Available in PDF, EPUB and Kindle. Book excerpt: In the past half century since the Vogts stimulated investigations on the anatomi cal relationships between cortex and subcortical structures, a voluminous literature has developed on the thalamus. Although much of this writing has been based upon studies of sub-human primates and carnivora, the prime goal of most investi gators has been to elucidate clinical experience. And indeed, these researches have enlightened the neurologist. From the beginning of anatomical studies of the thalamus, anatomists have sought a meaningful parcellation of the thalamus on the basis of both topography and cellular morphology. However, as the internal organization of the thalamus changes greatly in phylogeny, a topographical designation of thalamic divisions in different species loses its significance. Hence, the detailed descriptions of the nuclear configuration of carnivora, which appeared from the laboratories of Huber and Crosby, could not be readily applied to the thalamus of monkey or man. This has led to the introduction of different and more or less specific terminologies for each species rendering attempts at homologies difficult, if not impossible. Recogniz ing the changes in conceptualization of the thalamus and the advances in neuro anatomical knowledge, Dr. Van Buren has tackled the formidable tasks of bringing the thalamic nomenclature up to date. He has based his parcellation of the thala mus upon the histological morphology of the neuronal components, which are modified, to some extent at least, by the fiber tracts traversing the area.

Available in PDF, EPUB and Kindle. Book excerpt: Imagine a seminar in which four smart people address the significance of a deep and central brain structure, the thalamus, in its relationship to the overlying cerebral cortex. Among the four, we hear from an economist, a mathematician, and two scientists. For medical or neuroscience students, or for trainees in neurology, neurosurgery, and psychiatry, Edison K. Miyawaki describes relevant thalamocortical anatomy in humans and other vertebrates. He summarizes known thalamocortical connections in their rich complexity. Thalamus and its Cortex is an experiment in teaching replete with old (but still good) and contemporary insights about the relationship between cortex and subcortex.

Available in PDF, EPUB and Kindle. Book excerpt: Cognitive processing is commonly conceptualized as being restricted to the cerebral cortex. Accordingly, electrophysiology, neuroimaging and lesion studies involving human and animal subjects have almost exclusively focused on defining roles for cerebral cortical areas in cognition. Roles for the thalamus in cognition have been largely ignored despite the fact that the extensive connectivity between the thalamus and cerebral cortex gives rise to a closely coupled thalamo-cortical system. However, in recent years, growing interest in the thalamus as much more than a passive sensory structure, as well as methodological advances such as high-resolution functional magnetic resonance imaging of the thalamus and improved electrode targeting to subregions of thalamic nuclei using electrical stimulation and diffusion tensor imaging, have fostered research into thalamic contributions to cognition. Evidence suggests that behavioral context modulates processing in primary sensory, or first-order, thalamic nuclei (for example, the lateral geniculate and ventral posterior nuclei), allowing attentional filtering of incoming sensory information at an early stage of brain processing. Behavioral context appears to more strongly influence higher-order thalamic nuclei (for example, the pulvinar and mediodorsal nucleus), which receive major input from the cortex rather than the sensory periphery. Such higher-order thalamic nuclei have been shown to regulate information transmission in frontal and higher-order sensory cortex according to cognitive demands. This Research Topic aims to bring together neuroscientists who study different parts of the thalamus, particularly thalamic nuclei other than the primary sensory relays, and highlight the thalamic contributions to attention, memory, reward processing, decision-making, and language. By doing so, an emphasis is also placed on neural mechanisms common to many, if not all, of these cognitive operations, such as thalamo-cortical interactions and modulatory influences from sources in the brainstem and basal ganglia. The overall view that emerges is that the thalamus is a vital node in brain networks supporting cognition.

Available in PDF, EPUB and Kindle. Book excerpt: The brain ... There is no other part of the human anatomy that is so intriguing. How does it develop and function and why does it sometimes, tragically, degenerate? The answers are complex. In Discovering the Brain, science writer Sandra Ackerman cuts through the complexity to bring this vital topic to the public. The 1990s were declared the "Decade of the Brain" by former President Bush, and the neuroscience community responded with a host of new investigations and conferences. Discovering the Brain is based on the Institute of Medicine conference, Decade of the Brain: Frontiers in Neuroscience and Brain Research. Discovering the Brain is a "field guide" to the brainâ€"an easy-to-read discussion of the brain's physical structure and where functions such as language and music appreciation lie. Ackerman examines: How electrical and chemical signals are conveyed in the brain. The mechanisms by which we see, hear, think, and pay attentionâ€"and how a "gut feeling" actually originates in the brain. Learning and memory retention, including parallels to computer memory and what they might tell us about our own mental capacity. Development of the brain throughout the life span, with a look at the aging brain. Ackerman provides an enlightening chapter on the connection between the brain's physical condition and various mental disorders and notes what progress can realistically be made toward the prevention and treatment of stroke and other ailments. Finally, she explores the potential for major advances during the "Decade of the Brain," with a look at medical imaging techniquesâ€"what various technologies can and cannot tell usâ€"and how the public and private sectors can contribute to continued advances in neuroscience. This highly readable volume will provide the public and policymakersâ€"and many scientists as wellâ€"with a helpful guide to understanding the many discoveries that are sure to be announced throughout the "Decade of the Brain."

Download or read book The Thalamus written by Edward G. Jones and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 916 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is now more than fifty years since Sir Wilfrid Le Gros Clark (1932a) published his Arris and Gale lectures on the structure and connections of the thalamus. This authoritative overview came at a time when thalamic studies were passing from a descriptive to an experimental phase and, in his review, Le Gros Clark was able to cover virtually every aspect of the organization and development and much of the comparative anatomy of the thalamus then known. It is also approaching a half-century since A. Earl Walker (1938a) wrote The Primate Thalamus, which was strongly experimental, but with many Clinical in sights, and which he described as "an attempt to elucidate the role of the thalamus in sensation. " The intervening years have seen published a few reports of con ferences on aspects of thalamic organization and function but no monographs comparable to those of Le Gros Clark or Walker. Perhaps this is understandable when one considers, not so much the enormity of the new data that have been added, but rather the emphasis upon individual thalamic nuclei as components of separate functional systems, not all of them sensory. It is probably also true to say that studies in the commoner experimental animals such as the rat, cat, and monkey have been so productive in their own right that there was little interest in making an across-species synthesis.

Available in PDF, EPUB and Kindle. Book excerpt: Two leading authorities on thalamocortical connections consider how the neural circuits of the brain relate to our actions and perceptions. In this book, two leading authorities on the thalamus and its relationship to cortex build on their earlier findings to arrive at new ways of thinking about how the brain relates to the world, to cognition, and behavior. Based on foundations established earlier in their book Exploring the Thalamus and Its Role in Cortical Function, the authors consider the implications of these ground rules for thalamic inputs, thalamocortical connections, and cortical outputs. The authors argue that functional and structural analyses of pathways connecting thalamus and cortex point beyond these to lower centers and through them to the body and the world. Each cortical area depends on the messages linking it to body and world. These messages relate to the way we act and think; each cortical area receives thalamic inputs and has outputs to motor centers. Sherman and Guillery go on to discuss such topics as the role of branching axons that carry motor instructions as well as copies of these motor instructions for relay to cortex under the control of the thalamic gate. This gate allows the thalamus to control the passage of information on the basis of which cortex relates to the rest of the nervous system.

Download or read book Exploring the Thalamus written by S. Murray Sherman and published by Elsevier. This book was released on 2001-01-02 with total page 331 pages. Available in PDF, EPUB and Kindle. Book excerpt: The thalamus is a group of cells placed centrally in the brain that serve a critical role in controlling how both sensory and motor signals are passed from one part of the cerebral cortex to another. Essentially, all information reaching the cerebral cortex and thus consciousness is relayed through the thalamus. The role of the thalamus in controlling the flow of information (such as visual, auditory, and motor) to the cortex has only recently begun to be understood. This book provides an in-depth look at the function of the thalamus and its role as relayer of information to the cerebral cortex. The authors explore how the thalamus controls messages that are passed to the cortex and they introduce the novel suggestion that the thalamus serves a critical role in controlling how messages pass from one part of the cortex to another. Exploring the Thalamus is a comprehensive, up-to-date reference for researchers. It discusses problems concerning the function and structure of the thalamus and concludes each chapter with thought-provoking questions regarding future research. Focuses on thalamocortical interrelationships Discusses important problems concerning the function and structure of the thalamus Concludes each chapter with thought-provoking questions requiring future research
