The vertebrate eye has been, and continues to be, an object of interest and of inquiry for biologists, physicists, chemists, psychologists, and others. Quite apart from its important role in the development of ophthalmology and related medical disciplines, the vertebrate eye is an exemplar of the ingenuity of living systems in adapting to the diverse and changing environments in which vertebrates have evolved. The wonder is not so much that the visual system, like other body systems, has been able to adapt in this way, but rather that these adaptations have taken such a variety of forms. In a previous volume in this series (VII/I) Eakin expressed admiration for the diversity of invertebrate photoreceptors. A comparable situation exists for the vertebrate eye as a whole and one object of this volume is to present to the reader the nature of this diversity. One result of this diversification of ocular structures and properties is that the experimental biologist has available a number of systems for study that are unique or especially favorable for the investigation of particular questions in visual science or neurobiology. This volume includes some examples of progress made by the use of such specially selected vertebrate systems. It is our hope that this comparative approach will continue to reveal new and useful preparations for the examination of important questions.

A question often asked of those of us who work in the seemingly esoteric field of fish vision is, why? To some of us the answer seems obvious - how many other visual scientists get to dive in a tropical lagoon in the name of science and then are able to eat their subjects for dinner? However, there are better, or at least scientifically more acceptable, reasons for working on the visual system of fish. First, in terms of numbers, fish are by far the most important of all vertebrate classes, probably accounting for over half (c. 22 000 species) of all recognized vertebrate species (Nelson, 1984). Furthermore, many of these are of commercial importance. Secondly, if one of the research aims is to understand the human visual system, animals such as fish can tell us a great deal, since in many ways their visual systems, and specifically their eyes, are similar to our own. This is fortunate, since there are several techniques, such as intracellular retinal recording, which are vital to our understanding of the visual process, that cannot be performed routinely on primates. The cold blooded fish, on the other hand, is an ideal subject for such studies and much of what we know about, for example, the fundamentals of information processing in the retina is based on work carried out on fish (e. g. Svaetichin, 1953).

When Dr. Katherine Tansley's "Vision in Vertebrates" appeared in 1965, it filled a real void that had hitherto existed. It did so by serving at once as a text-book: for an undergraduate course, a general introduction to the subject for post-graduate students embarking on research on some aspect of vision, and the interested non-specialists. Gordon Walls' "The Vertebrate Eye and It. s Adaptive Radiation" and A. Rochon-Duvigneaud's "Les Yeux et la Vision des Vertebres" have served as important sources of information on the subject and continue to do so even though it is 40 years since they appeared. However, they are essentially specialised reference works and are not easily accessible to boot. The genius of Katherine Tansley was to present in a succinct (132 pages) and lucid way a clear and an interesting survey of the matter. Everyone liked it, particularly the students because one could read it quickly and understand it. Thus, when it seemed that a new edition was desirable, especially in view of the enormous strides made and the vast literature that had accumulated in the past 20 years, one of us (MAA) asked Dr. Tansley if she would undertake the task. Since she is in retirement and her health not in a very satisfactory state both she and her son, John Lythgoe (himself a specialist of vision), asked us to take over the task.

In the domain of form recognition the human visual system surpasses by far the capacity of actually existing technical devices designed to serve the same purpose. Therefore it appears advantageous to undertake a communication-theoretic function-description and structure-description of the biological system in order to gain suggestions for the solution of technical problems and in order to make possible the adaptation of technical apparatus to human beings. Over and above this an understanding of visual information processing will probably permit inferences to be drawn regarding the functioning of fairly large parts of the brain since the information picked up by the peripheral sense organs is processed in similarly structured networks in the cerebrum. The following investigation is based essentially on the electrophysiological studies of Hubel and Wiesel on the visual cortex of cats and monkeys. (Author).

Development of the Visual System presents a selection of current studies that clearly illustrate principles of visual system development. These range from retinal development in fish and frogs to the effects of abnormal visual experience on the primary visual cortex of the cat. The book is unique in addressing four specific and fundamental aspects of development: cell lineage and cell fate, specificity and targeting of axons, specification of visual cortex, and correlates of the critical period. Encompassing technical advances in cellular and molecular biology and in video imaging and microscopy, contributions in each of these areas provide new information at the cellular and molecular levels to complement the now classic descriptions of visual development previously available at the level of neural systems.ContributorsKaren L.

'Vision and the Visual System' offers students, teachers and researchers a rigorous, yet accessible account of how the brain analyses the visual scene. Schiller and Tehovnik describe key aspects of visual perception such as colour, motion, pattern and depth while explaining the relationship between eye movements and neural structures in the brain.
