This book was released on 2006 with total page 276 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this thesis, we examined the monkey cortical regions involved in processing of color, visual motion information, and the recognition of actions done by others. The aim was to gain better insight in the functional organization of the monkey visual cortex using in-house developed functional imaging techniques. Two different functional imaging techniques were used in these studies, the double-label deoxyglucose technique (DG) and functional magnetic resonance imaging (fMRI) in the awake monkey (Chapter 2). Both techniques allow to obtain an overview of stimulus-related neural activity throughout the whole brain, integrated over a limited amount of time. The results of the color experiments (Chapter 3) clearly showed that color related information is processed within a group of areas belonging to the ventral stream, which is involved in the perception of objects. Color-related metabolic activity was observed in visual areas V1, V2, V3, V4 and inferotemporal cortex (area TEO and TE). These findings set to rest the longstanding controversial claims that color would be processed almost selectively in one extrastriate visual area (V4) (Zeki SM, Brain Res 1973 53: 422-427). These results also show the usefulness of whole brain functional mapping techniques, as a complimentary approach to single cell measurements. In Chapter 4, we investigated which regions in the superior temporal sulcus (STS) of the monkey are involved in the analysis of motion. While the caudal part of the STS has been studied extensively, including area MT/V5 and MST, little is known about motion sensitivity in more anterior-ventral STS regions. Using fMRI, we were able to localize and delineate six different motion sensitive regions in the STS. One of these regions, that we termed 1st (lower superior temporal), had not been described so far. We were able to further characterize the six motion sensitive regions, using a wide variety of motion-sensitivity tests. The results of the latter tests suggested that motion related information might be processed along a second pathway within the STS, in addition to the MT-MST path (which is involved in the perception of heading). This second pathway, which includes the more rostral motion sensitive STS regions (FST, 1st and STPm) is possibly involved in the visual processing of biological movements (movements of animate objects) and actions. Finally, we investigated how and where in the monkey brain visual information about actions done is processed (Chapter 5 and 6). We found (Chapter 5) that, in agreement with earlier single unit results, the observation of grasping movements activates several regions in the premotor cortex of the monkey. Remarkable is that these premotor regions predominantly have a motor function, coding different types of higher order motor acts (for instance grasping of an object). These results are in agreement with earlier suggestions that we are able to understand actions done by others, because observation of a particular motor act activates our own motor representation of the same act. Furthermore, these studies suggested that within the frontal cortex of the monkey, there is a distinction between context-dependent (a person grasping) and more abstract (a hand grasping) action representations. In Chapter 6 we studied two other regions which are involved in the processing of visual information of actions done by others, the superior temporal sulcus (STS) and the parietal cortex. In the parietal cortex, we found a similar distinction between context-dependent and more abstract action representations as observed in prefrontal cortex. These results suggest that the parietal cortex is not only involved in the visual control of action planning, but also in the visual processing of actions performed by others. Based upon anatomical connections between the STS, parietal and frontal regions and motion-, form- and action-related functional properties of the former regions, we tentatively suggest how information about actions done by others might be sent from the STS to the frontal cortex along three different pathways. The latter working hypothesis will be tested in the future by additional fMRI control experiments and by combining fMRI, inactivation and microstimulation experiments while monkeys perform grasping tasks and/or view actions performed by others.

Book excerpt: A key property of neural processing in higher mammals is the ability to focus resources by selectively directing attention to relevant perceptions, thoughts or actions. Research into attention has grown rapidly over the past two decades, as new techniques have become available to study higher brain function in humans, non-human primates, and other mammals. Neurobiology of Attention is the first encyclopedic volume to summarize the latest developments in attention research.An authoritative collection of over 100 chapters organized into thematic sections provides both broad coverage and access to focused, up-to-date research findings. This book presents a state-of-the-art multidisciplinary perspective on psychological, physiological and computational approaches to understanding the neurobiology of attention. Ideal for students, as a reference handbook or for rapid browsing, the book has a wide appeal to anybody interested in attention research. * Contains numerous quick-reference articles covering the breadth of investigation into the subject of attention* Provides extensive introductory commentary to orient and guide the reader* Includes the most recent research results in this field of study
Download or read book Sensory Integration written by R. Masterton and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 587 pages. Available in PDF, EPUB and Kindle. Book excerpt: The principal goal of the Handbook of Behavioral Neurobiology is a systematic, critical, and timely exposition of those aspects of neuroscience that have direct and immediate bearing on overt behavior. In this first volume, subtitled "Sensory Integration," the subject matter has been subdivided and the authors selected with this particular goal in mind. Although the early chapters (on the phylogeny and ontogeny of sensory systems, and on the common properties of sensory systems) are somewhat too abstract to permit many direct behavioral inferences, the focus on behavior has been maintained there too as closely as is now possible. A behavioral orientation is most obvious in the remaining chapters, which layout for each sensory modality in turn what is now known about structure-behavior relationships. The handbook is primarily intended to serve as a ready reference for two types of readers: first, practicing neuroscientists looking for a concise and authori tative treatment of developments outside of their particular specialities; and second, students of one or another branch of neuroscience who need an overview of the persistent questions and current problems surrounding the relation of the perceptual systems to behavior. The requirements imposed by the decision to address these particular audiences are reflected in the scope and style of the chapters as well as in their content.

Available in PDF, EPUB and Kindle. Book excerpt: The theme of this Special Issue is one that is ill-served by the existing neuropsychological literature. A publication that collates reviews of the developmental, physiological, clinical and cognitive aspects of this topic is therefore timely and would prove valuable to clinicians, researchers and students alike. The underlying problem addressed by the invited contributors is how attention is manifest in the intact brain, and how disorders of attention present themselves in the damaged brain. The topics to be covered will range from the physiology of attention (as revealed by single unit recording studies of extra-striate cortex of monkeys and PET scans in humans and low frequency EEG recordings) to disorders of attention after brain damage (e.g. stroke) and chronic pathological disorders of the brain (e.g. dyslexia and mental retardation). The range of contributions to the Special Issue demonstrates that the kinds of attentional processing required are determined by the task in hand. Correspondingly the volume discusses attention in the parietal, temporal and frontal lobes of the human and macaque brain, investigated by clinical, electrophysiological and behavioural methods. Attentional processes are also shown to be distributed in the brain and the effects of diminished attentional capacities which do not result from focal brain lesions are discussed in the context of mental retardation and dyslexia.
Download or read book The Attentive Brain written by Raja Parasuraman and published by MIT Press. This book was released on 2000 with total page 622 pages. Available in PDF, EPUB and Kindle. Book excerpt: Of the myriad tasks that the brain has to perform, perhaps none is as crucial to the performance of other tasks as attention. A central thesis of this book on the cognitive neuroscience of attention is that attention is not a single entity, but a finite set of brain processes that interact mutually and with other brain processes in the performance of perceptual, cognitive, and motor skills.After an introductory part I, the book consists of three parts. Part II, Methods, describes the major neuroscience methods, including techniques used only with animals (anatomical tract tracing, single-unit electrophysiology, neurochemical manipulations), noninvasive human brain-imaging techniques (ERPs, positron emission tomography, and functional magnetic resonance imaging), and studies with brain-damaged individuals. This part also includes a chapter on the computational modeling of attention. Part III, Varieties of Attention, looks at three major components of attention from the cognitive neuroscience perspective: selection, vigilance, and control. It also discusses links to memory and language. Finally, part IV, Development and Pathologies, discusses the application of findings from the previous sections to the analysis of normal and abnormal development and to pathologies of attention such as schizophrenia and attention deficit disorders.

Available in PDF, EPUB and Kindle. Book excerpt: This volume is based on the Symposium on "The Brain and Human Behavior," held in October of 1969 as a part of the centennial observance of the Loyola Uni versity of Chicago. As President of the University, I was pleased to offer the University's support for the organization of this Symposium and to participate in some of its sessions. The volume which I now have the pleasure to introduce employs the materials of the Symposium as a framework. Its chapters constitute updated and greatly expanded versions of the original presentations, edited and organized so as to constitute an integrated picture of Neurosciences and their epistemological aspects. It seems appropriate for me to describe at this time certain features of this Jesuit University and of its Centennial which are particularly pertinent in the context of the present volume. Loyola University of Chicago opened its classes on September 5, 1870 with a faculty of 4 and a student body of 37. Today, Loyola University is the largest in dependent University in Illinois and the largest institution of higher learning under Catholic sponsorship in the United States of America. The University comprises twelve schools and colleges, a faculty of more than 1,600 and a student body of 16,545. As an institution of learning, this University is dedicated to knowledge; but perhaps more particularly than others, it is dedicated to the integration of truth and the knowledge of man as such.
