Over the last two decades, the recognition that astrocytes - the predominant type of cortical glial cells - could sense neighboring neuronal activity and release neuroactive agents, has been instrumental in the uncovering of many roles that these cells could play in brain processing and the storage of information. These findings initiated a conceptual revolution that leads to rethinking how brain communication works since they imply that information travels and is processed not just in the neuronal circuitry but in an expanded neuron-glial network. On the other hand the physiological need for astrocyte signaling in brain information processing and the modes of action of these cells in computational tasks remain largely undefined. This is due, to a large extent, both to the lack of conclusive experimental evidence, and to a substantial lack of a theoretical framework to address modeling and characterization of the many possible astrocyte functions. This book that we propose aims at filling this gap, providing the first systematic computational approach to the complex, wide subject of neuron-glia interactions. The organization of the book is unique insofar as it considers a selection of "hot topics" in glia research that ideally brings together both the novelty of the recent experimental findings in the field and the modelling challenge that they bear. A chapter written by experimentalists, possibly in collaboration with theoreticians, will introduce each topic. The aim of this chapter, that we foresee less technical in its style than in conventional reviews, will be to provide a review as clear as possible, of what is "established" and what remains speculative (i.e. the open questions). Each topic will then be presented in its possible different aspects, by 2-3 chapters by theoreticians. These chapters will be edited in order to provide a "priming" reference for modeling neuron-glia interactions, suitable both for the graduate student and the professional researcher.
This book proposes a novel CWW model to personalize individual semantics in linguistic decision making, based on two new concepts: numerical scale and consistency-driven methodology. The numerical scale model provides a unified framework to connect different linguistic symbolic computational models for CWW, and the consistency-driven methodology customizes individuals' semantics to support linguistic group decision making by setting personalized numerical scales. The book is a valuable resource for researchers and postgraduates who are interested in CWW in linguistic decision making.
GABA is the principal inhibitory neurotransmitter in the CNS and acts via GABAA and GABAB receptors. Recently, a novel form of GABAA receptor-mediated inhibition, termed "tonic" inhibition, has been described. Whereas synaptic GABAA receptors underlie classical "phasic" GABAA receptor-mediated inhibition (inhibitory postsynaptic currents), tonic GABAA receptor-mediated inhibition results from the activation of extrasynaptic receptors by low concentrations of ambient GABA. Extrasynaptic GABAA receptors are composed of receptor subunits that convey biophysical properties ideally suited to the generation of persistent inhibition and are pharmacologically and functionally distinct from their synaptic counterparts. This book highlights ongoing work examining the properties of recombinant and native extrasynaptic GABAA receptors and their preferential targeting by endogenous and clinically relevant agents. In addition, it emphasizes the important role of extrasynaptic GABAA receptors in GABAergic inhibition throughout the CNS and identifies them as a major player in both physiological and pathophysiological processes.
The small fruit fly, Drosophila melanogaster, has for over a century now had a large impact on biological and biomedical research; however, our knowledge of the fly brain has lagged significantly behind our understanding of other aspects of its development, physiology, and function. In The Making and Un-Making of Neuronal Circuits in Drosophila, innovative expert neuroscientists in the field present the ideas and concepts behind the methods, tools, and tricks that are currently being utilized to decode the secrets of this valuable insect's brain. Focused on the concept of a neuronal circuit, defined as a series of synaptically connected neurons subservient to a particular behavioral modality, this volume contains chapters dealing with anatomical analysis with a focus on cellular and sub-cellular morphologies. These detailed approaches fall under the headings of "Physiology" and "Behavior", conveniently divided the book into two sections. Written in the easy-to-follow Neuromethods series format, this work provides the kind of detailed description and implementation advice that is crucial for getting optimal results. Inventive and accessible, The Making and Un-Making of Neuronal Circuits in Drosophila provides the information and tools necessary to carry out current experiments and, more importantly, further advance the progress of the Drosophila neurobiology field and neurobiology in general.
Much of contemporary behavioral or cognitive neuroscience is concerned with discovering the neural basis of psychological processes such as attention, cognition, consciousness, perception, and memory. In sharp divergence from this field, An Odyssey Through the Brain, Behavior and the Mind can be regarded as an elaborate demonstration that the large scale features of brain electrical activity are related to sensory and motor processes in various ways but are not organised in accordance with conventional psychological concepts. It is argued that much of the traditional lore concerning the mind is based on prescientific philosophical assumptions and has little relevance to brain function. The first ten chapters of An Odyssey Through the Brain, Behavior and the Mind give a personal account of how the various discoveries that gave rise to these views came to be made. This is followed by discussions of brain organization in relation to behavior, learning and memory, sleep and consciousness, and the general problem of the mind.

This volume presents a variety of studies relating to the reach to grasp movement and provides a necessary and valuable contribution to the field of motor control. The professions covered in this book range from those interested in the basic sciences to those more interested in practical application. Neurophysiologists and biomechanists join with therapists and neural modelers to present an extensive overview of current developments. Evolutionary and developmental aspects are included together with descriptions of how this movement is affected by central nervous system damage. Purely theoretical aspects of the motor control of this movement are interspersed with treatment applications and robotics.
Recent studies have provided clear evidence on the role of neural-immune interactions in normal brain function and neuropathological conditions. Neuroimmune factors, which play an essential role in neuroinflammatory response, have been implicated in the regulation of neuronal function and plasticity. Thus, neural-immune interactions provide a new frame work for understanding the role of the neuroimmune system in normal brain function, neurodevelopment, and a variety of neurological disorders. These advances have a far reaching impact on many areas of neuroscience, including alcohol research. Studies using human alcoholic brains, gene knockout mice, and gene expression profiling have established a clear link between alcoholism and an altered neuroimmune profile. This book integrates emerging knowledge on neural-immune interactions with key discoveries in alcohol research and provides a comprehensive overview of neural-immune interactions in brain function and behavior associated with alcohol use disorders. While "Neural Immune Interaction in Brain Function and Alcohol Related Disorders" focuses on neural-immune interactions in areas directly related to alcohol use disorders, it is not intended to be all inclusive. Several areas, including sleep disorders, pain, and cholinergic anti-inflammatory pathways, are not covered as independent chapters but briefly mentioned in the text. The close relevance of these topics to neural-immune interactions and alcohol use disorders warrants future discussion and more research efforts."
Neurotransmission is a multicomponent process. Transmitters, released by neuronal activity, act on pre- and postsynaptic receptors, and many books detail advances in the receptor field. In addition, after their release from nerve endings, transmitters are removed from the neuronal vicinity by uptake into neuronal or glial cells by specific tra- porter proteins that have been studied intensely over the last 30 years; this information is scattered throughout numerous publishing vehicles. Therefore, the primary aim of this second edition of N- rotransmitter Transporters: Structure, Function, and Regulation is to offer a comprehensive picture of the characterization of neurotransmitter transporters and their biological roles. The transporter field has moved forward in stages. In the first phase, progress came from the use of substrate or blocker ligands selectively targeting transporters, the application of model systems allowing the study of transmitter tra- port shielded from storage, and the development of mathematical models for describing transport phenomena. In the second phase, roughly covering the last decade, advances in DNA techniques allowed the cloning of numerous genes coding for different transporter proteins. In the current, third stage, a wealth of information is being accumulated in studies relating transporter structure with function, experiments addressing regulation by posttranslational transfor- tion, investigations into transport modulation by trafficking processes and genomic influences, characterization of channel properties of tra- porters by electrophysiological approaches, and the creation of transgenic animals under- or overexpressing a given transporter protein.
There are now compelling human epidemiological and animal experimental data that indicate the risk of developing adult-onset complex diseases and neurological disorders are influenced by persistent epigenetic adaptations in response to prenatal and early postnatal exposures to environmental factors. Epigenetics refers to heritable changes in gene function that occur without a change in the sequence of the DNA. The main components of the epigenetic code are DNA methylation, histone modifications, and non-coding RNAs. The epigenetic programs are established as stem cell differentiate during embryogenesis, and they are normally faithfully reproduced during mitosis. Moreover, they can also be maintained during meiosis, resulting in epigenetic transgenerational disease inheritance, and also potentially introducing phenotypic variation that is selected for in the evolution of new species. The objective of this two volumebook is to provide evidence that environmental exposures during early development can alter the risk of developing medical conditions, such as asthma, autism, cancer, cardiovascular disease, diabetes, obesity, and schizophrenia later in life by modifying the epigenome. Consequently, epigenetic research promises to markedly improve our ability to diagnosis, prevent, and treat the pathological conditions of humans; however, it also introduces unique legal and ethical issues. This volume highlights the correlation between environmental factors and complex diseases, such as autism, addiction, neurological diseases, diabetes, obesity and cancer. It concludes with a chapter on legal and ethical implications of epigenetics. "
In the spring of 1987, I was in Havana, Cuba, where I was participating in planning a large-scale longitudinal study of the neurophysiological, neurochemical, and behavioral characteristics of cohorts of patients with cerebrovascular disease, depression, senile dementia, schizophrenia, or learning disabilities; and also part of this study were their first-degree blood relatives. This study was the outgrowth of a long-term project on the practical application of computer methods for the evaluation of brain electrical activity related to anatomical integrity, maturational development, and sensory, perceptual;.-and cognitive processes, especially in chil dren. For many years, that project had been supported by the United Nations Development Program (UNDP), the National Scientific Research Center of Cuba (CNIC), and the Ministries of Public Health and of Education of Cuba. Since its inception, I had served as a technical advisor to the UNDP project. When the project began, I became acquainted with Dr. Jose M. Miyar Barrueco, who was at that time the Rector of the Medical School of the University of Havana. Because of his keen interest in the new computer technology and its potential utility in developing countries, we met from time to time during my visits. These occasional meetings continued after he became Secretary of the Cuban Council of State, so that he could remain apprised of progress and problems with which he might help."
Information flow as nerve impulses in neuronal circuits is regulated at synapses. The synapse is therefore a key element for information processing in the brain. Much attention has been given to fast synaptic transmission, which predominantly regulates impulse-to-impulse transmission. Slow synaptic transmission and modu lation, however, sometimes have been neglected in considering and attempting to understand brain function. Slow synaptic potentials and modulation occur with a considerable delay in response to the accumulation of synaptic and modulatory inputs. In these contexts, they are plastic in nature and play important roles in information processing in the brain. A symposium titled "Slow Synaptic Responses and Modulation" was held as the satellite symposium to the 75th Annual Meeting of the Physiological Society of Japan on March 30-31, 1998, in Kanazawa. The theme was selected not only for the reason mentioned above, but also because of the considerable involvement of many Japanese scholars in establishing the basic issues. Following the dawn of synaptic physiological research, as Sir John Eccles, Sir Bernard Katz, and Professor Stephen Kuffler carried out pioneer work, Professor Kyozou Koketsu and Professor Benjamin Libet, the students of Sir John Eccles, and their colleagues established the concept of slow synaptic responses and modulation by studying vertebrate sympathetic ganglia. Since then, the concept has been ex panded with detailed investigations of both peripheral and central synapses at the levels of single ion channels, intracellular Ca"+ dynamics, intracellular transduc tion mechanisms, and genes.
Precision Medicine in Neurodegenerative Disorders, Part Two, Volume 193 deals with the "How" in the reconfiguration of our approach to slow the progression of those suffering from diseases of accelerated brain aging. This second Handbook of Clinical Neurology volume offers a rethinking of the animal models on which therapies are tested; outlines the progress and expected changes in biological subtyping efforts using lysosomal, endosomal, mitochondrial, immune dysregulation, and inflammatory mechanisms of disease pathophysiology; and the growing role of microbiome in shaping disease and as a future target of therapeutic efforts. The volume separates the potentially disease-modifying neurorescue and neurorestoration, (e.g., gene therapy and cell replacement therapy) from true precision medicine -matching the biology of those affected with the mechanism of the intervention of interest. Specific chapters are dedicated to the promise and challenges of extracellular vesicles for both diagnosis and treatment, the growing application of digital measures and other evaluations of clinical response, the nuts and bolts of novel adaptive clinical trial designs, and the regulatory changes needed to facilitate drug development for disease-modification purposes.
A few disorders have some of the same symptoms as schizophrenia including schizoaffective disorders, schizophreniform disorder, schizotypal and schizoid personality disorders, delusional disorder, and autism (schizophrenia spectrum disorders). Since the 2000 there has been significant progress in our understanding of the early presentations, assessment, suspected neuropathology, and treatment of these disorders. Recent technological breakthroughs in basic sciences hold promise for advancing our understanding of the pathophysiology of schizophrenia spectrum disorders. This collective monograph reviewers recent researches regarding the origins, onset, course, and outcome of schizophrenia spectrum disorders. In particular, this book will be illustrate new developments in terms of conceptual models, and research methodology, genetics and genomics, brain imaging and neurochemical studies, neurophysiology and information processing in schizophrenia spectrum disorders patients. Also will be highlighted new developments in our understanding of the childhood psychosis, prodromal and first-episode states, in treatment and rehabilitation. Thus, the purpose of this book is to provide up-to-date overview of the rapid advances made in the clinical and basic science studies supporting our understanding of the relationship between cerebral processes and clinical, cognitive and other presentations of the schizophrenia spectrum disorders. In addition, this book aims to monitor important research developments, which may be relevant to treatment, and rehabilitation of patients.
Translational Stroke Research: From Target Selection to Clinical Trials is part of "Springer Series in Translational Stroke Research." Forty-three chapters from leading stroke research groups around the world select future targets and methods for stroke management such as the vasculature and white matter, protein aggregation, neuroglobin, microRNAs, oxidation, soluble epoxide hydrolase, apoptosis, hypoxia-inducible factors, thrombin, toll- like receptor, angiogenesis, membrane potentials and pumps. The book discusses methods to regulate brain temperature and the use of preconditioning in stroke. It also presents new areas of research emphasizing restoration of function with growth factors and stem cells. It provides multiple animal models of both ischemic and hemorrhagic stroke in order to translate basic preclinical findings to clinical trials with de-risking issues, therapy delivery methods such as sustained-release and intranasal delivery, and potential therapies including cell therapies, albumin, transcranial laser, microbubbles, and ultrasound. Finally, it debates clinical trial design for analytical methodology, imaging, computation, and innovations.
This volume contains the proceedings of the Ninth European Conference on Eye Movements (ECEM 9), held in Ulm, Germany, on September 23-26, 1997. ECEM 9 con tinued a series of conferences initiated by Rudolf Groner of Bern, Switzerland, in 1981 which, from its very beginning, has brought together scientists from very diverse fields with a common interest in eye movements. About 40 of the papers presented at ECEM 9 have been selected for presentation in full length while others are rendered in condensed form. There is a broad spectrum of motives why people have become involved in, and fas cinated by, eye movement research. Neuroscientists have been allured by the prospect of understanding anatomical findings, single unit recordings, and the sequels of experimental lesions in terms of the clearly defined system requirements and the well documented be havioural repertoire of the oculomotor system. Others have been attracted by the richness of this repertoire and its dependence on an intricate hierarchy of factors spanning from "simple" reflexes to visual pattern recognition and spatio-temporal prediction. Neurolo gists, neuro-ophthalmologists and neuro-otologists have long standing experience with eye movements as sensitive indicators of lesions in the brain stem, the midbrain, and the cere bellum. By studying oculomotor malfunctions they have made, and are continuing to make, important contributions to our understanding of oculomotor functions."

The past 20 years have seen increasingly bold claims emanating from the field of neuroscience. Advances in medical imaging, brain modelling, and interdisciplinary cognitive science have forced us to reconsider the nature of social, cultural, and political activities. This collection of essays is the first to explore the relationship between neuroscience and political theory, with a view to examining what connections can be made and which claims represent a bridge too far. The book is divided into three parts: Part I: places neuroscience as a social and political practice into historical context Part II: weaves together the insights from contemporary neuroscience with the wisdom of major figures in the history of political thought Part III: considers how neuroscience can inform contemporary debates about a range of issues in political theory This work brings together scholars who are sceptical about the possibility of integrating neuroscience and political theory with proponents of a neuroscience-informed approach to thinking about political and social life. The result is a timely and wide-ranging collection of essays about the role that our brain might play in the life of the body politic. It should be essential reading for all those with an interest in the cutting edge of political theory.
This book describes the current state of understanding of the neurobiology of eating disorders, providing the latest insights and ideas. Because of the critical need to advance treatment, the book also includes chapters from pioneers in this field.
Intriguing new findings on how genes and environments work together through different stages of life take the spotlight in this significant collection. Studies from infancy to late adulthood show both forces as shaping individuals' relationships within family and non-family contexts, and examine how these relationships, in turn, continue to shape the individual. Transitional periods, in which individuals become more autonomous and relationships and personal identities become more complicated, receive special emphasis. In addition, chapters shed light on the extent to which the quantity and quality of genetic and environmental influence may shift across and even within life stages. Included in the coverage: Gene-environment interplay in parenting young children. The sibling relationship as a source of shared environment. Gene-environment transactions in childhood and adolescent problematic peer relationships. Toward a developmentally sensitive and genetically informed perspective on popularity. Spouse, parent, and co-worker: roles and relationships in adulthood. The family system as a unit of clinical care: the role of genetic systems. Behavioral geneticists, clinical psychologists, and family therapists will find in Gene-Environment Interplay in Interpersonal Relationships across the Lifespan a window into current thinking on the subject, new perspectives for understanding clients and cases, and ideas for further study.

Proceedings of Session VII of the Tenth International Symposium on Chromaffin Cell Biology, held August 25-28, 1999, in Bergen, Norway, and a post-symposium workshop on Chromogranins: from Fundamental Physiology to Clinical Aspects, held August 28, 1999, on board the coastal steamer MS Richard With. This book deals with the chromogranins, secretory prohormones from the diffuse neuroendocrine system. The current concepts of their structure, biogenesis, biosynthesis, secretion, tissue-specific distribution, and processing are presented for the first time all within one volume, with emphasis on the functional aspects of the biologically active sequences and the clinical perspectives of the circulation prohormones.
Neurovascular Coupling Methods brings the reader up to date with the current state-of-the-art techniques in measuring blood flow in the brain, with chapters describing different techniques or combinations of techniques, applied to specific species in either healthy or abnormal brains. Opening with a section on techniques in normal somatosensory processing, the detailed volume continues with parts covering techniques in normal visual processing, epilepsy and cerebrovascular diseases, such as ischemia, hemorrhage and spreading depression. As a collection in the popular Neuromethods series, this book contains the kind of thorough description and implementation advice that will lead to successful results in the lab. Authoritative and practical, Neurovascular Coupling Methods serves as an ideal guide for researchers aiming to further our knowledge of these coupling mechanisms in the hopes of ultimately understanding higher order functions such as language and memory and developing novel brain mapping techniques that can be employed in humans.
Metabolic syndrome as an important risk factor for stroke, Alzheimer disease, and depression presents readers with cutting edge and comprehensive information on relationship among metabolic syndrome, stroke, Alzheimer disease, and depression. It is hoped that this monograph will be useful to postgraduate students, faculty, research scientists, pharmacologists, nutritionists, and physicians, who are curious about the molecular mechanisms that link metabolic syndrome with stroke, Alzheimer disease, and depression.
The electric utility industry and its stakeholders in the.United States appear to be at a critical juncture in time. Powerful forces of global proportions are propelling the industry instinctively and in a secular fashion towards restructuring. That the industry will change is a fait accomplii. The nature and timing of the change is still a matter of intense debate, however. Because of the evolution of the industry into its present-day form, i.e. regulated local monopolies in their designated franchise service territories, the relative roles and expectations of various institutions would have to change to conform to the new state in the future. In either encouraging, or allowing this change to happen, society is essentially saying that future societal welfare would be better served by the changed structure contemplated. What that assumption translates into in more direct terms is that creation of future wealth would be better accomplished through redistribution of wealth today. Thoughtful individuals recognize the enormous responsibility placed upon the various entities empowered with jurisdiction over the timing and nature of the structural change. They are trying hard to bring analytical rigor to bear on the debate. One very critical element of this debate on restructuring is the issue of the treatment of transmission. The issue has been variously labeled transmission access, or pricing. Volumes have been written and spoken on this topic. |
