This book was released on 2011 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The electrophysiological correlates of recognition memory retrieval were examined in order to identify the neural conditions that precede accurate memory retrieval, characterize the processes that contribute to high and low confidence memory responses, and determine which memory processes are impaired after brain injury. Human electroencephalogram (EEG) was recorded during recognition confidence and source memory judgments in three experiments. In Experiment 1, mid-frontal pre-stimulus theta oscillations were found to precede the stimulus presentation of items that were successfully recollected, but they were not found to be predictive of item familiarity. Moreover, during stimulus presentation, recollection was associated with an increase in theta over left parietal regions, and the magnitude of this effect was predicted by the earlier per-stimulus theta effects. The results suggest that pre-stimulus processes set the stage for and facilitate subsequent recollection. In experiment 2, high and low confidence source memory judgments were found to be supported by two electrophysiologically distinct processes. Whereas correct high confidence source memory was associated with a late positive component indicative of recollection, correct low confidence source memory was associated with a late onset negative going ERP that was distinct from both recollection and familiarity based responses. The results indicate that correct source memory responses can be observed even in the absence of recollection. In experiment 3, ERPs were recorded in amnesics in order to determine whether they exhibited selective deficits in recollection, as previous behavioral studies had suggested. Behavioral data showing relatively preserved item recognition along with severely impaired source recollection was consistent with prior studies of these patients, and ERPs revealed that the patients showed no evidence of recollection-related neurophysiology, but maintained normal ERP correlates of familiarity. These results indicate that these patients exhibit selective recollection deficits, are consistent with dual process models of memory, and suggest that source memory depends critically upon the medial temporal lobe structures, such as the hippocampus, which are typically disrupted in amnesia.
Download or read book Memory Organization and Locus of Change written by Larry R. Squire and published by Oxford University Press. This book was released on 1992-03-19 with total page 438 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book brings together an internationally respected group of researchers for the purpose of examining neuroplasticity, a topic of immense current interest in psychology, neuroscience, neuropsychology, and clinical neurology. The chapters represent state-of-the-art work on neuroplasticity at all levels: behavioral, neural, and molecular. They describe recent work on memory ranging from cellular morphological studies in invertebrates to research on the human brain made possible by new advances in neuroimaging technology. The book begins with an introductory chapter that considers the psychology of memory at the global, structural level. The remainder of the volume is divided into three related parts. The first focuses on recent approaches, which are based in part on new technology, that aim to measure and describe activity in relatively large populations of neurons. The second focuses on memory at the level of brain systems. One major theme to emerge from work at this level is that memory is composed of multiple, separable components that can be identified with specific anatomical structures and connections. The third part of the book focuses on molecular and cellular studies that show how individual neurons and their synapses behave in a history-dependent manner. This research concerns both brief changes in synaptic plasticity as well as more lasting changes in connectivity, which depend on altered gene expression and morphological growth and change. Altogether, the chapters provide a rich summary of the breadth and excitement of contemporary research on the biology of memory.

Available in PDF, EPUB and Kindle. Book excerpt: Recent advances in techniques available to memory researchers have led to a rapid expansion in the field of cognitive neuroscience of memory. This book provides accessible coverage of four key areas of recent advance, including research on functional imaging, electrophysiological and lesion studies, and developments from the computational modelling approach. The first section reviews functional imaging studies in humans, with particular emphasis on how imaging methods have clarified the cortical areas involved in memory formation and retrieval. The second section describes electrophysiological and lesion research in monkeys, where lesion and disconnection studies are rapidly adding to our knowledge of both information processing and modulatory aspects of memory formation. In the third section, electrophysiological and lesion studies in rats are reviewed allowing for a detailed study of the role of novelty and exploration in memory formation. The final section reviews current research in computational modelling which has allowed the development of new theoretical and experimental approaches to the study of memory encoding and retrieval. This volume draws together the current developments in each field, allowing the synthesis of ideas and providing converging evidence from a range of sources. It will be a useful resource for both advanced undergraduate and postgraduate students of psychology, as well as researchers in the field and anyone with an interest in cognitive neuroscience.
Download or read book Neuropsychological Impairments of Short Term Memory written by Giuseppe Vallar and published by Cambridge University Press. This book was released on 2007-09-21 with total page 540 pages. Available in PDF, EPUB and Kindle. Book excerpt: This work summarizes the current state of empirical and theoretical work on impairments of short-term memory (often caused by damage in the left cerebral hemisphere) and contains chapters from virtually every scientist in Europe and North America working on the problem. The chapters present evidence from both normal and brain-damaged patients, providing a comprehensive view of the functional characteristics of auditory-verbal short-term memory and its neurobiological correlates. Two neuropsychological issues are discussed in detail: the specific patterns of immediate memory impairment resulting from brain damage, with reference to both multi-store and the interactive-activation theoretical frameworks, and the relation between verbal STM and sentence comprehension disorders in patients with a defective immediate auditory memory, an area of major controversy in recent years.
Download or read book Synaptic Modifications and Memory written by Leon L. Voronin and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 315 pages. Available in PDF, EPUB and Kindle. Book excerpt: Understanding of memory and learning is one of the major goals of neuroscientists and psychologists. The author first introduces the reader into the current state of knowledge of the mechanisms underlying memory by providing extensive reviews of contemporary results including behavioural approaches and molecular studies. He presents results of his group obtained by analysing elec- trical activity - including single neuron meassures. As a major experimental model the phenomenon of hippocampal long- term potentiation was studied. The so-called quantal analy- sis - a quantitative method - was applied to study mammalian brain plasticity. Short- and long-term synaptic plasticities were registered both in vivo and in vitro mammalian brain preparations. Results show the involvement of mainly presynaptic location in memory, however, the possible involvement of postsynaptic mechanisms is indicated by changes in quantal amplitude as shown by the author.

Download or read book Neuronal Mechanisms of Memory Formation written by Christian Hölscher and published by Cambridge University Press. This book was released on 2001 with total page 509 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
