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 Spike Timing written by Patricia M. DiLorenzo and published by CRC Press. This book was released on 2013-05-02 with total page 425 pages. Available in PDF, EPUB and Kindle. Book excerpt: Neuronal communication forms the basis for all behavior, from the smallest movement to our grandest thought processes. Among the many mechanisms that support these functions, spike timing is among the most powerful and—until recently—perhaps the least studied. In the last two decades, however, the study of spike timing has exploded. The heightened interest is due to several factors. These include the development of physiological tools for measuring the activity of neural ensembles and analytical tools for assessing and characterizing spike timing. These advances are coupled with a growing appreciation of spike timing’s theoretical importance for the design principles of the brain. Spike Timing: Mechanisms and Function examines the function of spike timing in sensory, motor, and integrative processes, providing readers with a broad perspective on how spike timing is produced and used by the nervous system. It brings together the work and ideas of leaders in the field to address current thinking as well as future possibilities. The first section of the book describes the foundation for quantitative analysis and theory. It examines the information contained in spike timing, how it can be quantified, and how neural systems can extract it. The second section explores how input-output relationships are reflected in spike timing across a range of sensory systems. Drawing together multiple perspectives, including theoretical and computational studies as well as experimental studies in a range of model systems, the book provides a firm background for investigators to consider spike timing as it applies to their own work. It also offers a glimpse of future advances related to mechanisms of spike timing and its role in neural function, such as the development of novel computational technologies.
Download or read book Perceiving in Depth Volume 1 Basic Mechanisms written by Ian P. Howard and published by Oxford University Press. This book was released on 2012-01-27 with total page 671 pages. Available in PDF, EPUB and Kindle. Book excerpt: The three-volume work Perceiving in Depth is a sequel to Binocular Vision and Stereopsis and to Seeing in Depth, both by Ian P. Howard and Brian J. Rogers. This work is much broader in scope than the previous books and includes mechanisms of depth perception by all senses, including aural, electrosensory organs, and the somatosensory system. Volume 1 reviews sensory coding, psychophysical and analytic procedures, and basic visual mechanisms. Volume 2 reviews stereoscopic vision. Volume 3 reviews all mechanisms of depth perception other than stereoscopic vision. The three volumes are extensively illustrated and referenced and provide the most detailed review of all aspects of perceiving the three-dimensional world. Volume 1 starts with a review of the history of visual science from the ancient Greeks to the early 20th century with special attention devoted to the discovery of the principles of perspective and stereoscopic vision. The first chapter also contains an account of early visual display systems, such as panoramas and peepshows, and the development of stereoscopes and stereophotography. A chapter on the psychophysical and analytic procedures used in investigations of depth perception is followed by a chapter on sensory coding and the geometry of visual space. An account of the structure and physiology of the primate visual system proceeds from the eye through the LGN to the visual cortex and higher visual centers. This is followed by a review of the evolution of visual systems and of the development of the mammalian visual system in the embryonic and post-natal periods, with an emphasis on experience-dependent neural plasticity. An account of the development of perceptual functions, especially depth perception, is followed by a review of the effects of early visual deprivation during the critical period of neural plasticity on amblyopia and other defects in depth perception. Volume 1 ends with accounts of the accommodation mechanism of the human eye and vergence eye movements.

This book was released on 2011 with total page 206 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: The function of the retina is to encode relevant features of the visual world in the form of neural spike trains. These are transmitted to higher visual centers in the brain by retinal ganglion cells (RGCs), which form the neural output of the retina. Little is known about the receptive field properties of these cells in the rat. In vivo recording techniques were used to record from RGC axons while visual stimuli were displayed on a cathode ray tube. Rats have a wide visual field and large receptive fields. In order to capture the majority of the visual field, the monitor was placed in close proximity to the eye of the animal. Visual stimulus patterns such as luminance gratings appear distorted at a close viewing distance. We therefore simulated a spherical screen with the eye at its center. Cells shared many properties with those of other species but also exhibited some notable differences. Some cells exhibited the characteristic linear and nonlinear spatial summation of cat X and Y cells and were therefore labeled as X and Y-like. More rarely encountered cell types included the suppressed by contrast and ON-OFF surround cells. In contrast to their counterparts in the cat, X and Y-like cells in the rat had similar receptive field sizes. In the temporal domain, X-like cells exhibited sustained response dynamics to square wave modulated spots. Y-like cells, on the other hand, displayed both sustained and transient response dynamics. Both cell types responded to full field stimuli by reducing their gain at low temporal frequencies and exhibiting a resonance at higher frequencies. These results question the commonly assigned roles of X-like cells in high acuity vision and Y-like cells in motion detection. Anatomical data on their morphological properties and projection pattern will provide additional insight into their possible functional roles. Photodynamic staining provides a means of targeting cells for electrophysiological recordings that display specific morphological and projection patterns. We found enhanced photodynamic staining in media supplemented with oxygen or hydrogen peroxide. This information will aid future experiments correlating the anatomical and electrophysiological properties of RGC types.
Download or read book Vision From Neurons to Cognition written by C. Casanova and published by Gulf Professional Publishing. This book was released on 2001-10-25 with total page 514 pages. Available in PDF, EPUB and Kindle. Book excerpt: Internationally renowned researchers discuss how the various parts of the brain process and integrate visual signals, providing up to date original findings, reviews, and theoretical proposals on visual processing. This book addresses the basic mechanisms of visual perception as well as issues such as neuronal plasticity, functional reorganization and recovery, residual vision, and sensory substitution. Knowledge of the basic mechanisms by which our brain can analyze, reconstruct, and interpret images in the external world is of fundamental importance for our capacity to understand the nature and causes of visual deficits, such as those resulting from ischemia, abnormal development, neuro-degenerative disorders, and normal aging. It is also essential to our goal of developing better therapeutic strategies, such as early diagnosis, visual training, behavioral rehabilitation of visual functions, and visual implants.
