This book was released on 2009 with total page 242 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: The majority of ganglion cells in the salamander retina receive excitatory synaptic inputs from the ON and the OFF pathway, but little is known about the functional role of these cells. Previous studies suggest that they might be involved in the processing of complex visual features, however attempts to categorize cells into distinct groups of complex feature detectors have failed. This work focuses on the functional analysis of the excitatory synaptic inputs to ON-OFF ganglion cells recorded in the retinal slice preparation. Responses to stimulation with contrast steps and random luminance sequences were analyzed regarding their temporal dynamics and contrast processing. We found that cells lie along a continuum of varying relative contributions from the ON and the OFF pathway and show asymmetries regarding contrast processing and temporal dynamics in the OFF and ON inputs. We further investigated the use of a covariance based analysis to separate the ON and OFF components in current responses to white noise stimulation. Computer simulations were used to evaluate the performance of the analysis under different conditions. The analysis performs well in predicting the responses of simulated ON-OFF cells, however, caution needs to be applied in the physiological interpretation of the components of the estimated model, in particular if the assumption of contrast rectification is violated. Finally, we show how ON-OFF cells can account for complex temporal response patterns. We show how a simple ON-OFF model can produce spiking responses that seem to code for violations in periodic temporal patterns. The model is consistent with the results of patch clamp recordings of the excitatory current responses to periodic flash sequences. The model further demonstrates how relatively small changes in the static nonlinearities within the ON and the OFF pathway can produce a variety of seemingly complex response patterns in the spike output. In conclusion, ganglion cells in the salamander retina form a diverse group of cells varying along an ON-OFF continuum. The temporal asynchrony between the two pathways as well as variations in contrast rectification can account for complex response patterns observed in those cells and might play an important role in visual coding.

Available in PDF, EPUB and Kindle. Book excerpt: The first two editions of this title had a tremendous impact in neuroscience. Between the Second edition in 1989 and today, there has been an explosion of information in the field, including advances in molecular techniques, such as genomics and proteomics, which have become increasing important in neuroscience. A renaissance in fluorescence has occurred, driven by the development of new probes, new microscopes, live imagers, and computer processing. The introduction of new markers has enormously stimulated the field, moving it from tissue culture to neurophysiology to functional MRI techniques.

Download or read book Retinal Development written by Evelyne Sernagor and published by Cambridge University Press. This book was released on 2012-11-29 with total page 369 pages. Available in PDF, EPUB and Kindle. Book excerpt: This advanced text, first published in 2006, takes a developmental approach to the presentation of our understanding of how vertebrates construct a retina. Written by experts in the field, each of the seventeen chapters covers a specific step in the process, focusing on the underlying molecular, cellular, and physiological mechanisms. There is also a special section on emerging technologies, including genomics, zebrafish genetics, and stem cell biology that are starting to yield important insights into retinal development. Primarily aimed at professionals, both biologists and clinicians working with the retina, this book provides a concise view of vertebrate retinal development. Since the retina is 'an approachable part of the brain', this book will also be attractive to all neuroscientists interested in development, as processes required to build this exquisitely organized system are ultimately relevant to all other parts of the central nervous system.

Book excerpt: Development and Organization of the Retina offers an invaluable survey of contemporary research issues and methods dealing with the retina and retinal projections. The book's 19 chapters report on investigations into two areas: research into the organization of the mature retina and work on developmental issues. A sampling of chapter topics includes -- embryonic patterning of cone subtypes in the mammalian retina -- synaptic transmission between retinal neurons -- scaling the retina, macro and micro -- retinal ganglion cell axonal transport, and more.
Download or read book The New Visual Neurosciences written by John S. Werner and published by MIT Press. This book was released on 2013-10-25 with total page 1693 pages. Available in PDF, EPUB and Kindle. Book excerpt: A comprehensive review of contemporary research in the vision sciences, reflecting the rapid advances of recent years. Visual science is the model system for neuroscience, its findings relevant to all other areas. This essential reference to contemporary visual neuroscience covers the extraordinary range of the field today, from molecules and cell assemblies to systems and therapies. It provides a state-of-the art companion to the earlier book The Visual Neurosciences (MIT Press, 2003). This volume covers the dramatic advances made in the last decade, offering new topics, new authors, and new chapters. The New Visual Neurosciences assembles groundbreaking research, written by international authorities. Many of the 112 chapters treat seminal topics not included in the earlier book. These new topics include retinal feature detection; cortical connectomics; new approaches to mid-level vision and spatiotemporal perception; the latest understanding of how multimodal integration contributes to visual perception; new theoretical work on the role of neural oscillations in information processing; and new molecular and genetic techniques for understanding visual system development. An entirely new section covers invertebrate vision, reflecting the importance of this research in understanding fundamental principles of visual processing. Another new section treats translational visual neuroscience, covering recent progress in novel treatment modalities for optic nerve disorders, macular degeneration, and retinal cell replacement. The New Visual Neurosciences is an indispensable reference for students, teachers, researchers, clinicians, and anyone interested in contemporary neuroscience.

Download or read book Vertebrate Photoreceptors written by Takahisa Furukawa and published by Springer. This book was released on 2016-08-23 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
