Concepts and Challenges in Retinal Biology


Book Description

In August 2000 a Festschrift was held at the Marine Biological Laboratory, Woods Hole, Massachusetts to celebrate the career of Professor John E. Dowling on the occasion of his 65th birthday. Containing contributions from more than 50 of John's colleagues, representing a Who's Who of the vision research community, this work not only provides a memento of the occasion, but will hopefully serve as a basic reference for future researchers in retinal biology. The volume is divided somewhat arbitrarily into seven areas of retinal research containing chapters that present in some cases a broad overview of a particular topic, and in others an account of current research and studies in progress. These chapters exemplify the richness, diversity, and excitement of contemporary retinal research. They also remind us of how much more needs to be done before we understand fully the interrelationship between retinal neurons, the complex interactions between neurons and glial cells, and the mechanisms that govern retinal development. A final chapter contributed by John Dowling provides an overview of past accomplishments, and offers some future perspectives on retinal research in the 21st century.

The Oxford Handbook of Invertebrate Neurobiology


Book Description

Invertebrates have proven to be extremely useful model systems for gaining insights into the neural and molecular mechanisms of sensory processing, motor control and higher functions such as feeding behavior, learning and memory, navigation, and social behavior. A major factor in their enormous contributions to neuroscience is the relative simplicity of invertebrate nervous systems. In addition, some invertebrates, primarily the molluscs, have large cells, which allow analyses to take place at the level of individually identified neurons. Individual neurons can be surgically removed and assayed for expression of membrane channels, levels of second messengers, protein phosphorylation, and RNA and protein synthesis. Moreover, peptides and nucleotides can be injected into individual neurons. Other invertebrate model systems such as Drosophila and Caenorhabditis elegans offer tremendous advantages for obtaining insights into the neuronal bases of behavior through the application of genetic approaches. The Oxford Handbook of Invertebrate Neurobiology reviews the many neurobiological principles that have emerged from invertebrate analyses, such as motor pattern generation, mechanisms of synaptic transmission, and learning and memory. It also covers general features of the neurobiology of invertebrate circadian rhythms, development, and regeneration and reproduction. Some neurobiological phenomena are species-specific and diverse, especially in the domain of the neuronal control of locomotion and camouflage. Thus, separate chapters are provided on the control of swimming in annelids, crustaea and molluscs, locomotion in hexapods, and camouflage in cephalopods. Unique features of the handbook include chapters that review social behavior and intentionality in invertebrates. A chapter is devoted to summarizing past contributions of invertebrates to the understanding of nervous systems and identifying areas for future studies that will continue to advance that understanding.




Encyclopedia of the Eye


Book Description

As the first comprehensive reference for the eye, its support structures, diseases, and treatments, Encyclopedia of the Eye is an important resource for all visual scientists, ophthalmologists, and optometrists, as well as researchers in immunology, infectious disease, cell biology, neurobiology and related disciplines. This four-volume reference is unique in its coverage of information on all tissues important for vision, including the retina, cornea and lens. It also covers the physiological and pathophysiologic processes that affect all eye tissues. This Encyclopedia is invaluable for graduate students and postdoctoral fellows who are seeking an introduction to an area of eye research. Each chapter explains the basic concepts and provides references to relevant chapters within the Encyclopedia and more detailed articles across the wider research literature. The Encyclopedia is also particularly useful for visual scientists and practitioners who are researching a new area, seeking deeper understanding of important research articles in fields adjacent to their own, or reviewing a grant outside their immediate area of expertise. Written by experts at a level that permits students to grasp key elements of a specific subject Provides an entryway into the major features of current eye research No other source puts this much information, so well-indexed and with so many helpful full color figures and graphics, in the hands of the ophthalmic scientist




Principles and Practice of Clinical Electrophysiology of Vision, second edition


Book Description

The long-awaited second edition of an authoritative reference on electrophysiologic vision testing, including detailed information on techniques and problems, basic physiology and anatomy, theoretical concepts, and clinical findings; with extensive new material. This authoritative text is the only comprehensive reference available on electrophysiologic vision testing, offering both practical information on techniques and problems as well as basic physiology and anatomy, theoretical concepts, and clinical correlations. The second edition, of the widely used text, offers extensive new material and updated information: 65 of the 84 chapters are completely new, with the changes reflecting recent advances in the field. The book will continue to be an essential resource for practitioners and scholars from a range of disciplines within vision science. The contributions not only cover new information—important material that is likely to become more important in the next decade—but also offer a long-range perspective on the field and its remarkable development in the last century. After discussing the history and background of clinical electrophysiology, the book introduces the anatomy of the retina and principles of cell biology in the visual pathways at the molecular, physiological, and biochemical levels. It relates these new findings to the techniques and interpretations of clinical tests, including the electro-oculogram (EOG), electroretinogram (ERG), and visual evoked potentials (VEP), which are discussed in detail, as are equipment, data acquisition and analysis, principles and protocols for clinical testing, diseases and dysfunction, and animal testing. Notable additions for this edition include chapters on the origin of electroretinogram waveforms, multifocal techniques, testing in standard laboratory animals, recent advances in analysis of abnormalities in disease, and the applications of these techniques to the study of genetic abnormalities.

Book Description

Müller cells make up just 0.005% of the cells in our central nervous system. They do not belong to the more esteemed family of neuronal cells but to the glia, a family of cells that until recently were seen as mere filling material between the neurons. Now, however, all that has changed. Sharing the insights of more than a quarter century of research into Müller cells, Drs. Andreas Reichenbach and Andreas Bringmann of Leipzig University make a compelling case for the central role Müller cells play. Everyone agrees that the eye is a very special and versatile sense organ, yet it has turned out in recent years that Müller cells are peculiar and multipotent glial cells. In the retina of most vertebrates and even of many mammals, Müller cells are the only type of (macro- ) glial cells; thus, they are responsible for a wealth of neuron-supportive functions that, in the brain, rely upon a division of labour among astrocytes, oligodendrocytes, and ependymal cells. Even beyond such a role in the central nervous system as "model glia", Müller cells are adapted to several exciting roles in support of vision. They deliver the light stimuli to the photoreceptor cells in the inverted vertebrate retina, aid the processing of visual information, and are responsible for the homeostatic maintenance of the retinal extracellular milieu. In Müller Cells in the Healthy and Diseased Retina, aimed not just at neurobiologists but at anyone concerned with retinal degeneration, every angle of Müller cells is covered, from an introduction to their basic properties, through their roles as 'light cables' and 'shock absorbers', to the part they play in diseases and disorders of the eye. Once these have all been covered in detail, the authors move on to discuss the future direction of research into these small but potent cellular phenomena. About the Authors Dr. Andreas Reichenbach was born in 1950 in Leipzig, Germany. He studied medicine and specialized as a physiologist, working on the mammalian retina. Since 1984, he has focused his efforts - and those of a growing number of fellows in his team - on Müller cell research. He has held a professorship at Leipzig University since 1994. After studying biology, Dr. Andreas Bringmann (* 1960) worked in the field of systemic neurophysiology until he was inspired in 1996 by Andreas Reichenbach to research the most interesting cell, the Müller cell. He is now in the Department of Ophthalmology of the University of Leipzig where he is the head of the Basic Research Laboratory
