The advent of sensors capable of localizing portions of the brain involved in specific computations has provided significant insights into normal visual information processing and specific neurological conditions. Aided by devices such as fMRI, researchers are now able to construct highly detailed models of how the brain processes specific patterns of visual information. This book brings together some of the strongest thinkers in this field, to explore cortical visual information processing and its underlying mechanisms. It is an excellent resource for vision researchers with both biological and computational backgrounds, and is an essential guide for graduate students just starting out in the field.

This volume is based on the Symposium on "The Brain and Human Behavior," held in October of 1969 as a part of the centennial observance of the Loyola Uni versity of Chicago. As President of the University, I was pleased to offer the University's support for the organization of this Symposium and to participate in some of its sessions. The volume which I now have the pleasure to introduce employs the materials of the Symposium as a framework. Its chapters constitute updated and greatly expanded versions of the original presentations, edited and organized so as to constitute an integrated picture of Neurosciences and their epistemological aspects. It seems appropriate for me to describe at this time certain features of this Jesuit University and of its Centennial which are particularly pertinent in the context of the present volume. Loyola University of Chicago opened its classes on September 5, 1870 with a faculty of 4 and a student body of 37. Today, Loyola University is the largest in dependent University in Illinois and the largest institution of higher learning under Catholic sponsorship in the United States of America. The University comprises twelve schools and colleges, a faculty of more than 1,600 and a student body of 16,545. As an institution of learning, this University is dedicated to knowledge; but perhaps more particularly than others, it is dedicated to the integration of truth and the knowledge of man as such.

From the Foreword by Nobel Laureate David Hubel: "We now have the first clear demonstration of double opponent cells in the primate visual system. Given the temperament of those who work in the field of color vision there seems little doubt that heated debates will continue, but for the present at least, the subject seems to be as close to settled as such things can be in science." How the brain represents color remains one of the most controversial topics in neurophysiology. We know that color is represented through an opponent mechanism, demonstrated by the fact that some colors are exclusive of others. Yet how these antagonistic chromatic axes are represented in the cortex has been a mystery. 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.

The world is not always truly reflected in what we see. The brain creates images, fills in gaps and even at times constructs fictions. This book brings together experts from several diverse fields to present state of the art accounts of how the visual world enters two small holes in our heads and is reconstructed to give us the rich impressions of color, movement, and shape.

Evolution of Nervous Systems, Second Edition, Four Volume Set is a unique, major reference which offers the gold standard for those interested both in evolution and nervous systems. All biology only makes sense when seen in the light of evolution, and this is especially true for the nervous system. All animals have nervous systems that mediate their behaviors, many of them species specific, yet these nervous systems all evolved from the simple nervous system of a common ancestor. To understand these nervous systems, we need to know how they vary and how this variation emerged in evolution. In the first edition of this important reference work, over 100 distinguished neuroscientists assembled the current state-of-the-art knowledge on how nervous systems have evolved throughout the animal kingdom. This second edition remains rich in detail and broad in scope, outlining the changes in brain and nervous system organization that occurred from the first invertebrates and vertebrates, to present day fishes, reptiles, birds, mammals, and especially primates, including humans. The book also includes wholly new content, fully updating the chapters in the previous edition and offering brand new content on current developments in the field. Each of the volumes has been carefully restructured to offer expanded coverage of non-mammalian taxa, mammals, primates, and the human nervous system. The basic principles of brain evolution are discussed, as are mechanisms of change. The reader can select from chapters on highly specific topics or those that provide an overview of current thinking and approaches, making this an indispensable work for students and researchers alike. Presents a broad range of topics, ranging from genetic control of development in invertebrates, to human cognition, offering a one-stop resource for the evolution of nervous systems throughout the animal kingdom Incorporates the expertise of over 100 outstanding investigators who provide their conclusions in the context of the latest experimental results Presents areas of disagreement and consensus views that provide a holistic view of the subjects under discussion
