Book Description
Although cerebral dominance, the specialization of each side of the brain for different functions, was discovered in the 1860s, almost nothing was known for many years about its biological foundations, the study of which has undergone what can only be described as a revolution in the past decade and a half. Norman Geschwind and Albert Galaburda, two of the leaders of this new field, have assembled a distinguished group of investigators, each a pioneer in some aspect of the biology of dominance. The authors document human brain asymmetry at gross and microscopic levels in both adults and fetuses, its visualization in life by radiological methods, and its manifestation in brain waves. The evolutionary history of brain asymmetry over more than 300,000 years is shown in fossil skulls of humans and apes. In a dramatic reversal of older beliefs, asymmetry of anatomy, function, and chemistry has been demonstrated in many nonhuman species, and experiments have shown the role of hormones and other prenatal influences in the production of asymmetry. The surprising associations of non-right-handedness with twinning and immune disorders are discussed, as well as the asymmetrical malformation of the cortex in childhood dyslexia. This volume, combining scholarly authority and the excitement of the birth of a new discipline, will be welcomed by those to whom the implications of dominance are becoming evident--neuroscientists, neurologists, linguists, psychologists, experts in learning disorders, speech pathologists--and by specialists in nearly every branch of biology, medicine, and psychology.

Micro-, Meso- and Macro-Connectomics of the Brain
Author: Henry Kennedy
Publisher: Springer
ISBN: 3319277774
Category : Medical
Languages : en
Pages : 173
Book Description
This book has brought together leading investigators who work in the new arena of brain connectomics. This includes ‘macro-connectome’ efforts to comprehensively chart long-distance pathways and functional networks; ‘micro-connectome’ efforts to identify every neuron, axon, dendrite, synapse, and glial process within restricted brain regions; and ‘meso-connectome’ efforts to systematically map both local and long-distance connections using anatomical tracers. This book highlights cutting-edge methods that can accelerate progress in elucidating static ‘hard-wired’ circuits of the brain as well as dynamic interactions that are vital for brain function. The power of connectomic approaches in characterizing abnormal circuits in the many brain disorders that afflict humankind is considered. Experts in computational neuroscience and network theory provide perspectives needed for synthesizing across different scales in space and time. Altogether, this book provides an integrated view of the challenges and opportunities in deciphering brain circuits in health and disease.

The Neuropsychology of Language
Author: Robert Rieber
Publisher: Springer Science & Business Media
ISBN: 1468422928
Category : Psychology
Languages : en
Pages : 273
Book Description
The essays in this volume have been gathered together to honor Eric H. Lenneberg. Together they represent the broad range of topics in which he took some interest. For one of the distinguishing features of Eric Lenneberg's theoretical work was its synthesizing quality. He was interested in all of the scientific domains that might touch on the study of the mind and brain, and he carefully prepared himself in each of the pertinent disciplines. Beginning with his M. A. degree in linguistics from the University of Chicago in 1951, he went on to complete his doctoral studies in both linguistics and psychology at Harvard in 1955. This was followed by three years of postdoctoral specialization at Harvard Medical School in both neurology and chil dren's developmental disorders. This preparation and additional expe rience at the Children's Hospital Medical Center in Boston led directly to his now-classic monograph on the neuropsychology of language, The Biological Foundations of Language, which was published in 1967. It is interesting to note that while each of the essays grows out of empirical evidence, all without exception attempt to attain a level of theoretical explanation and generalization which is frequently missing from experimental work per se. Here again Lenneberg's work was no table for the vigor with which he sought out explanations and theories from neuropsychological data. In particular, hjs thesis that "language is the manifestation of species-specific cognitive propensities" was a hypothesis which he drew from necessarily indirect evidence.

Cerebral Localization

ISBN: 3642662048
Category : Medical
Languages : en
Pages : 340
Book Description
The demonstration of the basic brain mechanism through studying the partially commissure-sectioned case appears to be a most prom ising enterprise. The work with animals of HAMILTON and others in elucidating psychological brain process heretofore not imagined are mere indications of what the potential seems to be. Study of the partially disconnected patient seems equally revealing and productive in showing how many high level cognitive activities are managed in the cerebral flow of information. With respect to the issue of localization of function, it would seem clear that those cerebral areas clearly involved in the im mediate processing of raw sensory information can be selectively and specifically isolated and disconnected. In other words, the informational products of the long axonal type cells of Golgi, which MARCUS JACOBSON claims are the brain cells under strict genetic control, can be isolated, whereas the products of more complex and integrative mental activities which are managed by the more mutable Golgi type II cells do not seem to be so spec ifically disposed. Thus, these data suggest the lateralized spe cialities of the various left and right brain areas can make their contribution to the cerebral activities of the opposite hemisphere through almost any callosal area regardless of its size and loca tion. Indeed, this interpretation suggests to me that the long standing issue of the extent of localization could be better un derstood by considering the dichotomy in genetic specification as offered by HIRSCH and JACOBSON (1974).

How Whole Brain Thinking Can Save the Future
Author: James Olson
Publisher: Red Wheel/Weiser
ISBN: 1579830536
Category : Psychology
Languages : en
Pages : 344
Book Description
Our brains have numerous functioning parts, all of which serve us at any one moment. But decades of research reveal the existence of two basic brain “operating systems”—two fundamental ways in which the whole brain processes incoming information. Because of this phenomenon of brain dominance, most of us tend to favor the input of either our “dualistic” left-brain (which focuses on parts instead of wholes) or our holistic right hemisphere. This means that typically only half of our innate intelligence informs our thinking—and since the left-brain operating system dominates most males, our culture has itself become left-brain dominant. How Whole Brain Thinking Can Save the Future explores this left-brain bias in our civilization, revealing it to be the root cause for centuries of war, racism, and political polarization—and eons of misunderstanding between the sexes. While most of our technological and scientific progress is driven by left-brain thinking, the great advances to come will require that we consciously harness both sides of our brain to greatly improve our cognition. Award-winning author James Olson goes on to explain how we can achieve greater internal harmony between the two operating systems of the brain—both as individuals and as a culture—thus showing us how ad why thinking with our whole brains will lead us to peace and to the ultimate healing of our relationships and our world.

Publisher: National Academies Press
ISBN: 0309045290
Category : Medical
Languages : en
Pages : 195
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."

The Integrated Mind

Category : Medical
Languages : en
Pages : 190
Book Description
In this book we are trying to illuminate the persistent and nag ging questions of how mind, life, and the essence of being relate to brain mechanisms. We do that not because we have a commit ment to bear witness to the boring issue of reductionism but be cause we want to know more about what it's all about. How, in deed, does the brain work? How does it allow us to love, hate, see, cry, suffer, and ultimately understand Kepler's laws? We try to uncover clues to these staggering questions by con sidering the results of our studies on the bisected brain. Several years back, one of us wrote a book with that title, and the ap proach was to describe how brain and behavior are affected when one takes the brain apart. In the present book, we are ready to put it back together, and go beyond, for we feel that split-brain studies are now at the point of contributing to an understanding of the workings of the integrated mind. We are grateful to Dr. Donald Wilson of the Dartmouth Medi cal School for allowing us to test his patients. We would also like to thank our past and present colleagues, including Richard Naka mura, Gail Risse, Pamela Greenwood, Andy Francis, Andrea El berger, Nick Brecha, Lynn Bengston, and Sally Springer, who have been involved in various facets of the experimental studies on the bisected brain described in this book.

The Master and His Emissary

Category : Psychology
Languages : en
Pages : 615
Book Description
A new edition of the bestselling classic – published with a special introduction to mark its 10th anniversary This pioneering account sets out to understand the structure of the human brain – the place where mind meets matter. Until recently, the left hemisphere of our brain has been seen as the ‘rational’ side, the superior partner to the right. But is this distinction true? Drawing on a vast body of experimental research, Iain McGilchrist argues while our left brain makes for a wonderful servant, it is a very poor master. As he shows, it is the right side which is the more reliable and insightful. Without it, our world would be mechanistic – stripped of depth, colour and value.
