Annotation This edited book brings together research reports on the asymmetry of brain function in various species, including humans, dogs, birds, lizards and bees. As shown in a wide range of species, and, as we now know, not solely in humans, the left and right sides of the brain process information in different ways and control different responses or patterns of behaviour. Since this discovery, many new methods have become available to reveal the processes involved in the development, function and evolution of this important attribute of the brain. Chapters consider the evidence for asymmetry of sensory receptors, left-right differences in information processing and asymmetrical control of behaviour. The latter includes lateralization of bird song and use of the magnetic compass in navigation. Other chapters report studies on handedness, hemispheric asymmetries in emotional processing and perception of symmetry in humans. The importance of the degree, or strength, of asymmetry is discussed and the conclusion is that asymmetry of the brain enhances its efficiency. Other chapters provide evidence that early experience influences the development of asymmetry. All of the contributors have strong backgrounds in research and they discuss up-to-date discoveries on lateralized brain and behaviour.
Is "right-brain" thought essentially creative, and "left-brain" strictly logical? Joseph B. Hellige argues that this view is far too simplistic. Surveying extensive data in the field of cognitive science, he disentangles scientific facts from popular assumptions about the brain's two hemispheres. In Hemispheric Asymmetry, Hellige explains that the "right brain" and "left brain" are actually components of a much larger cognitive system encompassing cortical and subcortical structures, all of which interact to produce unity of thought and action. He further explores questions of whether hemispheric asymmetry is unique to humans, and how it might have evolved. This book is a valuable overview of hemispheric asymmetry and its evolutionary precedents.
The twenty-three contributions in Brain Asymmetry provide a comprehensive survey of modern research on laterality and brain asymmetry, showcasing new approaches and novel domains in which knowledge of the asymmetrical functioning of the brain is a key issue for the complete understanding of the phenomenon. Of particular note is the inclusion of material on laterality, learning, attention, and emotion and their relation to subcortical and peripheral structures and processes. In addition, the clinical relevance of brain asymmetry for neuropsychological and psychopathological practice is surveyed.Following a preface and historical overview, chapters are divided into eight parts that cover: Phylogenetic Antecedents and Anatomical Bases; Perceptual, Cognitive, and Motor Lateralization; Attention and Learning; Central-Autonomic Integration; Emotional Lateralization; Interhemispheric Interaction; Ontogeny and Developmental Disabilities; and Psychopathology.Contributors : Marie T.

State-of-the-art research on brain asymmetry, explained from molecular to clinical levels. Hemispheric asymmetry is one of the basic aspects of perception and cognitive processing. The different functions of the left and right hemispheres of the brain have been studied with renewed interest in recent years, as scholars explore applications to new areas, new measuring techniques, and new theoretical approaches. This volume provides a comprehensive view of the latest research in brain asymmetry, offering not only recent empirical and clinical findings but also a coherent theoretical approach to the subject. In chapters that report on the field at levels from the molecular to the clinical, leading researchers address such topics as the evolution and genetics of brain asymmetry; animal models; findings from structural and functional neuroimaging techniques and research; sex differences and hormonal effects; sleep asymmetry; cognitive asymmetry in visual and auditory perception; and auditory laterality and speech perception, memory, and asymmetry in the context of developmental, neurological, and psychiatric disorders.

The Lateralized Brain: The Neuroscience and Evolution of Hemispheric Asymmetries is an up-to-date teaching resource for neuroscience faculty members that teach courses concerning hemispheric asymmetries. The book provides students with all relevant information on the subject, while also giving aspiring researchers in the field an up-to-date overview of relevant, previous work. It is ideal for courses on hemispheric asymmetries, that is, the functional or structural differences between the left and the right hemispheres of the brain, and also highlights how the widespread use of modern neuroimaging techniques, such as fMRI and DTI has completely changed the way hemispheric asymmetries are currently investigated. According to the preface, the main aim of The Lateralized Brain is to provide "an up-to-date teaching resource on hemispheric asymmetries ... [and] to introduce undergraduate students of all levels to the fascinating topics of hemispheric asymmetries" (p. xv)... (Sebastian Ocklenburg and Onur Güntürkün) have succeeded admirably in their stated aim and are to be congratulated on undertaking the mammoth task they set themselves. They can be proud of what they have accomplished.~ Alan A. Beaton, Department of Psychology, Swansea University, Swansea, UK, in Laterality: Asymmetries of Body, Brain and Cognition, July, 2018. Includes references to key articles, books, protocols and online resources for additional, detailed study Presents classic studies that helped define the field Covers key concepts and methods that are explained in separate call out boxes for quick overview Provides introductory short stories (e.g. classic clinical cases) as a starting point for each chapter
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.
Cerebral Lateralization is Norman Geschwind's last and perhaps most controversial work. Cowritten with Albert M. Galaburda, it presents his bold theory of left-handedness and brain development, exploring as no other current study has done the biology behind cerebral dominance or the specialization of the left and right sides of the brain for different functions.This book, which illustrates and expands material that appeared in three issues of The Archives of Neurology, provides extensive discussions of the anatomical and chemical differences between the hemispheres, their development in fetal life, their evolution, and their relationship to hemispheric function. The various factors that affect brain structure - endocrinological, immunological, and genetic - particularly dominance characteristics in intrauterine life, are fully covered, offering new insights into the nature-nurture question and pointing up the importance of the fetal environment in altering the properties of the brain.Many other intriguing areas are explored - the evidence for anatomical asymmetry during evolution and in other species, the concept of handedness and problems of its assessment, anatomical alterations in the brains of dyslexics, the advantages and disadvantages of cerebral dominance such as the elevated rate of left-handedness in certain highly skilled occupations, its association with childhood learning disorders, immune disease, and twinning. Seyeral sections are devoted to diseases with unilateral predominance in the brain or the body and those associated with particular dominance patterns.The final chapter, which deals with asymmetries in physics and chemistry and their possible relationship to the eventual development of dominance in both humans and other species, shows the importance of asymmetry of the nervous system in probably all animals.Norman Geschwind, M.D. (1926-1984) was James Jackson Putnam Professor of Neurology, Harvard Medical School, Director of the Neurological Unit, Beth Israel Hospital, and Professor of Psychology at MIT. Albert M. Galaburda, M.D. is Associate Professor of Neurology at Harvard Medical School. A Bradford Book.
Discusses brain asymmetry from four perspectives - function, evolution, development and causation - covering a wide range of species, including humans.
Clinical neuroscience refers to a subfield of neuroscience which focuses on the scientific study of fundamental mechanisms that underly disorders and diseases of the central nervous system and brain. It aims to develop new methods of conceptualizing and diagnosing such disorders and developing new therapies. The human nervous system is divided into two symmetric halves, but a closer examination of the brain reveals functional and anatomical lateralization. Brain asymmetry is detected in terms of behavior, structure and function. Experiential, evolutionary, genetic, developmental and pathological factors are hypothesized to have a role in this lateralization. Defects in brain asymmetry are linked to a variety of neurological disorders, and certain disorders exacerbate the brain asymmetries. Various disorders related with brain asymmetries include schizophrenia and dyslexia. This book explores all the important aspects of brain aging in the present day scenario. Those with an interest in this field would find it helpful.
