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.

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.

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.

Book Description
This volume contains chapters derived from a N. A. T. O. Advanced Study Institute held in June 1983. As the director of this A. S. I. it was my hope that some of the e1ectrophysiologists could express the potentialities of their work for perceptual theory, and that some perceptionists could speculate on the underlying "units" of perception in a way that would engage the imagination of physio logists. The reader will have to be the judge of whether this was achieved, or whether such a psychophysiological inter1ingua is still overly idealistic. It is clear that after the revolution prec~pitated by Hube1 and Weisel in understanding of visual cortical neurons we still have only a foggy idea of the behavioral output of any particular species of cortical detector. It was therefore particularly unfortunate that two persons who have made great strides in correlating interesting facets of cat cortical physio logy with human psychophysics (Max Cynader and Martin Regan of Dalhousie University) were unable to attend this meeting. Never theless, a number of new and challenging ideas regarding both spatial perception and cortical mechanisms are represented in this volume, and it is hoped that the reader will remember not only the individual demonstrations but the critical questions posed by the apposition of the two different collections of experimental facts.

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.

Book Description
Internationally renowned researchers discuss how the various parts of the brain process and integrate visual signals, providing up to date original findings, reviews, and theoretical proposals on visual processing. This book addresses the basic mechanisms of visual perception as well as issues such as neuronal plasticity, functional reorganization and recovery, residual vision, and sensory substitution. Knowledge of the basic mechanisms by which our brain can analyze, reconstruct, and interpret images in the external world is of fundamental importance for our capacity to understand the nature and causes of visual deficits, such as those resulting from ischemia, abnormal development, neuro-degenerative disorders, and normal aging. It is also essential to our goal of developing better therapeutic strategies, such as early diagnosis, visual training, behavioral rehabilitation of visual functions, and visual implants.
