Book Synopsis Neural Plasticity and Memory by : Federico Bermudez-Rattoni
Download or read book Neural Plasticity and Memory written by Federico Bermudez-Rattoni and published by CRC Press. This book was released on 2007-04-17 with total page 368 pages. Available in PDF, EPUB and Kindle. Book excerpt: A comprehensive, multidisciplinary review, Neural Plasticity and Memory: From Genes to Brain Imaging provides an in-depth, up-to-date analysis of the study of the neurobiology of memory. Leading specialists share their scientific experience in the field, covering a wide range of topics where molecular, genetic, behavioral, and brain imaging techniques have been used to investigate how cellular and brain circuits may be modified by experience. In each chapter, researchers present findings and explain their innovative methodologies. The book begins by introducing key issues and providing a historical overview of the field of memory consolidation. The following chapters review the putative genetic and molecular mechanisms of cell plasticity, elaborating on how experience could induce gene and protein expression and describing their role in synaptic plasticity underlying memory formation. They explore how putative modifications of brain circuits and synaptic elements through experience can become relatively permanent and hence improve brain function. Interdisciplinary reviews focus on how nerve cell circuitry, molecular expression, neurotransmitter release, and electrical activity are modified during the acquisition and consolidation of long-term memory. The book also covers receptor activation/deactivation by different neurotransmitters that enable the intracellular activation of second messengers during memory formation. It concludes with a summary of current research on the modulation and regulation that different neurotransmitters and stress hormones have on formation and consolidation of memory.
Book Synopsis Synaptic Plasticity in Pain by : Marzia Malcangio
Download or read book Synaptic Plasticity in Pain written by Marzia Malcangio and published by Springer Science & Business Media. This book was released on 2009-05-28 with total page 500 pages. Available in PDF, EPUB and Kindle. Book excerpt: Primary sensory neurons respond to peripheral stimulation and project to the spinal cord. Specifically, the population of neurons which respond to damaging stimuli terminate in the superficial layers of the dorsal horn. Therefore, the dorsal horns constitute the first relay site for nociceptive fibre terminals which make synaptic contacts with second order neurons. It has recently become clear that the strength of this first pain synapse is plastic and modifiable by several modulators, including neuronal and non-neuronal regulators, and studies on the fundamental processes regulating the plasticity of the first pain synapse have resulted in the identification of new targets for the treatment of chronic pain. This book will be of interest to a wide readership in the pain field.
Book Synopsis Plasticity of GABAergic Synapses by : Andrea Barberis
Download or read book Plasticity of GABAergic Synapses written by Andrea Barberis and published by Frontiers Media SA. This book was released on 2016-01-22 with total page 177 pages. Available in PDF, EPUB and Kindle. Book excerpt: Learning and memory are believed to depend on plastic changes of neuronal circuits due to activity-dependent potentiation or depression of specific synapses. During the last two decades, plasticity of brain circuits was hypothesized to mainly rely on the flexibility of glutamatergic excitatory synapses, whereas inhibitory synapses were assumed relatively invariant, to ensure stable and reliable control of the neuronal network. As a consequence, while considerable efforts were made to clarify the main mechanisms underlying plasticity at excitatory synapses, the study of the cellular/molecular mechanisms of inhibitory plasticity has received much less attention. Nevertheless, an increasing body of evidence has revealed that inhibitory synapses undergo several types of plasticity at both pre- and postsynaptic levels. Given the crucial role of inhibitory interneurons in shaping network activities, such as generation of oscillations, selection of cell assemblies and signal integration, modifications of the inhibitory synaptic strength represents an extraordinary source of versatility for the fine control of brain states. This versatility also results from the rich diversity of GABAergic neurons in several brain areas, the specific role played by each inhibitory neuron subtype within a given circuit, and the heterogeneity of the properties and modulation of GABAergic synapses formed by specific interneuron classes. The molecular mechanisms underlying the potentiation or depression of inhibitory synapses are now beginning to be unraveled. At the presynaptic level, retrograde synaptic signaling was demonstrated to modulate GABA release, whereas postsynaptic forms of plasticity involve changes in the number/gating properties of GABAA receptors and/or shifts of chloride gradients. In addition, recent research indicates that GABAergic tonic inhibition can also be plastic, adding a further level of complexity to the control of the excitatory/inhibitory balance in the brain. The present Topic will focus on plasticity of GABAergic synapses, with special emphasis on the molecular mechanisms of plasticity induction and/or expression.

Book Synopsis Extrasynaptic GABAA Receptors by : Adam C. Errington
Download or read book Extrasynaptic GABAA Receptors written by Adam C. Errington and published by Springer. This book was released on 2014-09-22 with total page 295 pages. Available in PDF, EPUB and Kindle. Book excerpt: GABA is the principal inhibitory neurotransmitter in the CNS and acts via GABAA and GABAB receptors. Recently, a novel form of GABAA receptor-mediated inhibition, termed “tonic” inhibition, has been described. Whereas synaptic GABAA receptors underlie classical “phasic” GABAA receptor-mediated inhibition (inhibitory postsynaptic currents), tonic GABAA receptor-mediated inhibition results from the activation of extrasynaptic receptors by low concentrations of ambient GABA. Extrasynaptic GABAA receptors are composed of receptor subunits that convey biophysical properties ideally suited to the generation of persistent inhibition and are pharmacologically and functionally distinct from their synaptic counterparts. This book highlights ongoing work examining the properties of recombinant and native extrasynaptic GABAA receptors and their preferential targeting by endogenous and clinically relevant agents. In addition, it emphasizes the important role of extrasynaptic GABAA receptors in GABAergic inhibition throughout the CNS and identifies them as a major player in both physiological and pathophysiological processes.

Book Synopsis Developmental Plasticity of Inhibitory Circuitry by : Sarah L. Pallas
Download or read book Developmental Plasticity of Inhibitory Circuitry written by Sarah L. Pallas and published by Springer. This book was released on 2009-12-09 with total page 190 pages. Available in PDF, EPUB and Kindle. Book excerpt: Neuroscience has long been focused on understanding neural plasticity in both development and adulthood. Experimental work in this area has focused almost entirely on plasticity at excitatory synapses. A growing body of evidence suggests that plasticity at inhibitory GABAergic and glycinergic synapses is of critical importance during both development and aging. The book brings together the work of researchers investigating inhibitory plasticity at many levels of analysis and in several different preparations. This topic is of wide relevance across a number of different areas of research in neuroscience and neurology. Medical problems such as epilepsy, mental illness, drug abuse, and movement disorders can result from malfunctioning inhibitory circuits. Further, the maturation of inhibitory circuits may trigger the onset of critical periods of neural circuit plasticity, raising the possibility that such plastici periods could be reactivated for medical benefit by manipulating inhibitory circuitry.

Book Synopsis Synaptic Plasticity in the Hippocampus by : Helmut L. Haas
Download or read book Synaptic Plasticity in the Hippocampus written by Helmut L. Haas and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 219 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the second time that I have had the honor of opening an interna tional symposium dedicated to the functions of the hippocampus here in Pecs. It was a pleasure to greet the participants in the hope that their valuable contributions will make this meeting a tradition in this town. As one of the hosts of the symposium, I had the sorrowful duty to remind you of the absence of a dear colleague, Professor Graham God dard. His tragic and untimely death represents the irreparable loss of both a friend and an excellent researcher. This symposium is dedicated to his memory. If I compare the topics of the lectures of this symposium with those of the previous one, a striking difference becomes apparent. A dominating tendency of the previous symposium was to attempt to define hippocam pal function or to offer data relevant to supporting or rejecting existing theoretical positions. No such tendency is reflected in the titles of the present symposium, in which most of the contributions deal with hip pocampal phenomena at the most elementary level. Electrical, biochemi cal, biophysical, and pharmacological events at the synaptic, membrane, or intracellular level are analyzed without raising the question of what kind of integral functions these elementary phenomena are a part of.

Book Synopsis Inhibitory Function in Auditory Processing by : R. Michael Burger
Download or read book Inhibitory Function in Auditory Processing written by R. Michael Burger and published by Frontiers Media SA. This book was released on 2015-10-28 with total page 233 pages. Available in PDF, EPUB and Kindle. Book excerpt: There seems little doubt that from the earliest evolutionary beginnings, inhibition has been a fundamental feature of neuronal circuits - even the simplest life forms sense and interact with their environment, orienting or approaching positive stimuli while avoiding aversive stimuli. This requires internal signals that both drive and suppress behavior. Traditional descriptions of inhibition sometimes limit its role to the suppression of action potential generation. This view fails to capture the vast breadth of inhibitory function now known to exist in neural circuits. A modern perspective on inhibitory signaling comprises a multitude of mechanisms. For example, inhibition can act via a shunting mechanism to speed the membrane time constant and reduce synaptic integration time. It can act via G-protein coupled receptors to initiate second messenger cascades that influence synaptic strength. Inhibition contributes to rhythm generation and can even activate ion channels that mediate inward currents to drive action potential generation. Inhibition also appears to play a role in shaping the properties of neural circuitry over longer time scales. Experience-dependent synaptic plasticity in developing and mature neural circuits underlies behavioral memory and has been intensively studied over the past decade. At excitatory synapses, adjustments of synaptic efficacy are regulated predominantly by changes in the number and function of postsynaptic glutamate receptors. There is, however, increasing evidence for inhibitory modulation of target neuron excitability playing key roles in experience-dependent plasticity. One reason for our limited knowledge about plasticity at inhibitory synapses is that in most circuits, neurons receive convergent inputs from disparate sources. This problem can be overcome by investigating inhibitory circuits in a system with well-defined inhibitory nuclei and projections, each with a known computational function. Compared to other sensory systems, the auditory system has evolved a large number of subthalamic nuclei each devoted to processing distinct features of sound stimuli. This information once extracted is then re-assembled to form the percept the acoustic world around us. The well-understood function of many of these auditory nuclei has enhanced our understanding of inhibition's role in shaping their responses from easily distinguished inhibitory inputs. In particular, neurons devoted to processing the location of sound sources receive a complement of discrete inputs for which in vivo activity and function are well understood. Investigation of these areas has led to significant advances in understanding the development, physiology, and mechanistic underpinnings of inhibition that apply broadly to neuroscience. In this series of papers, we provide an authoritative resource for those interested in exploring the variety of inhibitory circuits and their function in auditory processing. We present original research and focused reviews touching on development, plasticity, anatomy, and evolution of inhibitory circuitry. We hope our readers will find these papers valuable and inspirational to their own research endeavors.
