Download or read book Comparative Color Vision written by Gerald Jacobs and published by Elsevier. This book was released on 2013-06-11 with total page 218 pages. Available in PDF, EPUB and Kindle. Book excerpt: Comparative Color Vision provides information about the means by which color vision has been studied in nonhuman animals and about the outcomes of these studies for a variety of representative species. Individuals who become interested in color vision in animals come from a variety of different educational backgrounds—from the traditional biological and behavioral sciences as well as from more applied fields. Accordingly, this book includes sufficient tutorial information about color vision so that a relative newcomer would be able to make sense out of this area without having to search out still more background material. To provide this, basic information about the psychophysics of color vision and about the methods used to study color vision in animals is presented; along with coverage of the broad range of biological mechanisms responsible for color vision. Subsequent chapters present systematic reviews of studies of color vision in a wide selection of vertebrate species. The final chapter is devoted to a discussion of two fascinating issues raised by studies of animal color vision: the evolutionary origins and the functional utility of color vision.
Download or read book The Visually Responsive Neuron written by T. Philip Hicks and published by Elsevier. This book was released on 1993 with total page 507 pages. Available in PDF, EPUB and Kindle. Book excerpt: This timely new volume presents broad-based and wide-ranging contributions on all aspects of vision. The material is grouped for presentation in a logical fashion in five main themes: peripheral processing; sensory integration in superior colliculus; organization of visual projections; development and plasticity; and neuronal encoding and visually guided behavior. The material spans from molecules to cognition, including overt behavior, and synaptic and membrane levels of analysis. The species studied also range over diverse phyla, while contributors too form a diverse group representing Europe, North America, and Asia. The Visually Responsive Neuron is an exciting and informative addition to the well known Progress in Brain Research series.

This book was released on 2012-12-06 with total page 788 pages. Available in PDF, EPUB and Kindle. Book excerpt: The present volume covers the physiology of the visual system beyond the optic nerve. It is a continuation of the two preceding parts on the photochemistry and the physiology of the eye, and forms a bridge from them to the fourth part on visual psychophysics. These fields have all developed as independent speciali ties and need integrating with each other. The processing of visual information in the brain cannot be understood without some knowledge of the preceding mechanisms in the photoreceptor organs. There are two fundamental reasons, ontogenetic and functional, why this is so: 1) the retina of the vertebrate eye has developed from a specialized part of the brain; 2) in processing their data the eyes follow physiological principles similar to the visual brain centres. Peripheral and central functions should also be discussed in context with their final synthesis in subjective experience, i. e. visual perception. Microphysiology and ultramicroscopy have brought new insights into the neuronal basis of vision. These investigations began in the periphery: HARTLINE'S pioneering experiments on single visual elements of Limulus in 1932 started a successful period of neuronal recordings which ascended from the retina to the highest centres in the visual brain. In the last two decades modern electron microscopic techniques and photochemical investigations of single photoreceptors further contributed to vision research.

This book was released on 2012-12-06 with total page 349 pages. Available in PDF, EPUB and Kindle. Book excerpt: AUGUST F. DEUTMAN, M.D. From October 16-18, 197 5 many distinguished ophthalmologists visited Nijmegen to inaugurate the new Eye Institute of the University of Nijmegen with a symposium on New Developments in Ophthalmology. The meeting was held under the auspices of the Netherlandish Ophthalmological Society (NOG) and had a high attendance of over 300 ophthalmologists from The Netherlands and from abroad. Many new and some controversial surgical techniques regarding corneal transplantation, phako-emulsification, intra-ocular lensimplantation, local excision of melanomas of the choroid and ciliary body, pars plana vitrec tomy, laser treatment in disciform macular degeneration and treatment of giant retinal tears were discussed. Since new surgical techniques have to be based on profound knowledge of the anatomy and physiology of the eye, many new basic and important data regarding the cornea, the vitreous body, the retinal vessels, the choroid and the orbit were presented by some of the foremost authorities. Technical advances in corneal transplantation were discussed, while the modern treatment of corneal ulcers and bacterial infections of the eye was presented. New findings such as computerized tomography, facilitate the diagnosis of underlying disease in exophthalmus enormously. The treatment of retinal detachment has improved considerably over the last ten years and we feel that in particular the safe non-drainage methods deserve attention. Cryo coagulation and photocoagulation have certain advances over diathermy and the radial placement of indenting suprascleral material may have consider able advantages over the limbus-parallel placement in horseshoe tears.
Download or read book Behavior of Nonhuman Primates written by Allan M. Schrier and published by Academic Press. This book was released on 2014-06-28 with total page 225 pages. Available in PDF, EPUB and Kindle. Book excerpt: Behavior of Nonhuman Primates: Modern Research Trends, Volume 3 provides information pertinent to research on behavior of nonhuman primates. This book presents the knowledge of the social development of rhesus infants and compares with data on other species. Organized into four chapters, this volume begins with an overview of the interspecies differences in the social influences affecting young primates. This text then examines the nature of the interactions between the infant and its various social companions, wherein each type of social companion may interact with the infant in a number of ways. Other chapters consider the nature of the social organization, which may be presumed to have been shaped by the ecological pressures of the natural habitat. This book discusses as well the color vision and visual acuity in different animals. The final chapter deals with the aspects of primate hearing. This book is a valuable resource for students and research workers.
Download or read book Color Vision Sensitivity in Normally Dichromatic Species and Humans written by Richard E. Van Arsdel and published by . This book was released on 2002-09-01 with total page 97 pages. Available in PDF, EPUB and Kindle. Book excerpt: Spectral sensitivity functions for large, long-duration spectral stimuli presented on a photopic white background indicate that wavelength opponent mechanisms mediate detection of such stimuli in both normal and dichromatic humans. Normal humans detect the color of spectral flashes at detection threshold intensities, supporting the premise that wavelength opponent processes signal color. However, dichromatic humans do not see some colors at threshold; rather, they require stimuli up to about 0.4 log units above detection intensity. This suggests that dichiomatic humans may have a defect in postre- ceptoral color processing. To test this, we determined color discrimination thresholds in normally occurring dichromats, including the chipmunk, the 13-lined ground squirrel, and the tree shrew.
