Available in PDF, EPUB and Kindle. Book excerpt: This volume records the proceedings of a Limbic System Sympos ium held at the University of Toronto, November 5-6th, 1976 as a satellite event to the Sixth Annual Meeting of the Society of Neuroscience. The Symposium was designed in part as a tribute to James Papez on the 40th anniversary of the publication of his epochal paper "A Proposed Mechanism of Emotion". Papers by MacLean, Yakovlev, and Angevine provide personal recollections of Papez and an assessment of the significant contri bution he made to breaking down the still formidable barriers that separate our concepts of brain, mind, emotion, and behavior. Against this background subsequent speakers presented new information that further illuminates the anatomical, physiological and biochemical mechanisms underlying limbic system function. Viewed in juxtaposition this new information from "disparate" fields of neuroscience provides an increasingly coherent picture of the neuronal organization subserving a dynamic limbic system that we can now begin to visualize in operational and transactional terms. The final section of the symposium focusses on the recently identified "kindling" phenomenon which is viewed as a general model of neural plasticity and more particularly as a model of experi mentally induced limbic system dysfunction. Using this model it is possible to display, analyse, and experimentally manipulate long lasting changes in limbic system activity, which develop over ex tended periods of time and are expressed in a variety of behavioral end points involving learning and memory, seizure activity, and changes in emotionality and behavior.

Book excerpt: 107 with treatments that affect the arousal of the animals is also implied on the basis of the behavioral changes induced in the lesioned animals by amphetamine administration and by changes in the motivational circumstances under which the animals are tested. Studies of the effects of cingulate lesions in the rat have involved the production of midline cortical damage. Unfortunately, as reported in the previous chapter, the midline cortex of the rat is not comparable to the midline cortex of other animals as defined on the basis of the fibers it receives from the thalamus. In addition, lesions of the midline cortex, whether in the rat or in other species, are likely to interfere with fibers of the neural systems in or near it. These include the cingulum bundle and the supracallosal fibers of the fornix. Norepi nephrine-containing fibers also pass through this region in or near the cingulum bundle. These fibers ascend through the anterior dor solateral septal area and turn up and back to pass through the midline regions and innervate the entire medial cortex (Morrison, Molliver, & Grzanna, 1979). Lesions in this area reduce the norepinephrine distribution throughout the rostrocaudal extent of the medial cortex. A similar problem results from destruction to the anterior cortical regions. Lesions in that region could reduce the norepinephrine sup plies of the entire dorsolateral cortex.

Download or read book Discovering the Brain written by National Academy of Sciences and published by National Academies Press. This book was released on 1992-01-01 with total page 195 pages. 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 Brain and Behaviour written by Bryan Kolb and published by SAGE. This book was released on 2016-10-18 with total page 379 pages. Available in PDF, EPUB and Kindle. Book excerpt: Revisiting the Classic Studies is a series of texts that introduces readers to the studies in psychology that changed the way we think about core topics in the discipline today. It provokes students to ask more interesting and challenging questions about the field by encouraging a deeper level of engagement both with the details of the studies themselves and with the nature of their contribution. Edited by leading scholars in their field and written by researchers at the cutting edge of these developments, the chapters in each text provide details of the original works and their theoretical and empirical impact, and then discuss the ways in which thinking and research has advanced in the years since the studies were conducted. Brain and Behaviour: Revisiting the Classic Studies traces 17 ground-breaking studies by researchers such as Gage, Luria, Sperry, and Tulving to re-examine and reflect on their findings and engage in a lively discussion of the subsequent work that they have inspired. Suitable for students on neuropsychology courses at all levels, as well as anyone with an enquiring mind.

Download or read book Jasper's Basic Mechanisms of the Epilepsies written by Jeffrey Noebels and published by OUP USA. This book was released on 2012-06-29 with total page 1258 pages. Available in PDF, EPUB and Kindle. Book excerpt: Jasper's Basic Mechanisms, Fourth Edition, is the newest most ambitious and now clinically relevant publishing project to build on the four-decade legacy of the Jasper's series. In keeping with the original goal of searching for "a better understanding of the epilepsies and rational methods of prevention and treatment.", the book represents an encyclopedic compendium neurobiological mechanisms of seizures, epileptogenesis, epilepsy genetics and comordid conditions. Of practical importance to the clinician, and new to this edition are disease mechanisms of genetic epilepsies and therapeutic approaches, ranging from novel antiepileptic drug targets to cell and gene therapies.
