Available in PDF, EPUB and Kindle. Book excerpt: Neural Models of Plasticity: Experimental and Theoretical Approaches focuses on the use of theoretical and empirical methods in investigating the role of neuronal plasticity in learning, memory, and complex brain functions. It examines the neuromodulation in relation to associative learning and memory, developmental assembly of various components of learning and memory, cellular and molecular processes contributing to associative and non-associative learning, and higher-order features of classical conditioning. Organized into 19 chapters, this volume begins with an overview of the central pathways mediating conditioning in the marine mollusk Hermissenda and the behavior modified by conditioning, along with the role of neuromodulation in associative learning in this organism. It then proceeds with a discussion of learning and memory in the marine mollusk Aplysia, the Hebb rule for synaptic plasticity, a drive-reinforcement model of neuronal function for predicting classical conditioning phenomena, and the relationship between olfactory processing and associative memory. The reader is also introduced to a neural circuit for classical conditioning of the eyelid closure response, molecular mechanisms and roles of long-term depression in cerebellar function, and functions of neuronal networks in the hippocampus and neocortex in memory. The book concludes with a chapter on models of calcium regulation in neurons. This book is a valuable resource for neurobiologists, psychologists, adaptive systems theorists, and others working in the fields of anatomy, physiology, neurophysiology, molecular biophysics, chemistry, biology, and psychiatry.

Available in PDF, EPUB and Kindle. Book excerpt: Neural Models of Plasticity: Experimental and Theoretical Approaches is an outgrowth of a conference that was held at Woods Hole, Massachusetts, in the spring of 1987. The purpose of that conference was to review recent developments in both areas and to foster communication between those researchers pursuing theoretical approaches and those pursuing more empirical approaches. Contributions have been solicited from individuals who represent both ends of the spectrum of approaches as well as those using a combination of the two. These indicate that our knowledge of the plastic capabilities of the nervous system is accelerating rapidly due to rapid advances in the understanding of basic subcellular and molecular mechanisms of plasticity, and because of the computational capabilities and plastic properties that emerge from neural networks and assemblies. The book contains 19 chapters and opens with a study on the role of the neuromodulator in associative learning of the marine mollusk Hermissend. Subsequent chapters examine topics such as learning and memory in Aplysia; the Hebb rule for synaptic plasticity; olfactory processing and associative memory in the mollusk Limax maximus; simulation of a classically conditioned response; and the neural substrates of memory, focusing on the role of the hippocampus.
Download or read book Spiking Neuron Models written by Wulfram Gerstner and published by Cambridge University Press. This book was released on 2002-08-15 with total page 498 pages. Available in PDF, EPUB and Kindle. Book excerpt: Neurons in the brain communicate by short electrical pulses, the so-called action potentials or spikes. How can we understand the process of spike generation? How can we understand information transmission by neurons? What happens if thousands of neurons are coupled together in a seemingly random network? How does the network connectivity determine the activity patterns? And, vice versa, how does the spike activity influence the connectivity pattern? These questions are addressed in this 2002 introduction to spiking neurons aimed at those taking courses in computational neuroscience, theoretical biology, biophysics, or neural networks. The approach will suit students of physics, mathematics, or computer science; it will also be useful for biologists who are interested in mathematical modelling. The text is enhanced by many worked examples and illustrations. There are no mathematical prerequisites beyond what the audience would meet as undergraduates: more advanced techniques are introduced in an elementary, concrete fashion when needed.

Download or read book Theory of Cortical Plasticity written by Leon N. Cooper and published by World Scientific. This book was released on 2004 with total page 336 pages. Available in PDF, EPUB and Kindle. Book excerpt: This invaluable book presents a theory of cortical plasticity and shows how this theory leads to experiments that test both its assumptions and consequences. It elucidates, in a manner that is accessible to students as well as researchers, the role which the BCM theory has played in guiding research and suggesting experiments that have led to our present understanding of the mechanisms underlying cortical plasticity. Most of the connections between theory and experiment that are discussed require complex simulations. A unique feature of the book is the accompanying software package, Plasticity. This is provided complete with source code, and enables the reader to repeat any of the simulations quoted in the book as well as to vary either parameters or assumptions. Plasticity is thus a research and an educational tool. Readers can use it to obtain hands-on knowledge of the structure of BCM and various other learning algorithms. They can check and replicate our results as well as test algorithms andrefinements of their own.
Download or read book Neural Plasticity written by Peter R. Huttenlocher and published by Harvard University Press. This book was released on 2009-07-01 with total page 285 pages. Available in PDF, EPUB and Kindle. Book excerpt: Neural plasticity--the brain's ability to change in response to normal developmental processes, experience, and injury--is a critically important phenomenon for both neuroscience and psychology. Increasing evidence about the extent of plasticity--long past the supposedly critical first three years--has recently emerged. Neural Plasticity offers the first succinct and lucid integration of this research and its implications. Pointing out the negative and the positive consequences of plasticity, Peter Huttenlocher describes plasticity in children and adults (in normal aging and in response to trauma), in sensory systems, the motor cortex, higher cortical functions, and language development, proceeding system by system, and paying particular attention to the cerebral cortex. One of the book's strengths is its range of references, not only to studies on human subjects but to the experimental study of animal models as well. This book will be a unique contribution to research and to the literature on clinical neuroscience.

Download or read book Anatomy and Plasticity in Large Scale Brain Models written by Markus Butz and published by Frontiers Media SA. This book was released on 2017-01-05 with total page 175 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Spike timing dependent plasticity written by Henry Markram and published by Frontiers E-books. This book was released on with total page 575 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hebb's postulate provided a crucial framework to understand synaptic alterations underlying learning and memory. Hebb's theory proposed that neurons that fire together, also wire together, which provided the logical framework for the strengthening of synapses. Weakening of synapses was however addressed by "not being strengthened", and it was only later that the active decrease of synaptic strength was introduced through the discovery of long-term depression caused by low frequency stimulation of the presynaptic neuron. In 1994, it was found that the precise relative timing of pre and postynaptic spikes determined not only the magnitude, but also the direction of synaptic alterations when two neurons are active together. Neurons that fire together may therefore not necessarily wire together if the precise timing of the spikes involved are not tighly correlated. In the subsequent 15 years, Spike Timing Dependent Plasticity (STDP) has been found in multiple brain brain regions and in many different species. The size and shape of the time windows in which positive and negative changes can be made vary for different brain regions, but the core principle of spike timing dependent changes remain. A large number of theoretical studies have also been conducted during this period that explore the computational function of this driving principle and STDP algorithms have become the main learning algorithm when modeling neural networks. This Research Topic will bring together all the key experimental and theoretical research on STDP.
Download or read book Models of Neural Networks written by Eytan Domany and published by Springer Science & Business Media. This book was released on 1994 with total page 376 pages. Available in PDF, EPUB and Kindle. Book excerpt: The theory of neural nets has two new paradigms: information coding through coherent firing of the neurons and structural feedback. As compared to traditional neural nets, spiking neurons provide an extra degree of freedom: time; this degree of freedom is realized by a coherent spiking of extensively many neurons in the network, a nonlinear phenomenon. The other paradigm, feedback, is a dominant feature of the structural organization of the brain. This volume provides an in-depth analysis of both paradigms starting with an extensive introduction to the ideas used in the subsequent chapters. In addition, one finds a detailed discussion of salient features such as coherent oscillations and their detection, associative binding and segregation, Hebbian learning, and sensory computations in the visual and olfactory cortex. The style and level of this book make it particularly useful for advanced students and researchers looking for an accessible survey of today's theory of neuronal networks.

Download or read book The Rewiring Brain written by Arjen van Ooyen and published by Academic Press. This book was released on 2017-06-23 with total page 586 pages. Available in PDF, EPUB and Kindle. Book excerpt: The adult brain is not as hard-wired as traditionally thought. By modifying their small- or large-scale morphology, neurons can make new synaptic connections or break existing ones (structural plasticity). Structural changes accompany memory formation and learning, and are induced by neurogenesis, neurodegeneration and brain injury such as stroke. Exploring the role of structural plasticity in the brain can be greatly assisted by mathematical and computational models, as they enable us to bridge the gap between system-level dynamics and lower level cellular and molecular processes. However, most traditional neural network models have fixed neuronal morphologies and a static connectivity pattern, with plasticity merely arising from changes in the strength of existing synapses (synaptic plasticity). In The Rewiring Brain, the editors bring together for the first time contemporary modeling studies that investigate the implications of structural plasticity for brain function and pathology. Starting with an experimental background on structural plasticity in the adult brain, the book covers computational studies on homeostatic structural plasticity, the impact of structural plasticity on cognition and cortical connectivity, the interaction between synaptic and structural plasticity, neurogenesis-related structural plasticity, and structural plasticity in neurological disorders. Structural plasticity adds a whole new dimension to brain plasticity, and The Rewiring Brain shows how computational approaches may help to gain a better understanding of the full adaptive potential of the adult brain. The book is written for both computational and experimental neuroscientists. Reviews the current state of knowledge of structural plasticity in the adult brain Gives a comprehensive overview of computational studies on structural plasticity Provides insights into the potential driving forces of structural plasticity and the functional implications of structural plasticity for learning and memory Serves as inspiration for developing novel treatment strategies for stimulating functional repair after brain damage
Download or read book Post Lesion Neural Plasticity written by Hans Flohr and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 692 pages. Available in PDF, EPUB and Kindle. Book excerpt: Neural networks are not rigidly wired but rather highly plastic structures, the functional architecture of which can be actively reorganized in response to external or internal events. Lesions of such networks induce plastic processes which in time may lead to a recovery of the initially disrupted function. This type of neural plasticity is the main focus of the book, which presents a broad spectrum of experimental paradigms for lesion-induced plasticity as in the spinal cord, the vestibular, oculomotor, visual and olfactory system, the cerebellum and the cerebral cortex, including recent methodological developments. Concepts and perspectives in understanding neural plasticity are reported in reviews and original research reports and are thoroughly discussed.
