Category : Medical
Languages : en
Pages : 296

Book Description
The distributed coding hypothesis —the view that complex cognitive functions such as visual perception or memory formation are the work of large networks of neurons in areas of the cerebral cortex —is widely accepted in contemporary neuroscience. Yet only in recent years have tools emerged that can monitor the electrophysiological activity of neuron ensembles in the cortical areas of awake, behaving animals. The use of these multichannel recording techniques in biological network analysis is changing the way scientists view brain function. These methods also offer the possibility of a direct test of the distributed coding hypothesis. Neuronal Ensembles: Strategies for Recording and Decoding presents a comprehensive treatment of multichannel recording techniques —how to apply them and how to analyze the vast amounts of data they generate. Composed of contributions by leading neuroscientists at the forefront of this technology, the book covers groundbreaking work in multichannel microelectrode technology, analyses of single neuron spike trains, and ensemble analysis of cell populations. The authors outline established techniques, offer practical tips on developing new methods, and share their ideas for further brain research. Topics covered include: Extracellular recording and analysis of neural activity The relationship between neuronal codes and cortical organization Cell assemblies and cognitive function Neuronal population coding Motor cortical information processing Detection and identification of ensemble codes in the motor cortex Ensemble recordings and the nature of stimulus representation in hippocampal cognitive maps Methods, results, and issues related to recording neural ensembles Neuronal ensemble dynamics in the hippocampus and neocortex during sleep and waking Behavioral, electrophysiological, and genetic approaches to the study of synaptic plasticity and memory Neuronal Ensembles: Strategies for Recording and Decoding is an important reference for researchers, graduate students, and postdoctoral fellows in all areas of neuroscience, cognitive neuroscience, and bioengineering.

Book Description
Neuronal cells (neurons) mainly transmit signals by action potentials or spikes.Neuronal electrical activity is recorded from experimental animals bymicroelectrodesplaced in specific brain areas. These electrochemical fast phenomenaoccur as all-or-none events and can be analyzed as boolean sequences. Followingthis approach, several computational analyses reported most variable neuronalbehaviors expressed through a large variety of firing patterns [13]. Thesepatternshave been modeled as symbolic strings with a number of different techniques[23, 55]The results obtained with these methods come (i) from Ventrobasal ThalamicNuclei (VB) and Somatosensory Cortex (SSI) in Chronic Pain Animals (CPAs), (ii) from Primary Visual (V1) and (SSI) in rat Cortices and, finally, (iii) fromIL human Thalamus Nuclei in patients suffering from states of disorderedconsciousnesslike Persistent Vegetative State (PVS) and Minimum Conscious State(MCS).

Metastable Dynamics of Neural Ensembles

Metastable Dynamics of Neural Ensembles PDF Author: Emili Balaguer-Ballester
Publisher: Frontiers Media SA
ISBN: 2889454371
Category :
Languages : en
Pages : 152

Book Description
A classical view of neural computation is that it can be characterized in terms of convergence to attractor states or sequential transitions among states in a noisy background. After over three decades, is this still a valid model of how brain dynamics implements cognition? This book provides a comprehensive collection of recent theoretical and experimental contributions addressing the question of stable versus transient neural population dynamics from complementary angles. These studies showcase recent efforts for designing a framework that encompasses the multiple facets of metastability in neural responses, one of the most exciting topics currently in systems and computational neuroscience.

The Relevance of the Time Domain to Neural Network Models

The Relevance of the Time Domain to Neural Network Models PDF Author: A. Ravishankar Rao
Publisher: Springer Science & Business Media
ISBN: 1461407249
Category : Medical
Languages : en
Pages : 234

Book Description
A significant amount of effort in neural modeling is directed towards understanding the representation of information in various parts of the brain, such as cortical maps [6], and the paths along which sensory information is processed. Though the time domain is integral an integral aspect of the functioning of biological systems, it has proven very challenging to incorporate the time domain effectively in neural network models. A promising path that is being explored is to study the importance of synchronization in biological systems. Synchronization plays a critical role in the interactions between neurons in the brain, giving rise to perceptual phenomena, and explaining multiple effects such as visual contour integration, and the separation of superposed inputs. The purpose of this book is to provide a unified view of how the time domain can be effectively employed in neural network models. A first direction to consider is to deploy oscillators that model temporal firing patterns of a neuron or a group of neurons. There is a growing body of research on the use of oscillatory neural networks, and their ability to synchronize under the right conditions. Such networks of synchronizing elements have been shown to be effective in image processing and segmentation tasks, and also in solving the binding problem, which is of great significance in the field of neuroscience. The oscillatory neural models can be employed at multiple scales of abstraction, ranging from individual neurons, to groups of neurons using Wilson-Cowan modeling techniques and eventually to the behavior of entire brain regions as revealed in oscillations observed in EEG recordings. A second interesting direction to consider is to understand the effect of different neural network topologies on their ability to create the desired synchronization. A third direction of interest is the extraction of temporal signaling patterns from brain imaging data such as EEG and fMRI. Hence this Special Session is of emerging interest in the brain sciences, as imaging techniques are able to resolve sufficient temporal detail to provide an insight into how the time domain is deployed in cognitive function. The following broad topics will be covered in the book: Synchronization, phase-locking behavior, image processing, image segmentation, temporal pattern analysis, EEG analysis, fMRI analyis, network topology and synchronizability, cortical interactions involving synchronization, and oscillatory neural networks. This book will benefit readers interested in the topics of computational neuroscience, applying neural network models to understand brain function, extracting temporal information from brain imaging data, and emerging techniques for image segmentation using oscillatory networks
