Book Description
Used for gestures of communication, environmental exploration, and the grasping and manipulating of objects, the hand has a vital role in our lives. The hand's anatomical structure and neural control are among the most complex and detailed of human motor systems. Hand and Brain is a comprehensive overview of the hand's sensorimotor control. It discusses mediating variables in perception and prehension, the coordination of muscles with the central nervous system, the nature of movement control and hand positioning, hand-arm coordination in reaching and grasping, and the sensory function of the hand. In the last decade the rapid growth of neuroscience has been paralleled by a surge of interest in hand function. This reflects the fact that many of the fundamental issues facing neuroscientists today--including the problem of relating physiology to behavior--are central to the study of sensorimotor control of the hand. This book takes a broad interdisciplinary perspective on the control of hand movements that includes neurophysiology, neuroanatomy, psychology and neuropsychology, and biomechanics. The authors, who have all made significant scientific contributions in their own right, have sought to introduce their chosen topics in a manner that the undergraduate reader will be able to follow without sacrificing detailed and up-to-date coverage ofthe major developments. Uses an interdisciplinary approach including behavioral and neurophysiological data Describes a variety of experimental methodologies Treats neural computations necessary for the control of movement Covers implications of biomechanics for control, sensory mechanisms, and perceptual processing (haptics) Includes manipulative hand function as well as reaching Overviews each group of chapters using link sections Contains an integrated index and a glosssary The five sections cover: Mediating variables in perception and prehension The coordination of muscles with the central nervous system The nature of movement control and hand positioning Hand-arm coordination in reaching and grasping The sensory function of the hand

Book Description
This book presents the human hand from an overall perspective – from the first appearance of hand-like structures in the fins of big fishes living millions of years ago to today ́s and the future’s mind-controlled artificial hands. Much focus is given to the extremely well-developed sensation of the hand, its importance and its linkage to brain plasticity mechanisms. How can active hands rapidly expand their representational area in the brain? How can the sense of touch substitute for other deficient senses, such as in Braille reading where hand sensation substitutes for missing vision? How can the mere observation of active hands, belonging to others, activate the hand area in the observer’s own brain and what is the importance of this phenomenon for learning by imitation and the understanding of other peoples’ actions, gestures and body language? Why are some of us left-handed and what are the consequences from cultural and physiological viewpoints? Why does phantom sensation and phantom pain occur after hand amputation, and what can we do about it? Why can salamanders regenerate new extremities while humans can not? Is it possible to transplant a hand from a diseased individual to an amputee? Can artificial robotic hands be controlled by our mind, and can they ever gain the role of a normal hand? What role did the hand and the brain play during evolution in tool construction and development of language and cognitive functions? The hand has a high symbolic value in religion, literature and art and our hands have a key role in gestures and body language. The Hand and the Brain is aimed at anybody with interest in life sciences, in the medical field especially hand surgeons, orthopaedic specialists, neurologists and general practitioners, and those working in rehabilitation medicine and pain treatment. The original Swedish version of The Hand and the Brain has also become very popular among physiotherapists, occupational therapists, psychologists, and among a general population with an interest in science.

Book Description
"A startling argument . . . provocative . . . absorbing." --The Boston Globe "Ambitious . . . arresting . . . celebrates the importance of hands to our lives today as well as to the history of our species." --The New York Times Book Review The human hand is a miracle of biomechanics, one of the most remarkable adaptations in the history of evolution. The hands of a concert pianist can elicit glorious sound and stir emotion; those of a surgeon can perform the most delicate operations; those of a rock climber allow him to scale a vertical mountain wall. Neurologist Frank R. Wilson makes the striking claim that it is because of the unique structure of the hand and its evolution in cooperation with the brain that Homo sapiens became the most intelligent, preeminent animal on the earth. In this fascinating book, Wilson moves from a discussion of the hand's evolution--and how its intimate communication with the brain affects such areas as neurology, psychology, and linguistics--to provocative new ideas about human creativity and how best to nurture it. Like Oliver Sacks and Stephen Jay Gould, Wilson handles a daunting range of scientific knowledge with a surprising deftness and a profound curiosity about human possibility. Provocative, illuminating, and delightful to read, The Hand encourages us to think in new ways about one of our most taken-for-granted assets. "A mark of the book's excellence [is that] it makes the reader aware of the wonder in trivial, everyday acts, and reveals the complexity behind the simplest manipulation." --The Washington Post

Book Description
Does being left-handed make a person different in any way that matters? Since the late Stone Age, approximately 10 percent of humans have been left-handed, yet for most of human history left-handedness has been stigmatized. In On the Other Hand, Howard I. Kushner traces the impact of left-handedness on human cognition, behavior, culture, and health. A left-hander himself, Kushner has long been interested in the meanings associated with left-handedness, and ultimately with whether hand preference can even be defined in a significant way. As he explores the medical and cultural history of left-handedness, Kushner describes the associated taboos, rituals, and stigma from around the globe. The words “left” and “left hand” have negative connotations in all languages, and left-handers have even historically been viewed as disabled. In this comprehensive history of left-handedness, Kushner asks why left-handedness exists. He examines the relationship—if any—between handedness, linguistics, and learning disabilities, reveals how toleration of left-handedness serves as a barometer of wider cultural toleration and permissiveness, and wonders why the reported number of left-handers is significantly lower in Asia and Africa than in the West. Written in a lively style that mixes personal biography with scholarly research, On the Other Hand tells a comprehensive story about the science, traditions, and prejudices surrounding left-handedness.

Book Description
Brain asymmetry for speech is moderately related to handedness but what are the rules? Are symmetries for hand and brain associated with characteristics such as intelligence, motor skill, spatial reasoning or skill at sports? In this follow up to the influential Left, Right Hand and Brain (1985) Marian Annett draws on a working lifetime of research to help provide answers to crucial questions. Central to her argument is the Right Shift Theory - her original and innovative contribution to the field that seeks to explain the relationships between left-and right-handedness and left-and right-brain specialisation. The theory proposes that handedness in humans and our non-human primate relations depends on chance but that chance is weighted towards right-handedness in most people by an agent of right-hemisphere disadvantage. It argues for the existence of a single gene for right shift (RS+) that evolved in humans to aid the growth of speech in the left hemisphere of the brain. The Right Shift Theory has possible implications for a wide range of questions about human abilities and disabilities, including verbal and non verbal intelligence, educational progress and dyslexia, spatial reasoning, sporting skills and mental illness. It continues to be at the cutting edge of research, solving problems and generating new avenues of investigation - most recently the surprising idea that a mutant RS+ gene might be involved in the causes of schizophrenia and autism. Handedness and Brain Asymmetry will make fascinating reading for students and researchers in psychology and neurology, educationalists, and anyone with a keen interest in why people have different talents and weaknesses.

Book Description
From a pioneer in the field of mental health comes a groundbreaking book on the healing power of "mindsight," the potent skill that allows you to make positive changes in your brain–and in your life. Foreword by Daniel Goleman, author of Emotional Intelligence • Is there a memory that torments you, or an irrational fear you can't shake? • Do you sometimes become unreasonably angry or upset and find it hard to calm down? • Do you ever wonder why you can't stop behaving the way you do, no matter how hard you try? • Are you and your child (or parent, partner, or boss) locked in a seemingly inevitable pattern of conflict? What if you could escape traps like these and live a fuller, richer, happier life? This isn't mere speculation but the result of twenty-five years of careful hands-on clinical work by Daniel J. Siegel, M.D. A Harvard-trained physician, Dr. Siegel is one of the revolutionary global innovators in the integration of brain science into the practice of psychotherapy. Using case histories from his practice, he shows how, by following the proper steps, nearly everyone can learn how to focus their attention on the internal world of the mind in a way that will literally change the wiring and architecture of their brain. Through his synthesis of a broad range of scientific research with applications to everyday life, Dr. Siegel has developed novel approaches that have helped hundreds of patients. And now he has written the first book that will help all of us understand the potential we have to create our own lives. Showing us mindsight in action, Dr. Siegel describes • a sixteen-year-old boy with bipolar disorder who uses meditation and other techniques instead of drugs to calm the emotional storms that made him suicidal • a woman paralyzed by anxiety, who uses mindsight to discover, in an unconscious memory of a childhood accident, the source of her dread • a physician–the author himself–who pays attention to his intuition, which he experiences as a "vague, uneasy feeling in my belly, a gnawing restlessness in my heart and my gut," and tracks down a patient who could have gone deaf because of an inaccurately written prescription for an ear infection • a twelve-year-old girl with OCD who learns a meditation that is "like watching myself from outside myself" and, using a form of internal dialogue, is able to stop the compulsive behaviors that have been tormenting her These and many other extraordinary stories illustrate how mindsight can help us master our emotions, heal our relationships, and reach our fullest potential.

Book Description
The brain ... There is no other part of the human anatomy that is so intriguing. How does it develop and function and why does it sometimes, tragically, degenerate? The answers are complex. In Discovering the Brain, science writer Sandra Ackerman cuts through the complexity to bring this vital topic to the public. The 1990s were declared the "Decade of the Brain" by former President Bush, and the neuroscience community responded with a host of new investigations and conferences. Discovering the Brain is based on the Institute of Medicine conference, Decade of the Brain: Frontiers in Neuroscience and Brain Research. Discovering the Brain is a "field guide" to the brainâ€"an easy-to-read discussion of the brain's physical structure and where functions such as language and music appreciation lie. Ackerman examines: How electrical and chemical signals are conveyed in the brain. The mechanisms by which we see, hear, think, and pay attentionâ€"and how a "gut feeling" actually originates in the brain. Learning and memory retention, including parallels to computer memory and what they might tell us about our own mental capacity. Development of the brain throughout the life span, with a look at the aging brain. Ackerman provides an enlightening chapter on the connection between the brain's physical condition and various mental disorders and notes what progress can realistically be made toward the prevention and treatment of stroke and other ailments. Finally, she explores the potential for major advances during the "Decade of the Brain," with a look at medical imaging techniquesâ€"what various technologies can and cannot tell usâ€"and how the public and private sectors can contribute to continued advances in neuroscience. This highly readable volume will provide the public and policymakersâ€"and many scientists as wellâ€"with a helpful guide to understanding the many discoveries that are sure to be announced throughout the "Decade of the Brain."
