Tis much better to do a little with certainty, and leave the rest for others that come after you, than to explain all things ... " Sir Isaac Newton (1642-1727) This book describes and discusses some new aspects of col or vision in primates which have emerged from a series of experiments conducted over the past 8 years both on single ganglion cells in monkey retina and on the visually evoked cortical potential in man: corresponding psychophysical mechanisms of human perception will be considered as well. An attempt will be made to better understand the basic mechanisms of color vision using a more comprehensive approach which takes into account new mechanisms found in single cells and relates them to those found valid for the entire visual system. The processing of color signals was followed up from the retina to the visual cortex and to the percepq.tal centers, as far as the available techniques permitted.

Available in PDF, EPUB and Kindle. Book excerpt: The retina is the first stage of the visual system, where light is absorbed and encoded in the spikes of neurons. Information from roughly 100 million photoreceptors is compressed to the outputs of roughly 1 million neurons, called retinal ganglion cells, that make up the optic nerve. This is the brain's only source of visual information, yet how the retina uses this limited bandwidth is not well understood. This is particularly true for natural vision in primates, despite its relevance for human health applications, as retinal research is primarily done in non-primate species using targeted, artificial stimuli. Here, large-scale, multi-electrode recordings are used to investigate natural image processing in the primate retina through the complementary lenses of encoding, where computational models are used to predict the responses of RGCs to natural stimuli, and decoding, or reconstruction, where the stimulus is estimated from the RGC responses.

This book was released on 2006-04-07 with total page 1033 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 2019 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The retina provides the sole source of visual information to the brain, yet the signal from the retina is only partially understood. In primates, there are ~20 types of output cells of the retina, called retinal ganglion cells, with each type extracting specific information about the visual scene and projecting to distinct targets in the brain. The five numerically dominant retinal ganglion cell types have been extensively studied, but much less is known about the computations of the remaining ganglion cell types. To understand the visual function of the retina in health and in disease, it is necessary to understand how distinctive signals in the diverse retinal ganglion cell types emerge within retinal circuits, and how they collectively encode visual inputs. This thesis explores the physiological properties of the low-density ganglion cell types. In total, large-scale multi-electrode recordings revealed the responses of 12 retinal ganglion cell types, each with distinctive spatial, temporal, and chromatic properties. Focusing on the ON and OFF smooth monostratified cell types, strikingly irregular receptive field structure composed of spatially segregated hotspots were observed, quite different from the classical view of retinal receptive fields. Direct visual stimulation and computational inference demonstrate strong nonlinearities in the retinal circuit which contribute to receptive field hotspots. Surprisingly, visual stimulation of different hotspots produced subtly different extracellular spike waveforms in the same cell, consistent with a dendritic contribution to hotspot structure. These findings suggest a unique visual computation and spike generation mechanism in the signals carried by smooth monostratified cells to the brain.

Available in PDF, EPUB and Kindle. Book excerpt: A survey is presented of the neurohistological, neuroelectrical, and neurophysiological data relevant to retinal organization. The data are derived from studies of the neural organization of the primate retina. Major current problems include mechanisms of adaptation, spontaneous activity, and efferent influence, details of interconnection patterns, and amacrine function. A theoretical framework for an initial consideration of retinal organization is developed and a model that attempts to account for the properties of graded potentials in the external plexiform layer is presented. The model specifies a hypothetical mechanism as the fundamental source of logarithmic intensity encoding. (Author).

This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The primate fovea is perhaps the most important location for vision in the retina, being specialized for high resolution spatial and chromatic vision, but it has been traditionally difficult to study in ex vivo electrophysiology and especially in vivo. The crucial visual properties conferred by the fovea are mediated by neurons called retinal ganglion cells, which exist in twenty or more distinct types that all tile the retina and are present from the far periphery up to the inner edge of the foveal slope. Microelectrode recordings of foveal retinal ganglion cells have been challenging due to their reduced size and the fragility of tissue survival in excised retina. Some of these difficulties in observing individual cells have been overcome in the in vivo retina by combining high resolution fluorescence adaptive optics ophthalmoscopy with calcium imaging to optically record functional responses in the living primate eye. The work in this thesis advances knowledge of functional properties of retinal ganglion cells at the primate fovea by studying their responses to various stimuli in the living primate (macaca fascicularis) eye. This includes measurements of retinal ganglion cells' chromatic tuning and cone weightings, made possible by silent substitution style uniform chromatic flicker stimuli, and measurements of cells' spatial transfer functions, made possible by monochromatic drifting gratings of various spatial frequencies. In particular, the most common type of retinal ganglion cell, the midget, is studied extensively to generate a broader understanding of the specialization and importance of the primate fovea. This work thus provides a closer look at the in situ spatial, chromatic, and temporal properties of these retinal ganglion cells than ever before possible. A novel stimulation delivery arm as part of a dual adaptive optics ophthalmoscope is also developed as part of this work to improve the resolution and breadth of stimuli used to interrogate the functional properties of retinal ganglion cells. These imaging and stimulation techniques provide a suite of tools for assessing and characterizing the functional properties of retinal ganglion cells in vivo which will inform the next generation of vision restoration strategies such as optogenetics and retinal prostheses."--Pages xi-xii.
