Nerve Center Quotes

I moaned then, tilting my head back to give him better access. His hands clamped on my waist, then moved—one going to cup my rear, the other sliding between us. This—this moment, when it was him and me and nothing between our bodies … His tongue scraped the roof of my mouth as he dragged a finger down the center of me, and I gasped, my back arching. “Feyre,” he said against my lips, my name like a prayer more devout than any Ianthe had offered up to the Cauldron on that dark solstice morning. His tongue swept my mouth again, in time to the finger that he slipped inside of me. My hips undulated, demanding more, craving the fullness of him, and his growl reverberated in my chest as he added another finger. I moved on him. Lightning lashed through my veins, and my focus narrowed to his fingers, his mouth, his body on mine. His palm pushed against the bundle of nerves at the apex of my thighs, and I groaned his name as I shattered

We’re here to take over the world-- that’s why we’re starting here in Hamilton, Indiana-- the nerve center of the entire planet.

Chakras are not the nerve centers of the body but subtler than that. Chakras are mostly behave like quantum quasi particles - they control the collective behavior of the body, mind and soul at various levels.

When her blue-black eyes lifted to his, everything disappeared. Their bodies dematerialized. The room they were in ceased to exist. Time became nothing. And in the void, in the wormhold, Wrath's chest opened up sure as if he'd been shot, a piercing pain licking over his nerve endings. He knew then that there are many ways for a heart to break. Sometimes it's from the crowding of life, the compression of responsibility and birthright and burden that just squeezed you until you couldn't breathe anymore. Even though your lungs were working just fine. And sometimes it's from the casual cruelty of a fate that took you far from where you had thought you would end up. And sometimes it's age in the face of youth. Or sickness in the face of health. But sometimes it's just because you're looking into the eyes of your lover, and your gratitude for having them in your life overflows...because you showed them what was on the inside and they didn't run scared or turn away: they accepted you and loved you and held you in the midst of your passion or your fear...or your combination of both. Wrath closed his eyes and focused on the soft pulls at his wrist. God, they were just like the beat of his heart. Which made sense. Because she was the center of his chest. And the center of his world.

How many times, I wondered, would I have to deal with the betrayal of this mass of nerves and blood vessels and muscle and skin?

Perception requires imagination because the data people encounter in their lives are never complete and always equivocal. For example, most people consider that the greatest evidence of an event one can obtain is to see it with their own eyes, and in a court of law little is held in more esteem than eyewitness testimony. Yet if you asked to display for a court a video of the same quality as the unprocessed data catptured on the retina of a human eye, the judge might wonder what you were tryig to put over. For one thing, the view will have a blind spot where the optic nerve attaches to the retina. Moreover, the only part of our field of vision with good resolution is a narrow area of about 1 degree of visual angle around the retina’s center, an area the width of our thumb as it looks when held at arm’s length. Outside that region, resolution drops off sharply. To compensate, we constantly move our eyes to bring the sharper region to bear on different portions of the scene we wish to observe. And so the pattern of raw data sent to the brain is a shaky, badly pixilated picture with a hole in it. Fortunately the brain processes the data, combining input from both eyes, filling in gaps on the assumption that the visual properties of neighboring locations are similar and interpolating. The result - at least until age, injury, disease, or an excess of mai tais takes its toll - is a happy human being suffering from the compelling illusion that his or her vision is sharp and clear. We also use our imagination and take shortcuts to fill gaps in patterns of nonvisual data. As with visual input, we draw conclusions and make judgments based on uncertain and incomplete information, and we conclude, when we are done analyzing the patterns, that out “picture” is clear and accurate. But is it?

we assert that in all mammals the center of primal, constructive consciousness and activity lies in the middle front of the abdomen, beneath the navel, in the great nerve center called the solar plexus. How do we know? We feel it, as we feel hunger or love or hate.

He began to explain to me that vegetation, and especially mature trees, are able to transmit harmony when one rests one’s nerve centers against a tree trunk. For hours he discoursed on the physical, energetic, and spiritual properties of plants.

I culled poetry from odors, sounds, faces, and ordinary events occurring around me. Breezes bulged me as if I were cloth; sounds nicked their marks on my nerves; objects made impressions on my sight as if in clay. There, in the soft language, life centered and ground itself in me and I was flowing with the grain of the universe. Language placed my life experiences in a new context, freeing me for the moment to become with air as air, with clouds as clouds, from which new associations arose to engage me in present life in a more purposeful way.

He is a monk. On his card it says INNER PEACE CENTER. I will go there in February for a tea ceremony. Does he actually know more than I do about inner peace? If he met my relatives, would he have a nervous breakdown? What about his relatives? Do they drive him nuts? The truth is everybody gets on everybody's nerves.

For all the talk of education, modern societies neglect to examine by far the most influential means by which their populations are educated. Whatever happens in our classrooms, the more potent and ongoing kind of education takes place on the airwaves and on our screens. Cocooned in classrooms for only our first eighteen years or so, we effectively spend the rest of our lives under the tutelage of news entities which wield infinitely greater influence over us than any academic institution can. Once our formal education has finished, the news is the teacher. It is the single most significant force setting the tone of public life and shaping our impressions of the community beyond our own walls. It is the prime creator of political and social reality. As revolutionaries well know, if you want to change the mentality of a country, you don't head to the art gallery, the department of education or the homes of famous novelists; you drive the tanks straight to the nerve center of the body politic, the news HQ.

Imagine a brain floating in a tank with millions and millions of electrodes attached to specific nerve centers. Now imagine these electrodes being selectively stimulated by a computer to cause the brain to believe that it was walking down Hollywood Boulevard chomping on a hamburger and checking out the chicks.

Now, if there was a technological foul-up, or if the tapes got jumbled, the brain would suddenly see Jesus Christ pass by down Hollywood Boulevard on his way to Golgotha, pursued by a crowd of angry people, being whipped along by seven Roman Centurions.

The brain would say, "Now hold on there!" And suddenly the entire image would go "pop" and disappear.

I've always had this funny feeling about reality. It just seems very feeble to me sometimes. It doesn't seem to have the substantiality that it's suppose to have.

The park was the heart of the city. He had come to the city – and with a knowing in his blood – he had established himself at the heart of it. Everyday he looked at the heart of it; every day; he was so stunned and awed and overwhelmed that just to think about it made him sweat. There was something, in the center of the park, that he had discovered. It was a mystery although it was in a glass case for everybody to see and there was a typewritten card over it telling all about it. But there was something the card couldn't say and what it couldn't say was inside him. He could not show the mystery to just anybody; but he had to show it to somebody. Who he had to show it to was a special person. This person could not be from the city but he didn't know why. He knew he would know him when he saw him and that he would have to see him soon or the nerve inside him would grow so big that he would be forced to steal a car or rob a bank or jump out of a dark alley onto a woman.

Seabiscuit took to stomping and bellowing for food day and night. His moans rang off the barn walls and worked on everyone's nerves, but no one gave in. "The whole ranch became centered on the job," Howard said. "Even the pigs quit grunting at him and the chickens kept out of his way.

For as Molly looked at him, she felt an immediate … she didn’t know what. Despite her love of the language arts, she also possessed an analytic mind, and that mind straightaway tried to seek out the why. And it couldn’t unearth the reason apart from his smile. Or, rather, how he smiled at her—warm and full-armed, like the embrace from a long-absent friend, without the slightest trace of fakeness or concealed motive. His was the most open face she’d ever seen in her life. Concomitant with these sensations, all delivered within a split second, was a thought, seemingly originating not in her mind but from the center of her torso and radiating out to the ends of each nerve, inexplicable in its suddenness and surety. A thought that children and very young people might have, but never middle-aged adults, especially one with a divorce behind her and the conviction that she already knew the world and what it was able to offer. But there it was, undeniably, the thought: I’m on a great adventure.

..., its unity, unfolding through all the panels, would have given the illusion of an endless whole, of water without a horizon or bank; nerves tense from work would be relaxed there...and to him who lived in the room it would have offered the refuge of a peaceable meditation in the center of a flowering aquarium.

So if you cannot concentrate one of the following is the cause: 1. "Deficiency of the motor centers." 2. "An impulsive and emotional mind." 3. "An untrained mind." The last fault can soon be removed by systematic practice. It is easiest to correct. The impulsive and emotional state of mind can best be corrected by restraining anger, passion and excitement, hatred, strong impulses, intense emotions, fretfulness, etc. It is impossible to concentrate when you are in any of these excited states. These can be naturally decreased by avoiding such food and drinks as have nerve weakening or stimulating influences, or a tendency to stir up the passions, the impulses and the emotions; it is a very good practice to watch and associate with those persons that are steady, calm, controlled and conservative.

The major impairments of ADD — the distractibility, the hyperactivity and the poor impulse control — reflect, each in its particular way, a lack of self-regulation. Self-regulation implies that someone can direct attention where she chooses, can control impulses and can be consciously mindful and in charge of what her body is doing. Like time literacy, self-regulation is also a distinct task of development in human life, achieved gradually from young childhood through adolescence and adulthood. We are born with no capacity whatsoever to self-regulate emotion or action. For self-regulation to be possible, specific brain centers have to develop and grow connections with other important nerve centers, and chemical pathways need to be established. Attention deficit disorder is a prime illustration of how the adult continues to struggle with the unsolved problems of childhood. She is held back precisely where the child did not develop, hampered in those areas where the infant or toddler got stuck during the course of development.

was just what she needed, and even after the show’s ridiculously self-centered participants began to grate on her nerves she couldn’t summon up the energy to find a more congenial activity. She was too tired to read, too tired to tackle the mountain of laundry on her closet floor, and too tired to head downstairs and see if Michelle and Sunita felt like going

I let the lights and the faces come at me. I let the nerves tap out signals to my brain center. I let go. The pink, green, and yellow neons flashed on and off with a definite rhythm, each with its own particular tempo. Together they screamed out a syncopated color rhapsody. The faces; the cafés; the speed of light, steel cars. Swift; quick. Red; green. Flash; off. Stop; go.

Among the studies conducted by the Center, four assessed smoked marijuana's ability to alleviate neuropathic pain, a notoriously difficult to treat type of nerve pain associated with cancer, diabetes, HIV/AIDS, spinal cord injury and many other debilitating conditions. Each of the trials found that cannabis consistently reduced patients' pain levels to a degree that was as good or better than currently available medications.

Something happens to you in an old-growth forest. At first you are curious to see the tremendous girth and height of the trees, and you sally forth, eager. You start to saunter, then amble, slower and slower, first like a fox and then an armadillo and then a tortoise, until you are trudging at the pace of an earthworm, and then even slower, the pace of a sassafras leaf's turning. The blood begins to languish in your veins, until you think it has turned to sap. You hanker to touch the trees and embrace them and lean your face against their bark, and you do. You smell them. You look up at leaves so high their shapes are beyond focus, into far branches with circumferences as thick as most trees. Every limb of your body becomes weighted, and you have to prop yourself up. There's this strange current of energy running skyward, like a thousand tiny bells tied to your capillaries, ringing with your heartbeat. You sit and lean against one trunk-it's like leaning against a house or a mountain. The trunk is your spine, the nerve centers reaching into other worlds, below ground and above. You stand and press your body into the ancestral and enduring, arms wide, and your fingers do not touch. You wonder how big the unseen gap. If you stay in one place too long, you know you'll root.

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

You heard me. Let someone else send you to your blaze of glory. You're a speck, man. You're nothing. You're not worth the bullet or the mark on my soul for taking you out." You trying to piss me off again, Patrick?" He removed Campbell Rawson from his shoulder and held him aloft. I tilted my wrist so the cylinder fell into my palm, shrugged. "You're a joke, Gerry. I'm just calling it like I see it." That so?" Absolutely." I met his hard eyes with my own. "And you'll be replaced, just like everything else, in maybe a week, tops. Some other dumb, sick shit will come along and kill some people and he'll be all over the papers, and all over Hard Copy and you'll be yesterday's news. Your fifteen minutes are up, Gerry. And they've passed without impact." They'll remember this," Gerry said. "Believe me." Gerry clamped back on the trigger. When he met my finger, he looked at me and then clamped down so hard that my finger broke. I depressed the trigger on the one-shot and nothing happened. Gerry shrieked louder, and the razor came out of my flesh, then swung back immediately, and I clenched my eyes shut and depressed the trigger frantically three times. And Gerry's hand exploded. And so did mine. The razor hit the ice by my knee as I dropped the one shot and fire roared up the electrical tape and gasoline on Gerry's arm and caught the wisps of Danielle's hair. Gerry threw his head back and opened his mouth wide and bellowed in ecstasy. I grabbed the razor, could barely feel it because the nerves in my hand seemed to have stopped working. I slashed into the electric tape at the end of the shotgun barrel, and Danielle dropped away toward the ice and rolled her head into the frozen sand. My broken finger came back out of the shotgun and Gerry swung the barrels toward my head. The twin shotgun bores arced through the darkness like eyes without mercy or soul, and I raised my head to meet them, and Gerry's wail filled my ears as the fire licked at his neck. Good-bye, I thought. Everyone. It's been nice. Oscar's first two shots entered the back of Gerry's head and exited through the center of his forehead and a third punched into his back. The shotgun jerked upward in Gerry's flaming arm and then the shots came from the front, several at once, and Gerry spun like a marionette and pitched toward the ground. The shotgun boomed twice and punched holes through the ice in front of him as he fell. He landed on his knees and, for a moment, I wasn't sure if he was dead or not. His rusty hair was afire and his head lolled to the left as one eye disappeared in flames but the other shimmered at me through waves of heat, and an amused derision shone in the pupil. Patrick, the eye said through the gathering smoke, you still know nothing. Oscar rose up on the other side of Gerry's corpse, Campbell Rawson clutched tight to his massive chest as it rose and fell with great heaving breaths. The sight of it-something so soft and gentle in the arms of something so thick and mountaineous-made me laugh. Oscar came out of the darkness toward me, stepped around Gerry's burning body, and I felt the waves of heat rise toward me as the circle of gasoline around Gerry caught fire. Burn, I thought. Burn. God help me, but burn. Just after Oscar stepped over the outer edge of the circle, it erupted in yellow flame, and I found myself laughing harder as he looked at it, not remotely impressed. I felt cool lips smack against my ear, and by the time I looked her way, Danielle was already past me, rushing to take her child from Oscar. His huge shadow loomed over me as he approached, and I looked up at him and he held the look for a long moment. How you doing, Patrick?" he said and smiled broadly. And, behind him, Gerry burned on the ice. And everything was so goddamned funny for some reason, even though I knew it wasn't. I knew it wasn't. I did. But I was still laughing when they put me in the ambulance.

But Keltner also found the compassionate instinct in the more instinctive and evolutionarily ancient parts of our nervous system: in the mammalian region known as the periaqueductal gray, which is located in the center of the brain, and causes mothers to nurture their young; and in an even older, deeper, and more fundamental part of the nervous system known as the vagus nerve, which connects the brain stem to the neck and torso, and is the largest and one of our most important bundles of nerves. It’s long been known that the vagus nerve is connected to digestion, sex, and breathing—to the mechanics of being alive. But in several replicated studies, Keltner discovered another of its purposes: When we witness suffering, our vagus nerve makes us care. If you see a photo of a man wincing in pain, or a child weeping for her dying grandmother, your vagus nerve will fire.

The Babel fish,” said The Hitchhiker’s Guide to the Galaxy quietly, “is small, yellow and leechlike, and probably the oddest thing in the Universe. It feeds on brainwave energy received not from its own carrier but from those around it. It absorbs all unconscious mental frequencies from this brainwave energy to nourish itself with. It then excretes into the mind of its carrier a telepathic matrix formed by combining the conscious thought frequencies with nerve signals picked up from the speech centers of the brain which has supplied them. The practical upshot of all this is that if you stick a Babel fish in your ear you can instantly understand anything said to you in any form of language. The speech patterns you actually hear decode the brainwave matrix which has been fed into your mind by your Babel fish. “Now it is such a bizarrely improbable coincidence that anything so mind-bogglingly useful could have evolved purely by chance that some thinkers have chosen to see it as a fina and clinching proof of the nonexistence of God. “The argument goes something like this: ‘I refuse to prove that I exist,’ says God, for proof denies faith, and without faith I am nothing.’ “‘But,’ says Man, ‘the Babel fish is a dead giveaway, isn’t it? It could not have evolved by chance. It proves you exist, and so therefore, by your own arguments, you don’t. QED.’ “‘Oh dear,’ says God, ‘I hadn’t thought of that,’ and promptly vanishes in a puff of logic.

The human brain is the most complex entity in the universe. It has between fifty and one hundred billion nerve cells, or neurons, each branched to form thousands of possible connections with other nerve cells. It has been estimated that laid end to end, the nerve cables of a single human brain would extend into a line several hundred thousand miles long. The total number of connections, or synapses, is in the trillions. The parallel and simultaneous activity of innumerable brain circuits, and networks of circuits, produces millions of firing patterns each and every second of our lives. The brain has well been described as “a supersystcm of systems.” Even though fully half of the roughly hundred thousand genes in the human organism are dedicated to the central nervous system, the genetic code simply cannot carry enough information to predetermine the infinite number of potential brain circuits. For this reason alone, biological heredity could not by itself account for the densely intertwined psychology and neurophysiology of attention deficit disorder. Experience in the world determines the fine wiring of the brain. As the neurologist and neuroscientist Antonio Damasio puts it, “Much of each brain’s circuitry, at any given moment in adult life, is individual and unique, truly reflective of that particular organism’s history and circumstances.” This is no less true of children and infants. Not even in the brains of genetically identical twins will the same patterns be found in the shape of nerve cells or the numbers and configuration of their synapses with other neurons. The microcircuitry of the brain is formatted by influences during the first few years of life, a period when the human brain undergoes astonishingly rapid growth. Five-sixths of the branching of nerve cells in the brain occurs after birth. At times in the first year of life, new synapses are being established at a rate of three billion a second. In large part, each infant’s individual experiences in the early years determine which brain structures will develop and how well, and which nerve centers will be connected with which other nerve centers, and establish the networks controlling behavior. The intricately programmed interactions between heredity and environment that make for the development of the human brain are determined by a “fantastic, almost surrealistically complex choreography,” in the apt phrase of Dr. J. S. Grotstein of the department of psychiatry at UCLA. Attention deficit disorder results from the miswiring of brain circuits, in susceptible infants, during this crucial period of growth.

The Brits call this sort of thing Functional Neurological Symptoms, or FNS, the psychiatrists call it conversion disorder, and almost everyone else just calls it hysteria. There are three generally acknowledged, albeit uncodified, strategies for dealing with it. The Irish strategy is the most emphatic, and is epitomized by Matt O’Keefe, with whom I rounded a few years back on a stint in Ireland. “What are you going to do?” I asked him about a young woman with pseudoseizures. “What am I going to do?” he said. “I’ll tell you what I’m goin’ to do. I’m going to get her, and her family, and her husband, and the children, and even the feckin’ dog in a room, and tell ’em that they’re wasting my feckin’ time. I want ’em all to hear it so that there is enough feckin’ shame and guilt there that it’ll keep her the feck away from me. It might not cure her, but so what? As long as I get rid of them.” This approach has its adherents even on these shores. It is an approach that Elliott aspires to, as he often tells me, but can never quite marshal the umbrage, the nerve, or a sufficiently convincing accent, to pull off. The English strategy is less caustic, and can best be summarized by a popular slogan of World War II vintage currently enjoying a revival: “Keep Calm and Carry On.” It is dry, not overly explanatory, not psychological, and does not blame the patient: “Yes, you have something,” it says. “This is what it is [insert technical term here], but we will not be expending our time or a psychiatrist’s time on it. You will have to deal with it.” Predictably, the American strategy holds no one accountable, involves a brain-centered euphemistic explanation coupled with some touchy-feely stuff, and ends with a recommendation for a therapeutic program that, very often, the patient will ignore. In its abdication of responsibility, motivated by the fear of a lawsuit, it closely mirrors the beginning of the end of a doomed relationship: “It’s not you, it’s … no wait, it’s not me, either. It just is what it is.” Not surprisingly, estimates of recurrence of symptoms range from a half to two-thirds of all cases, making this one of the most common conditions that a neurologist will face, again and again.

Swift came to the table and bowed politely. “My lady,” he said to Lillian, “what a pleasure it is to see you again. May I offer my renewed congratulations on your marriage to Lord Westcliff, and…” He hesitated, for although Lillian was obviously pregnant, it would be impolite to refer to her condition. “…you are looking quite well,” he finished. “I’m the size of a barn,” Lillian said flatly, puncturing his attempt at diplomacy. Swift’s mouth firmed as if he was fighting to suppress a grin. “Not at all,” he said mildly, and glanced at Annabelle and Evie. They all waited for Lillian to make the introductions. Lillian complied grudgingly. “This is Mr. Swift,” she muttered, waving her hand in his direction. “Mrs. Simon Hunt and Lady St. Vincent.” Swift bent deftly over Annabelle’s hand. He would have done the same for Evie except she was holding the baby. Isabelle’s grunts and whimpers were escalating and would soon become a full-out wail unless something was done about it. “That is my daughter Isabelle,” Annabelle said apologetically. “She’s teething.” That should get rid of him quickly, Daisy thought. Men were terrified of crying babies. “Ah.” Swift reached into his coat and rummaged through a rattling collection of articles. What on earth did he have in there? She watched as he pulled out his pen-knife, a bit of fishing line and a clean white handkerchief. “Mr. Swift, what are you doing?” Evie asked with a quizzical smile. “Improvising something.” He spooned some crushed ice into the center of the handkerchief, gathered the fabric tightly around it, and tied it off with fishing line. After replacing the knife in his pocket, he reached for the baby without one trace of self-consciusness. Wide-eyed, Evie surrendered the infant. The four women watched in astonishment as Swift took Isabelle against his shoulder with practiced ease. He gave the baby the ice-filled handkerchief, which she proceeded to gnaw madly even as she continued to cry. Seeming oblivious to the fascinated stares of everyone in the room, Swift wandered to the window and murmured softly to the baby. It appeared he was telling her a story of some kind. After a minute or two the child quieted. When Swift returned to the table Isabelle was half-drowsing and sighing, her mouth clamped firmly on the makeshift ice pouch. “Oh, Mr. Swift,” Annabelle said gratefully, taking the baby back in her arms, “how clever of you! Thank you.” “What were you saying to her?” Lillian demanded. He glanced at her and replied blandly, “I thought I would distract her long enough for the ice to numb her gums. So I gave her a detailed explanation of the Buttonwood agreement of 1792.” Daisy spoke to him for the first time. “What was that?” Swift glanced at her then, his face smooth and polite, and for a second Daisy half-believed that she had dreamed the events of that morning. But her skin and nerves still retained the sensation of him, the hard imprint of his body. “The Buttonwood agreement led to the formation of the New York Stock and Exchange Board,” Swift said. “I thought I was quite informative, but it seemed Miss Isabelle lost interest when I started on the fee-structuring compromise.” “I see,” Daisy said. “You bored the poor baby to sleep.” “You should hear my account of the imbalance of market forces leading to the crash of ’37,” Swift said. “I’ve been told it’s better than laudanum.

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.
