Trace


Book Description

With a New Preface by the Author Through personal journeys and historical inquiry, this PEN Literary Award finalist explores how America’s still unfolding history and ideas of “race” have marked its people and the land. Sand and stone are Earth’s fragmented memory. Each of us, too, is a landscape inscribed by memory and loss. One life–defining lesson Lauret Savoy learned as a young girl was this: the American land did not hate. As an educator and Earth historian, she has tracked the continent’s past from the relics of deep time; but the paths of ancestors toward her—paths of free and enslaved Africans, colonists from Europe, and peoples indigenous to this land—lie largely eroded and lost. A provocative and powerful mosaic that ranges across a continent and across time, from twisted terrain within the San Andreas Fault zone to a South Carolina plantation, from national parks to burial grounds, from “Indian Territory” and the U.S.–Mexico Border to the U.S. capital, Trace grapples with a searing national history to reveal the often unvoiced presence of the past. In distinctive and illuminating prose that is attentive to the rhythms of language and landscapes, she weaves together human stories of migration, silence, and displacement, as epic as the continent they survey, with uplifted mountains, braided streams, and eroded canyons. Gifted with this manifold vision, and graced by a scientific and lyrical diligence, she delves through fragmented histories—natural, personal, cultural—to find shadowy outlines of other stories of place in America. "Every landscape is an accumulation," reads one epigraph. "Life must be lived amidst that which was made before." Courageously and masterfully, Lauret Savoy does so in this beautiful book: she lives there, making sense of this land and its troubled past, reconciling what it means to inhabit terrains of memory—and to be one.

The Memory Trace (PLE: Memory)


Book Description

There was some agreement about what memory traces were not, but little about what actually did characterize the memory trace. Yet models and theories of memory at the time could not help making implicit and often unrecognized assumptions about the memory trace. Originally published in 1982, this title aimed to strengthen the meagre base on which memory theories rested at the time. It challenges old assumptions and introduces new concepts, foremost the notion of singularity, as they become necessary to understand traces adequately. Some research data of the past was found in need of reinterpretation. The result is a new theory of the memory trace.




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."




Memory, Amnesia, and the Hippocampal System


Book Description

In this sweeping synthesis, Neal J. Cohen and Howard Eichenbaum bring together converging findings from neuropsychology, neuroscience, and cognitive science that provide the critical clues and constraints for developing a more comprehensive understanding of memory. Specifically, they offer a cognitive neuroscience theory of memory that accounts for the nature of memory impairment exhibited in human amnesia and animal models of amnesia, that specifies the functional role played by the hippocampal system in memory, and that provides further understanding of the componential structure of memory.The authors' central thesis is that the hippocampal system mediates a capacity for declarative memory, the kind of memory that in humans supports conscious recollection and the explicit and flexible expression of memories. They argue that this capacity emerges from a representation of critical relations among items in memory, and that such a relational representation supports the ability to make inferences and generalizations from memory, and to manipulate and flexibly express memory in countless ways. In articulating such a description of the fundamental nature of declarative representation and of the mnemonic capabilities to which it gives rise, the authors' theory constitutes a major extension and elaboration of the earlier procedural-declarative account of memory.Support for this view is taken from a variety of experimental studies of amnesia in humans, nonhuman primates, and rodents. Additional support is drawn from observations concerning the neuroanatomy and neurophysiology of the hippocampal system. The data taken from divergent literatures are shown to converge on the central theme of hippocampal involvement in declarative memory across species and across behavioral paradigms.

Memory Makes the Brain


Book Description

The development of the young brain after birth and the emergence of cognitive capacities, mind, and individuality rest on the maturation of a dense net of synaptic connections between neurons. Memory Makes the Brain describes the dramatic, competitive elimination of surplus synapses that occur in the young, maturing brain -- in a process called synaptic pruning that was discovered by pediatric neurologist Peter Huttenlocher in the 1970's at the University of Chicago. Explaining similarities between developmental pruning and learning processes in the adult brain, neurobiologist Christian Hansel offers a unique perspective on brain adaptation and plasticity throughout lifetime, at times weaving in personal accounts and memories. The cellular plasticity machinery that enables learning is known to be affected in brain developmental disorders such as autism. Memory Makes the Brain explains how both maturation and adult synaptic plasticity are deregulated in autism, and how we begin to trace back autism-typical behavioral abnormalities to such synaptopathies.




Temporal Coding in the Brain


Book Description

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.




Modeling Human and Organizational Behavior
