This book was released on 2016 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Basal Ganglia (BG) are thought to be involved primarily in motor but also in non-motor functions. Unsurprisingly, the BG are shown to be involved in motor dysfunctions such as Parkinson's disease or dystonia. More recent studies suggest the key role of the BG in "non-motor" diseases such as absence epilepsy which is a generalized non-convulsive epilepsy. In these diseases, symptoms accompany various oscillatory patterns of neural activity often synchronized across the BG, cortex and other brain areas. How can the BG support these different kinds of oscillatory patterns?Recent experiments have highlighted the key role of the BG in absence seizures and question the traditional view in which thalamocortical circuits underlie absence seizures. We propose a novel theory according to which the feedbacks of cortical activity through BG make this network bistable and drive the oscillatory patterns of activity occurring during the seizures. Our theory is compatible with virtually all known experimental results and it predicts that well-timed transient excitatory inputs to the cortex advance the termination of absence seizures. We report preliminary experimental results consistent with this prediction.Multiple oscillatory frequencies are observed in Parkinsonian BG such as the frequencies of the limb tremor and the beta oscillations. We show that our model can generate oscillations with multiple timescales which resemble Parkinsonian oscillations. Our theory can model the oscillations in Parkinson's disease and absence epilepsy in a unified framework and points to two scenarios to explain multiple frequencies of pathological and functional oscillations.

Download or read book Neural Organization written by Michael A. Arbib and published by MIT Press. This book was released on 1998 with total page 442 pages. Available in PDF, EPUB and Kindle. Book excerpt: In Neural Organization, Arbib, Erdi, and Szentagothai integrate structural, functional, and dynamical approaches to the interaction of brain models and neurobiologcal experiments. Both structure-based "bottom-up" and function- based "top-down" models offer coherent concepts by which to evaluate the experimental data. The goal of this book is to point out the advantages of a multidisciplinary, multistrategied approach to the brain.Part I of Neural Organization provides a detailed introduction to each of the three areas of structure, function, and dynamics. Structure refers to the anatomical aspects of the brain and the relations between different brain regions. Function refers to skills and behaviors, which are explained by means of functional schemas and biologically based neural networks. Dynamics refers to the use of a mathematical framework to analyze the temporal change of neural activities and synaptic connectivities that underlie brain development and plasticity--in terms of both detailed single-cell models and large-scale network models.In part II, the authors show how their systematic approach can be used to analyze specific parts of the nervous system--the olfactory system, hippocampus, thalamus, cerebral cortex, cerebellum, and basal ganglia--as well as to integrate data from the study of brain regions, functional models, and the dynamics of neural networks. In conclusion, they offer a plan for the use of their methods in the development of cognitive neuroscience."

Download or read book Brain Stimulation written by Irving Reti and published by John Wiley & Sons. This book was released on 2015-05-11 with total page 364 pages. Available in PDF, EPUB and Kindle. Book excerpt: Brain stimulation technologies are both tools to probe brain function and to provide therapeutic options for patients with neuropsychiatric disease where pharmacological options are not viable. Although the field has been in existence for over seventy years, research interest in brain stimulation has been on the rise particularly in the last two decades. Brain Stimulation: Methodologies and Interventions is an introduction to the field of brain stimulation technology and its applications. The book explores how brainstimulating technologies work in the context of brain pathways that mediate normal and abnormal brain function. Chapters cover neuroanatomy and activity dependent changes in neuronal function triggered by brain stimulation, as well as applications of brain stimulation technologies themselves, including noninvasive procedures that rely on convulsive or seizure therapeutics, and non-convulsive therapies such as magnetic and electrical brain stimulation. Authored by an international group of leaders in the field, Brain Stimulation is a valuable resource for both neuroscience researchers and clinicians.

Download or read book Rhythms of the Brain written by G. Buzsáki and published by Oxford University Press. This book was released on 2011 with total page 465 pages. Available in PDF, EPUB and Kindle. Book excerpt: Studies of mechanisms in the brain that allow complicated things to happen in a coordinated fashion have produced some of the most spectacular discoveries in neuroscience. This book provides eloquent support for the idea that spontaneous neuron activity, far from being mere noise, is actually the source of our cognitive abilities. It takes a fresh look at the coevolution of structure and function in the mammalian brain, illustrating how self-emerged oscillatory timing is the brain's fundamental organizer of neuronal information. The small-world-like connectivity of the cerebral cortex allows for global computation on multiple spatial and temporal scales. The perpetual interactions among the multiple network oscillators keep cortical systems in a highly sensitive "metastable" state and provide energy-efficient synchronizing mechanisms via weak links. In a sequence of "cycles," György Buzsáki guides the reader from the physics of oscillations through neuronal assembly organization to complex cognitive processing and memory storage. His clear, fluid writing-accessible to any reader with some scientific knowledge-is supplemented by extensive footnotes and references that make it just as gratifying and instructive a read for the specialist. The coherent view of a single author who has been at the forefront of research in this exciting field, this volume is essential reading for anyone interested in our rapidly evolving understanding of the brain.

Download or read book Dynamic Coordination in the Brain written by Christoph Von Der Malsburg and published by MIT Press. This book was released on 2010-07-09 with total page 367 pages. Available in PDF, EPUB and Kindle. Book excerpt: An examination of how widely distributed and specialized activities of the brain are flexibly and effectively coordinated. A fundamental shift is occurring in neuroscience and related disciplines. In the past, researchers focused on functional specialization of the brain, discovering complex processing strategies based on convergence and divergence in slowly adapting anatomical architectures. Yet for the brain to cope with ever-changing and unpredictable circumstances, it needs strategies with richer interactive short-term dynamics. Recent research has revealed ways in which the brain effectively coordinates widely distributed and specialized activities to meet the needs of the moment. This book explores these findings, examining the functions, mechanisms, and manifestations of distributed dynamical coordination in the brain and mind across different species and levels of organization. The book identifies three basic functions of dynamic coordination: contextual disambiguation, dynamic grouping, and dynamic routing. It considers the role of dynamic coordination in temporally structured activity and explores these issues at different levels, from synaptic and local circuit mechanisms to macroscopic system dynamics, emphasizing their importance for cognition, behavior, and psychopathology.

Download or read book The Noisy Brain written by Edmund T. Rolls and published by . This book was released on 2010-01-28 with total page 334 pages. Available in PDF, EPUB and Kindle. Book excerpt: The activity of neurons in the brain is noisy in that the neuronal firing times are random for a given mean rate. The Noisy Brain shows that this is fundamental to understanding many aspects of brain function, including probabilistic decision-making, perception, memory recall, short-term memory, attention, and even creativity. There are many applications too of this understanding, to for example memory and attentional disorders, aging, schizophrenia, and obsessive-compulsive disorder.
Download or read book The Neurobiological Basis of Suicide written by Yogesh Dwivedi and published by CRC Press. This book was released on 2012-06-25 with total page 485 pages. Available in PDF, EPUB and Kindle. Book excerpt: With recent studies using genetic, epigenetic, and other molecular and neurochemical approaches, a new era has begun in understanding pathophysiology of suicide. Emerging evidence suggests that neurobiological factors are not only critical in providing potential risk factors but also provide a promising approach to develop more effective treatment and prevention strategies. The Neurobiological Basis of Suicide discusses the most recent findings in suicide neurobiology. Psychological, psychosocial, and cultural factors are important in determining the risk factors for suicide; however, they offer weak prediction and can be of little clinical use. Interestingly, cognitive characteristics are different among depressed suicidal and depressed nonsuicidal subjects, and could be involved in the development of suicidal behavior. The characterization of the neurobiological basis of suicide is in delineating the risk factors associated with suicide. The Neurobiological Basis of Suicide focuses on how and why these neurobiological factors are crucial in the pathogenic mechanisms of suicidal behavior and how these findings can be transformed into potential therapeutic applications.
