This book provides a series of comprehensive views on various important aspects of vertebrate photoreceptors. The vertebrate retina is a tissue that provides unique experimental advantages to neuroscientists. Photoreceptor neurons are abundant in this tissue and they are readily identifiable and easily isolated. These features make them an outstanding model for studying neuronal mechanisms of signal transduction, adaptation, synaptic transmission, development, differentiation, diseases and regeneration. Thanks to recent advances in genetic analysis, it also is possible to link biochemical and physiological investigations to understand the molecular mechanisms of vertebrate photoreceptors within a functioning retina in a living animal. Photoreceptors are the most deeply studied sensory receptor cells, but readers will find that many important questions remain. We still do not know how photoreceptors, visual pigments and their signaling pathways evolved, how they were generated and how they are maintained. This book will make clear what is known and what is not known. The chapters are selected from fields of studies that have contributed to a broad understanding of the birth, development, structure, function and death of photoreceptor neurons. The underlying common word in all of the chapters that is used to describe these mechanisms is “molecule”. Only with this word can we understand how these highly specific neurons function and survive. It is challenging for even the foremost researchers to cover all aspects of the subject. Understanding photoreceptors from several different points of view that share a molecular perspective will provide readers with a useful interdisciplinary perspective.

Excerpt from Vertebrate Photoreceptors The structure of the vertebrate retina in relation to its function is a subject about which much has been written. It might seem redundant, therefore, to add to the voluminous literature already extant. This is especially true in view of the recent appearance of two excellent books on the subject. The first of these, by S. L. Polyak, appeared in October 1941, while my writing was in progress; the second by G. L. Walls, which was published in August 1942, did not appear until after my manuscript had gone to the publishers. Despite the admirable and comprehensive accounts by these two authors, as well as previous shorter accounts by other writers (cajal, 1894; Greeff, 1900; Garten, 1907; Franz, 1913; Arey, 1928; Kolmer, 1936 and others), I have been urged by my colleagues to finish my story, with the assurance that this monograph would adequately fulfill its originally intended purpose as a handbook for those interested in the visual apparatus of vertebrates. It has been my plan to bring together in this volume cer tain essential structural and functional features of the retina, particularly of the photoreceptors. It has not been my pur pose to enter into the minutiae of histological detail, for this would befog my original point of view which has been to present an account of the retinal photoreceptors in such a form as to be of value to those who have a general interest in the biology of the retina, rather than to the specialist. It is hoped, however, that it may be of definite service also to those more specifically concerned with problems of retinal physiology.

Invertebrate Photoreceptors: A Comparative Analysis covers the structure and pigment chemistry of invertebrate photoreceptors. The book discusses the photobehavior and photoreceptor systems of invertebrate animals; the protozoan photoreceptor; and the compound eye. The text also describes the crustacean and mollusc eyes; the vertebrate retinal photoreceptors; and the invertebrate eye and its visual pigments. The book concludes with discussions on primitive photoreceptors; spectral sensitivity, pigments, and color vision; and polarized light analysis. Biologists and people involved in the study of invertebrate photobiology will find the text invaluable.

This volume is a collection of essays which attempts to summarize the recent progress in the field of photoreceptor and retinal physiology. Reflecting the way in which research is organized, each author reports on the studies performed with the techniques with which he is most familiar: morpholo gical, chemical or physiological. The first chapters describe the structure of visual cells and the histological architecture of the retina. Next comes a summary of the laws governing photochemical reactions and a report on the biochemistry of photopigments. Four articles cover the optical properties of invertebrate eyes and the electrophysiology and the interactions of their photoreceptors. These are followed by a discussion of the properties of vertebrate eyes, including chapters on optics, on the electrical responses of rods and cones and on the functional organization of the retina. The final chapter provides an extensive review of retinal biochemistry and metabolism. Even though the experimental approach differs, all studies are directed toward the solution of two basic problems: transduction in the photoreceptors and orga nization (often called "information processing") in the retina. The central problem of photoreceptor cells is to determine how light produces a response. We know that illumination evokes electrical changes and we have recently learned a great deal about the features of these changes. The evidence indicates however that elaborate processes must be interposed between the ab sorption of photons by the pigment and the production of electric currents through the membrane. These intermediary cvents remain to be unraveled.

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.
