Available in PDF, EPUB and Kindle. Book excerpt: Given two events, both of which are well remembered, can we specify which event occurred first? If so, how? For example, did Nixon resign, before or after Billie Jean King beat Bobby Riggs? Originally published in 1977, little was known about the accuracy of temporal codes for memories, and still less about the nature of the codes. This volume addresses the central question of the mechanisms by which order information is attached to memories. The results of sixteen previously unpublished experiments indicate the role of some independent variables on temporal coding in relatively short-term memory and in long-term memory. Several experiments, in which changes in proactive inhibition are used as an index of temporal differentiation, show that the nature of the words making up the lists is involved fundamentally in temporal coding. Other experiments demonstrate that in relatively short-term memory a subject cannot learn to improve his performance in estimating how far apart in time two events occurred. Still other experiments show that recency judgments for two events improve with practice, but the improvement is independent of the temporal separation. The context in which memories are established is shown to influence temporal codes only if an ordering metric is part of the context. The author advances several theoretical propositions to account for the various findings. In doing so he has given initial structuring for subsequent research to a neglected area. This volume will still be of significant interest to all those interested in learning and memory.

Available in PDF, EPUB and Kindle. Book excerpt: Temporal coding in the brain documents a revolution now occurring in the neurosciences. How does parallel processing of information bind together the complex nature of the outer and our inner worlds? Do intrinsic oscillations and transient cooperative states of neurons represent the physiological basis of cognitive and motor functions of the brain? Some answers to these challenging issues are provided in this book by leading world experts of brain function. A common denominator of the works presented in this volume is the nature and mechanisms of neuronal cooperation in the temporal domain. The topics range from simple organisms to the human brain. The volume is intended for investigators and graduate students in neurophysiology, cognitive neuroscience, neural computation and neurology.
Download or read book The Neurobiological Basis of Memory written by Pamela A. Jackson and published by Springer. This book was released on 2015-09-19 with total page 428 pages. Available in PDF, EPUB and Kindle. Book excerpt: This exciting volume offers an up-to-date tour of current trends in the neurobiology of memory while saluting Raymond Kesner's pioneering contributions to the field as a theorist and researcher, teacher and mentor. Starting with his signature chapter introducing the Attribute Model of Memory, the first half of the book focuses on the central role of the hippocampus in processing dimensions of space and time, and branches out to memory system interactions across brain structures. Later chapters apply the attribute model to multiple functions of memory in learning, and to specific neurological contexts, including Huntington's disease, traumatic brain injury, and Fragile X. As a bonus, the book concludes with an essay on Kesner's life and work, and reminiscences by colleagues. Among the topics covered: How the hippocampus supports the spatial and temporal attributes of memory. Self-regulation of memory processing centers of the brain. Multiple memory systems: the role of Kesner's Attribute Model in understanding the neurobiology of memory. Pattern separation: a key processing deficit associated with aging? · Prefrontal cortex and basal ganglia attributes underlying behavioral flexibility. Memory disruption following traumatic brain injury. Cognitive neuroscientists, neuropsychologists, gerontologists, psychiatrists, and neurobiologists will find The Neurobiological Basis of Memory both enlightening and inspiring--much like Kesner himself.

Download or read book The Role of Synaptic Tagging and Capture for Memory Dynamics in Spiking Neural Networks written by Jannik Luboeinski and published by . This book was released on 2021-09-02 with total page 201 pages. Available in PDF, EPUB and Kindle. Book excerpt: Memory serves to process and store information about experiences such that this information can be used in future situations. The transfer from transient storage into long-term memory, which retains information for hours, days, and even years, is called consolidation. In brains, information is primarily stored via alteration of synapses, so-called synaptic plasticity. While these changes are at first in a transient early phase, they can be transferred to a late phase, meaning that they become stabilized over the course of several hours. This stabilization has been explained by so-called synaptic tagging and capture (STC) mechanisms. To store and recall memory representations, emergent dynamics arise from the synaptic structure of recurrent networks of neurons. This happens through so-called cell assemblies, which feature particularly strong synapses. It has been proposed that the stabilization of such cell assemblies by STC corresponds to so-called synaptic consolidation, which is observed in humans and other animals in the first hours after acquiring a new memory. The exact connection between the physiological mechanisms of STC and memory consolidation remains, however, unclear. It is equally unknown which influence STC mechanisms exert on further cognitive functions that guide behavior. On timescales of minutes to hours (that means, the timescales of STC) such functions include memory improvement, modification of memories, interference and enhancement of similar memories, and transient priming of certain memories. Thus, diverse memory dynamics may be linked to STC, which can be investigated by employing theoretical methods based on experimental data from the neuronal and the behavioral level. In this thesis, we present a theoretical model of STC-based memory consolidation in recurrent networks of spiking neurons, which are particularly suited to reproduce biologically realistic dynamics. Furthermore, we combine the STC mechanisms with calcium dynamics, which have been found to guide the major processes of early-phase synaptic plasticity in vivo. In three included research articles as well as additional sections, we develop this model and investigate how it can account for a variety of behavioral effects. We find that the model enables the robust implementation of the cognitive memory functions mentioned above. The main steps to this are: 1. demonstrating the formation, consolidation, and improvement of memories represented by cell assemblies, 2. showing that neuromodulator-dependent STC can retroactively control whether information is stored in a temporal or rate-based neural code, and 3. examining interaction of multiple cell assemblies with transient and attractor dynamics in different organizational paradigms. In summary, we demonstrate several ways by which STC controls the late-phase synaptic structure of cell assemblies. Linking these structures to functional dynamics, we show that our STC-based model implements functionality that can be related to long-term memory. Thereby, we provide a basis for the mechanistic explanation of various neuropsychological effects. Keywords: synaptic plasticity; synaptic tagging and capture; spiking recurrent neural networks; memory consolidation; long-term memory
Download or read book Discovering the Brain written by National Academy of Sciences and published by National Academies Press. This book was released on 1992-01-01 with total page 195 pages. Available in PDF, EPUB and Kindle. Book excerpt: The brain ... There is no other part of the human anatomy that is so intriguing. How does it develop and function and why does it sometimes, tragically, degenerate? The answers are complex. In Discovering the Brain, science writer Sandra Ackerman cuts through the complexity to bring this vital topic to the public. The 1990s were declared the "Decade of the Brain" by former President Bush, and the neuroscience community responded with a host of new investigations and conferences. Discovering the Brain is based on the Institute of Medicine conference, Decade of the Brain: Frontiers in Neuroscience and Brain Research. Discovering the Brain is a "field guide" to the brainâ€"an easy-to-read discussion of the brain's physical structure and where functions such as language and music appreciation lie. Ackerman examines: How electrical and chemical signals are conveyed in the brain. The mechanisms by which we see, hear, think, and pay attentionâ€"and how a "gut feeling" actually originates in the brain. Learning and memory retention, including parallels to computer memory and what they might tell us about our own mental capacity. Development of the brain throughout the life span, with a look at the aging brain. Ackerman provides an enlightening chapter on the connection between the brain's physical condition and various mental disorders and notes what progress can realistically be made toward the prevention and treatment of stroke and other ailments. Finally, she explores the potential for major advances during the "Decade of the Brain," with a look at medical imaging techniquesâ€"what various technologies can and cannot tell usâ€"and how the public and private sectors can contribute to continued advances in neuroscience. This highly readable volume will provide the public and policymakersâ€"and many scientists as wellâ€"with a helpful guide to understanding the many discoveries that are sure to be announced throughout the "Decade of the Brain."

Download or read book Memory and Cognition in Its Social Context written by Robert S. Wyer, Jr. and published by Psychology Press. This book was released on 2014-02-04 with total page 504 pages. Available in PDF, EPUB and Kindle. Book excerpt: The first comprehensive theoretical formulation of the way people use information they receive about their social environments to make judgments and behavioral decisions, this volume focuses on the cognitive processes that underlie the use of social information. These include initial interpretation, the representations used to make inferences, and the transformation of these subjective inferences into overt judgment and behavior. In addition, it specifies the role of affect and emotion in information processing, and the role of self-knowledge at different stages of processing. The theoretical model presented here is the first to provide a conceptual integration of existing theory and research in all phases of social information processing. It not only accounts for the major portion of existing research findings, but permits several hypotheses to be generated concerning phenomena that have not yet been empirically investigated. Although focused here on the processing of information about people and events, the formulation proposed has implications for other domains such as personnel appraisal, political decision making, and consumer behavior.
