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.

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.

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
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).

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.

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.
