Book Description
"Stimulation of the Superior Colliculus and Visual Cortex, which are involved in d1fferent aspects of visual perception, revealed convergence of efferents from these two regions at the neuronal level in the motor cortex of chloralose anesthetized cats. Cells in this area displayed well-defined visual receptive. fields to punctiform visual stimulation, along with movement sensitivity and some directional specificity. Investigation of the topographica1 distribution of visual input to the motor cortex revealed that cells with cutaneous input from the proximal areas of the extremities and the trunk are also possess visual receptive fields (72%), whereas units with cutaneous input from the distal fore limb area receive much less (15%) visual information. These findings support the growing body of evidence pointing to a differential organizat1on of the neural systems controlling the distal musculature and those controlling the musculature of the body axis." --

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
The present day is witnessing an explosion of our understanding of how the brain works at all levels, in which complexity is piled on complexity, and mechanisms of astonishing elegance are being continually discovered. This process is most developed in the major areas of the brain, such as the cortex, thalamus, and striatum. The Claustrum instead focuses on a small, remote, and, until recently, relatively unknown area of the brain. In recent years, researchers have come to believe that the claustrum is concerned with consciousness, a bold hypothesis supported by the claustrum’s two-way connections with nearly every other region of the brain and its seeming involvement with multisensory integrations—the hallmark of consciousness. The claustrum, previously in a humble position at the back of the stage, might in fact be the conductor of the brain’s orchestra. The Claustrum brings together leading experts on the claustrum from the varied disciplines of neuroscience, providing a state-of-the-art presentation of what is currently known about the claustrum, promising lines of current research (including epigenetics), and projections of new lines of investigation on the horizon. Develops a unifying hypothesis about the claustrum’s role in consciousness, as well as the integration of sensory information and other higher brain functions Discusses the involvement of the claustrum with autism, schizophrenia, epilepsy, Alzheimer’s disease, and Parkinson’s disease Coverage of all aspects of the claustrum, from its evolution and development to promising new lines of research, including epigenetics, provides a platform and point of reference for future investigative efforts

Book Description
This volume is a compilation of current research on somatosensation and its underlying mechanisms written by international experts from a broad range of disciplines. It is divided into six sections:· structural basis of information processing and neocortical neurotransmitters · psychophysics of somatosensation · cortical representation of somatosensation · sensory-motor interface · neuronal population behavior · cortical neurocomputation and modelling. It highlights not only important new findings but also novel methods and technologies applied to major unresolved issues in the field of neuroscience. The number of methods for investigating the neural mechanisms of soma-tosensory perception has grown substantially in the last decade. The book encompasses levels of inquiry from ionic channels, single unit recordings of neural activity, and functional brain imaging of the coordinated activity of large neuronal ensembles to human psychophysics of controlled somatic stimulation. This work is of great value for researchers and students interested in the dynamic neuronal mechanisms involved in the complex processes of sensory perception and provides a picture of our present understanding of the neural representation of the external world relayed through the somatosensory system.
