Download or read book Vision and the Brain written by Amanda Hall Lueck and published by AFB Press. This book was released on 2015-04 with total page 720 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cerebral visual impairment (also known as cortical visual impairment, or CVI) has become the most common cause of visual impairment in children in the United States and the developed world. Vision and the Brain is a unique and comprehensive sourcebook geared especially to professionals in the field of visual impairment, educators, and families who need to know more about the causes and types of CVI and the best practices for working with affected children. Expert contributors from many countries represent education, occupational therapy, orientation and mobility, ophthalmology, optometry, neuropsychology, psychology, and vision science, and include parents of children with CVI. The book provides an in-depth guide to current knowledge about brain-related vision loss in an accessible form to enable readers to recognize, understand, and assess the behavioral manifestations of damage to the visual brain and develop effective interventions based on identification of the spectrum of individual needs. Chapters are designed to help those working with children with CVI ascertain the nature and degree of visual impairment in each child, so that they can "see" and appreciate the world through the child's eyes and ensure that every child is served appropriately.
Download or read book Brain Vision Memory written by Charles G. Gross and published by MIT Press. This book was released on 1999-07-26 with total page 284 pages. Available in PDF, EPUB and Kindle. Book excerpt: In these engaging tales describing the growth of knowledge about the brain—from the early Egyptians and Greeks to the Dark Ages and the Renaissance to the present time—Gross attempts to answer the question of how the discipline of neuroscience evolved into its modern incarnation through the twists and turns of history. Charles G. Gross is an experimental neuroscientist who specializes in brain mechanisms in vision. He is also fascinated by the history of his field. In these tales describing the growth of knowledge about the brain from the early Egyptians and Greeks to the present time, he attempts to answer the question of how the discipline of neuroscience evolved into its modern incarnation through the twists and turns of history. The first essay tells the story of the visual cortex, from the first written mention of the brain by the Egyptians, to the philosophical and physiological studies by the Greeks, to the Dark Ages and the Renaissance, and finally, to the modern work of Hubel and Wiesel. The second essay focuses on Leonardo da Vinci's beautiful anatomical work on the brain and the eye: was Leonardo drawing the body observed, the body remembered, the body read about, or his own dissections? The third essay derives from the question of whether there can be a solely theoretical biology or biologist; it highlights the work of Emanuel Swedenborg, the eighteenth-century Swedish mystic who was two hundred years ahead of his time. The fourth essay entails a mystery: how did the largely ignored brain structure called the "hippocampus minor" come to be, and why was it so important in the controversies that swirled about Darwin's theories? The final essay describes the discovery of the visual functions of the temporal and parietal lobes. The author traces both developments to nineteenth-century observations of the effect of temporal and parietal lesions in monkeys—observations that were forgotten and subsequently rediscovered.

Book excerpt: An engaging introduction to the science of vision that offers a coherent account of vision based on general information processing principles In this accessible and engaging introduction to modern vision science, James Stone uses visual illusions to explore how the brain sees the world. Understanding vision, Stone argues, is not simply a question of knowing which neurons respond to particular visual features, but also requires a computational theory of vision. Stone draws together results from David Marr's computational framework, Barlow's efficient coding hypothesis, Bayesian inference, Shannon's information theory, and signal processing to construct a coherent account of vision that explains not only how the brain is fooled by particular visual illusions, but also why any biological or computer vision system should also be fooled by these illusions. This short text includes chapters on the eye and its evolution, how and why visual neurons from different species encode the retinal image in the same way, how information theory explains color aftereffects, how different visual cues provide depth information, how the imperfect visual information received by the eye and brain can be rescued by Bayesian inference, how different brain regions process visual information, and the bizarre perceptual consequences that result from damage to these brain regions. The tutorial style emphasizes key conceptual insights, rather than mathematical details, making the book accessible to the nonscientist and suitable for undergraduate or postgraduate study.

Book excerpt: Although we routinely take our vision to be veridical representations of reality, in actuality we choose (albeit unwittingly) or construct what we see. By movements of the eyes, the direction of our gaze, we create meaning. The author offers a reformulation of perception and its neural underpinnings, focusing on the active nature of perception. In his investigation of active perception and its brain mechanisms, he offers the gaze as the principal paradigm for perception. He discusses the dynamic and constrained nature of perception; the complex information processing at the level of the retina; the active nature of vision; the intensive nature of representations; the gaze of others as visual stimulus; and the intentionality of vision and consciousness.

Download or read book Vision Brain and Behavior in Birds written by Harris Philip Zeigler and published by MIT Press. This book was released on 1993 with total page 452 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides the first comprehensive and current review of considerable progress made over the past decade in analyzing neural and behavioral mechanisms mediating visually guided behavior in birds.The visual capacities of birds rival even those of primates, and their visual system probably reflects the operation of a ground plan common to all vertebrates. This book provides the first comprehensive and current review of considerable progress made over the past decade in analyzing neural and behavioral mechanisms mediating visually guided behavior in birds.The book's five major sections deal with the visual world of birds, the organization of avian visual systems, the development and plasticity of visual structure and function, visuomotor control mechanisms, and cognitive processes. The introduction to each section discusses the nature and significance of the problem areas, providing a context for the chapters to follow, which review the current status of research on a specific problem. The contributors are an international assemblage of researchers, representing a wide variety of disciplines, ranging from ornithology to neurophysiology and including ethology, experimental psychology, anatomy, and developmental neurobiology. For the ethologist, avian behavior is the source of a wide variety of species-typical fixed action patterns; for the experimental psychologist, birds are the subject of choice for studies of conditioning, learning, and cognitive processes; for the neurobiologist they provide model systems for studying developmental processes, sensory mechanisms, orientation, and motor control. For these reasons, research on the avian brain and behavior occupies an increasingly important place in contemporary behavioral biology.

The book contains their major papers from 1959 to 1981, each preceded and followed by comments telling how and why the authors went about the study, how the work was received, and what has happened since. It begins with short autobiographies of both men, and describes the state of the field when they started. It is intended not only for neurobiologists, but for anyone interested in how the brain works-biologists, psychologists, philosophers, physicists, historians of science, and students at all levels from high school to graduate level.
Download or read book Discovering the Brain written by National Academy of Sciences and published by National Academies Press. This book was released on 1992-01-01 with total page 195 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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."

Download or read book Making Eye Health a Population Health Imperative written by National Academies of Sciences, Engineering, and Medicine and published by National Academies Press. This book was released on 2017-01-15 with total page 587 pages. Available in PDF, EPUB and Kindle. Book excerpt: The ability to see deeply affects how human beings perceive and interpret the world around them. For most people, eyesight is part of everyday communication, social activities, educational and professional pursuits, the care of others, and the maintenance of personal health, independence, and mobility. Functioning eyes and vision system can reduce an adult's risk of chronic health conditions, death, falls and injuries, social isolation, depression, and other psychological problems. In children, properly maintained eye and vision health contributes to a child's social development, academic achievement, and better health across the lifespan. The public generally recognizes its reliance on sight and fears its loss, but emphasis on eye and vision health, in general, has not been integrated into daily life to the same extent as other health promotion activities, such as teeth brushing; hand washing; physical and mental exercise; and various injury prevention behaviors. A larger population health approach is needed to engage a wide range of stakeholders in coordinated efforts that can sustain the scope of behavior change. The shaping of socioeconomic environments can eventually lead to new social norms that promote eye and vision health. Making Eye Health a Population Health Imperative: Vision for Tomorrow proposes a new population-centered framework to guide action and coordination among various, and sometimes competing, stakeholders in pursuit of improved eye and vision health and health equity in the United States. Building on the momentum of previous public health efforts, this report also introduces a model for action that highlights different levels of prevention activities across a range of stakeholders and provides specific examples of how population health strategies can be translated into cohesive areas for action at federal, state, and local levels.
Download or read book The Mind s Eye written by Oliver Sacks and published by Vintage. This book was released on 2010-10-26 with total page 261 pages. Available in PDF, EPUB and Kindle. Book excerpt: NATIONAL BESTSELLER • From “the poet laureate of medicine" (The New York Times) and the author of the classic The Man Who Mistook his Wife for a Hat comes a fascinating exploration of the remarkable, unpredictable ways that our brains cope with the loss of sight by finding rich new forms of perception. “Elaborate and gorgeously detailed.... Again and again, Sacks invites readers to imagine their way into minds unlike their own, encouraging a radical form of empathy.” —Los Angeles Times With compassion and insight, Dr. Oliver Sacks again illuminates the mysteries of the brain by introducing us to some remarkable characters, including Pat, who remains a vivacious communicator despite the stroke that deprives her of speech, and Howard, a novelist who loses the ability to read. Sacks investigates those who can see perfectly well but are unable to recognize faces, even those of their own children. He describes totally blind people who navigate by touch and smell; and others who, ironically, become hyper-visual. Finally, he recounts his own battle with an eye tumor and the strange visual symptoms it caused. As he has done in classics like The Man Who Mistook his Wife for a Hat and Awakenings, Dr. Sacks shows us that medicine is both an art and a science, and that our ability to imagine what it is to see with another person's mind is what makes us truly human.

Download or read book Vision Rehabilitation written by Penelope S. Suter and published by CRC Press. This book was released on 2016-04-19 with total page 544 pages. Available in PDF, EPUB and Kindle. Book excerpt: Providing the information required to understand, advocate for, and supply post-acute vision rehabilitative care following brain injury, Vision Rehabilitation: Multidisciplinary Care of the Patient Following Brain Injury bridges the gap between theory and practice. It presents clinical information and scientific literature supporting the diagnostic and therapeutic strategies applied in a comprehensive overview of current diagnostic and treatment strategies in adult post-brain injury vision rehabilitation. Includes a foreword by Dr. Sue Barry Because post-brain injury rehabilitation works best in a team setting where the entire person can be treated, this text has been carefully designed as a multidisciplinary resource with an emphasis on models for working with the rehabilitation team. The book covers a myriad of topics such as post-brain injury vision rehabilitation; eye movements; binocular dysfunction; visual field loss; visual-spatial neglect; shifts in visual egocenter affecting balance and coordination; visual-vestibular interactions; central vs. peripheral visual attention; as well as deficits in object perception, visual memory, and visual cognition. The book details models that vision specialists working with the rehabilitation team can use to achieve the best success for the patient in rehabilitation; vision rehabilitation concepts and the science from which they have been developed; examples of therapeutic exercises; practice management information for the post-brain injury vision rehabilitation practice; and information on the legal process in which one frequently becomes involved in this type of work. Edited by eminent clinicians, the book highlights the work of contributors who are well-respected academicians and researchers, bringing together the clinical information that enables everyone involved in a brain injury case to grasp the diagnostic and therapeutic strategies.
Download or read book Vision and Mind written by Alva Noë and published by MIT Press. This book was released on 2002-10-25 with total page 644 pages. Available in PDF, EPUB and Kindle. Book excerpt: The philosophy of perception is a microcosm of the metaphysics of mind. Its central problems—What is perception? What is the nature of perceptual consciousness? How can one fit an account of perceptual experience into a broader account of the nature of the mind and the world?—are at the heart of metaphysics. Rather than try to cover all of the many strands in the philosophy of perception, this book focuses on a particular orthodoxy about the nature of visual perception. The central problem for visual science has been to explain how the brain bridges the gap between what is given to the visual system and what is actually experienced by the perceiver. The orthodox view of perception is that it is a process whereby the brain, or a dedicated subsystem of the brain, builds up representations of relevant figures of the environment on the basis of information encoded by the sensory receptors. Most adherents of the orthodox view also believe that for every conscious perceptual state of the subject, there is a particular set of neurons whose activities are sufficient for the occurrence of that state. Some of the essays in this book defend the orthodoxy; most criticize it; and some propose alternatives to it. Many of the essays are classics. Contributors G.E.M. Anscombe, Dana Ballard, Daniel Dennett, Fred Dretske, Jerry Fodor, H.P. Grice, David Marr, Maurice Merleau-Ponty, Zenon Pylyshyn, Paul Snowdon, and P.F. Strawson

This book was released on 2010-09-14 with total page 369 pages. Available in PDF, EPUB and Kindle. Book excerpt: Clinics in Developmental Medicine No.186 The increased awareness of cerebral visual impairment in children, combined with improved recognition of its wide ranging manifestations, has led to its recognition as the most common cause of visual impairment in children in the developed world. Yet the subject is in its infancy, with very little published to date. Information on this complex topic has been needed by all disciplines working with disabled children for many years. This ambitious book links the work of authors from many of the major research teams in this field, who have made significant contributions to the literature on the subject of cerebral visual impairment and provide a structured amalgam of the viewpoints of different specialists. The book contains some very novel concepts, which will be of great practical value to those who care for children with visual impairment due to brain injury. Summaries of the more specialist chapters as well as clear diagrams and a glossary have been provided to increase the book’s accessibility to a broader readership. This is an exciting and important field, to which this book makes a major contribution.
