This means that many neuroanatomists may balk at the functional interpretation I have given their sort of data, whereas many neuroscien tists in other fields may balk at references to neuroanatomy they cannot confirm from memory and begrudge the time to look up. Members of both groups may consequently decline to read the book on the ground that it is too risky or too difficult to follow, or both. Let me say, in my own defence, that although the argument presented here draws upon data from a number of different fields, they fit together in ways that are often quite striking; that the problem of memory is in itself an important one; and that theory in neuroscience, if it is to fulfill its function of unifying our understanding by way of testable propositions, has got, at some point, to become interdisciplinary. I submit that the present theory meets those requirements and may therefore justify the effort it asks of the reader. To the extent that it passes the critical test of experiment, it will also give research in the fields related to memory a clearer rationale, thereby, perhaps, saving time. Introduction What follows is an outline of the theory of memory functions developed in this monograph. It will not include the supporting data and references used throughout in the text, but will simply present the essentials of the argument.

This book presents a unique synthesis of the current neuroscience of cognition by one of the world's authorities in the field. The guiding principle to this synthesis is the tenet that the entirety of our knowledge is encoded by relations, and thus by connections, in neuronal networks of our cerebral cortex. Cognitive networks develop by experience on a base of widely dispersed modular cell assemblies representing elementary sensations and movements. As they develop cognitive networks organize themselves hierarchically by order of complexity or abstraction of their content. Because networks intersect profusely, sharing commong nodes, a neuronal assembly anywhere in the cortex can be part of many networks, and therefore many items of knowledge. All cognitive functions consist of neural transactions within and between cognitive networks. After reviewing the neurobiology and architecture of cortical networks (also named cognits), the author undertakes a systematic study of cortical dynamics in each of the major cognitive functions--perception, memory, attention, language, and intelligence. In this study, he makes use of a large body of evidence from a variety of methodologies, in the brain of the human as well as the nonhuman primate. The outcome of his interdisciplinary endeavor is the emergence of a structural and dynamic order in the cerebral cortex that, though still sketchy and fragmentary, mirrors with remarkable fidelity the order in the human mind.

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."

Neural memory remains largely a mystery despite all the attention it has received. Prompted by this observation, Joaquin M. Fuster presents the insights of more than three decades of empirical research on the neural processes by which memory is formed, stored and retrieved. This text focuses on the neocortex, where individual memory is deposited and represented, and offers a new taxonomy of memory that should accommodate the rapidly changing nature of the field and the various disciplines involved.

The prefrontal cortex is known to play important roles for performing a variety of higher cognitive functions. Among regions of the prefrontal cortex, the dorsolateral prefrontal cortex plays the most important roles for these functions. This book focuses on functions of the dorsolateral prefrontal cortex, summarizes research results obtained mainly by non-human primate studies, and describes neural mechanisms of executive functions that the dorsolateral prefrontal cortex participates. First, to understand the feature of the dorsolateral prefrontal cortex and how its function has been understood, anatomical and functional features of the dorsolateral prefrontal cortex and historical overview of prefrontal functions are described. To understand functions of the prefrontal cortex and neural mechanisms of executive functions, working memory is an important concept and sustained activation during the memory period of working memory tasks is known as a neural mechanism of working memory. Therefore, this book describes features of sustained memory-related activity based on neurophysiological results obtained in the prefrontal cortex and how memory-related activity contributes to executive functions including control of attention, inhibitory control, task management, and planning. And further, this book describes how the dorsolateral prefrontal cortex contributes to neural mechanisms for sensory and motor processing, memory control in multi-task performance, decision-making, metacognition, and top-down control. Thus, this book provides important information regarding neural mechanisms of dorsolateral prefrontal functions to neuroscientists and helps to plan further investigation to understand prefrontal functions in primates and human subjects.

The Evolution of Memory Systems sets out a bold and exciting new theory about memory. It proposes that several memory systems arose during evolution and that they did so for the same general reason: to transcend problems and exploit opportunities encountered by specific ancestors at particular times and places in the distant past.

The prefrontal cortex is particularly challenging as it has undergone great expansion during phylogenetic development and because it plays a crucial role in regulating most complex behaviors. Progress in research techniques in animals and in the development of non-invasive brain imaging approaches in humans have allowed resurgence of interest in the prefrontal cortex. To shed light on the rapidly accumulating information on motor and cognitive functions of the prefrontal cortex the Fondation IPSEN organized a symposium. This volume contains the proceedings of this meeting giving the most up-to-date research, with interdisciplinarycontributions from such fields as neuroanatomy, neuropharmacology, electrophysiology as well as from clinical and behavior studies. The contents of this book provides an important development in the understanding of the prefrontal cortex.

It is generally maintained that one of cortex' functions is the storage of a large number of memories. In this picture, the physical substrate of memories is thought to be realised in pattern and strengths of synaptic connections among cortical neurons. Memory recall is associated with neuronal activity that is shaped by this connectivity. In this framework, active memories are represented by attractors in the space of neural activity. Electrical activity in cortical neurones in vivo exhibits prominent temporal irregularity. A standard way to account for this phenomenon is to postulate that recurrent synaptic excitation and inhibition as well as external inputs are balanced. In the common view, however, these balanced networks do not easily support the coexistence of multiple attractors. This is problematic in view of memory function. Recently, theoretical studies showed that balanced networks with synapses that exhibit short-term plasticity (STP) are able to maintain multiple stable states. In order to investigate whether experimentally obtained synaptic parameters are consistent with model predictions, we developed a new methodology that is capable to quantify both response variability and STP at the same synapse in an integrated and statistically-principled way. This approach yields higher parameter precision than standard procedures and allows for the use of more efficient stimulation protocols. However, the findings with respect to STP parameters do not allow to make conclusive statements about the validity of synaptic theories of balanced working memory. In the second part of this thesis an alternative theory of cortical memory storage is developed. The theory is based on the assumptions that memories are stored in attractor networks, and that memories are not represented by network states differing in their average activity levels, but by micro-states sharing the same global statistics. Different memories differ with respect to their spatial distributions of firing rates. From this the main result is derived: the balanced state is a necessary condition for extensive memory storage. Furthermore, we analytically calculate memory storage capacities of rate neurone networks. Remarkably, it can be shown that crucial properties of neuronal activity and physiology that are consistent with experimental observations are directly predicted by the theory if optimal memory storage capacity is required.

The role of the prefrontal cortex is one of the most topical and important areas of research in contemporary neuropsychology. This cortical region appears to be linked with executive processes affecting many diverse areas of cognitive function. Working memory, information processing, behavioural organization, attention, judgement, and the ability to cope with novel experiences are just some of the diverse processes it affects. This book brings together contributions from some of the world's leading researchers on the prefrontal cortex. They discuss the many recent theoretical and technical advances in the field - for example in our understanding of the neural architecture of the prefrontal cortex, in the development of comparable texts of cognition in humans and other primates, in our understanding of the relationships between neuronal activity and behaviour, and in the increasing use of functional neuroimaging to identify different levels of organization within the prefrontal cortex. These important developments make this an ideal time to address the many questions and debates that have arisen about the role and functional organization of this area of the brain. One of the first books to be written on the subject, The Prefrontal Cortex is a state-of-the-art account of our knowledge of this exciting subject. It will be welcomed by all researchers and students in neuro- and cognitive psychology, and neuroscience.
