Book excerpt: One hundred years ago Ernst Mach published the first of his several quantitative studies on the interdependence of neighboring elements in the retina. However, Mach's application of mathematical modes of thought to the study of the nervous system was so far ahead of the times that his papers attracted little attention when they first appeared. Within recent years considerable interest has developed in the mathematical analysis of the properties of complex neural networks. The main reason for this seemingly belated development of interest is that only within the last quarter-century or so have the techniques of electrophysiology finally become sufficiently advanced to provide a sound empirical foundation for such studies. The interplay of the fundamental neural processes of excitation and inhibition, about which Mach could only speculate, can now be observed directly and with relative ease in practically all parts of the nervous system.

This book was released on 2013-03-08 with total page 439 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the mid-sixties, John Robson and Christina Enroth-Cugell, without realizing what they were doing, set off a virtual revolution in the study of the visual system. They were trying to apply the methods of linear systems analysis (which were already being used to describe the optics of the eye and the psychophysical performance of the human visual system) to the properties of retinal ganglion cells in the cat. Their idea was to stimulate the retina with patterns of stripes and to look at the way that the signals from the center and the antagonistic surround of the respective field of each ganglion cell (first described by Stephen Kuffier) interact to generate the cell's responses. Many of the ganglion cells behaved themselves very nicely and John and Christina got into the habit (they now say) of calling them I (interesting) cells. However. to their annoyance, the majority of neurons they recorded had nasty, nonlinear properties that couldn't be predicted on the basis of simple summ4tion of light within the center and the surround. These uncoop erative ganglion cells, which Enroth-Cugell and Robson at first called D (dull) cells, produced transient bursts of impulses every time the distribution of light falling on the receptive field was changed, even if the total light flux was unaltered.

Download or read book Retinal Ganglion Cells written by Ben Mead and published by Springer Nature. This book was released on 2023-08-09 with total page 201 pages. Available in PDF, EPUB and Kindle. Book excerpt: This collection provides methods and techniques employed when culturing, manipulating, quantifying, and functionally assessing retinal ganglion cells (RGCs), vital for better understanding various ocular diseases and for developing novel therapies. The book features exhaustive and detailed protocols for the study of RGCs at both the in vitro and in vivo level, including the culture of rodent and human cells, and immunohistochemical, morphological, and functional assessments of various in vivo models of RGC death. Written for the highly successful Methods in Molecular Biology series, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step and readily reproducible laboratory protocols, and tips on troubleshooting and avoiding known pitfalls. Authoritative and practical, Retinal Ganglion Cells: Methods and Protocols serves as an ideal guide to these important cellular features of the central nervous system and the many traumatic and degenerative blinding diseases that affect them.

This book was released on 2013-04-17 with total page 674 pages. Available in PDF, EPUB and Kindle. Book excerpt: John Lythgoe was one of the pioneers of the 'Ecology of Vision', a subject that he ably delineated in his classic and inspirational book published some 20 years ago [1]. At heart, the original book aimed generally to identify inter-relationships between vision, animal behaviour and the environment. John Lythgoe excelled at identifying the interesting 'questions' in the ecology of an animal that fitted the 'answers' presented by an analysis of the visual system. Over the last twenty years, however, since Lythgoe's landmark publication, much progress has been made and the field has broadened considerably. In particular, our understanding of the 'adaptive mechanisms' underlying the ecology of vision has reached considerable depths, extending to the molecular dimension, partly as a result of development and application of new techniques. This complements the advances made in parallel in clinically oriented vision research [2]. The current book endeavours to review the progress made in the ecology of vision field by bringing together many of the major researchers presently active in the expanded subject area. The contents deal with theoretical and physical considerations of light and photoreception, present examples of visual system structure and function, and delve into aspects of visual behaviour and communi cation. Throughout the book, we have tried to emphasise one of the major themes to emerge within the ecology of vision: the high degree of adaptability that visual mechanisms are capable of undergoing in response to diverse, and dynamic, environments and behaviours.
Download or read book Eye Retina and Visual System of the Mouse written by Leo M. Chalupa and published by MIT Press. This book was released on 2008 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This comprehensive guide to current research captures the first wave of studies in the field, with fifty-nine chapters by leading scholars that demonstrate the usefulness of mouse models as a bridge between experimental and clinical research. The opening chapters introduce the mouse as a species and research model, discussing such topics as the mouse's evolutionary history and the mammalian visual system. Subsequent sections explore more specialized subjects, considering optics, psychophysics, and the visual behaviors of mice; the organization of the adult mouse eye and central visual system; the development of the mouse eye (including comparisons to human development); the development and plasticity of retinal projections and visuotopic maps; mouse models for human eye disease (including glaucoma and cataracts); and the application of advanced genomic technologies (including gene therapy and genetic knockouts) to the mouse visual system. Readers of this reference will see th.

Available in PDF, EPUB and Kindle. Book excerpt: The loss of retinal ganglion cells (RGCs) causes irreversible vision loss in glaucoma and optic neuropathies. Some vertebrate species, such as zebrafish, possess a robust ability to regenerate parts of their body, including the retina through a process of endogenous regeneration. However, this ability is limited in mammals including humans. To understand endogenous regeneration and work towards restoring RGCs, we need to gain a better understanding of the developmental mechanisms leading to RGC formation. Our approach relies on the generation of RGC reporters that express fluorescent proteins coupled to the endogenous BRN3A and BRN3B genes. By ectopically overexpressing four transcription factors (Neurogenin-2, Atonal homolog 7, Islet-1, and Brn3b) involved in RGC specification and differentiation, we seek to directly convert the human pluripotent stem cell reporters into RGCs. If the differentiated neurons become bonafide BRN3A/BRN3B expressing RGCs, this would represent an important first step in developing and improving novel therapeutic strategies for retinal diseases.
