Book Description
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 Description
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.

Book Description
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."

Book Description
Nearly, 50 years ago, Karl Pribram in a discussion section accompanying MacLean’s proposal of a limbic system, criticized the visceral or limbic brain concept as theoretically too vague and cumbersome. In a recent review of the limbic system, Swanson points to Brodal’s criticism that the discovery of connections of limbic structures with virtually all parts of the nervous system render the concept of the limbic system useless, and better abandoned. Additional dissatisfaction surrounding the limbic brain concept stems from the feeling that it is historically inert (an antiquated 19th century construct). In our current age of neural networks, and parallel distributed process it is of little value, merely an historical curio. So why then this int- duction to limbic brain anatomy? We offer several interrelated rationales behind our labors. Recapitulation in the Service of Education: Although concepts had evolved in the second half of this century which effectively overthrew the idea of relatively isolated hemispheric districts (i. e. striatal, cortical, and limbic), parsing the hemisphere into these three districts was an important preliminary step achieved by our forebears in their efforts to understand the large scale structure of the higher mammalian cerebral hemisphere. An examination of how the limbic brain concept came to be provides an opp- tunity to recapitulate the process of exploration, discovery, and und- standing as it relates to one of these principle hemispheric domains.

Book Description
While this book is intended to be an introduction to the neuroanatomy of the limbic system and to studies of the behavior of animals in which the limbic system is stimulated or damaged, it is primarily intended for advanced students of brain-behavior relationships. I have assumed the reader to have some under standing of the structure of the brain, of basic neurophysiology, and of modern behavioral techniques. It has been written for students in graduate programs in psychobiology, physiological psychology, and the neurosciences, but it also should be of interest to some medical students and to others with catholic interests in the biology of behavior. In the first chapter, I review the structure of the limbic system and in subsequent chapters consider the behavioral effects of lesions and stimulation of components of the limbic system. Supplement information derived from recording the electrical signals of the brain is included where it seems appropriate. The final chapter presents a perspective of the limbic system related to brain stem mechanisms and the neocortex. Understanding the behavioral contributions of the limbic system presupposes under standing how the limbic system interacts with other systems of the brain. v Preface vi Even though there is only one chapter overtly devoted to theoretical issues. various biases of mine influence all chapters. Anyone reading the book with a critical attitude will soon be aware of them. I would like to alert the reader to some of them ahead of time.

Book Description
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.
