DOWNLOAD EBOOKThe mechanism by which photoreceptor cells in the eyes of higher animals absorb light, giving rise to receptor potentials that initiate the visual process, is a subject of active research in biophysics today. The pace of this research and its multidisciplinary nature have made it difficult for the nonexpert to keep abreast of new discoveries. This book aims to provide a more coherent, compact summary of our knowledge about the field that has been available, serving as an up-to-date introduction to the role of photoreceptors in vision. The book is a self-contained, concise handbook for the reader who has at least a college level knowledge if cell biology, biochemistry, physical chemistry, neurobiology and physics. The authors describe the physical parameters of light and proceed to describe the mechanisms by which photoreceptors extract information about each parameter. The discussion of mechanisms is organized by discipline, following the general sequence of cellular morphology, visual pigment chemistery, and receptor physiology. Photoreceptors: their role in vision is an integrated sourcebook which will serve the novice as a 'stepping stone' to the vast and exciting scientific literature of the field.

DOWNLOAD EBOOKThis 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.

DOWNLOAD EBOOKThis book offers comprehensive coverage of the most important areas in photoreceptors and light signalling. Photoreceptors enable most species to sense not only the presence of light but also the information, such as irradiance, colour or spectral distribution, direction and polarization of light. They are vital, therefore, in providing organisms with energy and information about their surroundings, such as day and night cycles. This book covers the range of photoreceptors that have been discovered to date and the broad range of methods used when researching how they operate, including: action spectroscopy; methods for protein purification; the whole range of molecular biological and genetic methods; and numerous spectroscopic methods, from absorption and fluorescence spectroscopy to X-ray diffraction, used for solving the structure of photoreceptors. Written by leading experts in the field, Photoreceptors and Light Signalling provides the reader with the most recent results and research. This book will be valued by a wide-range of readers, including students of photochemistry, photobiology, biology, chemistry and physics and other professionals in academia.

DOWNLOAD EBOOKThis volume foxuses on the status of Ca2+ ions in regulation of phototransduction, light adaptation and the recovery phase in vertebrate photoreceptors. Particular emphasis is given to Ca2+-binding proteins and their targets, among them particulate guanylate cyclases, GPCR-coupled kinases and cyclic nucleotide-gated cation channels. The book also expands our understanding of events invovling Ca2+ in the retinal pigment epithelium, in synaptic transmission and secondary retinal neurons. A significant part of the book is dedicated to the role of Ca2+ in invertebrate phototransduction, the best-studied phospholipid-mediated signal transduction pathway. Several chapters explore association of gene defects with human retina disease and the generation of animal models of retinal degeneration.
