Book Description
In recent years, the suprasylvian gyrus of the cat has attracted the attention of many neurophysiologists and experimental psychologists and the variety of their interests is reflected in the number of morphological and functional sub divisions which have been made of it. Some of these subdivisions are shown in Fig. 1. Workcrs concerned with t. hc visual system havc made studies of the third visual area (awa to) on the medial aspect. of thc gyrus, and of the latcral supra sylvian area on the lateral aspeet, both of which contain representations of the retina (Clare and Bishop, 1954; Hubel and Wiesel, 1965, 1969; Wright, 1969). However, the full extent of these areas and particularly of the latter, is still not known. Other workers have investigated the extent of the gyrus activated by somatic sensory (Darian. Smith, Isbister, Mok and Yokota, 1966) or auditory (Woolsey, 1961) stimuli. A third field of incrcasing interest is the study of the "polysensory areas" of the cortex, two of which are situated in the middle supra sylvian gyrus. In these areas, in animals anaesthetized with chloralose, conver gence upon single neurons of auditory, somatic and visual impulses has been demonstrated (see ego Thompson, Johnson and Hoopes, 1963; Dubner and Rut ledge, 1964, 1965; Dubner, 1966; Bignall, 1967) and it has been proposed that these areas play an important part in the central processing of sensory information (Buser and Bignall, 1967; Thompson, 1967).

Book Description
Written by experts on the forefront of investigations of brain function, vision, and perception, the material presented is of an unparalleled scientific quality, and shows that analyses of enormous breadth and sophistication are required to probe the structure and function of brain regions. The articles are highly persuasive in showing what can be achieved by carrying out careful and imaginative experiments. The Cat Primary Visual Cortex should emerge as essential reading for all those interested in cerebral cortical processing of visual signals or researching or working in any field of vision. Comprehensive account of cat primary visual cortex Generous use of illustrations including color Covers research from structure to connections to functions Chapters by leaders in the field Topics presneted on multiple, compatible levels

Book Description
Much can be learned about the functional organization of the visual system by examining its anatomy. In traditionally-studied cat and primate species, certain morphological types of retinal ganglion cells project to specific thalamic and then cortical layers, separated by eye in each region. In addition, physiology shows that information is segregated by functional cell type; each layer is a complete or near-complete map of some aspect of the world such as form and motion. This results in a system that can easily distribute specialized information without disrupting the larger visuo-spatial map. While the layers of the macaque retino-recipient thalamus are easily discernible due to the correlation between cytoarchitecture and function, the rat geniculate appears to have no such patterning. As the rat is a favorable research model, it is important to understand how its brain is set up to tackle the same visual problems as that of higher mammals. The purpose of this project was to describe substructure within the rat dorsal lateral geniculate nucleus of the thalamus, with the goal of learning more about how the anatomical organization might give insight into function. To visualize the anatomy, I intra-occularly injected retrograde tracer to map retinal termini throughout the nucleus. Based on three-dimensional reconstructions of termination zones from each eye, I identified multiple ipsilaterally-recipient zones within the largely contralateral thalamic nucleus. These ipsilateral subregions are more reminiscent of the layering in the primate thalamus than previously described in the rat. Furthermore, the nucleus appears to be well segregated by eye, suggesting that, like in these other species, the rat thalamus passes on information without binocular mixing. My findings also support the hypothesis that, unlike in the primate, rat cell bodies throughout the layers appear to be cytoarchitecturally homogeneous. While we can glean insight into the function of macaque thalamic layers by looking at cell-body statistics such as size and density, no such patterns can be seen in the rat. Among other possibilities, this could mean that rat projection neurons have similar morphologies, or that functional cell types are intermingled and not spatially organized as they are in other species.

Neuroanatomy of the Mouse

ISBN: 3030198987

Languages : en
Pages : 353
Book Description
This textbook describes the basic neuroanatomy of the laboratory mouse. The reader will be guided through the anatomy of the mouse nervous system with the help of abundant microphotographs and schemata. Learning objectives and summaries of key facts at the beginning of each chapter provide the reader with an overview on the most important information. As transgenic mice are one of the most widely used paradigms when it comes to modeling human diseases, a basic understanding of the neuroanatomy of the mouse is of considerable value for all students and researchers in the neurosciences and pharmacy, but also in human and veterinary medicine. Accordingly, the authors have included, whenever possible, comparisons of the murine and the human nervous system. The book is intended as a guide for all those who are about to embark on the structural, histochemical and functional phenotyping of the mouse’s central nervous system. It can serve as a practical handbook for students and early researchers, and as a reference book for neuroscience lectures and laboratories.
