Associative Memory Cells Basic Units Of Memory Trace

This book focuses on associative memory cells and their working principles, which can be applied to associative memories and memory-relevant cognitions. Providing comprehensive diagrams, it presents the author's personal perspectives on pathology and therapeutic strategies for memory deficits in patients suffering from neurological diseases and psychiatric disorders. Associative learning is a common approach to acquire multiple associated signals, including knowledge, experiences and skills from natural environments or social interaction. The identification of the cellular and molecular mechanisms underlying associative memory is important in furthering our understanding of the principles of memory formation and memory-relevant behaviors as well as in developing therapeutic strategies that enhance memory capacity in healthy individuals and improve memory deficit in patients suffering from neurological disease and psychiatric disorders. Although a series of hypotheses about neural substrates for associative memory has been proposed, numerous questions still need to be addressed, especially the basic units and their working principle in engrams and circuits specific for various memory patterns. This book summarizes the developments concerning associative memory cells reported in current and past literature, providing a valuable overview of the field for neuroscientists, psychologists and students.

Providing the first glimpse of how associative memories are actually established in our brains, this book describes a research strategy for unravelling the mystery of memory and learning. The results of this experimental quest are described at several levels of biological complexity including animal behavior, neural systems, cellular and membrane physiology, and molecular regulation. The amply illustrated text is carefully structured to distinguish between observations and hypotheses, between attractive possibilities and empirical demonstrations. Dr Alkon progresses step-by-step through a series of experimental tests of intuitive conjectures on the nature of learning and memory. The book guides the reader through a scientific detective story that sheds new light on how we learn and how we remember.

Published in 1980, part of the Experimental Psychology series. This book proposes and tests a theory about human memory, about how a person encodes, retains, and retrieves information from memory. This edition contains two major parts. First is the historical analysis of associationism and its countertraditions. This still provides the framework that has been used to relate the current research to an important intellectual tradition. This is reproduced without comment from the original book; historical analyses do not need as rapid revision as theoretical analyses. The second part of the book reproduces the major components of the HAM theory.

This book contains two types of material first, the many divergent and often diffuse meanings given to the concepts of association, associative memory, and associative recall are expounded. A review of this kind was felt necessary because there apparently does not exist any single monograph which could serve as a reference to these topics. But the presentation of the main body of this text is motivated by quite other reasons: in recent years, plenty of interesting mathematical and system-theoretical material has been published which makes it possible to gain a view of associative memory which is different from the conventional abstract and computationally oriented approaches. It seems that the basic operation of associative memory, the storage of information together with the relations or links between the data items, and the selective recall of stored information relative to a piece of key or cue information presented, is not restricted to certain computer-technological implementations but can also be reflected in more general mathematically describable processes in certain physical or other systems, especially in their adaptive state changes. It further seems that some generally known forms of associative memory, namely, certain computer technological artifacts, or abstract systems of concepts or data, are in fact special representations of a class of processes characterized as associative memory.

The hippocampus is a bicortical structure with extensive fiber connections with multiple brain regions. It is involved in several functions, such as learning, memory, attention, emotion, and more. This book covers various aspects of the hippocampus including cytoarchitecture, functions, diseases, and treatment. It highlights the most advanced findings in research on the hippocampus. It discusses circuits, pattern formation process of grid cells, and zinc dynamics of the hippocampus. The book also addresses the tau pathology and circRNAs related to Alzheimer’s disease and potential treatment strategies. It is a useful resource for general readers, students, and researchers.

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."

Learning and Memory: A Biological View is a comprehensive textbook about the neurobiology of learning and memory. Topics covered include developmental approaches to the memory process; anatomical correlates of neuronal plasticity; drugs that modulate learning and memory; and biochemical correlates of learning and memory. The link between aging and memory is also discussed, along with electrophysiological approaches to the study of memory. Comprised of 12 chapters, this book begins with a review of historical traditions that influenced research on the biological basis of learning and memory. Experimental findings suggesting that the engram for a simple classically conditioned skeletal response may be in the cerebellum are also presented. The next chapter emphasizes the importance of anatomical mechanisms that could mediate learning, plasticity, and memory storage in young and adult animals. Subsequent chapters explore the influence of peripheral hormones and particularly opioid peptides on complex behavior such as learning and memory; the contribution of individual neurotransmitter systems to learning; the psychopathology of aging; and long-term potentiation as a model of the way the central nervous system stores information. Learning in complex vertebrate systems and direct stimulation of various brain nuclei are also examined. The final chapter presents a neurobehavioral analysis of the structure of memory formation that utilizes lesions and explores human memory pathology. This monograph is intended for advanced undergraduate students, graduate students, and research workers in the field of memory.
