Novel Mechanisms of Memory


Book Description

This book integrates discoveries from recent years to show the diversity of molecular mechanisms that contribute to memory consolidation, reconsolidation, extinction, and forgetting. It provides a special focus on the processes that govern functional and structural plasticity of dendritic spines. In nine chapters, new and important ideas related to learning and memory processes will be presented. Themes discussed include the role of AMPA receptors in memory, two signalling cascades involved in local spine remodelling and memory, the role of extracellular matrix proteins in memory, the regulation of gene expression and protein translation, and mechanisms of retrieval-induced memory modulation and forgetting. We believe that the study of these topics represents a great step toward understanding the complexity of the brain and the processes it governs.




Neuronal Mechanisms of Memory Formation


Book Description

Long-term potentiation (LTP) is by far the most dominant model for neuronal changes that might encode memory. LTP is an elegant concept that meets many criteria set up by theoreticians long before the model's discovery, and it also fits anatomical data of learning-dependent synapse changes. Since the discovery of LTP, the question has remained about how closely LTP produced in vitro by artificial stimulation of neurons actually models putative learning-induced synaptic changes. A number of recent investigations have tried to correlate synaptic changes observed after learning with changes produced by artificial stimulation of neurons. These studies have failed to find a correlation between the two forms of synaptic plasticity. In this book, an international group of neurobiologists and psychologists discuss their latest ideas and data. The results of experiments using electrophysiological techniques in vitro are discussed and compared with the results of in vivo experiments. Learning experiments are also discussed. Theoretical models such as the Hebb theory of synaptic changes during learning are compared to different models that do not predict upregulation of synaptic transmission. A wide approach is taken, and research and models in different brain areas such as the neocortex and the basal brain are discussed.




Mechanisms of Sensory Working Memory


Book Description

Mechanisms of Sensory Working Memory: Attention and Performance XXV provides an update on research surrounding the memory processes that are crucial for many facets of cognitive processing and experience, with new coverage of emerging areas of study, including a new understanding of working memory for features of stimuli devoid of verbal, phonological, or long-term memory content, such as memory for simple visual features (e.g., texture or color), simple auditory features (e.g., pitch), or simple tactile features (e.g., vibration frequency), now called sensory memory to distinguish from verbal memory. This contemporary focus on sensory memory is just beginning, and this collection of original contributions provides a foundational reference for the study mechanisms of sensory memory. Students, scholars, and researchers studying memory mechanisms and processes in cognitive neuroscience, cognitive science, neuroscience, and psychology will find this book of great value to their work. - Introduces the study of sensory mechanisms of working memory as distinct from verbal memory - Covers visual memory, auditory memory, and tactile memory - Includes translational content as the breakdown of working memory is often associated with a disease, disorder, or trauma to the brain

Discovering the Brain


Book Description

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."




The Memory Thief


Book Description

FINALIST FOR THE 2022 PEN/E.O. WILSON LITERARY SCIENCE WRITING AWARD "Aguirre writes clearly, concisely, and often cinematically. The book succeeds in providing an accessible yet substantive look at memory science and offering glimpses of the often-challenging process of biomedical investigation.”—Science Sometimes, it’s not the discovery that’s hard – it’s convincing others that you’re right. The Memory Thief chronicles an investigation into a rare and devastating amnesia first identified in a cluster of fentanyl overdose survivors. When a handful of doctors embark on a quest to find out exactly what happened to these marginalized victims, they encounter indifference and skepticism from the medical establishment. But after many blind alleys and occasional strokes of good luck, they go on to prove that opioids can damage the hippocampus, a tiny brain region responsible for forming new memories. This discovery may have implications for millions of people around the world. Through the prism of this fascinating story, Aguirre recounts the obstacles researchers so often confront when new ideas bump up against conventional wisdom. She explains the elegant tricks scientists use to tease out the fundamental mechanisms of memory. And finally, she reveals why researchers now believe that a treatment for Alzheimer’s is within reach.




From Conditioning to Conscious Recollection


Book Description

This cutting-edge book offers a theoretical account of the evolution of multiple memory systems of the brain. The authors conceptualize these memory systems from both behavioral and neurobiological perspectives, guided by three related principles. First, that our understanding of a wide range of memory phenomena can be advanced by breaking down memory into multiple forms with different operating characteristics. Second, that different forms of memory representation are supported by distinct brain pathways with circuitry and neural coding properties. Third, that the contributions of different brain systems can be compared and contrasted by distinguishing between dedicated (or specific) and elaborate (or general) memory systems. A primary goal of this work is to relate the neurobiological properties of dedicated and elaborate systems to their neuropsychological counterparts, and in so doing, account for the phenomenology of memory, from conditioning to conscious recollection.
