Download or read book Hemispheric Communication written by Frederick L. Kitterle and published by Routledge. This book was released on 2020-02-10 with total page 389 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this book is to provide a comprehensive overview of the way in which the two hemispheres of the brain interact. Some chapters address the nature of this interaction, the anatomical substrates that may account for greater or lesser hemispheric interaction, and the role of sex and handedness in hemispheric interaction. Others address the use of different experimental methods and clinical populations to understand the nature of hemispheric interaction. In addition to current research, this book also provides an important historical overview of the early research questions about hemispheric function and interaction that have helped to shape current views of and approaches to the study of brain function. Special coverage includes: * a comprehensive history of early research on cerebral laterality and hemispheric communication, including work by Pavlov; * a critical analysis of techniques and methologies to study hemispheric communication; * research on anatomical substrates which may underly functional differences between hemispheres and hemispheric communication; * implications of handedness for hemispheric communication; * research on individual differences in hemispheric function; * comprehensive research on sex and handedness from physiological, anatomical, and functional perspectives; and * attentional differences in hemispheric function.
Download or read book Micro Meso and Macro Connectomics of the Brain written by Henry Kennedy and published by Springer. This book was released on 2016-03-10 with total page 173 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Interhemispheric Communication During Face Processing written by Lyndsay Baird and published by . This book was released on 2009 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: It is widely acknowledged that the cerebral hemispheres do not operate in isolation during the processing of complex visual stimuli. Patterns of interhemispheric communication are believed to be integral to cognitive abilities yet despite this, both the circumstances under which communication takes and the nature of the information that can be communicated remain relatively poorly understood. The experiments in this thesis address the nature of interhemispheric communication during the processing of face and identity information using a range of divided visual field paradigms. The first line of enquiry explored the nature of identity information that can be communicated interhemispherically. Specifically, the aim was to establish whether abstract identity driven collaboration could be achieved with stimuli denoting the same concept or if cross-hemispheric communication is restricted to more low-level, stimulus driven interactions. Further studies examined the impact of task difficulty on interhemispheric communication and whether dividing identity related cognitive processing between both hemispheres was more beneficial to performance than constraining to one. The main findings indicate that both conceptual identity information and superficial image characteristics can be communicated across the hemispheres for familiar but not unfamiliar faces. Results of enquiries into the benefits of dividing processing between the hemispheres were somewhat inconclusive leading to an exploration of the impact of capacity limits for face processing on the experimental paradigm. Evidence that interhemispheric communication may occur asymmetrically in the direction of right hemisphere to left hemisphere was also obtained. Findings are discussed within the context of existing literature and theories examining the processes of interhemispheric communication.
Download or read book Hemispheric Asymmetry written by Joseph B. Hellige and published by Harvard University Press. This book was released on 2001 with total page 418 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: This volume contains the proceedings of a NATO Advanced Research Workshop (ARW) on the topic of "Changes in Speech and Face Processing in Infancy: A glimpse at Developmental Mechanisms of Cognition", which was held in Carry-Ie-Rouet (France) at the Vacanciel "La Calanque", from June 29 to July 3, 1992. For many years, developmental researchers have been systematically exploring what is concealed by the blooming and buzzing confusion (as William James described the infant's world). Much research has been carried out on the mechanisms by which organisms recognize and relate to their conspecifics, in particular with respect to language acquisition and face recognition. Given this background, it seems worthwhile to compare not only the conceptual advances made in these two domains, but also the methodological difficulties faced in each of them. In both domains, there is evidence of sophisticated abilities right from birth. Similarly, researchers in these domains have focused on whether the mechanisms underlying these early competences are modality-specific, object specific or otherwise.

Download or read book A Unified Hypothesis of Visual Asymmetry Interhemispheric Communication and Their Typical Development in Humans written by Benjamin N. Cipollini and published by . This book was released on 2014 with total page 230 pages. Available in PDF, EPUB and Kindle. Book excerpt: Lateralization is a part of virtually every function we think makes us human, yet there is no integrated neurophysiological explanation of the development of lateralization and interhemispheric integration. In this thesis I propose how development, lateralization in visual processing, and interhemispheric connectivity are all intertwined. I begin with evidence from neurocomputational modeling that lateralization in visual processing can be accounted for by a difference in the length of long-range lateral connections brought on by typical human developmental processes. The model can explain processing asymmetries for low vs. high spatial frequencies, local vs. global stimuli, as well as the right hemisphere lateralization of faces. Next, I show modeling evidence against the prevailing hypothesis that lateralization and interhemispheric communication are both functions of brain size. Previous papers have argued that lateralization is related to hemispheric independence which increases with brain size, due to both longer latency and proportionally fewer interhemispheric connections in larger brains. I examine interhemispheric connectivity across species using a new allometric analysis of existing data and examine latency effects through a re-analysis of neural network modeling data. Both results suggest that inter- hemispheric communication is robust across brain sizes. Along the way, I examine the neurophysiological development of long-range connections. I use neural network modeling to show that developmental changes in the physiology of axons may bias learning towards more local intrahemispheric circuits early in development, with long distance interhemispheric circuits becoming more prominent as connections mature. These modeling results are broadly consistent with the develop- mental trajectory of both interhemispheric communication and lateralization. I conclude by attempting to integrate these results into existing theories of developmental and adult visual lateralization. In many domains, communication is the key to the development of specialization. I hope this work can refocus our efforts to understand how interhemispheric communication affects the development of each lateralized function in the brain and treat any relationships between hemispheric independence and lateralization as an unexpected special case worth investigating further.

Download or read book Rhythms of the Brain written by G. Buzsáki and published by Oxford University Press. This book was released on 2011 with total page 465 pages. Available in PDF, EPUB and Kindle. Book excerpt: Studies of mechanisms in the brain that allow complicated things to happen in a coordinated fashion have produced some of the most spectacular discoveries in neuroscience. This book provides eloquent support for the idea that spontaneous neuron activity, far from being mere noise, is actually the source of our cognitive abilities. It takes a fresh look at the coevolution of structure and function in the mammalian brain, illustrating how self-emerged oscillatory timing is the brain's fundamental organizer of neuronal information. The small-world-like connectivity of the cerebral cortex allows for global computation on multiple spatial and temporal scales. The perpetual interactions among the multiple network oscillators keep cortical systems in a highly sensitive "metastable" state and provide energy-efficient synchronizing mechanisms via weak links. In a sequence of "cycles," György Buzsáki guides the reader from the physics of oscillations through neuronal assembly organization to complex cognitive processing and memory storage. His clear, fluid writing-accessible to any reader with some scientific knowledge-is supplemented by extensive footnotes and references that make it just as gratifying and instructive a read for the specialist. The coherent view of a single author who has been at the forefront of research in this exciting field, this volume is essential reading for anyone interested in our rapidly evolving understanding of the brain.
Download or read book The Integrated Mind written by Michael S. Gazzaniga and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 190 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Detailed chapters cover the many forms of therapy being explored to promote brain repair and consider clinical trial issues in this context. This book provides a summary of the neurobiology of innate and treatment-induced repair mechanisms after hypoxia and reviews the state of the art for human therapeutics in relation to promoting behavioral recovery after stroke. Essential reading for stroke physicians, neurologists, rehabilitation physicians and neuropsychologists.
Download or read book A Brain for Speech written by Francisco Aboitiz and published by Springer. This book was released on 2017-07-12 with total page 515 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book discusses evolution of the human brain, the origin of speech and language. It covers past and present perspectives on the contentious issue of the acquisition of the language capacity. Divided into two parts, this insightful work covers several characteristics of the human brain including the language-specific network, the size of the human brain, its lateralization of functions and interhemispheric integration, in particular the phonological loop. Aboitiz argues that it is the phonological loop that allowed us to increase our vocal memory capacity and to generate a shared semantic space that gave rise to modern language. The second part examines the neuroanatomy of the monkey brain, vocal learning birds like parrots, emergent evidence of vocal learning capacities in mammals, mirror neurons, and the ecological and social context in which speech evolved in our early ancestors. This book's interdisciplinary topic will appeal to scholars of psychology, neuroscience, linguistics, biology and history.
Download or read book Sex Differences in Cognitive Abilities written by Diane F. Halpern and published by Psychology Press. This book was released on 2000-02 with total page 439 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the third edition of her popular text, Sex Differences in Cognitive Abilities, Diane Halpern tackles fundamental questions about the meaning of sex differences in cognition and why people are so afraid of the differences. She provides a comprehensive context for understanding the theories and research on this controversial topic. The author employs the psychobiosocial model of cognition to negotiate a cease fire on the nature-nurture wars and offers a more holistic and integrative conceptualization of the forces that make people unique. This new edition reflects the explosion of theories and research in the area over the past several years. New techniques for peering into the human brain have changed the nature of the questions being asked and the kinds of answers that can be expected. There have been surprising new findings on the influence of sex hormones on cognitive abilities across the life span, as well as an increasing number of studies examining how attention paid to category variables such as one's sex, race, or age affects unconscious and automatic cognitive processes. Written in a clear, engaging style, this new edition takes a refreshing look at the science and politics of cognitive sex differences. Although it is a comprehensive and up-to-date synthesis of scientific theory and research into how, why, when, and to what extent females and males differ in intellectual abilities, it conveys complex ideas and interrelationships among variables in an engrossing and understandable manner, bridging the gap between sensationalized 'pop' literature and highly technical scientific journals. Halpern's thought-provoking perspectives on this controversial topic will be of interest to students and professionals alike. [features used for book mailer] FEATURES: *Includes new information about sex differences and similarities in the brain, the role of sex hormones on cognition (including exciting new work on hormone replacement therapy during menopause), new perspectives from evolutionary psychology, the way stereotypes and other group-based expectations unconsciously and automatically influence thought, the influence of pervasive sex-differentiated child rearing and other sex role effects, and understanding how research is conducted and interpreted. *Takes a cognitive process approach that examines similarities and differences in visuospatial working memory, verbal working memory, long-term acquisition and retrieval, sensation and perception, and other stages in information processing. *Provides a developmental analysis of sex differences and similarities in cognition extending from the early prenatal phase into very old age. *Tackles both political and scientific issues and explains how they influence each other--readers are warned that science is not value-free. *Uses cross-cultural data and warns readers about the limitations on conclusions that have not been assessed in multiple cultures. *Includes many new figures and tables that summarize complex issues and provide section reviews. It is a beautifully written book by a master teacher who really cares about presenting a clear and honest picture of contemporary psychology's most politicized topic.
