Understanding brain functions, especially the neural mechanisms of higher cognitive processes such as thinking, reasoning, judging, and decision making, are the subjects covered by the chapters of this book. They describe recent progress in four major research areas: visual functions, motor functions, memory functions, and prefrontal functions. There are many color illustrations making this book an especially valuable resource for students and researchers in neuroscience.
Cognitive processing is commonly conceptualized as being restricted to the cerebral cortex. Accordingly, electrophysiology, neuroimaging and lesion studies involving human and animal subjects have almost exclusively focused on defining roles for cerebral cortical areas in cognition. Roles for the thalamus in cognition have been largely ignored despite the fact that the extensive connectivity between the thalamus and cerebral cortex gives rise to a closely coupled thalamo-cortical system. However, in recent years, growing interest in the thalamus as much more than a passive sensory structure, as well as methodological advances such as high-resolution functional magnetic resonance imaging of t...
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...
We have politics on our mind—or, rather, we have politics in different parts of our brains. In this path-breaking study, Matt Qvortrup takes the reader on a whistle stop tour through the fascinating, and sometimes frightening, world of neuropolitics; the discipline that combines neuroscience and politics, and is even being used to win elections. Putting the 'science' back into political science, The Political Brain shows how fMRI-scans can identify differences between Liberals and Conservatives, can predict our behaviour with sometimes greater accuracy than surveys, and can explain the biology of uprisings, revolutions, and wars. Not merely a study of empirical evidence, the book shows how the philosophical theories of, among others, Plato, Aristotle, and Spinoza can be supported by brain scans. Along the way, it also provides an overview of the state-of-the-art knowledge of the organ that shapes our politics. The book shows that if we rely on evolutionary primitive parts of the midbrain—those engaged when we succumb to polarised politics—we stand in danger of squandering the gains we made through the last eight million years.
Visual working memory allows us to temporarily maintain and manipulate visual information in order to solve a task. The study of the brain mechanisms underlying this function began more than a half century ago, with Scoville and Milner’s (1957) seminal discoveries with amnesic patients. This timely collection of papers brings together diverse perspectives on the cognitive neuroscience of visual working memory from multiple fields that have traditionally been fairly disjointed: human neuroimaging, electrophysiological, behavioural and animal lesion studies, investigating both the developing and the adult brain.
This exciting volume brings together the latest work of 26 recognized experts in clinical neuropsychiatry, neuropsychology, neuroscience, and neuroimaging. Its chapters are organized into sections that cover a broad range of topics related to advances in our understanding of normal and abnormal frontal lobe functions. Part 1 introduces frontal lobe dysfunction as a common pathway leading to social and occupational disability, arguing that our aging population with its decline in executive cognitive abilities mandates corresponding eligibility and treatment changes in public and private health disability policies. Part 2 delineates the anatomy and neurochemistry of the extended frontal system...
This book constitutes, together with its compagnion LNCS 1606, the refereed proceedings of the International Work-Conference on Artificial & Neural Networks, IWANN'99, held in Alicante, Spain in June 1999. The 91 revised papers presented were carefully reviewed & selected for inclusion in the book. This volume is devoted to applications of biologically inspired artificial neural networks in various engineering disciplines. The papers are organized in parts on artificial neural nets simulation & implementation, image processing & engineering applications.
Sometimes, memories are like feathers that can fly into our cerebral labyrinths, taking a ship for sail, crossing neural networks like the flow of ethereal butterflies. In other situations, our remembrances are settled down like deep roots of strong trees.This book introduces also an experimental protocol, about conceptual neurons and how these nerve cells can identify emotional insights when they discriminate an iconic sample (a famous human image, well spread all over the world).Finally, analyzing the Working Memory Paradigm, this text describes new neuronal networks participating in neuronal processing like mental representations in predictive tasks associated to prefrontal cortex.
This volume, Prefrontal Cortex: from Synaptic Plasticity to Cognition, is an interdisciplinary approach to characterize the function of the anterior portion of the frontal lobe in rodents and human and non-human primates. The specific topics discussed in the chapters of this volume are purposefully diverse: they range from membrane properties of prefrontal neurons to cognitive psychology. Nevertheless, this volume must not be regarded as a mere collection of writings with the different sub-themes. As you will see, chapters often vigorously encompass domains of the prefrontal field in effort to provide a big picture. That is actually what we attempted to do in this volume. On one hand, we hav...
