Book Description
The International Society for Clinical Electroretinography provides a link between scientists who are enlarging our understanding of the normal functioning of the visual pathway, and clinicians who investigate and treat visual disturbances. The chief function of the Society is to organise symposia, where, with skill born of long practice, the participants obtain the benefits of both social and scientific contact, without detriment to either. The result ing spread of information is documented both in the society's Newsletter, and by the publication of volumes such as this, the record of the 9th Symposium held at Brighton in 1971. This meeting was a joint Symposium of the ISCERG and the International Union of Physiological Sciences. The subjects covered represent merely the interests of the organisers. The biophysical studies are represented by chapters on such divers topics as the x-ray diffraction of receptor membranes and impedance properties of outer limb suspensions. Other papers deal with the problems of maintaining the retina in vitro in a physiological condition. Papers describing techniques for investigating the functional properties of the visual system shade into those which describe new aspects of human disease. In the past such serendipity has been of value as evidenced by compal-ison between this and previous volumes. In 1965 the physiological section of the Proceedings was largely devoted to a new elec trical response, the evoked potential of the visual cortex.

Book Description
This book presents an interdisciplinary overview of the main facts and theories that guide contemporary research on visual perception. While the chapters cover virtually all areas of visual science, from philosophical foundations to computational algorithms, and from photoreceptor processes to neuronal networks, no attempt has been made to provide an exhaustive treatment of these topics. Rather, researchers from such diverse disciplines as psychology, neurophysiology, anatomy, and clinical vision sciences have worked together to review some of the most important correlations between perceptual phenomena and the underlying neurophysiological processes and mechanisms. The book is thus intended to serve as an advanced text for graduate students and as a guide for all vision researchers to understanding current progress outside their specialized fields of interest.ï Examines parallel processing of visual informationï Discusses links between physiologically-measured receptive fields and psychophysically-measured perceptive fieldsï Presents a spatial sampling by the retina and cortical modulesï Covers signal transduction and the sites of adaptationï Describes a single-cell analysis of attentionï Discusses computational models of vision

Book Description
Visual Psychophysics and Physiology: A Volume Dedicated to Lorrin Riggs illustrates a particular approach to the study of vision. It also celebrates Lorrin Riggs' retirement from formal teaching duties. During his teaching career Riggs advised and directed about fifty doctoral and postdoctoral students, many of whom wrote the chapters that make up this volume. The book is organized into six parts. Part 1 explains the approach to the study of vision, thus providing the philosophical theme for the chapters that follow. Part 2 on physiological mechanisms presents examples of comparative and physiological investigations. Part 3 on sensitivity and adaptation examines new research that bears directly upon the classical problems of visual psychophysics. Here, there is an initial concern with measurement, visual sensitivity, scaling, and adaptation. Part 4 discusses research on color vision while Part 5 on acuity, contrast, and movement considers some of the factors that contribute to these perceptions. Part 6 deals with applications of visual science to other disciplines. Specific examples are given that link visual research with ophthalmology, child development, and the investigation of cognitive variables such as meaning, activation, and so forth.

Book Description
Converging lines of biological, perceptual and theoretical approaches are brought together in The Science of Vision to give a new perspective on the brain sciences and vision in particular. The book contains contributions from experts in the fields of biophysics, physiology, psychology and computation. While reviewing some basic knowledge, it mainly presents fresh ideas and includes some new results. The topics range from cells through perception to neurocomputing and are treated in depth, taking the specialist to the frontiers of research. At the same time the book is written in a manner understandable to the nonspecialist, in keeping with the multidisciplinary appeal of the subject. A glossary of terms also makes the book easy to read. In our age of specialization, this integrated approach is a welcome addition to the literature which will further interdisciplinary research and shed new light on the vision sciences.

Book Description
This volume on Visual Psychophysics documents the current status of research aimed toward understanding the intricacies of the visual mechanism and its laws of operation in intact human perceivers. As can be seen from the list of contributors, the problems of vision engage the interest and experimental ingenuity of investi gators from a variety of disciplines. Thus we find authors affiliated with depart ments of biology, medical and physiological physics, ophthalmology, physics, physiology and anatomy, psychology, laboratories of neurophysiology, medical clinics, schools of optometry, visual and othcr types of research institutes. A continuing interplay between psychophysical studies and physiological work is everywhere evident. As more information about the physiological basis of vision accumulates, and new studies and analyses of receptor photochemistry and the neurophysiology of retina and brain appear, psychophysical studies of the intact organism become more sharply focused, sometimes more complex, and often more specialized. Technological advances have increased the variety and precision of the stimulus controls, and advances in measurement techniques have reopened old problems and stimulated the investigation of new ones. In some cases, new concepts are being drawn in to help further our under standing of the laws by which the visual mechanism operates; in other cases, ideas enunciated long ago have been reevaluated, developed more fully, and reified in terms of converging evidence from both psychophysical experiments and unit recordings from visual cells.

Book Description
Published by Freund Publishing House Ltd. Suite 500, Chesham House, 150 Regent Street, London, W1R 5FA, England. Contains edited articles, mostly from the 12th European Conference on Visual Perception (ECVP) held at Zichron Yaacov, Israel in 1989. While the subject is the proceeding of visual information from the receptor up to the perceptual and the conceptual level, material is oriented towards the long lasting concept of "channels" in the visual nervous system. "Channels" are covered from all points of view, including those that find the concept useful as well a those that criticize it. Annotation copyrighted by Book News, Inc., Portland, OR

Book Description
A comprehensive treatment of the skills and techniques needed for visual psychophysics, from basic tools to sophisticated data analysis. Vision is one of the most active areas in biomedical research, and visual psychophysical techniques are a foundational methodology for this research enterprise. Visual psychophysics, which studies the relationship between the physical world and human behavior, is a classical field of study that has widespread applications in modern vision science. Bridging the gap between theory and practice, this textbook provides a comprehensive treatment of visual psychophysics, teaching not only basic techniques but also sophisticated data analysis methodologies and theoretical approaches. It begins with practical information about setting up a vision lab and goes on to discuss the creation, manipulation, and display of visual images; timing and integration of displays with measurements of brain activities and other relevant techniques; experimental designs; estimation of behavioral functions; and examples of psychophysics in applied and clinical settings. The book's treatment of experimental designs presents the most commonly used psychophysical paradigms, theory-driven psychophysical experiments, and the analysis of these procedures in a signal-detection theory framework. The book discusses the theoretical underpinnings of data analysis and scientific interpretation, presenting data analysis techniques that include model fitting, model comparison, and a general framework for optimized adaptive testing methods. It includes many sample programs in Matlab with functions from Psychtoolbox, a free toolbox for real-time experimental control. Once students and researchers have mastered the material in this book, they will have the skills to apply visual psychophysics to cutting-edge vision science.
