We'll explore these two subjects in the next chapter. Video for Phantoms In The Brain How To Building Your Brain for Success with Legendary Neuroscientist V.S. After going through the questions, I filled a syringe with ice−cold water and squirted it into her ear canal. Like most people, you probably take vision for granted. Larry's head smashed into the windshield, fracturing the frontal bones above his eyes and the orbital plates that protected his optic nerves. This argument sounds reasonable but in fact it is based on the fallacy that because you can imagine something to be logically possible, therefore it is actually possible. Episode one of a two-part BBC-4 special program hosted by neurologist V.S. I asked. And yet these are the very issues that fascinate us most of all. Dr. Monroe whistled softly. The ideas remained tucked away in my mind until a few years ago, when, as happens so often in science, someone made an accidental discovery, proving that I had missed the boat. Most of the day−to−day progress of science depends on simply adding another brick to the great edifice—a rather humdrum activity that the late historian Thomas Kuhn called "normal science." A Martian? This finding in itself is interesting but not altogether unexpected, given the known role of amygdala and temporal lobes in detecting gaze direction. As complex as the challenge seems, psychologists have found a rather simple way to measure emotional responses to faces, objects, scenes and events encountered in daily life. Thus one cell may respond to the dominant male in the monkey troop, another to the monkey's mate, another to the surrogate alpha male—that is, to the human experimenter. There's no direct evidence that all of this mainly involves your zombie—the how pathway—but the idea can be tested with brain imaging techniques. Modern physicians who are familiar with pseudocyesis assume it results from a pituitary or ovarian tumor that causes hormones to be released, mimicking the signs of pregnancy. In a similar vein, any creature that simply imagines having orgasms is unlikely to pass on its genes to the next generation. Their strange behavior implies the existence of a laughter circuit found mainly in portions of the limbic system and its targets in the frontal lobes. The mirror may work by providing visual feedback to unclench the hand, so that the clenching spasm is abolished. In the second experiment, Faraday moved a bar magnet to and fro in the center of a coil of wire, and, lo and behold, this action produced an electrical current in the wire. So with all this evidence staring them in the face, why do practitioners of Western medicine continue to ignore the many striking examples of direct links between mind and body? Since there is no possibility that Mr. Cooper could have sent a motor command to his left arm at the exact moment I questioned him, the result suggests that denial stems not merely from a sensory motor deficit. Now, slowly start moving your left eye horizontally toward the right, away from the person's head, until your blind spot falls directly on his head. " 'Sixty million and three years old? It is a source of great frustration to patient and physician alike and can emerge in many different guises. 85 Neglect is clinically important for two reasons. Why does it happen at all? Or, "Finally I have insight into the true nature of the cosmos." And even though the image sometimes blends quite well into the rest of the scene around it, like the monkey on your lap," he continued, "I realize that it is highly improbable and usually don't tell people about it." In our natural blind spot we have an especially obvious example of filling in—one that provides us with a valuable experimental opportunity to examine the "laws" that govern the process. Darwin realized that the bird might be using this as a sexual "come hither" in its courtship ritual, the striking metallic−looking disks on the feathers being the avian equivalent of jewelry. Or does it imply that the information doesn't exist anywhere in her brain? But labor has begun and we can proceed." As far as the motor cortex (which is not specialized for generating natural smiles) is concerned, this is as complex a feat as playing Rachmaninoff though it never had lessons, and therefore it fails utterly. I smiled to myself and said, "Hey, maybe we should try the device on Francis Crick." But just as the gravediggers began lowering his mother's roped casket into the earth, Willy began to laugh. We know, for instance, that intractable phantom pain may develop weeks or months after the limb is amputated. The other camp, represented by Stephen Jay Gould, calls members of the first camp "ultra−Darwinists" and argues that other factors must be kept in mind. Do the 'x's' on the left side of where you're looking (which I knew were in his scotoma) appear any different from the ones above and below?" Then I excuse myself to go to the restroom. An attractive, cheerful young lady, she was also extremely direct with a "don't pity me" attitude writ large on her face. But what if you used much simpler shapes than heads? I remember an especially striking example of this— a patient named Bill who came to see me six months after he had been diagnosed with a malignant brain tumor. 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. Though his knowledge of photoreceptors and and optics was impressive, his explanation—that there's a screen somewhere inside the brain where images are displayed—embodies a serious logical fallacy. We repeated the experiment several times with identical results. —Francis Crick On the morning of his mother's funeral in 1931, Willy Anderson—a twenty−five−year−old plumber from London—donned a new black suit, clean white shirt and nice shoes borrowed from his brother. (This has been tried with some success.) Yes," and "No. When Diane stepped into the shower one morning, she had no warning that the hot water heater was improperly vented. "I told him I was fine." If I ever locate an MPD patient with just two personalities, I intend to eliminate doubt by sending the person two bills. Furthermore, it's a two−way street: The body's effects on the mind are just as profound as those of the mind on the body, giving rise to complex feedback loops involved in generating and maintaining false pregnancy. A woman said that she once sat at her window watching cows in a neighboring meadow. (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.) Psychological defenses in normal people are especially puzzling because at first glance they seem detrimental to survival.3 Why would it enhance my survival to cling tenaciously to false beliefs about myself and the world? Maybe when the brain reaches a critical mass, new and unforeseen traits, properties that were not specifically chosen by natural selection, emerge. Second, each time the motor command center sends signals to the missing arm, information about the commands is also sent to the parietal lobe containing our body image. "Esmerelda, are you pointing?" All rights reserved. Indeed, I will take you at times to the very limits of scientific inquiry. They looked at their records and said, "You know, it's funny. PHANTOMS IN THE BRAIN Other books by Sandra Blakeslee Second Chances (with Judith Wallerstein, Ph.D.) … It 60 appears that vision is one of the areas in neuroscience where sooner or later we will have precise answers to big questions, but only time will tell. "Yes, they are equally strong." He simply couldn't live with the pain any longer. "You asked me if I could lift a table with my right hand and I said I could lift it about an inch." When I relate this example to medical students, the usual reaction is, Well, that was easy during Galileo's time, but surely now in the twentieth century all the major discoveries have already been made and we can't do any new research without expensive equipment and detailed quantitative methods. Their nipples become pigmented, as happens in pregnant women. She has thus created the illusion of observing two hands, when in fact she is only seeing the mirror reflection of her intact hand. "Yes. The problem of mind and matter, substance and spirit, illusion and reality, has been a major preoccupation of both Eastern and Western philosophy for millennia, but very little of lasting value has emerged. That really hurts!" Would he recognize the cube? But even though you assume that there is wallpaper behind your head, you don't literally see it. If there's such a thing as absence of free will, this is it. It's not moving." "Are they equally strong?" The dreaded disease leprosy is still quite common there and often leads to progressive mutilation and loss of limbs. Actually, Mrs. Dodd's confabulation is on the extreme end of the scale. By moving these patients out of the clinic and into the laboratory, we can conduct experiments that help reveal the deep architecture of our brains. Move my hand in a rhythmic manner so that my index finger repeatedly strokes and taps her nose in a random sequence like a Morse code. Notice the gross overrepresentation of mouth and hands. He smiled cheerfully. Aglioti also found to his surprise that one third of the women with radical mastectomies tested reported tingling, erotic sensations in their phantom nipples when their earlobes were stimulated. But these problems are also considered carefully by Ramachandran, who sees them not as groundless or crazy, but as emergency defense measures constructed by the unconscious to deal with sudden overwhelming bewilderments about one's body and the space around it. The amygdala—in the front pole of the temporal lobe—receives input from the sensory areas and sends messages to the rest of the limbic system to produce emotional arousal. If we gave Josh an actual line, asked him to look straight ahead and tell us whether he saw a complete line or piece missing, he might "cheat" inadvertently. "I daresay you haven't had much practice, " said the Queen. Redrawn from S. Zeki, A Vision of the Brain, 1993. Having received a command to move, the muscles execute the movement. To avoid being hounded by a free−floating anxiety, he adopted the convenient strategy of attributing it to something tangible—and the blister was the most convenient target. And this argument is valid whether you are talking about continents, heredity, warts or pseudocyesis. The eminent Philadelphia physician Silas Weir Mitchell2 first coined the phrase "phantom limb" after the Civil War. Diagnosing a patient's problem remains as much an art as a science, calling into play powers of observation, reason and all the human senses. Could you accelerate the pace of simian evolution through a combination of genetic engineering, hormonal intervention and artificial selection? I don't." Remarkably, the neural circuitry that generates these commands in Mirabelle's brain seems to have survived intact, despite the fact that she has received no visual or kinesthetic feedback from those "arms" at any point in her life. They stay frozen on the side, like this." 0:13. Even if certain circuits are hard−wired from birth, does it follow that they cannot be altered? You or I would naturally go for the shoelaces, but most paralyzed stroke patients—who do not suffer from denial—choose the light bulb, knowing their limitations. 86 When Ellen came to my lab, I first conducted a series of simple clinical tests to confirm the diagnosis of hemineglect. Phantoms In The Brain, using a series of case histories, introduces strange and unexplored mental worlds. When I would return to the topic of the brain tumor, he avoided talking about it, saying things like "Well, you know how these doctors sometimes incorrectly diagnose things." You know what? Will the phantom stretch out, like a cartoon character's rub− bery arm, or will it stop at a natural arm's length? "That's what the article said." Inquiries around (Cold water in the left ear or warm water in the right ear causes the eyes to drift repetitively to the left and jump to the right. Specifically, patients were told that they could earn five dollars if they threaded a light bulb into a bare socket on a heavy table lamp or ten dollars if they could tie a pair of shoelaces. And then, working backward, you consider plausible solutions to that challenge. Their decisions, once made, are irreversible: Once they signal to higher brain centers "Yes, this is a repetitive texture" or "yes, this is a straight line," what you perceive is irrevocable. They are, he feels, quite normal defense mechanisms (denial, repression, projection, confabulation, and so on) such as Freud delineated as uni− versai strategies of the unconscious when forced to accommodate the intolerable or unintelligible. Here are some examples: It's known that bees engage in very elaborate forms of communication including the so−called bee waggle dance. Very fortunate, for otherwise you wouldn't eat; you would just generate the qualia associated with satiety in your head. But here we have proof that something like repression is going on, albeit on a smaller time scale, with no possibility that the patient's behavior was unduly influenced by the experimenter. But ever since I've had a terrible pain in my phantom elbow, wrist and fingers." So her failure in the earlier task could not be explained by claiming that she was disoriented, clumsy or confused as a result of her stroke. I asked. But how can she get visual feedback when she doesn't have an arm? According to Wallace, as the human brain evolved, it encountered a new and equally powerful force called culture. The first person to explore this new world was Philip Martinez. Feel it. Go ahead and rub it if you don't believe me." In other words, natural selection could explain our talents for music, art, literature and other human intellectual achievements. A week later I telephoned him. "Can you read them out loud for me?" Likewise, even though you can imagine an unconscious zombie doing everything you can do, there may be some deep natural cause that prevents the existence of such a being! Except for a small headache, she was feeling better now and wished she could go home to clip her rose bushes and resume her daily morning walks along the beach near Point Loma, where she lived. Second, they illustrate our ignorance and illuminate the need for conducting experiments on topics that most people have ignored for no obvious reason; patients who manifest odd clinical phenomena are only one example. On the basis of this tenuous reasoning, surgeons have devised various treatments for phantom limb pain in which they cut and remove neuromas. The patients are a microcosm of you and me but "better," in that their defense mechanisms occur on a compressed time scale and are amplified tenfold. These historical examples and case studies gleaned from my notes support the view that specialized circuits or modules do exist, and we shall encounter several additional examples in this book. Ask your friend to tap and stroke the surface of the table with his right hand (as you watch) and then use his hand simultaneously to stroke and tap your left hand, which is hidden from view. In particular, we'll talk about three examples. Within a few seconds the patient's eyes started to move vigorously in a process called nystagmus. See for yourself." Some of them had been told that phantom sensations are imaginary and were relieved to learn that that isn't true. Is it any surprise that roughly one third of Americans claim to have seen angels? Although enigmatic disorders like these have intrigued and perplexed physicians throughout history, they are usually chalked up as curiosities— case studies stuffed into a drawer labeled "file and forget." In fact, they're moving now as I speak." The researchers were convinced that Drew was a reliable and honest reporter, and when test objects fell near the cusp of his good visual field, he always said so promptly. This is what you'd expect if input from the genital area were to invade the territory vacated by the foot. They knew perfectly well they were looking into a mirror and yet they made the same mistake as Ellen. (Of course, I would never say this in a National Institutes of Health [NIH] grant proposal, for most funding agencies still cling to the naive belief that science is all about hypothesis testing and then carefully dotting the "i's" and crossing the "t's." Both are languages in the strict technical sense, that is, they are information−rich messages that are intended to convey meaning, across synapses between different brain parts in one case and across the air between two people in the other. Our experiments with Arthur suggest that this distinction is not merely academic; it is embedded deep in the architecture of the brain. One is that God really does visit these people. Using one illusion to erase another doesn't seem very surprising after all. Mr. Cooper looked at me calmly and said, "I was gesticulating to make a point!" Does a partially comatose patient with akinetic mutism (seemingly awake and able to follow you with his eyes but unable to move or talk) have short−term memory? So it is with many of the currently debated issues concerning brain function. A fourth example that illustrates the complex interplay between genes and environment harks back to our observation that many amputees experience vivid phantom movements, both voluntary and involuntary, but in most the movements disappear eventually. "My thirty−year−old son thinks that I am not his father, that I am an impostor. Or would it use higher brain centers to reinterpret the sensations correctly as arising from the face alone? You might begin associating the sunflower image with relief from asthma. I stroked his lower jaw with the swab. One option is to tear up the entire script and start from scratch: completely revise your story to create a new model about the world and about yourself. Finally, I took a sheet of paper, put it in front of Ellen and asked her to draw a flower. Would he see the line as having a gap, or would he fill it in? They said, "Well, we had too many arms, so we just buried it in the garden, out behind the hospital." All kinds of sensations, images, and even memories were elicited by the electrode and the areas of the brain that were responsible could be mapped. This appears to be true whether you are talking about something as obvious as judging the brightness of print in a newspaper or something as subtle as detecting a blip in your internal emotional landscape. Would he suddenly stop having mystical experiences and become an atheist or an agnostic? I am finally experiencing this abstract thing called vision. Some of the "cases" I describe are really composites of several patients, including classics in the medical literature, as my purpose has been to illustrate salient aspects of the disorder, such as the neglect syndrome or temporal lobe epilepsy. Nadia, whose IQ measured between 60 and 70, was an artistic genius. But what to make of a gene for latent mathematical ability? This is admittedly a speculative argument even by the rather lax standards of evolutionary psychology. This phenomenon, as I mentioned earlier, is fairly common in elderly people with visual handicaps like macular degeneration, diabetic retinopathy, corneal damage and cataracts. We know that the hippocampus is required for acquiring and consolidating new memory traces. PDF Phantoms in the Brain: Probing the Mysteries of the Human Mind Read Online. Actual perceptions need to have vivid, subjective qualia because they are driving decisions and you cannot afford to hesitate. I have bad news." 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!" The third great scientific revolution, he claimed (modestly), was his own discovery of the unconscious and the corollary notion that the human sense of "being in charge" is illusory. "What is that?" As a result of this rather odd arrangement, if the left hemisphere is damaged, it loses its searchlight, but the right can compensate because it casts a searchlight on the entire world. For the most part the content of their imaginary world is mundane, perhaps involving an unfamiliar person, a bottle or a hat, but the hallucinations can also be quite funny. Irritation of these clumps and frayed nerve endings could be interpreted by the brain as pain in the missing limb. "It won't obey my mind. "It's frozen again. I turned it up to full strength even though you told me not to." An area immediately in front of it, called the supplementary motor area, appears to be in charge of more complex skills such as waving good−bye and grabbing a banister. Perhaps when asked to perform an action with her left hand, Mrs. Dodds sends motor commands to the paralyzed arm and copies of these commands are simultaneously sent to her body image centers (in the parietal lobes), where they are monitored and experienced as felt movements. Such whimsical pretend experiments are virtually impossible to carry out in real life. The neglect theory makes a very specific prediction—because he only neglects the left side of his body and not the right side, he should notice that the right arm isn't moving and say, "That's very odd, doctor; my arm isn't moving." For them, preadaptation, contingency and the like play only a minor role in evolution; they are "exceptions that prove the rule." "Can you point to me with your left?" mathematical equations, discovering several new theorems before the age of twenty−two. Physicians are generally reluctant to keep on prodding for fear of precipitating what the neurologist Kurt Goldstein called a "catastrophic reaction," which is simply medical jargon for "the patient starts sobbing" because her defenses crumble. Instead of using a line drawing to get this effect, Dr. Aglioti set two medium−sized dominoes on a table. Obviously Mrs. Dodds knew what had occurred and was aware of her surroundings. "Can you be a little more specific?" The mnemonic self: Your sense of personal identity—as a single person who endures through space and time—depends on a long string of highly personal recollections: your autobiography. At one end of the spectrum are modularists, who believe that different parts of the brain are highly specialized for mental capacities. Despite its apparent simplicity, smiling involves the careful orchestration of dozens of tiny muscles in the appropriate sequence. Satisfied, you approach me with your flow diagram and say, "Rama−chandran, this is what's going on in your brain!" "Don't do that!" Perhaps he was sensible enough to realize that the face in the mirror could not be anyone else's. The parenchyma is made out of a homogenous material with customizable composition to suit the need of various biomedical projects. But this finding did not convince his colleagues, so out of sheer desperation, Marshall swallowed a culture of the bacteria, did an endoscopy on himself a few weeks later and demonstrated that his gastrointestinal tract was studded with ulcers! (Some of the factors pertain to the actual selection process itself and others to the raw material that natural selection can act on. It was no use. Do I care about it? The study of phantom limbs offers fascinating glimpses of the architecture of the brain, its astonishing capacity for growth and renewal12 and may even explain why playing footsie is so enjoyable. One possibility is that it "arouses" the right hemisphere. I turned to Bill and asked, "Well, why do you think that's funny?" In other words, you don't merely deduce that the center of the doughnut is yellow; you literally see it as yellow.7 Now consider a related example. This second, adjacent structure sends commands to the eyes, instructing them to move. What do you make of it?" I hasten to add that as far as the patient is concerned, whatever changes have occurred are authentic—sometimes even desirable—and the physician has no right, really, to attribute a value label to such esoteric embellishments of personality. But I also see red. "What's gone?" The dampness of your hands is a sure giveaway of how you feel toward that person. Does illness result from chronic stress? My favorite example of this phenomenon involves the three little bones in our middle ear—the malleus, incus and stapes. phantoms in the brain probing the mysteries of the human mind Oct 08, 2020 Posted By Alexander Pushkin Media TEXT ID b61eb2e3 Online PDF Ebook Epub Library mysteries of the human mind book pdf free download link or read online here in pdf read online phantoms in the brain probing the mysteries of the human mind book pdf Darwin believed that his principle of natural selection could account not only for the emergence of morphological traits like fingers or noses, but also for the structure of the brain and therefore our mental capacities. "I can move my left arm—it's not paralyzed." For, if that were true, why would he be normal when listening to them on the telephone and delusional regarding his parents' identities only when he looked at them? Indeed, I discovered that most of my professional colleagues had not even heard of the experiment. This time the pen appeared just behind and above her right shoulder (but just outside her visual field). Short expirations followed each other in such rapid succession that Ruth's brain grew oxygen−starved and she broke into a sweat, at times holding her hand to her throat as if she were choking. Because I was born and raised in India, people often ask me whether I believe there are connections between the mind and body that Western cultures don't comprehend. The most parsimonious explanation for the whole spectrum of clinical signs you see in pseudocyesis would be that the intense longing for a child and associated depression might reduce levels of dopamine and norepinephrine—the "joy transmitters" in the brain. The second was the Darwinian revolution, which holds that we are puny, hairless neotenous apes that accidentally evolved certain characteristics that have made us successful, at least temporarily. "Can you use your right arm?" If this argument is correct, then perhaps it's not all that silly to ask whether you identify with your car. Would you connect the two lines with a diagonal line running through the blind spot? I lost my leg below the knee about two months ago but there's still something I don't understand. Every biologist I know has strong views on what these factors might be. What about Willy, who started giggling at his mother's funeral, and Ruth, who literally died laughing? And yet Dr. Aglioti's experiment and observations on patients like Diane suggest that there is in fact another being inside you that goes about his or her business without your knowledge or awareness. "Keep your eyes fixed on the same spot on my nose." There are many parallel neural connections between the temporal cortex and the amygdala. Even when the patients were given the same choice ten minutes later they unhesitatingly went for the bimanual task. It did not matter whether he used his left eye or right eye—if he looked straight ahead, he could not see anything on the left side of the world. (As many as 10 percent of autistic children have perfect pitch, compared with only 1 or 2 percent of the general population.) Was God talking to us directly through the GSR machine? Hence emotional changes alone cannot provide a complete explanation for religious preoccupation.4 The third explanation invokes connections between sensory centers (vision and hearing) and the amygdala, that part of the limbic system specialized in recognizing the emotional significance of events in the external world. You would be a neglect patient. But how can we be sure the student volunteer isn't just being metaphorical when she says "I feel my nose out there" or "The table feels like my own hand." In most respects, her eyesight was normal; she could name shapes of objects, recognize people and read books with no trouble. (I'll later explain why this doesn't happen with left parietal damage.) These anatomical facts have been known for a long time, but we still have no clear idea of how the brain works.6 Many older theories fall into two warring camps—modularity and holism—and the pendulum has swung back and forth between these two extreme points of view for the last three hundred years. Better yet, the pain disappeared. There's Einstein's general theory of relativity and Newton's universal law of gravitation in physics. During the last decade or so, I have gleaned many new insights into the workings of the human brain by studying such cases, and the urge to communicate these ideas is strong. Yet one would never argue from this that there is a cooking module in the brain specified by cooking genes that were honed by natural selection. Just punch it to see whether your GSR changes. What gives you that impression?" (All this was discovered mainly from animal experiments and neuroimaging studies in humans.)
