Second, even those patients who seem to recover from neglect quickly can be seriously handicapped because their indifference to the left during the first few days hinders rehabilitation. "It's all right," I said, "don't be alarmed. One especially enigmatic complaint frequently heard from patients is that every now and then the phantom hand becomes curled into a tight, white−knuckled fist, fingers digging into palm with all the fury of a prizefighter ready to deliver a knockout blow. Software. I know it's continuous. I asked. Her abdomen was vasdy enlarged and low, suggesting that the fetus had dropped. The real life "Dr. House" (he actually seems much nicer in his youtube videos!) . Indeed, after seeing these patients, I am convinced that the most effective antidote to the absurdity of the human condition may be humor rather than art. But why laughter? To be 147 sure, two months is better than nothing, but compared to the effects of an antibiotic like penicillin in improving the survival rates of pneumonia patients, this is hardly anything to boast about. Textbook writing is not my cup of tea, but I thought a popular book on the brain dealing mainly with my own experiences working with neurological patients might be fun to write. "What do you mean by cartoons? Mostly what I see is just people and animals and objects. The problem is that if you did this for every little piece of threatening information, your behavior would soon become chaotic and unstable; you would go mad. • Rationalization: We have seen many examples of this in this chapter. "3 Take a look at the shaded images in Figure 4.2. One of the most important principles in vision is that it tries to get away with as little processing as it can to get the job done. I am tempted to interview men participating in Lamaze classes and to measure prolactin levels in those who experience some of these couvadelike signs. Why not a hand fetish or a nose fetish? (You know you can't lift a truck; you know you can't give your boss a black eye, even if you'd like to.) She cleared her throat. 15:52. Why would merely "seeing" the cup be pulled away result in pain? Her memory for details was fine. Profound derangement to the mnemonic self can lead to multiple personality disorder or MPD. "Because there are more digits." After the surgery, people learn to use their pincers at the stump to grasp objects, turn them around and otherwise manipulate the material world. Given all the hints that there is something interesting going on, why not examine these claims in greater detail? In striking this balance between fact and fancy, I hope to stimulate your intellectual curiosity and to widen your horizons, rather than to provide you with hard and fast answers to the questions raised. Finally, on the floor of the thalamus is the hypothalamus, which seems to be concerned with regulating metabolic functions, hormone production, and various basic drives such as aggression, fear, and sexuality. Using similar pictures, we showed recently that neurons in the temporal lobes become altered permanently after the initial brief exposure—once you have "seen" the dog (Tovee, Rolls and Ramachandran, 1996). Not surprisingly, after the operations these patients often experience a vivid phantom limb, but to their dismay the phantom remains locked in the same position as before the amputation, as though a memory of the paralysis is carried over into the phantom limb. The parenchyma is made out of a homogenous material with customizable composition to suit the need of various biomedical projects. "10 Yet ultra−Darwinists steadfastly adhere to the view that almost all traits, other than those obviously learned, are specific products of natural selection. Sam was baffled. But is Joe really a complete stranger? One day I got a call from a young woman in Boston. Would you, the physician, really want to medicate such a patient and deny visitation rights to the Almighty? But this would not explain at least one recorded case involving a hypnotized person whose warts vanished on just one side of his body. It can serve multiple purposes (s) such as medical imaging research & treatment planning of non-invasive HIFU brain surgeries. So unlike you and me, who should display a heightened GSR response only for our moms, dads, spouses or lions, or even a loud thud or bang, the patient with temporal lobe epilepsy should show an increased galvanic skin response to everything under the sun. Those fortuitous combinations of genes that cause individuals to be slightly better adapted to a given local environment tend to multiply and propagate within a population since they increase the survival and reproduction of those individuals. This idea may even explain why feces infected with cholera, salmonellosis or shigella are especially foul smelling.4 Evolutionary psychology is one of those disciplines that tend to polarize scientists. The vigilant self: A vital clue to the neural circuitry underlying qualia and consciousness comes from two other neurological disorders—pen−duncular hallucinosis and "vigilant coma" or akinetic mutism. In a kind of tunnel vision, the patient's eyes stay focused on any small object that happens to be in her foveal vision (the high−acuity region of the eye), but she completely ignores all other objects in the vicinity. So the right visual cortex "sees" the left side of the world. You wake up in the morning, open your eyes and, voilà, it's all out there in front of you. condition is not enough in itself to generate qualia. For some weird reason, the amputation disturbs the equilibrium and resurrects the original body image, which has always been competing for attention.7 I mention these bizarre examples because they imply that phantom limbs emerge from a complex interplay of both genetic and experiential variables whose relative contributions can be disentangled only by systematic empirical investigations. Is there a window? This in turn could reduce the production of both follicle−stimulating hormone (FSH), which causes ovulation, and a substance called prolactin−inhibition factor.4 Low levels of these hormones would lead to a cessation of ovulation and menstruation and an elevation of the level of prolactin (the maternal hormone), which causes breast enlargement and lactation, nipple tingling and maternal behavior (although this has yet to be proved in humans), along with an increased production of estrogen and progesterone by the ovaries, contributing to the overall impression of pregnancy. To understand how this works, you need to know something about the autonomic nervous system—a part of your brain that controls the involuntary, seemingly automatic activities of organs, blood vessels, glands and many other tissues in your body. And like most of my colleagues I was very skeptical of his ideas. An important distinction must be made between perceptual and conceptual completion. This line of reasoning raises some fascinating possibilities. (I thought maybe he had lost the mirror box.) These few patients were clearly paying attention to objects they had previously ignored, raising a fascinating therapeutic possibility. Indeed, you can actually discover these laws and explore the limits of filling in by playing with your own blind spot. He just looks like him. I have apparently permanently altered a person's body image using a mirror. Nevertheless, they have no voluntary control over the apparitions, which usually appear without warning. Video for Phantoms In The Brain How To Building Your Brain for Success with Legendary Neuroscientist V.S. If she admitted them, how would she account for them? But in seeking brain centers concerned with religious experience and God, I realized that I had entered the "twilight zone" of neurology. The year was 1932 and money was tight. And odder still, the brain can not only discover how other brains work but also ask questions about its own existence: Who am I? • Reaction formation: This is the propensity to assert the exact opposite of what one suspects to be true of oneself. (A colleague suggested I title this book "The Man Who Mistook His Foot for a Penis.") In each of these cases, instead of the vague assertion that one is dealing with various degrees of consciousness—which is the standard answer—one should simply apply the three criteria specified. Everyday low prices and free delivery on eligible orders. The mirror may work by providing visual feedback to unclench the hand, so that the clenching spasm is abolished. The tail feathers of the argus pheasant have striking gray disk−shaped markings that look very much like those you see in Figure 4.3; they are, however, shaded left to right instead of up and down. It's that endless regress problem again.) Josh replied, "It looks like a continuous column of 'x's.' Something odd was afoot. Dr. Ramachandran has countless other interests too: in the nature of religious experience and the remarkable "mystical" syndromes associated with dysfunction in the temporal lobes, in the neurology of laughter and tickling, and—a vast realm—in the neurology of suggestion and placebos. Although the most common delusion among Capgras' patients is the assertion that a parent is an impostor, even more bizarre examples can be found in the older medical literature. Philip had heard about my experiments with phantom limbs in local press reports. He can do this even in his sleep, sometimes mumbling the exact time while dreaming. The answer may be that these patients experience a general blunting of all their emotional responses and therefore do not have a baseline for comparison. Cooper!" The grandeur of the human potential is visible only when we take all the possibilities into account, resisting the temptation to fall into polarized camps or to ask whether a given function is localized or not localized.7 As we shall see, it's much more useful to tackle each problem as it comes along and not get hung up taking sides. Perhaps as the brain adjusts and cells slowly make new connections, there is a slight error in the remapping so that some of the sensory input from touch receptors is accidentally connected to the pain areas of the brain. Instead of placing his left hand into the other side of the box, in an exact mirror image of the phantom, he inserted his right hand, palm up. She never knew when to slow down, changing the angle of the coffeepot, because she couldn't estimate how fast the liquid was rising in the cup. Better yet, the pain disappeared. The first of these, he said, was the Copernican revolution, in which a geocentric or earth−centered view of the universe was replaced with the idea that earth is just a speck of dust in the cosmos. As a second example, imagine a species of Amazonian electric fish that is very intelligent, in fact, as intelligent and sophisticated as you or I. Many neurologists have explored this in their patients, and the usual answer is that they don't deny other problems—like my patient Grace who, when I offered her candy if she could tie shoelaces, shot back at me, "You know I'm diabetic, doctor. Can you change the design to eliminate my fingers?" I know this sounds astonishing so I will demonstrate to you the malleability of your own body image and how you can alter it profoundly in just a few seconds. But if he got up casually, wiped the remains of the fruit from his face and continued walking, you would probably burst out laughing, thereby letting others standing nearby know that they need not rush to his aid. To enable patients like Irene to perceive real movement in their nonexistent arms, we constructed a virtual reality box. Some parts of this circuit handle emotions—the feeling of merriment that accompanies laughter—whereas other parts are involved in the physical act itself, but at present we do not know which parts are doing what. But saying that tumor regression arises from variability is not saying a hell of a lot; it's hardly an explanation. (It used to be called sociobiology, a term that fell into disrepute for political reasons.) Why or how the immune system could selectively eliminate warts on one side over another is a mystery that invites further flights of speculation. What is meant by a symbolic description in the brain? Once, after Thurber's glasses shattered, he said, "I saw a Cuban flag flying over a national bank, I saw a gay old lady with a gray parasol walk right through the side of a truck, I saw a cat roll across a street in a small striped barrel. (Called the galvanic skin response or GSR, this simple little procedure forms the basis of the famous lie detector test. It is no different in kind from problems that arise from any translation, and thus there is no need to invoke a great division in nature between the world of qualia and the material world. I then gave her the injection, with the same syringe containing saline solution, waited a bit and asked, "Can you move your right arm?" "No." He smiled cheerfully. It forces my brain to swivel my eyeballs toward something important out there in the visual scene, pay selective attention to it and say, "Aha!" To achieve all this, I need to have in my brain not only a representation of the world and various objects in it but also a representation of myself, including my own body within that representation—and it is this peculiar recursive aspect of the self that makes it so puzzling. This phenomenon is not surprising, given the important role that gaze direction5 plays in primate social communications—the averted gaze of guilt, shame or embarrassment; the intense, direct gaze of a lover or the threatening stare of an enemy. What do you make of it?" The limbic system is concerned with emotional behavior and evaluation of the emotional significance and potential value of events in the external world. It is one of the most original and accessible neurology books of our generation. After a diligent search I found one that was and one that wasn't.) When I gave him the mirror to try that same afternoon, he was able to open his phantom hand instantly. My lipstick is crooked and my hair unkempt." What does the theory state? Shut your right eye and look at the small white dot near the middle of the illustration with your left eye. But could his failure to produce a strong galvanic skin response to his parents be part of a more global disturbance in his emotional abilities? Talking to them is an uncanny experience. "Don't do that," he repeated. It's not yet clear exactly how this "interplay" occurs or what its function might be. 0:30 [Read] Phantoms in the Brain: Probing the Mysteries of the Human Mind Review. Then, many psychiatrists argue, along comes a blow to the head (or some other unrecognized release mechanism) and the repressed sexuality toward a mother or father comes flaming to the surface. Charles Darwin pointed out that when the bird goes through its courtship ritual, the tail points up. 15 This explanation is not as far−fetched as it seems, since it's been well known for some time that the right hemisphere tends to be more emotionally volatile than the left. The observation that some cancers occasionally regress spontaneously doesn't necessarily prove that hypnosis or a positive attitude can induce such remissions. She gave me a puzzled look.14 The "model" of denial that we considered earlier provides a partial explanation for both the subtle forms of denial that we all engage in, as well as the vehement protests of denial patients. If you showed him the Pepsi, put it in a box, switched off the room lights for thirty seconds and then switched them on again, would he reach for the Pepsi (or utterly fail like the zombie in Denise)? "Keep your eyes fixed on the same spot on my nose." "Yes, I can use my left arm." What if you challenged your visual system by deliberately misaligning the two half lines—shifting the top line segment to the left and the bottom line segment to the right? Maybe he had no emotions, period. "Dr. Ramachandran," he said, "I'm hoping you can help me." The visual system might then apply surface interpolation to "fill in" the color and texture of the table, saying in effect, "Well, there's this grainy stuff here; it must be the same grainy stuff all over." "Yes. "The pen is inside the mirror and I can't reach it!" The answer is clear. He says the same thing about his mother, that we are not his real parents." I was not sure. But if someone asked Denise first to look at the slot and then turned off the lights before asking her to post the letter, she could no longer do so. I was careful not to tell him what we hoped to find, so as not to bias his responses. It's possible, for instance, that the two functions are laid down in close proximity and were dependent on each other during the learning phase, but in the adult each function can survive without the other. "Mrs. Macken, how long have you been paralyzed?" Hardy, received his scribbles and immediately thought Ramanujan was a crackpot. As an analogy, suppose you are watching the program Baywatch on television. One possibility is that the universal human tendency to seek authority figures—giving rise to an organized priesthood, the participation in rituals, chanting and dancing, sacrificial rites and adherence to a moral code—encourages conformist behavior and contributes to the stability of one's own social group—or "kin"—who share the same genes. Responding correctly to a mirror image requires you simultaneously to hold in your mind the reflection as well as the object that is producing it and then perform the required mental gymnastics to locate correctly the object that produced the reflection. He looked puzzled. And likewise for the brain sciences. To cope with the world's uncertainties, you need a way of gauging the salience of events before you relay a message to the rest of the limbic system and to the hypothalamus telling them to assist you in fighting or fleeing. Most of us can imagine the scenes these people describe—a miniature police van with miniature criminals running about—but we exert conscious control over such imaginations. And even more puzzling, how do you explain the observation that some patients with pseudocyesis do not have an elevated prolactin level or that in many patients labor pains begin at exactly nine months? There's even a report of a woman who saw her recently deceased husband three times a week. Later in the sequence, Arthur made another duplication—one model was old, one young and a third even younger. "Look," I said. But how can she get visual feedback when she doesn't have an arm? Again, the sheer statistical improbability of the two sequences of taps and strokes—one seen on the table surface and one felt on your hand—lead the brain to conclude that the table is now part of your body. Is the alien left hand controlled by an unconscious zombie, or is it controlled by parts of her brain that have qualia and consciousness? —John Archibald Wheeler This book has been incubating in my head for many years, but I never quite got around to writing it. The penis resembles the foot, he argues, hence the fetish. Such co−opting of mechanisms is the rule rather than the exception in the evolution of mental and physical traits (al− though in this case, the co−opting occurs for a related, higher−level function rather than for a completely different function). Is there a particular style of information processing that produces qualia, or are there some types of neurons exclusively associated with qualia? The region corresponding to the missing object is simply covered with the same color of paint or wallpaper. The emergence of these ghostly sensations in his missing limb led the sea lord to proclaim that his phantom was "direct evidence for the existence of the soul." It's hard to find my own shoes! Would repeated irrigation permanently "cure" Mrs. Macken of denial and make her willing to 111 participate in rehabilitation? Dr. Monroe whistled softly. Apparently their son did not treat either of them as impostors when they spoke to him over the telephone. At some point you need to say "this is it" and plant a flag on it, and it's the planting of the flag that we call qualia. "Doctor, every time I have sexual intercourse, I experience sensations in my phantom foot. The fellow is astonished, but the waiter seems completely undisturbed. (A striking example is the zombie in Chapter 4.) According to Wallace, this means that the aborigine or Cro−Magnon possesses a potential intelligence that vastly exceeds anything that he might need for coping with his natural environment. Second, the looking glass syndrome may not be a direct consequence of neglect, even though it is usually accompanied by neglect. Just think of the numerous occasions when you actually clenched your fist and felt your nails biting in your palm. Or, when he has a seizure, does he lack the censoring or editing that occurs in normal memory so that he is forced to record every trivial detail—resulting in a paradoxical improvement in his memory? For instance, almost every culture that we know of has some form of cooking, however primitive. To these seemingly intractable problems, Ramachandran brings a fresh and different approach, which stems from his inquiries as to what phantoms are, and how and where they are generated in the nervous system. But my experiments with these patients have taught me that this is not how the brain works. Far from being curiosities, these syndromes illustrate fundamental principles of how the normal human mind and brain work, shedding light on the nature of body image, language, laughter, dreams, depression and other hallmarks of human nature. Trying to hide my surprise, I pointed to a mahogany table at the end of the hall and asked her whether she could lift that with her right hand. He paused, apparently to let this sink in. That is, the smile takes the particular form that it does not because of natural selection alone but because it evolved from the very opposite—the threat grimace! Dr. Persinger's observation was not a complete surprise as I've always suspected that the temporal lobes, especially the left lobe, are somehow involved in religious experience. He consulted a surgeon colleague and scheduled the operation, but to the surgeon's astonishment, he said he had a special request: "After you amputate my leg, could you please pickle it in a jar of formaldehyde and give it to me?" Before we meet the patients, crack mysteries and speculate about brain organization, I'd like to take you on a short guided tour of the human brain. And there is apparently no limit to what you can choose. If you pinch my toe, it is "I" who experiences the pain, not "it." But if you skip the translation and use a cable, so that the nerve impulses themselves go directly to the color area, then perhaps you'll say, "Oh, my God, I see exactly what you mean. Ether was given routinely during labor and she'd expected it. When Mendeleyev arranged elements sequentially according to their atomic weights to create the periodic table, he found that some elements didn't quite "fit"—their atomic weights seemed wrong. "I've come back! Again, if mathematical ability is simply a function of general intelligence, a result of the brain's getting bigger and better overall, then more intelligent people should be better at math, and vice versa. "I think he accepts me intellectually, doctor, but not emotionally," he said. Can the brain be tricked into unlearning a phantom? da Vinci's horse, (a) and (c) reprinted from Nadia, by Loraa Selfe, with permission from Academic Press (New York). I was personally drawn into medicine, a discipline full of ambiguities, because its Sherlock Holmes style of inquiry greatly appealed to me. Stroking the skin surface on this second map also evoked precisely localized sensations on the individual fingers: Touch here and he says, "Oh, that's my thumb," and so on. But if you asked me whether I literally see the missing piece of finger, I would say no—for all I know, someone could have actually sliced two pieces of finger and put them on either side of the finger in front to fool me. • Studying patients with phantom limbs has given me insights into the inner working of the brain that go far beyond the simple questions I started with four years ago when Tom first walked into my office. Next I bashed the table surface with a hammer as the student watched. It will be a time of great euphoria and celebration for novice researchers entering the field. But the study of cosmology gives us a sense of timelessness, of being part of something much larger. When I give talks to lay audiences around the country, one question comes up again and again: "When are you brain scientists ever going to come up with a unified theory for how the mind works? The real brain, it turns out, is far messier than what's implied by these simple−minded dichotomies. If that were the case, Arthur would recognize his parents but would not experience any emotions when looking at their faces. Soon after the article appeared, I received hundreds of letters from readers who tried the various experiments I had described or had devised new ones of their own. Ramachandran?" Furthermore, there are dozens of ways to solve an environmental problem, and unless you know the evolutionary history, taxonomy and paleontology of the animal you are looking at, you cannot figure out the exact route taken by a particular trait (like feathers, laughter or hearing) as it evolved into its present form. Or they will go all the way into the thalamus, a brain relay station that processes signals before they are sent to the cortex, and again find that they have not helped the patient. And more generally, how does the activity of tiny wisps of protoplasm in the brain lead to conscious experience? Two eminent English neurologists, Lord Russell Brain and Henry Head (yes, these are their real names), coined the phrase "body image" for this vibrant, internally constructed ensemble of experiences— the internal image and memory of one's body in space and time. We are bedeviled by paradox: On the one hand our lives seem so important—with all those cherished highly personal memories—and yet we know that in the cosmic scheme of things, our brief existence amounts to nothing at all. It was almost as though someone had used a wet towel to erase all the makeup on the left side of his mother's face! I couldn't believe my ears. Here is a woman whose brain creates Walt Disney cartoons in defiance of copyright. Since he regularly saw these bacteria in ulcers, he started wondering whether perhaps they actually caused ulcers. 126 These changes give rise to what some neurologists have called "temporal lobe personality." Am I afraid of it? For example, Venus's−flytrap snaps shut only if its trigger hairs inside the trap are stimulated twice in succession, apparently retaining a memory of the first stimulus and comparing it with the second to "infer" that something has moved. Or, given the well−known clinical observation that the left frontal lobe seems to be involved in feeling "good," maybe you'd want to stimulate a region over your left eye to see whether you could induce a natural high. She now lives in a country home, where she keeps a large herb garden, entertains friends and carries on an active, though protected, life. "Are you clapping?" What did you say each time?" What did the monkey actually "feel" when its face was being stroked? Of course not. Though Philip's response was exciting and provided some support for my hypothesis about learned paralysis, I went home that night and asked myself, "So what? Instead of a natural expression, you produce a hideous grimace. During the last four weeks, had he ever noticed any of these peculiar referred sensations in his phantom hand when his face had been touched—when he shaved every morning, for example? Indeed, there are many other principles of this sort (including plain old Lady Luck or contingency) that are not covered by the phrase "natural selection.
