Book Description
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.

Pages : 284

Book Description
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.

Brain and the Gaze

ISBN: 0262017911
Category : Health & Fitness
Languages : en
Pages : 313

Book Description
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.

Vision and Brain

ISBN: 0262517736
Category : Psychology
Languages : en
Pages : 275

Book Description
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.

Vision, Brain, and Behavior in Birds

Author: Harris Philip Zeigler
Publisher: MIT Press
ISBN: 9780262240369
Category : Birds
Languages : en
Pages : 452

Book Description
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.

Languages : en
Pages : 544

Book Description
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.

Book Description
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.
