell need wait for instructions from authority; every cell can act on its own information and the signals it receives from its neighbours. We do not organise societies that way...Perhaps we should try.
Matt Ridley
When you walked through a park, the immersive world that surrounded you was something that existed inside your own brain as a pattern of neurons firing. The sensation of a bright blue sky wasn't something high above you, it was something in your visual cortex, and your visual cortex was in the back of your brain. All the sensations of that bright world were really happening in that quiet cave of bone you called your skull, the place where you lived and never, ever left. If you really wanted to say hello to someone, to the actual person, you wouldn't shake their hand, you'd knock gently on their skull and say "How are you doing in there?" That was what people were, that was where they really lived. And the picture of the park that you thought you were walking through was something that was visualized inside your brain as it processed the signals sent down from your eyes and retina. It wasn't a lie like the Buddhists thought, there wasn't something terribly mystical and unexpected behind the veil of Maya, what lay beyond the illusion of the park was just the actual park, but it was all still illusion.
Eliezer Yudkowsky (Harry Potter and the Methods of Rationality)
Be honest with yourself. You were at your lowest and broken down. You were unsure and lost hope. You were hiding your fears until you showed them on your sleeve. You felt like everything and everyone was the hammer and you were the nail as they were beating down on you, and it was never-ending. Their empty threats had you scared and you were always running because your weakness was exposed. You were their prey. You didn’t know who to believe because of their mixed signals. You might not see it now, but you are stronger than you can ever imagine. You cannot become comfortable in your pain. You have to let the pain that you feel turn you into a rose without thorns. There are sixteen pieces on the chessboard. The king is the most important piece, but the difference is that the queen is the most powerful piece! You are a queen, you can maneuver around your opponents; they do not have the power over your life, your mind or soul. You might think you’ve been a prisoner, but that is your past’. Look in the now and work your way to how you want your future to be. Exercise your thoughts into a pattern of letting go, and think positively about more of what you want than what you do not want. Queen! You are a queen! As a matter of fact, you are the queen! Act as if you know it! You are powerful, determined, strong, and you can make the biggest and most extravagant move and put it into action. Lights, camera, strike a pose and own it! It is yours to own! Yes, you loved and loved so much. You also lost as well, but you lost hurt, pain, agony, and confusion. You’ve lost interest in wanting to know answers to unanswered questions. You’ve lost the willingness to give a shit about what others think. You’ve surrendered to being fine, that you cannot change the things you have no control over. You’ve lost a lot, but you’ve gained closure. You are now balanced, centered, focused, and filled with peace surrounding you in your heart, mind, body, and soul. Your pride was hurt, but you would rather walk alone and be more willing to give and learn more about the queen you are. You lost yourself in the process, but the more you learn about the new you, the more you will be so much in love with yourself. The more you learn about the new you, the more you will know your worth. The more you learn about the new you, the happier you are going to be, and this time around you will be smiling inside and out! The dots are now connecting. You feel alive! You know now that all is not lost. Now that you’ve cut the cord it is time to give your heart a second chance at loving yourself. Silence your mind. Take a deep breath and close your eyes. As you open your eyes, look at your reflection in the mirror. Aren’t you beautiful, Queen? Embrace who you are. Smile, laugh, welcome the new you and say, “My world is just now beginning.
Charlena E. Jackson (A Woman's Love Is Never Good Enough)
Every year there was an important poetry contest at the fair of ‘Ukaz, just outside Mecca, and the winning poems were embroidered in gold on fine black cloth and hung on the walls of the Kabah. Muhammad’s followers would, therefore, have been able to pick up verbal signals in the text that are lost in translation. They found that themes, words, phrases, and sound patterns recurred again and again—like the variations in a piece of music, which subtly amplify the original melody, and add layer upon layer of complexity. The Qur’an was deliberately repetitive; its ideas, images, and stories were bound together by these internal echoes, which reinforced its central teaching with instructive shifts of emphasis. They linked passages that initially seemed separate, and integrated the different strands of the text, as one verse delicately qualified and supplemented others. The Qur’an was not imparting factual information that could be conveyed instantaneously. Like Muhammad, listeners had to absorb its teachings slowly; their understanding would grow more profound and mature over time, and the rich, allusive language and rhythms of the Qur’an helped them to slow down their mental processes and enter a different mode of consciousness.
Karen Armstrong (Muhammad: A Prophet for Our Time (Eminent Lives))
Throwing the leg of lamb out the window may have been Aunt Carol's outward expression of the process going on within her soul: the reclaiming of herself. Perhaps it was her way of saying how tired she was of waiting on her family, of signaling to them that she was past the cook/chauffeur/dishwasher stage of life. For many women, if not most, part of this reclamation process includes getting in touch with anger and, perhaps, blowing up at loved ones for the first time.

The symbolic and ritual tools of magical practice can be used to set off the same set of reactions that allow a child, or for that matter a baby baboon, to stock its social self with the nonverbal and emotionally charged patterns of its social group. In a capable initiation ritual, this is done in a careful and controlled way, with patterns that further the process of magical training, and the candidate – the person going through the initiation – is taught nonverbal signals that allow him or her to activate the new patterns when it’s time to use them, and deactivate them when it’s time to deal with the nonmagical world. In the short term, this makes it possible to practice magic without too much psychological strain; in the long term, the experience of shifting from one set of arbitrary social patterns and emotional charges to another teaches the reasoning mind to get some distance from the social self, and think its own thoughts rather than those it has been spoonfed by its society.

At one time I attached some importance to the view that what was used as a discharge of anxiety was the cathexis which had been withdrawn in the process of repression. To-day this seems to me of scarcely any interest. The reason for this is that whereas I formerly believed that anxiety invariably arose automatically by an economic process, my present conception of anxiety as a signal given by the ego in order to affect the pleasure-unpleasure agency does away with the necessity of considering the economic factor.
Sigmund Freud (Inhibitions, Symptoms and Anxiety)
She was coming to look on men and women as fellow survivors; well-dissemblers of their woes, who, with few signals of grief, had contained, assimilated, or just put to use their own destruction. Of those who had endured the worst, not all behaved nobly or consistently. But all, involuntarily, became part of a deeper assertion to life. Though the dissolution of love created no heroes, the process itself required some heroism. There was the risk that endurance might appear enough of an achievement. That risk had come up before.
Shirley Hazzard (The Transit of Venus)
Ideally we need a process of doing our daily work in which we can immerse ourselves completely in our current task without the distraction of the unfinished. When you go to the doctor, you may only get 15 minutes, but if that 15 minutes is truly devoted to your medical needs, you feel attended to. Contrast this with the doctor who juggles several patients at once or sends signals of impatience that make it clear he has mountains of other patients waiting. You sense that they can’t wait for you to leave so the doctor can get on with treating the next person. And the next person gets the same treatment.
Gregg Krech (The Art of Taking Action: Lessons from Japanese Psychology)
In simplest terms, you won’t be able to unlock your creative potential, achieve sustainable success, or even be fundamentally happy unless you align your internal and external worlds—unless you’re true to yourself. Therefore, to begin the journey of discovering your purpose, you must focus on what matters to you internally, not externally. And the first step in this process is to eliminate obstacles that prevent you from hearing the signal above the noise. These obstacles include things such as commercial concerns, financial motivations, comparing yourself to someone else, and other manifestations of ego.
Alan Philips (The Age of Ideas: Unlock Your Creative Potential)
We can begin to understand what this means by taking up the fourth principle: whenever possible, we should take measures to re-embody the information we think about. The pursuit of knowledge has frequently sought to disengage thinking from the body, to elevate ideas to a cerebral sphere separate from our grubby animal anatomy. Research on the extended mind counsels the opposite approach: we should be seeking to draw the body back into the thinking process. That may take the form of allowing our choices to be influenced by our interoceptive signals—a source of guidance we’ve often ignored in our focus on data-driven decisions. It might take the form of enacting, with bodily movements, the academic concepts that have become abstracted, detached from their origin in the physical world. Or it might take the form of attending to our own and others’ gestures, tuning back in to what was humanity’s first language, present long before speech. As we’ve seen from research on embodied cognition, at a deep level the brain still understands abstract concepts in terms of physical action, a fact reflected in the words we use (“reaching for a goal,” “running behind schedule”); we can assist the brain in its efforts by bringing the literal body back into the act of thinking.
Annie Murphy Paul (The Extended Mind: The Power of Thinking Outside the Brain)
which is to say, everyone with a heartbeat. I explained to her that even in the best possible relationship, you’re going to get hurt sometimes, and no matter how much you love somebody, you will at times hurt that person, not because you want to, but because you’re human. You will inevitably hurt your partner, your parents, your children, your closest friend—and they will hurt you—because if you sign up for intimacy, getting hurt is part of the deal. But, I went on, what was so great about a loving intimacy was that there was room for repair. Therapists call this process rupture and repair, and if you had parents who acknowledged their mistakes and took responsibility for them and taught you as a child to acknowledge your mistakes and learn from them too, then ruptures won’t feel so cataclysmic in your adult relationships. If, however, your childhood ruptures didn’t come with loving repairs, it will take some practice for you to tolerate the ruptures, to stop believing that every rupture signals the end, and to trust that even if a relationship doesn’t work out, you will survive that rupture too. You will heal and self-repair and sign up for another relationship full of its own ruptures and repairs. It’s not ideal, opening yourself up like this, putting your shield down, but if you want the rewards of an intimate relationship, there’s no way around it.

We are very apt to think of the ego as powerless against the id; but when it is opposed to an instinctual process in the id it has only to give a ‘signal of unpleasure’ in order to attain its object with the aid of that almost omnipotent institution, the pleasure principle. To take this situation by itself for a moment, we can illustrate it by an example from another field. Let us imagine a country in which a certain small faction objects to a proposed measure the passage of which would have the support of the masses. This minority obtains command of the press and by its help manipulates the supreme arbiter, ‘public opinion’, and so succeeds in preventing the measure from being passed.
Sigmund Freud (Inhibitions, Symptoms and Anxiety)
There were other strange signals and signs. Another day, suddenly felt an almost overwhelming urge to travel to Balitmore. I wanted to 'kidnap' a helicoper fly it there if I didn't drive the there', she explains. 'I had no idea where I was to go, only that I was certain I would know my destination as I encountered signs and certain landmarks along the way. I was not even certain who I was to meet, or what my mission was, but I felt I must go.' Beginning to heal by this time with Talbon's help, she resisted that urge. Yet she sensed she would be summoned for three more Cat Woman missions: two in 1999 and one in 2000. As for the code words for activating her, those had been erased from Cheryl's conscious memory. Buried deep in her unconscious mind, however, the words, when called up, cause her to react as her programmers want her to. Though she can't remember the activation codes, Cheryl knows her handlers said the same things every time. 'I'm working on unblocking the words in therapy. Once I know what the words are, I can learn how to stop their effect on me. I did it already when I learned the control code. Standing in front of a mirror, I said the control code words over and over until I was completely desensitised to them. That's what I have to do for the activation code words... but I have not been able to recall all of them as yet.' Dr. Talbon was struck by another very important thing. 'It all hung together. The stories Cheryl told - even though it was upsetting to think people could do stuff like that - they were not disjointed. They were not repetitive in terms of "I've heard this before". It was not just trying consciously or unconsciously to get attention. She'd really processed them out and was done with them. She didn't come up with it again [after telling the story once and dealing with it]. Once it was done, it was done. And I think that was probably the biggest factor for me in her believability. I got no sense that she was using these stories to make herself a really interesting person to me so I'd really want to work with her, or something.
Cheryl Hersha (Secret Weapons: How Two Sisters Were Brainwashed to Kill for Their Country)
Language is a social energy, and our capacity for articulate speech is the key factor that makes us different from other species. We are not as fast as cheetahs – or even as horses. Nor are we as strong as bulls or as adaptable as bacteria. But our brains are equipped with the facility to produce and process speech, and we are capable of abstract thought. A bee may dance to show other bees the location of a source of food, a green monkey may deliver sophisticated vocal signals, and a sparrow may manage as many as thirteen different types of song, but an animal's system of communication has a limited repertoire; ours, on the other hand, is 'open', and its mechanisms permit a potentially infinite variety of utterances.
Henry Hitchings (The Secret Life of Words: How English Became English)
Why two (or whole groups) of people can come up with the same story or idea at the same time, even when across the world from each-other: "A field is a region of influence, where a force will influence objects at a distance with nothing in between. We and our universe live in a Quantum sea of light. Scientists have found that the real currency of the universe is an exchange of energy. Life radiates light, even when grown in the dark. Creation takes place amidst a background sea of energy, which metaphysics might call the Force, and scientists call the "Field." (Officially the Zero Point Field) There is no empty space, even the darkest empty space is actually a cauldron of energies. Matter is simply concentrations of this energy (particles are just little knots of energy.) All life is energy (light) interacting. The universe is self-regenreating and eternal, constantly refreshing itself and in touch with every other part of itself instantaneously. Everything in it is giving, exchanging and interacting with energy, coming in and out of existence at every level. The self has a field of influence on the world and visa versa based on this energy. Biology has more and more been determined a quantum process, and consciousness as well, functions at the quantum level (connected to a universe of energy that underlies and connects everything). Scientist Walter Schempp's showed that long and short term memory is stored not in our brain but in this "Field" of energy or light that pervades and creates the universe and world we live in. A number of scientists since him would go on to argue that the brain is simply the retrieval and read-out mechanism of the ultimate storage medium - the Field. Associates from Japan would hypothesize that what we think of as memory is simply a coherent emission of signals from the "Field," and that longer memories are a structured grouping of this wave information. If this were true, it would explain why one tiny association often triggers a riot of sights, sounds and smells. It would also explain why, with long-term memory in particular, recall is instantaneous and doesn't require any scanning mechanism to sift through years and years of memory. If they are correct, our brain is not a storage medium but a receiving mechanism in every sense, and memory is simply a distant cousin of perception. Some scientists went as far as to suggest that all of our higher cognitive processes result from an interaction with the Field. This kind of constant interaction might account for intuition or creativity - and how ideas come to us in bursts of insight, sometimes in fragments but often as a miraculous whole. An intuitive leap might simply be a sudden coalescence of coherence in the Field. The fact that the human body was exchanging information with a mutable field of quantum fluctuation suggested something profound about the world. It hinted at human capabilities for knowledge and communication far deeper and more extended than we presently understand. It also blurred the boundary lines of our individuality - our very sense of separateness. If living things boil down to charged particles interacting with a Field and sending out and receiving quantum information, where did we end and the rest of the world began? Where was consciousness-encased inside our bodies or out there in the Field? Indeed, there was no more 'out there' if we and the rest of the world were so intrinsically interconnected. In ignoring the effect of the "Field" modern physicists set mankind back, by eliminating the possibility of interconnectedness and obscuring a scientific explanation for many kinds of miracles. In re-normalizing their equations (to leave this part out) what they'd been doing was a little like subtracting God.
Lynne McTaggart (The Field)
In Molecules of Emotion, Pert revealed how her study of information-processing receptors on nerve cell membranes led her to discover that the same “neural” receptors were present on most, if not all, of the body’s cells. Her elegant experiments established that the “mind” was not focused in the head but was distributed via signal molecules to the whole body. As importantly, her work emphasized that emotions were not only derived through a feedback of the body’s environmental information. Through self-consciousness, the mind can use the brain to generate “molecules of emotion” and override the system. While proper use of consciousness can bring health to an ailing body, inappropriate unconscious control of emotions can easily make a healthy body diseased,

Most journals are repositories of great swatches of abstraction and generalization and self-analysis and interpretation and all that bad stuff. Don’t do that. But here’s a certain kind of journal that might be useful to you: at the end of the day or beginning of the next day, return to some event of the day that evoked an emotion in you. Record that event in the journal. But do this only—only—moment to moment through the senses. Absolutely never name an emotion; never start explaining or analyzing or interpreting an emotion. Record only through those five ways I mentioned that we feel emotions—signals inside the body, signals outside the body, flashes of the past, flashes of the future, sensual selectivity—which are therefore the best ways to express emotions.

A system which looks to the extinction of a race is too abhorrent for a Nation to indulge in,” Grant told Congress in his first annual message in December 1869. As with all his presidential addresses, he composed it himself. “I see no remedy for this except in placing all the Indians on large reservations, as rapidly as it can be done, and giving them absolute protection there.”26 This hopeful, idealistic path, paved with good intentions, had been touted by well-meaning presidents from George Washington to Abraham Lincoln. Grant saw absorption and assimilation as a benign, peaceful process, not one robbing Indians of their rightful culture. Whatever its shortcomings, Grant’s approach seemed to signal a remarkable advance over the ruthless methods adopted by some earlier administrations.

This is the science behind how UPF affects the human body: • The destruction of the food matrix by physical, chemical and thermal processing means that UPF is, in general, soft. This means you eat it fast, which means you eat far more calories per minute and don’t feel full until long after you’ve finished. It also potentially reduces facial bone size and bone density, leading to dental problems. • UPF typically has a very high calorie density because it’s dry, and high in fat and sugar and low in fibre, so you get more calories per mouthful. • It displaces diverse whole foods from the diet, especially among low-income groups. And UPF itself is often micronutrient-deficient, which may also contribute to excess consumption. • The mismatch between the taste signals from the mouth and the nutrition content in some UPF alters metabolism and appetite in ways that we are only beginning to understand, but that seem to drive excess consumption. • UPF is addictive, meaning that for some people binges are unavoidable. • The emulsifiers, preservatives, modified starches and other additives damage the microbiome, which could allow inflammatory bacteria to flourish and cause the gut to leak. • The convenience, price and marketing of UPF urge us to eat constantly and without thought, which leads to more snacking, less chewing, faster eating, increased consumption and tooth decay. • The additives and physical processing mean that UPF affects our satiety system directly. Other additives may affect brain and endocrine function, and plastics from the packaging might affect fertility. • The production methods used to make UPF require expensive subsidy and drive environmental destruction, carbon emissions and plastic pollution, which harm us all.
Chris van Tulleken (Ultra-Processed People: The Science Behind Food That Isn't Food)
In conjunction with his colleagues, Frantisek Baluska from the Institute of Cellular and Molecular Botany at the University of Bonn is of the opinion that brain-like structures can be found at root tips. In addition to signaling pathways, there are also numerous systems and molecules similar to those found in animals. When a root feels its way forward in the ground, it is aware of stimuli. The researchers measured electrical signals that led to changes in behavior after they were processed in a "transition zone." If the root encounters toxic substances, impenetrable stones, or saturated soil, it analyzes the situation and transmits the necessary adjustments to the growing tip. The root tip changes direction as a result of this communication and steers the growing root around the critical areas. Right now, the majority of plant researchers are skeptical about whether such behavior points to a repository for intelligence, the faculty of memory, and emotions. Among other things, they get worked up about carrying over findings in similar situations with animals and, at the end of the day, about how this threatens to blur the boundary between plants and animals. And so what? What would be so awful about that? The distinction between plant and animal is, after all, arbitrary and depends on the way an organism feeds itself: the former photosynthesizes and the latter eats other living beings. Finally, the only other big difference is in the amount of time it takes to process information and translate it into action. Does that mean that beings that live life in the slow lane are automatically worth less than ones on the fast track? Sometimes I suspect we would pay more attention to trees and other vegetation if we could establish beyond a doubt just how similar they are in many ways to animals.

Then there is degree of contrast: When determining contrast, the pre-attentional parts analyze incoming sensory data against the background inputs. As an example, if you are at a party where many people are talking, not only is the sound gated but the semantic meanings in the hum of conversation are also gated. Essentially, both sound and the meanings-in-the-sounds are reduced in intensity so you don’t get overwhelmed by the incoming sensory inputs. However, should you hear your name from across the crowded room, Did you hear what happened between Michael and Jenny? the gating channel that is contrasting sound meanings in the room will open more widely and allow the sensory input through. It signals the cerebral cortex to pay attention. Once signaled, the cortex, in association with other parts of the brain, uses stochastic processes to enhance the signal so that what is being said can be heard in detail.

Chirality matters. In the curious case of the artificial fragrance limonene, the right-handed form smells like an orange, whereas the left-handed version of this simple ring-shaped molecule smells like a lemon. The smell receptors in your nose are sensitive to chirality, so right- and left-limonene transmit slightly different signals to your brain. Taste buds are less sensitive to the differences between right- and left-handed sugars. They both taste sweet, but our body’s fine-tuned digestive system can process only the right-handed forms. The artificial sweetener tagatose, a zero-calorie left-handed sugar substitute, exploits these properties. The tragic story of thalidomide also rests on handedness. The right-handed version of this drug alleviated morning sickness in pregnant women, but the left-handed variant that inevitably tagged along caused birth defects. Today the FDA imposes strict requirements for chirally pure drugs—regulations

Ive and Jobs have even obsessed over, and patented, the packaging for various Apple products. U.S. patent D558572, for example, granted on January 1, 2008, is for the iPod Nano box, with four drawings showing how the device is nestled in a cradle when the box is opened. Patent D596485, issued on July 21, 2009, is for the iPhone packaging, with its sturdy lid and little glossy plastic tray inside. Early on, Mike Markkula had taught Jobs to “impute”—to understand that people do judge a book by its cover—and therefore to make sure all the trappings and packaging of Apple signaled that there was a beautiful gem inside. Whether it’s an iPod Mini or a MacBook Pro, Apple customers know the feeling of opening up the well-crafted box and finding the product nestled in an inviting fashion. “Steve and I spend a lot of time on the packaging,” said Ive. “I love the process of unpacking something. You design a ritual of unpacking to make the product feel special. Packaging can be theater, it can create a story.

For example, when I observe something unusual in an experiment, it reverberates in my brain for a long while. Many circuits, especially the giant recurrent network of the hippocampus, can generate large numbers of neuronal trajectories without any signals from outside the brain. Even cultured brain tissue in a dish can induce a variety of spontaneous events. That is what neuronal circuits do.38 They do not just sit and wait to be stimulated. Based on these examples, now we may consider the possibility that learning is not an outside-in superimposition process where new neuronal sequences are built up with each novel experience. Instead, learning may be an inside-out matching process: when a spontaneously occurring neuronal trajectory, drawn from the available huge repertoire of trajectories, coincides with a useful action, that trajectory acquires meaning to the brain. The richer the experience, the higher the fraction of the meaningful trajectories, but there is always a large reservoir of available patterns.

the NetMind 'knocked' ... ageless and childish. Today she caught the tumble of roses it threw into her mind in its version of hello, and laughed ... its roses were followed by torrent of images Faith could barely process ... She showed the NetMind a hand, palm-out, their by-now familiar signal for 'slow-down' ... Worried, she sent it an image of a woman colored in darkness ... The image she'd sent was returned to her, but with the DarkMind scrubbed out ... An image of a thousand tears overlaid the snapshot of the PsyNet. The PsyNet was dying ... She sent the NetMind an image of arms outstretched, an offer of help. The response was of a globe, but a globe colored in the shades of the Net - white stars against a background of black velvet. Around that globe was a shimmering shield that repelled her hands. The Net wasn't ready for help. But there were cracks in the shield. She touched a finger to one crack, and knew that was Judd. The one next to it, Walker. And not far from them, Sascha. So many fine, fine cracks.
Nalini Singh (Branded by Fire (Psy-Changeling, #6))
Flow is an extremely potent response to external events and requires an extraordinary set of signals. The process includes dopamine, which does more than tune signal-to-noise ratios. Emotionally, we feel dopamine as engagement, excitement, creativity, and a desire to investigate and make meaning out of the world. Evolutionarily, it serves a similar function. Human beings are hardwired for exploration, hardwired to push the envelope: dopamine is largely responsible for that wiring. This neurochemical is released whenever we take a risk or encounter something novel. It rewards exploratory behavior. It also helps us survive that behavior. By increasing attention, information flow, and pattern recognition in the brain, and heart rate, blood pressure, and muscle firing timing in the body, dopamine serves as a formidable skill-booster as well. Norepinephrine provides another boost. In the body, it speeds up heart rate, muscle tension, and respiration, and triggers glucose release so we have more energy. In the brain, norepinephrine increases arousal, attention, neural efficiency, and emotional control. In flow, it keeps us locked on target, holding distractions at bay. And as a pleasure-inducer, if dopamine’s drug analog is cocaine, norepinephrine’s is speed, which means this enhancement comes with a hell of a high. Endorphins, our third flow conspirator, also come with a hell of a high. These natural “endogenous” (meaning naturally internal to the body) opiates relieve pain and produce pleasure much like “exogenous” (externally added to the body) opiates like heroin. Potent too. The most commonly produced endorphin is 100 times more powerful than medical morphine. The next neurotransmitter is anandamide, which takes its name from the Sanskrit word for “bliss”—and for good reason. Anandamide is an endogenous cannabinoid, and similarly feels like the psychoactive effect found in marijuana. Known to show up in exercise-induced flow states (and suspected in other kinds), this chemical elevates mood, relieves pain, dilates blood vessels and bronchial tubes (aiding respiration), and amplifies lateral thinking (our ability to link disparate ideas together). More critically, anandamide also inhibits our ability to feel fear, even, possibly, according to research done at Duke, facilitates the extinction of long-term fear memories. Lastly, at the tail end of a flow state, it also appears (more research needs to be done) that the brain releases serotonin, the neurochemical now associated with SSRIs like Prozac. “It’s a molecule involved in helping people cope with adversity,” Oxford University’s Philip Cowen told the New York Times, “to not lose it, to keep going and try to sort everything out.” In flow, serotonin is partly responsible for the afterglow effect, and thus the cause of some confusion. “A lot of people associate serotonin directly with flow,” says high performance psychologist Michael Gervais, “but that’s backward. By the time the serotonin has arrived the state has already happened. It’s a signal things are coming to an end, not just beginning.” These five chemicals are flow’s mighty cocktail. Alone, each packs a punch, together a wallop.

They also devised an ingeniously low-tech solution to a complex problem. Even highly verbal autistic adults occasionally struggle with processing and producing speech, particularly in the chaotic and generally overwhelming atmosphere of a conference. By providing attendees with name-tag holders and pieces of paper that were red on one side and yellow on the other, they enabled Autistics to communicate their needs and desires without having to articulate them in the pressure of the moment. The red side facing out signified, "Nobody should try to interact with me," while the yellow side meant, "Only people I already know should interact with me, not strangers." (Green badges were added later to signify, "I want to interact but am having trouble initiating, so please initiate an interaction with me.") These color-coded "interaction signal badges" turned out to be so useful that they have since been widely adopted at autistic-run events all over the world, and name-tag labels similar to Autreat ("autistic retreat") green badges have recently been employed at conferences for Perl programmers to indicate that the wearer is open to spontaneous social approaches.
Steve Silberman (NeuroTribes: The Legacy of Autism and the Future of Neurodiversity)
That is the wrong way to think about perception. Let’s simplify it. The problem is something like the following: The brain is locked inside a bony skull, and let’s assume for the sake of this argument that the perception problem is the problem of figuring out what’s out there in the world giving rise to sensory signals impinging on our sensory surfaces—eyes and ears, and so on. Now, these sensory signals are noisy and ambiguous. They won’t have a one-to-one mapping with things out there in the world, whatever those may be. They don’t come labeled for the brain with convenient tags like “this is vision” or “this is hearing.” So perception has to involve a process of inference, of “best guessing,” in which the brain combines the sensory data with prior expectations or (usually implicit) beliefs about the way the world is, to come up with its best guess about the causes of that sensory data. Within this framework, what we perceive is constituted by those multilevel predictions that try to account for the sensory signals. We perceive what the brain infers caused those signals, not the sensory signals themselves, nor things in the world “in themselves” either. There is no such thing as “direct perception” of the world or of the self.

As I became older, I was given many masks to wear. I could be a laborer laying railroad tracks across the continent, with long hair in a queue to be pulled by pranksters; a gardener trimming the shrubs while secretly planting a bomb; a saboteur before the day of infamy at Pearl Harbor, signaling the Imperial Fleet; a kamikaze pilot donning his headband somberly, screaming 'Banzai' on my way to my death; a peasant with a broad-brimmed straw hat in a rice paddy on the other side of the world, stooped over to toil in the water; an obedient servant in the parlor, a houseboy too dignified for my own good; a washerman in the basement laundry, removing stains using an ancient secret; a tyrant intent on imposing my despotism on the democratic world, opposed by the free and the brave; a party cadre alongside many others, all of us clad in coordinated Mao jackets; a sniper camouflaged in the trees of the jungle, training my gunsights on G.I. Joe; a child running with a body burning from napalm, captured in an unforgettable photo; an enemy shot in the head or slaughtered by the villageful; one of the grooms in a mass wedding of couples, having met my mate the day before through our cult leader; an orphan in the last airlift out of a collapsed capital, ready to be adopted into the good life; a black belt martial artist breaking cinderblocks with his head, in an advertisement for Ginsu brand knives with the slogan 'but wait--there's more' as the commercial segued to show another free gift; a chef serving up dog stew, a trick on the unsuspecting diner; a bad driver swerving into the next lane, exactly as could be expected; a horny exchange student here for a year, eager to date the blonde cheerleader; a tourist visiting, clicking away with his camera, posing my family in front of the monuments and statues; a ping pong champion, wearing white tube socks pulled up too high and batting the ball with a wicked spin; a violin prodigy impressing the audience at Carnegie Hall, before taking a polite bow; a teen computer scientist, ready to make millions on an initial public offering before the company stock crashes; a gangster in sunglasses and a tight suit, embroiled in a turf war with the Sicilian mob; an urban greengrocer selling lunch by the pound, rudely returning change over the counter to the black patrons; a businessman with a briefcase of cash bribing a congressman, a corrupting influence on the electoral process; a salaryman on my way to work, crammed into the commuter train and loyal to the company; a shady doctor, trained in a foreign tradition with anatomical diagrams of the human body mapping the flow of life energy through a multitude of colored points; a calculus graduate student with thick glasses and a bad haircut, serving as a teaching assistant with an incomprehensible accent, scribbling on the chalkboard; an automobile enthusiast who customizes an imported car with a supercharged engine and Japanese decals in the rear window, cruising the boulevard looking for a drag race; a illegal alien crowded into the cargo hold of a smuggler's ship, defying death only to crowd into a New York City tenement and work as a slave in a sweatshop. My mother and my girl cousins were Madame Butterfly from the mail order bride catalog, dying in their service to the masculinity of the West, and the dragon lady in a kimono, taking vengeance for her sisters. They became the television newscaster, look-alikes with their flawlessly permed hair. Through these indelible images, I grew up. But when I looked in the mirror, I could not believe my own reflection because it was not like what I saw around me. Over the years, the world opened up. It has become a dizzying kaleidoscope of cultural fragments, arranged and rearranged without plan or order.

We can all be "sad" or "blue" at times in our lives. We have all seen movies about the madman and his crime spree, with the underlying cause of mental illness. We sometimes even make jokes about people being crazy or nuts, even though we know that we shouldn't. We have all had some exposure to mental illness, but do we really understand it or know what it is? Many of our preconceptions are incorrect. A mental illness can be defined as a health condition that changes a person's thinking, feelings, or behavior (or all three) and that causes the person distress and difficulty in functioning. As with many diseases, mental illness is severe in some cases and mild in others. Individuals who have a mental illness don't necessarily look like they are sick, especially if their illness is mild. Other individuals may show more explicit symptoms such as confusion, agitation, or withdrawal. There are many different mental illnesses, including depression, schizophrenia, attention deficit hyperactivity disorder (ADHD), autism, and obsessive-compulsive disorder. Each illness alters a person's thoughts, feelings, and/or behaviors in distinct ways. But in all this struggles, Consummo Plus has proven to be the most effective herbal way of treating mental illness no matter the root cause. The treatment will be in three stages. First is activating detoxification, which includes flushing any insoluble toxins from the body. The medicine and the supplement then proceed to activate all cells in the body, it receives signals from the brain and goes to repair very damaged cells, tissues, or organs of the body wherever such is found. The second treatment comes in liquid form, tackles the psychological aspect including hallucination, paranoia, hearing voices, depression, fear, persecutory delusion, or religious delusion. The supplement also tackles the Behavioral, Mood, and Cognitive aspects including aggression or anger, thought disorder, self-harm, or lack of restraint, anxiety, apathy, fatigue, feeling detached, false belief of superiority or inferiority, and amnesia. The third treatment is called mental restorer, and this consists of the spiritual brain restorer, a system of healing which “assumes the presence of a supernatural power to restore the natural brain order. With this approach, you will get back your loving boyfriend and he will live a better and fulfilled life, like realize his full potential, work productively, make a meaningful contribution to his community, and handle all the stress that comes with life. It will give him a new lease of life, a new strength, and new vigor. The Healing & Recovery process is Gradual, Comprehensive, Holistic, and very Effective. www . curetoschizophrenia . blogspot . com E-mail: rodwenhill@gmail. com

Why Did the Stock Market Crash? The most persuasive explanation for the 1929 stock market crash blames the Federal Reserve. Throughout the 1920s, but particularly in 1927, the Fed pumped artificial credit into the loan market, pushing down interest rates from their free-market level. Lower interest rates exaggerated the feeling of prosperity, and misled businesses and investors. In a laissez-faire market where money and banking are not disturbed by the government, the interest rate is a price that tells borrowers how much capital citizens have saved and made available to fund projects. But when the Fed adopts an “easy-money” policy by pushing down interest rates, this signal is distorted and the interest rate no longer does its job of channeling the available capital into the most deserving projects. Instead, an unsustainable boom develops, with firms hiring workers and starting production processes that will have to be discontinued once the Fed slows down its injections of new money. Many economists point to the Fed hikes in interest rates during 1928 and 1929 as the cause of the stock market crash. In a sense this is true, but the deeper point is that the crash was made inevitable by the bubble in the stock market fueled by the artificially cheap credit preceding the hikes. In other words, when the Fed stopped pumping in gobs of new money that pushed up the stock market, investors came to their senses and asset prices plunged back towards their pre-bubble level.

Just how important a close moment-to-moment connection between mother and infant can be was illustrated by a cleverly designed study, known as the “double TV experiment,” in which infants and mothers interacted via a closed-circuit television system. In separate rooms, infant and mother observed each other and, on “live feed,” communicated by means of the universal infant-mother language: gestures, sounds, smiles, facial expressions. The infants were happy during this phase of the experiment. “When the infants were unknowingly replayed the ‘happy responses’ from the mother recorded from the prior minute,” writes the UCLA child psychiatrist Daniel J. Siegel, “they still became as profoundly distressed as infants do in the classic ‘flat face’ experiments in which mothers-in-person gave no facial emotional response to their infant’s bid for attunement.” Why were the infants distressed despite the sight of their mothers’ happy and friendly faces? Because happy and friendly are not enough. What they needed were signals that the mother is aligned with, responsive to and participating in their mental states from moment to moment. All that was lacking in the instant video replay, during which infants saw their mother’s face unresponsive to the messages they, the infants, were sending out. This sharing of emotional spaces is called attunement. Emotional stress on the mother interferes with infant brain development because it tends to interfere with the attunement contact. Attunement is necessary for the normal development of the brain pathways and neurochemical apparatus of attention and emotional selfregulation. It is a finely calibrated process requiring that the parent remain herself in a relatively nonstressed, non-anxious, nondepressed state of mind. Its clearest expression is the rapturous mutual gaze infant and mother direct at each other, locked in a private and special emotional realm, from which, at that moment, the rest of the world is as completely excluded as from the womb. Attunement does not mean mechanically imitating the infant. It cannot be simulated, even with the best of goodwill. As we all know, there are differences between a real smile and a staged smile. The muscles of smiling are exactly the same in each case, but the signals that set the smile muscles to work do not come from the same centers in the brain. As a consequence, those muscles respond differently to the signals, depending on their origin. This is why only very good actors can mimic a genuine, heartfelt smile. The attunement process is far too subtle to be maintained by a simple act of will on the part of the parent. Infants, particularly sensitive infants, intuit the difference between a parent’s real psychological states and her attempts to soothe and protect the infant by means of feigned emotional expressions. A loving parent who is feeling depressed or anxious may try to hide that fact from the infant, but the effort is futile. In fact, it is much easier to fool an adult with forced emotion than a baby. The emotional sensory radar of the infant has not yet been scrambled. It reads feelings clearly. They cannot be hidden from the infant behind a screen of words, or camouflaged by well-meant but forced gestures. It is unfortunate but true that we grow far more stupid than that by the time we reach adulthood.

Just as we perceive the outside world on the basis of sensory signals met with a top-down flow of perceptual expectations and predictions, the same applies to perceptions of the internal state of the body. The brain has to know what the internal state of the body is like. It doesn’t have direct access to it, even though both the brain and body happen to be wrapped within a single layer of skin. As with perception of the outside world, all the brain gets from the inside of the body are noisy, ambiguous electrical signals. Therefore it has to bring to bear predictions and expectations in order to make sense of the barrage of sensory signals coming from inside the body, in just the same way as for vision and all the other “classic” senses. And this is what’s collectively called interoception—perception of the body from within. The same computational principles apply. In this view, we can think of emotional conscious experiences, feeling states, in the framework of “interoceptive inference.” So emotions become predictions—“best guesses”—about the hidden causes of interoceptive signals, in the same way that experiences of the outside world are constituted by predictions of the causes of sensory signals. This gives a nice computational and mechanistic gloss to old theories of emotion that originated with William James and Karl Lange—that emotion has to do with perception of physiological change in the body and by the subsequent cognitive “appraisal” of these changes. The predictive-processing view adds to these theories by saying that emotional experience is the joint content of predictions about the causes of interoceptive signals at all levels of abstraction.

His great concern had to do with the fact that private fortunes were significantly outpacing investments in public services like schools, parks, and safety net programs. The process tends to begin gradually before accelerating under its own momentum. As people accumulate more money, they become less dependent on public goods and, in turn, less interested in supporting them. If they get their way, through tax breaks and other means, personal fortunes grow while public goods are allowed to deteriorate. As public housing, public education, and public transportation become poorer, they become increasingly, then almost exclusively, used only by the poor themselves.[6] People then begin to denigrate the public sector altogether, as if it were rotten at the root and not something the rich had found it in their interest to destroy. The rich and the poor soon unite in their animosity toward public goods—the rich because they are made to pay for things they don’t need and the poor because what they need has become shabby and broken. Things collectively shared, especially if they are shared across class and racial divides, come to be seen as lesser. In America, a clear marker of poverty is one’s reliance on public services, and a clear marker of affluence is one’s degree of distance from them. Enough money brings “financial independence,” which tellingly does not signal independence from work but from the public sector. There was a time when Americans wished to be free of bosses. Now we wish to be free of bus drivers. We wish for the freedom to withdraw from the wider community and sequester ourselves in a more exclusive one, pulling further and further away from the poor until the world they inhabit becomes utterly unrecognizable to us.[7]

Can fascism still exist? Clearly Stage One movements can still be found in all major democracies. More crucially, can they reach Stage Two again by becoming rooted and influential? We need not look for exact replicas, in which fascist veterans dust off their swastikas. Collectors of Nazi paraphernalia and hard-core neo-Nazi sects are capable of provoking destructive violence and polarization. As long as they remain excluded from the alliances with the establishment necessary to join the political mainstream or share power, however, they remain more a law and order problem than a political threat. Much more likely to exert an influence are extreme Right movements that have learned to moderate their language, abandon classical fascist symbolism, and appear “normal.” It is by understanding how past fascisms worked, and not by checking the color of shirts, or seeking echoes of the rhetoric of the national-syndicalist dissidents of the opening of the twentieth century, that we may be able to recognize it. The well-known warning signals—extreme nationalist propaganda and hate crimes—are important but insufficient. Knowing what we do about the fascist cycle, we can find more ominous warning signals in situations of political deadlock in the face of crisis, threatened conservatives looking for tougher allies, ready to give up due process and the rule of law, seeking mass support by nationalist and racialist demagoguery. Fascists are close to power when conservatives begin to borrow their techniques, appeal to their “mobilizing passions,” and try to co-opt the fascist following. Armed by historical knowledge, we may be able to distinguish today’s ugly but isolated imitations, with their shaved heads and swastika tattoos, from authentic functional equivalents in the form of a mature fascist conservative alliance. Forewarned, we may be able to detect the real thing when it comes along.

we were disposed, when starting out, to use them as the basis for our practice in this new context. In our early work with professors, however, we were not in a position to impose rules. We soon discovered the folly of making any pronouncements about the amount of writing, for instance, which might distinguish a writing-intensive approach, and took it as our goal to find professors willing to experiment and to take some steps toward engaging more with writing. We were consultants with expertise in how to use and teach writing, and we suggested strategies and provided materials. The fact that those strategies were grounded in research and theory, and could be signaled as criteria emerged in our process of discussion with faculty about the rationale for adopting particular teaching strategies. The emphasis was on alternative pedagogies, not on a list of rules requiring compliance. Just as one does not need to know that a particular word in a sentence is functioning as an adjective in order to use adjectives, faculty also neither needed, nor were necessarily concerned, to associate a practice like revision with criteria for an as yet non-existent W-course. What eventually became official criteria were initially the elements that we encouraged according to what an individual faculty member was able and willing to accommodate. The early pilot courses overall represented all the elements that we would identify as foundational to effective practice in teaching writing, but in very few courses were all of the criteria present. Faculty members positioned themselves across a spectrum of starting points in their views of writing and its role in their courses. For many professors in the Arts and social sciences, the “writing-intensive” label simply acknowledged that their courses included substantial amounts of writing. For many in the Physical Sciences, the concept as applied to their courses could, at first glance,

I see a direct connection between the Fuenta Magna Bowl and Ogma, I believe the former is an authentic yet misplaced artifact that has its origins in the Middle East as the Irish/Celtic mythology as well. Ogma -being the god/originator of speech and language- carries the syllable of 'Og' in his name (according to a renowned authority on Irish Mythology, James Swagger) which signals some process of initiation through which other members could join into this culture. His family connections were confused (according to, The Dictionary Of Mythology) but it is said that he was the brother of Dagda and Lugh; and Dagda owned a magical cauldron known as Undry, which was always full and used to satisfy his enormous appetite. The [Tales depict Dagda as a figure of immense power, armed with a magic club to kill nine men with one blow]. This symbolism shows another remarkable link, however, to ancient Egypt with the Nine Bows representing its enemies. With Richard Cassaro's work, we now know the significance of the Godself icon which we see on the Fuenta Magna Bowl; and yet my observation and surprise here lies in the fact that the Godself icon could simply refer to Dagda being a figure of immense power, but what is more astounding is when I found that the Latin word caldaria (whence 'cauldron' was taken) means a 'cooking pot'. This is indeed amazing, but that's not all! This Latin word has its etymological roots in the Semitic languages, where the Old Babylonian word 'kid' meaning 'to cut/soften/dissolve' got preserved into Arabic with the same meaning as well and even a new word got derived therefrom: 'kidr'; which literally means a 'cooking pot'. It also happens to refer to one of God's names (in Islam) with the meaning of: Almighty. Moreover, the word 'Undry' could be looked at as if it were composed of two syllables: Un and Dry, with 'Un' signaling a continuous action in present and 'Dry' meaning 'to generate' and 'pour out' in the Semitic language.

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

Just as there are batterers who will victimize partner after partner, so are there serial victims, women who will select more than one violent man. Given that violence is often the result of an inability to influence events in any other way, and that this is often the result of an inability or unwillingness to effectively communicate, it is interesting to consider the wide appeal of the so-called strong and silent type. The reason often cited by women for the attraction is that the silent man is mysterious, and it may be that physical strength, which in evolutionary terms brought security, now adds an element of danger. The combination means that one cannot be completely certain what this man is feeling or thinking (because he is silent), and there might be fairly high stakes (because he is strong and potentially dangerous). I asked a friend who has often followed her attraction to the strong and silent type how long she likes men to remain silent. “About two or three weeks,” she answered, “Just long enough to get me interested. I like to be intrigued, not tricked. The tough part is finding someone who is mysterious but not secretive, strong but not scary.” One of the most common errors in selecting a boyfriend or spouse is basing the prediction on potential. This is actually predicting what certain elements might add up to in some different context: He isn’t working now, but he could be really successful. He’s going to be a great artist—of course he can’t paint under present circumstances. He’s a little edgy and aggressive these days, but that’s just until he gets settled. Listen to the words: isn’t working; can’t paint; is aggressive. What a person is doing now is the context for successful predictions, and marrying a man on the basis of potential, or for that matter hiring an employee solely on the basis of potential, is a sure way to interfere with intuition. That’s because the focus on potential carries our imagination to how things might be or could be and away from how they are now. Spousal abuse is committed by people who are with remarkable frequency described by their victims as having been “the sweetest, the gentlest, the kindest, the most attentive,” etc. Indeed, many were all of these things during the selection process and often still are—between violent incidents. But even though these men are frequently kind and gentle in the beginning, there are always warning signs. Victims, however, may not always choose to detect them.

Was this luck, or was it more than that? Proving skill is difficult in venture investing because, as we have seen, it hinges on subjective judgment calls rather than objective or quantifiable metrics. If a distressed-debt hedge fund hires analysts and lawyers to scrutinize a bankrupt firm, it can learn precisely which bond is backed by which piece of collateral, and it can foresee how the bankruptcy judge is likely to rule; its profits are not lucky. Likewise, if an algorithmic hedge fund hires astrophysicists to look for patterns in markets, it may discover statistical signals that are reliably profitable. But when Perkins backed Tandem and Genentech, or when Valentine backed Atari, they could not muster the same certainty. They were investing in human founders with human combinations of brilliance and weakness. They were dealing with products and manufacturing processes that were untested and complex; they faced competitors whose behaviors could not be forecast; they were investing over long horizons. In consequence, quantifiable risks were multiplied by unquantifiable uncertainties; there were known unknowns and unknown unknowns; the bracing unpredictability of life could not be masked by neat financial models. Of course, in this environment, luck played its part. Kleiner Perkins lost money on six of the fourteen investments in its first fund. Its methods were not as fail-safe as Tandem’s computers. But Perkins and Valentine were not merely lucky. Just as Arthur Rock embraced methods and attitudes that put him ahead of ARD and the Small Business Investment Companies in the 1960s, so the leading figures of the 1970s had an edge over their competitors. Perkins and Valentine had been managers at leading Valley companies; they knew how to be hands-on; and their contributions to the success of their portfolio companies were obvious. It was Perkins who brought in the early consultants to eliminate the white-hot risks at Tandem, and Perkins who pressed Swanson to contract Genentech’s research out to existing laboratories. Similarly, it was Valentine who drove Atari to focus on Home Pong and to ally itself with Sears, and Valentine who arranged for Warner Communications to buy the company. Early risk elimination plus stage-by-stage financing worked wonders for all three companies. Skeptical observers have sometimes asked whether venture capitalists create innovation or whether they merely show up for it. In the case of Don Valentine and Tom Perkins, there was not much passive showing up. By force of character and intellect, they stamped their will on their portfolio companies.

To give you a sense of the sheer volume of unprocessed information that comes up the spinal cord into the thalamus, let’s consider just one aspect: vision, since many of our memories are encoded this way. There are roughly 130 million cells in the eye’s retina, called cones and rods; they process and record 100 million bits of information from the landscape at any time. This vast amount of data is then collected and sent down the optic nerve, which transports 9 million bits of information per second, and on to the thalamus. From there, the information reaches the occipital lobe, at the very back of the brain. This visual cortex, in turn, begins the arduous process of analyzing this mountain of data. The visual cortex consists of several patches at the back of the brain, each of which is designed for a specific task. They are labeled V1 to V8. Remarkably, the area called V1 is like a screen; it actually creates a pattern on the back of your brain very similar in shape and form to the original image. This image bears a striking resemblance to the original, except that the very center of your eye, the fovea, occupies a much larger area in V1 (since the fovea has the highest concentration of neurons). The image cast on V1 is therefore not a perfect replica of the landscape but is distorted, with the central region of the image taking up most of the space. Besides V1, other areas of the occipital lobe process different aspects of the image, including: •  Stereo vision. These neurons compare the images coming in from each eye. This is done in area V2. •  Distance. These neurons calculate the distance to an object, using shadows and other information from both eyes. This is done in area V3. •  Colors are processed in area V4. •  Motion. Different circuits can pick out different classes of motion, including straight-line, spiral, and expanding motion. This is done in area V5. More than thirty different neural circuits involved with vision have been identified, but there are probably many more. From the occipital lobe, the information is sent to the prefrontal cortex, where you finally “see” the image and form your short-term memory. The information is then sent to the hippocampus, which processes it and stores it for up to twenty-four hours. The memory is then chopped up and scattered among the various cortices. The point here is that vision, which we think happens effortlessly, requires billions of neurons firing in sequence, transmitting millions of bits of information per second. And remember that we have signals from five sense organs, plus emotions associated with each image. All this information is processed by the hippocampus to create a simple memory of an image. At present, no machine can match the sophistication of this process, so replicating it presents an enormous challenge for scientists who want to create an artificial hippocampus for the human brain.
