Much more commonly, they are linked to sensory deprivation, intoxication, illness, or injury. People with migraines may see shimmering arcs of light or tiny, Lilliputian figures of animals and people. People with failing eyesight, paradoxically, may become immersed in a hallucinatory visual world. Hallucinations can be brought on by a simple fever or even the act of waking or falling asleep, when people have visions ranging from luminous blobs of color to beautifully detailed faces or terrifying ogres. Those who are bereaved may receive comforting “visits” from the departed. In some conditions, hallucinations can lead to religious epiphanies or even the feeling of leaving one’s own body. Humans have always sought such life-changing visions, and for thousands of years have used hallucinogenic compounds to achieve them. As a young doctor in California in the 1960s, Oliver Sacks had both a personal and a professional interest in psychedelics. These, along with his early migraine experiences, launched a lifelong investigation into the varieties of hallucinatory experience. Here, with his usual elegance, curiosity, and compassion, Dr. Sacks weaves together stories of his patients and of his own mind-altering experiences to illuminate what hallucinations tell us about the organization and structure of our brains, how they have influenced every culture’s folklore and art, and why the potential for hallucination is present in us all, a vital part of the human condition.

    These individuals all lost some part of what we think of as our self, but they then offer remarkable, sometimes heart-wrenching insights into what remains. One man cut off his own leg. Another became one with the universe.We are learning about the self at a level of detail that Descartes (“I think therefore I am”) could never have imagined. Recent research into Alzheimer’s illuminates how memory creates your narrative self by using the same part of your brain for your past as for your future. But wait, those afflicted with Cotard’s syndrome think they are already dead; in a way, they believe that “I think therefore I am not.” Who—or what—can say that? Neuroscience has identified specific regions of the brain that, when they misfire, can cause the self to move back and forth between the body and a doppelgänger, or to leave the body entirely. So where in the brain, or mind, or body, is the self actually located? As Ananthaswamy elegantly reports, neuroscientists themselves now see that the elusive sense of self is both everywhere and nowhere in the human brain.

    We take for granted that we can remember, feel emotion, navigate, empathize, and understand the world around us, but how would our lives change if these abilities were dramatically enhanced--or disappeared overnight?Helen Thomson has spent years traveling the world, tracking down incredibly rare brain disorders. In Unthinkable she tells the stories of nine extraordinary people she encountered along the way. From the man who thinks he's a tiger to the doctor who feels the pain of others just by looking at them to a woman who hears music that’s not there, their experiences illustrate how the brain can shape our lives in unexpected and, in some cases, brilliant and alarming ways.Story by remarkable story, Unthinkable takes us on an unforgettable journey through the human brain. Discover how to forge memories that never disappear, how to grow an alien limb, and how to make better decisions. Learn how to hallucinate and how to make yourself happier in a split second. Find out how to avoid getting lost, how to see more of your reality, even how exactly you can confirm you are alive. Think the unthinkable.

     Early studies of the functions of the human brain used a simple method: wait for misfortune to strike-strokes, seizures, infectious diseases, lobotomies, horrendous accidents-and see how the victim coped. In many cases survival was miraculous, and observers could only marvel at the transformations that took place afterward, altering victims' personalities. An injury to one section can leave a person unable to recognize loved ones; some brain trauma can even make you a pathological gambler, pedophile, or liar. But a few scientists realized that these injuries were an opportunity for studying brain function at its extremes. With lucid explanations and incisive wit, Sam Kean explains the brain's secret passageways while recounting forgotten stories of common people whose struggles, resiliency, and deep humanity made modern neuroscience possible.

    While studying brain scans of several family members, he discovered that one perfectly matched a pattern he d found in the brains of serial killers. This meant one of two things: Either his family s scans had been mixed up with those of felons or someone in his family was a psychopath.Even more disturbing: The scan in question was his own.This is Fallon s account of coming to grips with this discovery and its implications. How could he, a happy family man who had never been prone to violence, be a psychopath? How much did his biology influence his behavior?Fallon shares his journey to answer these questions and the discoveries that ultimately led to his conclusion: Despite everything science can teach, humans are even more complex than we can imagine."

    Days earlier, she had been on the threshold of a new, adult life: at the beginning of her first serious relationship and a promising career at a major New York newspaper. Now she was labeled violent, psychotic, a flight risk. What happened?In a swift and breathtaking narrative, Cahalan tells the astonishing true story of her descent into madness, her family’s inspiring faith in her, and the lifesaving diagnosis that nearly didn’t happen.

    But it’s also messy, fallible, and about 50,000 years out of date. We cling to superstitions, remember faces but not names, miss things sitting right in front of us, and lie awake at night while our brains endlessly replay our greatest fears. Idiot Brain is for anyone who has ever wondered why their brain appears to be sabotaging their life—and what on earth it is really up to.A Library Journal Science Bestseller and a Finalist for the Goodreads Choice Award in Science Technology.

    These “psychosurgeons,” as they called themselves, occupied a gray zone between medical research and medical practice, and ended up subjecting untold numbers of people to the types of surgical experiments once limited to chimpanzees.The most important test subject to emerge from this largely untold chapter in American history was a twenty-seven-year-old factory worker named Henry Molaison. In 1953, Henry—who suffered from severe epilepsy—received a radical new version of the lobotomy, one that targeted the most mysterious structures in the brain. The operation failed to eliminate Henry’s seizures, but it did have an unintended effect: Henry left the operating room profoundly amnesic, unable to create new long-term memories. Over the next sixty years, Patient H.M., as Henry was known, became the most studied individual in the history of neuroscience, a human guinea pig who would teach us much of what we know about memory today.Luke Dittrich uses the case of Patient H.M. as a starting point for a kaleidoscopic journey, one that moves from the first recorded brain surgeries in ancient Egypt to the cutting-edge laboratories of MIT. He takes readers inside the old asylums and operating theaters where psychosurgeons conducted their human experiments, and behind the scenes of a bitter custody battle over the ownership of the most important brain in the world. Throughout, Dittrich delves into the enduring mysteries of the mind while exposing troubling stories of just how far we’ve gone in our pursuit of knowledge. It is also, at times, a deeply personal journey. Dittrich’s grandfather was the brilliant, morally complex surgeon who operated on Molaison—and thousands of other patients. The author’s investigation into the dark roots of modern memory science ultimately forces him to confront unsettling secrets in his own family history, and to reveal the tragedy that fueled his grandfather’s relentless experimentation—experimentation that would revolutionize our understanding of ourselves.Patient H.M. combines the best of biography, memoir, and science journalism to create a haunting, endlessly fascinating story, one that reveals the wondrous and devastating things that can happen when hubris, ambition, and human imperfection collide.

    If the conscious mind—the part you consider you—accounts for only a tiny fraction of the brain’s function, what is all the rest doing? This is the question that David Eagleman—renowned neuroscientist and acclaimed author of Sum—answers in a book as accessible and entertaining as it is deeply informed by startling, up-to-the-minute research.

    S. Ramachandran is at the forefront of his field-so much so that Richard Dawkins dubbed him the "Marco Polo of neuroscience." Now, in a major new work, Ramachandran sets his sights on the mystery of human uniqueness. Taking us to the frontiers of neurology, he reveals what baffling and extreme case studies can teach us about normal brain function and how it evolved. Synesthesia becomes a window into the brain mechanisms that make some of us more creative than others. And autism--for which Ramachandran opens a new direction for treatment--gives us a glimpse of the aspect of being human that we understand least: self-awareness. Ramachandran tackles the most exciting and controversial topics in neurology with a storyteller's eye for compelling case studies and a researcher's flair for new approaches to age-old questions. Tracing the strange links between neurology and behavior, this book unveils a wealth of clues into the deepest mysteries of the human brain.

    Charting the most cutting-edge scientific breakthroughs, and marshalling his decades of research and clinical practice, Walker explains how we can harness sleep to improve learning, mood and energy levels, regulate hormones, prevent cancer, Alzheimer's and diabetes, slow the effects of aging, and increase longevity. He also provides actionable steps towards getting a better night's sleep every night.

    Psychiatrist and psychoanalyst, Norman Doidge, M.D., traveled the country to meet both the brilliant scientists championing neuroplasticity and the people whose lives they’ve transformed - people whose mental limitations or brain damage were seen as unalterable. We see a woman born with half a brain that rewired itself to work as a whole, blind people who learn to see, learning disorders cured, IQs raised, aging brains rejuvenated, stroke patients learning to speak, children with cerebral palsy learning to move with more grace, depression and anxiety disorders successfully treated, and lifelong character traits changed. Using these marvelous stories to probe mysteries of the body, emotion, love, sex, culture, and education, Dr. Doidge has written an immensely moving, inspiring book that will permanently alter the way we look at our brains, human nature, and human potential.

    It promised to shed light on the deep mysteries of consciousness, as well as offer relief to addicts and the mentally ill. But in the 1960s, with the vicious backlash against the counter-culture, all further research was banned. In recent years, however, work has quietly begun again on the amazing potential of LSD, psilocybin and DMT. Could these drugs in fact improve the lives of many people? Diving deep into this extraordinary world and putting himself forward as a guinea-pig, Michael Pollan has written a remarkable history of psychedelics and a compelling portrait of the new generation of scientists fascinated by the implications of these drugs. How to Change Your Mind is a report from what could very well be the future of human consciousness.

    As the cancer progressed and was treated, the author experienced behavioral and cognitive symptoms connected to a range of mental disorders, including her professional specialty, schizophrenia. Lipska's family and associates were alarmed by the changes in her behavior, which she failed to acknowledge herself. Gradually, after a course of immunotherapy, Lipska returned to normal functioning, recalled her experience and, through her knowledge of neuroscience, identified the ways in which her brain changed during treatment. Lipska admits her condition was unusual; after recovery she was able to return to her research and resume her athletic training and compete in a triathalon. Most patients with similar brain cancers rarely survive to describe their ordeal. Lipska's memoir, coauthored with journalist McArdle, shows that strength and courage but also a encouraging support network are vital to recovery

    In some cases, this absence can be dangerous, but in others it can simply mean a different way of seeing the world.In The Science of Evil Simon Baron-Cohen, an award-winning British researcher who has investigated psychology and autism for decades, develops a new brain-based theory of human cruelty. A true psychologist, however, he examines social and environmental factors that can erode empathy, including neglect and abuse.Based largely on Baron-Cohen's own research, The Science of Evil will change the way we understand and treat human cruelty.
