Download or read book The Structure of Transient Memory in a Simple Model of Inhibitory Neural Feedback written by Richard B. Watson and published by . This book was released on 2014 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Brains must perform essential tasks of information manipulation, storage and integration. Neural circuits are believed to carry out these tasks, in part, by virtue of their connectivity: anatomical configurations that pattern action potentials in particular ways. Feedback inhibition circuits are a specific variety of neural connectivity known to be statistically overrepresented throughout the brain in a range of species. Yet analysis of the mechanisms by which useful function emerges from such structure is lacking. We analytically studied a simple model of delayed inhibitory feedback to elucidate this question. Here we describe new results linking structural parameters of the neural circuit to changes in its behavioral dynamics and ultimately in its correlative patterns of spiking. Such correlation in turn, is shown to provide the substrate for transient memory, useful to integrate information corresponding to input temporally and perform computation through time. Integrator neurons alone are incapable of introducing correlation in the sequence of inter- spike intervals (ISIs) they emit. However, in the system we investigate, inhibition causally impacts the neuron at a future time, opening the door to possible statistical dependency. Here, we examine analytically the dynamics underlying this dependency structure. We study the system first with the more tractable case of constant current (DC) input. For small input and short delays, the dynamics limit the ISI dependency to Markov order one. In these cases we are able to explore the behavior with a with a one-dimensional return map. However, if the feedback delay is long enough or the input is strong enough, Markov order increases and additional dimensions are necessary to explain more complex behavior. We examine the bounds of such behaviors in parameter space and inspect it more closely as a series of bifurcations induced by larger delays and increased input - each bifurcation revealing a regime of higher period trajectories capable of embedding more information. Building on this analytical understanding of the simpler case, we advance to studying stochastic input in the form of Poisson distributed excitatory post-synaptic potentials (EPSPs). Stochastic return plots, in direct analogy with the return maps of the constant input case, provide insight into first order correlations. However, larger delays and increased input once again expand the output sequence Markov order. The accessible state space and hence the informational storage capacity of the system grows. We use computational mechanics [Cru12] to further dissect the behavioral character of the feedback inhibition model circuit under stochastic input for arbitrary orders of dependence. We find that the underlying states of the system are arranged in layers, where outer layers are only visitable from states in one beneath. Each layer, made available by longer feedback delays or stronger input, introduces a boost in memory to the system. As memory increases, the circuit gains capacity to retain and integrate information about longer sequences of past input. This work demonstrates one minimal mechanism - potentially in operation throughout the brain in a broad range of species - by which information in spikes may be transiently stored and subsequently integrated within neural circuits. Such a mechanism of transient memory may prove to be an important, if not essential, means by which organisms compute with signals through time.

This book was released on 2014-11-07 with total page 368 pages. Available in PDF, EPUB and Kindle. Book excerpt: Understanding how the brain functions is one of the most ambitious current scientific goals. This challenge will only be accomplish by a multidisciplinary approach involving genetics, molecular biology, optics, ethology, neurobiology and mathematics and using tractable model systems. The zebrafish larva is a transparent genetically tractable small vertebrate, ideal for the combination state-of-the- art imaging techniques (e.g. two-photon scanning microscopy, single-plane illumination microscopy, spatial light modulator microscopy and lightfield microscopy), bioluminiscence and optogenetics to monitor and manipulate neuronal activity from single specific neurons up to the entire brain, in an intact behaving organism. Furthermore, the zebrafish model offers large and increasing collection of mutant and transgenic lines modelling human brain diseases. With these advantages in hand, the zebrafish larva became in the recent years, a novel animal model to study neuronal circuits and behaviour, taking us closer than ever before to understand how the brain controls behaviour.

Download or read book Neuronal Control of Locomotion written by Grigoriĭ Nikolaevich Orlovskiĭ and published by Oxford Neuroscience. This book was released on 1999 with total page 322 pages. Available in PDF, EPUB and Kindle. Book excerpt: What does the swimming leech have to do with the running human? The ability to move actively in space is essential to members of the animal kingdom, and the evolution of the nervous system relates to a large extent to the evolution of locomotion. The extreme importance of locomotion hasstimulated many studies of the neural mechanisms underlying locomotion across a range of species. For the first time, a group of three leading neurobiologists have undertaken a comparative study of these mechanisms. Neuronal Control of Locomotion: From Mollusc to Man describes how the brains invery diverse and evolutionarily removed species control the animal's locomotion. In doing so, the authors reveal unifying principles of brain function, making it essential reading for students and researchers in neurobiology generally, and motor control in particular. "In my opinion, the authorshave produced a masterful and highly readable exposition on the neural control of locomotion. It is timely and relevant to avant- garde neuroscience. It will have a major impact on the field, and is sure to be referenced well into the second half of the next century." Douglas Stuart, Universityof Arizona College of Medicine

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."
