The present volume was assembled in honor of Professor Alan Cowey FRS, and attempts to embrace his wide range of research interests in visual neuroscience. It is divided into four sections.

The first contains a group of papers dealing with different fundamental aspects of the visual system, including the control and monitoring of eye movements. The second is concerned with the functional organization of cortical visual areas and their role in visual perception and visually guided action. The third addresses issues concerning color and motion perception, along with broader questions of...

This is an extensive collection of essays on all aspects of vision, approached from the perspective of coding and efficiency. It examines the broad spectrum of vision research from one particular, unifying viewpoint, namely the way that visual systems efficiently encode and represent the outside world. This approach, both rigorous and general, was championed by H.B. Barlow in the fifties and has been followed in many areas of vision research. The approach has recently acquired new significance due to the growing interest of computer science and artificial intelligence in the processes of...
