Thalamic Networks for Relay and Modulation is the third in a series that springs from an idea of Giorgio Macchi who wished to establish periodical updates on thalamic research by bringing to Italy investigators who would engage in an international sharing of ideas and experiences. It reflects the renewed interest in the modulation of thalamic relay activity by intrinsic and extrinsic sources, while continuing to underscore the essential role of the thalamus as the gatekeeper of the cerebral cortex and of the pathways to perception. The papers that form the substance of this book were presented at a Symposium held at the Catholic University, Rome, Italy, in September 1992, as a Satellite to the 15th Annual Meeting of the European Neuroscience Association. The volume is organized into four parts. Part I is basically concerned with developmental and evolutionary approaches. Part II highlights relay functions of visual, motor, and somatosensory relay nuclei and relay functions of the intralaminar nuclei. Part III deals primarily with the pharmacology of thalamic neurons. Part IV emphasizes the mechanisms that underlie the functional assembly of thalamic cells into collectively acting ensembles, largely revealed in rhythmic oscillations, and on the behavioral manifestations that accompany them.

This volume is comprised of the majority of lecture presentations and a few select posters presented at the International Workshop, "Basal Ganglia and Thalamus in Health and Movement Disorders," held in Moscow, Russia, on May 29-31, 2000. The International Committee responsible for organizing this workshop included Alexander Konovalov, Director, Burdenko Institute of Neurosurgery of the Russian Academy of Medical Sciences, Mahlon DeLong, Chair, Department of Neurology, Emory University, Atlanta, USA, Alim Louis Benabid, Chief, Neurosurgery Service, University of Joseph Fourrier, Grenoble, France, and the two undersigned. The workshop was conceived out of a desire to provide a forum for discussions of both basal ganglia-and motor thalamus-related issues by bringing together basic scientists and clinicians representing different disciplines, research directions, and philosophies. The primary goals were to encourage an exchange of information and ideas in an informal environment, to stimulate integration of the data from different disciplines, and to identifY controversial issues and the most essential questions to be addressed in future research.

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

This volume is the second in the planned coverage of the neurochemical circuitry of the primate central nervous system. While this volume contains only two chapters, their topics and the extraordinarily comprehensive coverage with which the authors have dealt with their topics, will nevertheless contribute equal amounts of knowledge, wisdom, and opportunities for future research extensions as have every volume in this unique series. As such, these chapters extend the goals of this primate series to develop a broad coverage of human and non-human primate chemical neuroanatomic details in a volume which makes clear the known and desirable appreciation for differences between and among subsets of primate brains.The first chapter covers the primate thalamus with equal emphases on new world, old world, pro-simian and human anatomic details and their differences. The second undertakes a comparably comprehensive examination of one of the most intensively studied regions of the primate brain, namely the primate visual cortex. While much has been studied, both chapters also reveal how much remains for future efforts in these enormously important regions which are the archetypes of primate sub-cortical and cortical function.

In his trademark, revolutionary style, Dr. Goldstein uses his model of neural dysregulation to incorporate basic neuroscience research into pathophysiology and treatment. Betrayal by the Brain presents a comprehensive thesis that clearly defines the biological basis for many of the varied symptoms experienced by chronic fatigue syndrome patients. Dr. Goldstein provides a rationale for the use of symptomatic therapies that have worked in many CFS patients. Betrayal by the Brain is a valuable handbook to assist the medical professional in the diagnosis and treatment of the many patients afflicted with this illness. It is of great value to medical professionals as well as academic researchers in psychiatry, biobehavioral sciences, psychoneuroimmunology, and pain management.Dr. Goldstein has added layers of regulation to the limbic system that help further explain limbic dysfunction in neurosomatic disorders, and he suggests novel methods of remediation. Betrayal by the Brain represents integrative thinking and the latest research and discoveries by Dr. Goldstein on neurosomatic disorders--the most common group of illnesses for which patients consult physicians.

1. 1 Purpose and Plan of This Review This review is focused on the topography and connections of some of the neuron populations that determine the manual dexterity of the macaque monkey. The populations selected for examination are the following: 1. The corticospinal neuron populations 2. The thalamocortical and corticothalamic neuron populations associated with the sensorimotor cortex 3. The ipsilateral cortical connections of the sensorimotor cortex These neuron populations have been chosen because of their obvious rel evance to the directed, intelligent use of the hands, but also because of their anatomical and functional interdependence. Corticospinal neuron populations transmit a complex, orchestrated output from a number of different regions of cerebral cortex to the neuron populations in every segment of the spinal cord, and this output includes the command information defining the intended manual action. The thalamocortical complex is especially concerned with the transmis sion and modulation or filtering of (a) visual, tactile, proprioceptive, vestibular, and auditory information to the cerebral cortex and (b) information from the cerebellum, basal ganglia, limbic system, and brain stem which is relevant to sensorimotor behavior. Finally, the extensive ipsilateral cortical connections constitute a major part of the supraspinal circuitry which coordinates the contri butions of all the cortical neuron popUlations contributing to intelligent sen sorimotor behavior and, in particular, transmits the cross talk between those cortical neuron populations which shape and control the dextrous handling of objects within reach.

Pain is a subject of significant scientific and clinical interest. This has resulted both from realistic rodent models, and the publication of imaging, psychological and pharmacological studies in humans. Investigators studying rodents refer to anatomical and physiological studies in non-human primates to make their results relevant to humans. Psychophysical and pharmacological studies in humans are interpreted in terms of anatomical and physiological studies in animals; primarily evidence from rodents and cats. There are significant differences in pain mechanisms between these species and primates. Over 20 years of imaging studies have demonstrated the activation of human cortical and subcortical structures in response to painful stimuli. Interpretation of these results relies upon an understanding of the anatomy and physiology of these structures in primates. Jones, Lenz, Casey and Willis review the anatomy and physiology of nociception in monkeys and humans, and provide a firm basis for interpreting studies in humans.

The present edition of The Human Central Nervous System differs considerably from its predecessors. In previous editions, the text was essentially confined to a section dealing with the various functional systems of the brain. This section, which has been rewritten and updated, is now preceded by 15 newly written chapters, which introduce the pictorial material of the gross anatomy, the blood vessels and meninges and the microstructure of its various parts and deal with the development, topography and functional anatomy of the spinal cord, the brain stem and the cerebellum, the diencephalon and the telencephalon. Great pains have been taken to cover the most recent concepts and data. As suggested by the front cover, there is a focus on the evolutionary development of the human brain. Throughout the text numerous correlations with neuropathology and clinical n- rology have been made. After much thought, we decided to replace the full Latin terminology, cherished in all previous editions, with English and Anglicized Latin terms. It has been an emotional farewell from beautiful terms such as decussatio hipposideriformis W- nekinkii and pontes grisei caudatolenticulares. Not only the text, but also the p- torial material has been extended and brought into harmony with the present state of knowledge. More than 230 new illustrations have been added and many others have been revised. The number of macroscopical sections through the brain has been extended considerably. Together, these illustrations now comprise a complete and convenient atlas for interpreting neuroimaging studies.

The thalamus is often described as a relay. Typified by sensory pathways, this concept leads to thalamic nuclei being viewed as areas that passively streams information from a single source to the cortex, without affecting the nature of that information. However, diverse intrathalamic connections, the varying synaptic and membrane properties of thalamic neurons and the large number of inputs from non-sensory sources make the idea that the thalamus is just a passive relay unlikely. Furthermore, a large number of thalamic nuclei are not primarily driven by sensory signals nor do they exclusively target the cortex, meaning the thalamus must do more than simply pass sensory signals to the cortex. Finally, there is a wealth of research demonstrating that the thalamus does indeed function in ways that are not captured by the concept of a simple relay. So why, given all of this, is the primary paradigm for describing the thalamus, a relay? This Research Topic covers original research, reviews and hypotheses on thalamic function that explore the concept that the thalamus performs computational tasks other than simply passively relaying information.

Supercomputing facilities are becoming increasingly available for simulating activity dynamics in large-scale neuronal networks. On today's most advanced supercomputers, networks with up to a billion of neurons can be readily simulated. However, building biologically realistic, full-scale brain models requires more than just a huge number of neurons. In addition to network size, the detailed local and global anatomy of neuronal connections is of crucial importance. Moreover, anatomical connectivity is not fixed, but can rewire throughout life (structural plasticity)—an aspect that is missing in most current network models, in which plasticity is confined to changes in synaptic strength (synaptic plasticity). The papers in this Ebook, which may broadly be divided into three themes, aim to bring together high-performance computing with recent experimental and computational research in neuroanatomy. In the first theme (fiber connectivity), new methods are described for measuring and data-basing microscopic and macroscopic connectivity. In the second theme (structural plasticity), novel models are introduced that incorporate morphological plasticity and rewiring of anatomical connections. In the third theme (large-scale simulations), simulations of large-scale neuronal networks are presented with an emphasis on anatomical detail and plasticity mechanisms. Together, the articles in this Ebook make the reader aware of the methods and models by which large-scale brain networks running on supercomputers can be extended to include anatomical detail and plasticity.
