Book Description
Dr. Conway mapped the spatial and temporal structure of the cone inputs to single neurons in the primary visual cortex of the alert macaque. Color cells had receptive fields that were often Double-Opponent, an organization of spatial and chromatic opponency sufficient to form the basis for color constancy and spatial color contrast. Almost all color cells gave a bigger response to color when preceded by an opposite color, suggesting that these cells also encode temporal color contrast. In sum, color perception is likely subserved by a subset of specialized neurons in the primary visual cortex. These cells are distinct from those that likely underlie form and motion perception. Color cells establish three color axes sufficient to describe all colors; moreover these cells are capable of computing spatial and temporal color contrast - and probably contribute to color constancy computations - because the receptive fields of these cells show spatial and temporal chromatic opponency.

Book Description
Visual illusions cut across academic divides and popular interests: on the one hand, illusions provide entertainment as curious tricks of the eye; on the other hand, scientific research related to illusory phenomena has given generations of scientists and artists deep insights into the brain and principles of mind and consciousness. Numerous thinkers (including Aristotle, Descartes, Da Vinci, Escher, Goethe, Galileo, Helmholtz, Maxwell, Newton, and Wittgenstein) have been lured by the apparent simplicity of illusions and the promise that illusory phenomena can elucidate the puzzling relationship between the physical world and our perceptual reality. Over the past thirty years, advances in imaging and electrophysiology has dramatically expanded the range of illusions and enabled new forms of analysis, thereby creating new and exciting ways to consider how the brain constructs our perceptual world. The Oxford Compendium of Visual Illusions is a collection of over one hundred chapters about illusions, displayed and discussed by the researchers who invented and conducted research on the illusions. Chapters include full-color images, associated videos, and extensive references. The book is divided into eleven sections: first, a presentation of general history and viewpoints on illusions, followed by sections on geometric, color, motion, space, faces, and cross-category illusions. The book will be of interest to vision scientists, neuroscientists, psychologists, physicists, philosophers, artists, designers, advertisers, and educators curious about applied aspects of visual perception and the brain.

Book Description
The papers published in this Volume are the fruits of a symposium held in Regensburg in April 1987. The meeting was held to com memorate two most significant events in the development of com pound eye research. In chronological order these are firstly, Sigmund Exner's seminal monograph on the physiology of compound eyes of crustaceans and insects, which was first published in Vienna in 1891, and is now shortly to appear for the first time in the English translation [Exner, S. (1989) The Physiology of the Compound Eyes of Insects and Crustaceans. Springer Berlin Heidelberg New York Tokyo]. Secondly, the meeting was also held in honour of Professor Hansjochem Autrum's 80th birthday. Professor Autrum, who is justly acknowledged as one of the pioneers of modern compound eye research, attended the meeting as the guest of honour. In keeping with these historical occasions, it has been our intention in this volume to present a comprehensive collection of short reviews covering the major aspects of compound eye research. Whilst the most up-to-date developments have been included in every field from optics, through photochemistry, phototransduction, integrative processes and behavior, an attempt has also been made to provide a historical perspective.

Book Description
Thompson provides an accessible review of the current scientific and philosophical discussions of colour vision and is vital reading for all cognitive scientists and philosophers whose interests touch upon this central area.Colour fascinates all of us, and scientists and philosophers have sought to understand the true nature of colour vision for many years. In recent times, investigations into colour vision have been one of the success stories of cognitive science, for each discipline within the field - neuroscience, psychology, linguistics, computer science and artificial intelligence, and philosophy - has contributed significantly to our understanding of colour. Evan Thompson's book is a major contribution to this interdisciplinary project.Colour Vision provides an accessible review of the current scientific and philosophical discussions of colour vision. Thompson steers a course between the subjective and objective positions on colour, arguing for a relational account. This account develops a novel 'ecological' approach to colour vision in cognitive science and the philosophy of perception. It is vital reading for all cognitive scientists and philosophers whose interests touch upon this central area.

Book Description
In this textbook on the physiology of vision, Buser and Imbert synthesize the data in the field, proceeding from the biophysics of retinal receptors to processing in the visual areas of the cortex. Although the focus is on mammalian studies, some data from comparative physiology are included. In just five chapters the authors cover the structure and organization of the retina, the physical characteristics of visual stimuli, the psychophysical laws of visual sensation (absolute thresholds, retinal adaptation, visual acuity, temporal resolution, movement perception, color vision, and stereopsis), the genesis and elaboration of signals in the retina, and mechanisms in the central visual pathways. Like Buser and Imbert's companion sensory neurophysiology text Audition, Vision has been translated and updated from the original French in a style that is straightforward and concise. It includes 248 carefully chosen and fully captioned illustrations that will make it accessible to upper-level undergraduate and graduate students in the basic and clinical neurosciences, to students in courses on perception and psychophysics in psychology departments, as well as to researchers in computer vision who are interested in biological vision..
