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.
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.
This volume explores how the principles and values of pragmatic philosophy serve as orienting perspectives for critical thinking in contemporary psychotherapy and clinical practice. Drawing on the contributions of William James and John Dewey, Neuroscience, Psychotherapy, and Clinical Pragmatism introduces a model of clinical pragmatism emphasizing the individuality of the person, open-ended dialogue, experiential learning, and the practical outcomes of ideas and methods. In a second part, chapters show how recent developments in neuroscience and interpersonal neurobiology deepen our understanding of change and growth in accord with the principles of clinical pragmatism. Finally, the volume reviews paradigms of psychotherapy across the psychodynamic, behavioral, cognitive, and humanistic traditions. Case studies show how the pluralist orientation of clinical pragmatism enlarges concepts of therapeutic action. This text has been written for psychotherapists as well as scholars, educators, and trainees in the fields of psychiatry, clinical psychology, counseling, and social work.
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. "
This book provides a comprehensive overview of the role of neuroglia in neurodegenerative diseases. Neuroglia are the most abundant cells in the nervous system and consist of several distinct cell types, such as astrocytes, oligodendrocytes,and microglia. Accumulating evidence suggests that neuroglia participate in the neurodegenerative process, and as such are essential players in a variety of diseases, including Alzheimer's, Parkinson's, and Huntington's. Intended for researchers and students, the book presents recent advances concerning the biology of neuroglia as well as their interaction with neurons during disease progression. In addition, to highlight the function of neuroglia in different types of neurodegenerative disease, it also discusses their mechanisms and effects on protecting or damaging neurons.
Virtual Reality (VR) offers the potential to develop human testing and training environments that allow for the precise control of complex stimulus presentations in which human cognitive and functional performance can be accurately assessed and rehabilitated. However, basic feasibility and human issues need to be addressed in order for this technology to be reasonably and efficiently applied in clinical psychology. The book, written in a scholarly style, will provide rationales for virtual reality's applicability in clinical psychology. We will review the relevant literature regarding theoretical and pragmatic issues for these applications, and provide a description of ongoing work developed world-wide. The topics directly involve critical issues for clinicians, designers and users, and will be discussed with scientific competence without neglecting clarity and empirical cases with suggestions for actual use. The book is divided in three main sections: VR in clinical psychology: opportunities and challenges, VR in treatment of phobias and VR in clinical assessment and therapy.
The development of new photochemical tools, some synthesized by chemists and some provided by nature, is rapidly changing the way neurobiological research is performed in the modern laboratory. In "Photosensitive Molecules for Controlling Biological Function," expert researchers in the field examine the most cutting-edge tools currently available. Divided into three sections, this detailed compendium features techniques involving natural photosensitive proteins, caged neurotransmitters, and small molecule photoswitches that bestow light sensitivity on ion channels and receptors. Written for the "Neuromethods" series, this volume features the type of meticulous description and implementation advice that is crucial for getting optimal results in the lab. Authoritative and practical, "Photosensitive Molecules for Controlling Biological Function" provides an unbiased comparison of the various photochemical tools currently available for controlling neuronal activity in order to aid scientists in the vital goal of choosing the right tools for the right job.
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.
oltage-gated calcium channels are essential mediators of a range of physiological functions, including the communication between nerve Vcells, the regulation of heart beat, muscle contraction, and secretion of hormones such as insulin. Consequently, these channels are critical phar macological targets in the treatment of a variety of disorders, such as epi lepsy, hypertension, and pain. Voltage-gated calcium channels have there fore been subject to intense study by numerous investigators over the past few decades, and an immense body of work has accumulated. In this book, we provide the first comprehensive overview of our current state of knowl edge concerning this exciting field of research. Leading off with a general review of calcium signaling and techniques to measure calcium channel ac tivity, the book delves into a provocative overview of the history of the cal cium channel field, contributed by one of the key pioneers in the field. Dr. Richard Tsien. This is followed by an in depth review of the biochemical and molecular biological characterization of calcium channel genes by Drs. Catterall and Snutch whose research has resulted in major advances in the calcium channel field. A number of chapters are dedicated towards various aspects of calcium channel structure and function, including channel gat ing, permeation, modulation and interactions with members of the exo- totic machinery-contributed by both established leaders and rising stars in the field."
Over the years there has been growing interest among the scientific community in investigating sleep and how it affects the memory and other brain functions. It is now well established that sleep helps in memory consolidation and induction of neural plasticity, and that short-term deprivation of either total sleep or rapid eye movement sleep alone can induce memory deficits very quickly. Quantitative and qualitative changes in sleep architecture after different training tasks further suggest that discrete memory types may require specific sleep stage/s for optimal memory consolidation, and studies indicate that sleep deprivation alters synaptic plasticity and membrane excitability in the hippocampal neurons and synaptic up-scaling in the cortical neurons. Further, sleep alteration during pregnancy may increase the risk of depression and adversely affect maternal-child relationships, parenting practices, family functioning, and children's development and general wellbeing. This book coherently discusses all these aspects, with a particular focus on the possible role of sleep in memory consolidation and synaptic plasticity. It also highlights the detrimental effects of sleep loss on mental health, the immune system and cognition. This book is a valuable reference resource for students and researchers working in the area of sleep, memory, or neuronal plasticity.
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.
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."
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."
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.
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.
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.
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.
Although the fundamental principles of vocal production are well-understood, and are being increasingly applied by specialists to specific animal taxa, they stem originally from engineering research on the human voice. These origins create a double barrier to entry for biologists interested in understanding acoustic communication in their study species. The proposed volume aims to fill this gap, providing easy-to-understand overviews of the various relevant theories and techniques, and showing how these principles can be implemented in the study of all main vertebrate groups. The volume will have eleven chapters assembled from the world's leading researchers, at a level intelligible to a wide audience of biologists with no background in engineering or human voice science. Some will cover sound production in a particular vertebrate group; others will address a particular issue, such as vocal learning, across vertebrate taxa. The book will highlight what is known and how to implement useful techniques and methodologies, but will also summarize current gaps in the knowledge. It will serve both as a tutorial introduction for newcomers and a springboard for further research for all scientists interested in understanding animal acoustic signals.
This book highlights the behavioral and neurobiological issues relevant for drug development, reviews evidence for an innovative approach for drug discovery and presents perspectives on multiple special topics ranging from therapeutic drug use in children, emerging technologies and non-pharmacological approaches to cognitive enhancement.
Tinnitus is a prevalent hearing disease, affecting 15% of the population, particularly hearing impaired, veterans and even young people who grow up with mp3 players and iPods. The mechanisms underlying tinnitus remain controversial. At present there is no cure for tinnitus, and treatment options are limited. Different from previous tinnitus books, including A. R. Moller's book [in press at Springer], which typically have a strong clinical flavor, the present volume focuses on neural mechanisms of tinnitus and its behavioral consequences. The proposed book starts with a general summary of the field and a short introduction on the selection and content of the remaining chapters. Chapter 2 overviews tinnitus prevalence and etiologies to set the tone for significance and complexity of this neurological disorder spectrum. Chapters 3-8 cover neuroscience of tinnitus in animal models from molecular mechanisms to cortical manifestation. Chapters 9-12 cover human brain responses to tinnitus and it clinical management.
This monograph provides a comprehensive overview of the latest advances in the field of vasopressin and oxytocin. In the summer of 1997, scientists from over 20 countries congregated in Montreal for the 1997 World Congress of Neurohypophysial Hormones, a conference that united the fields of vasopressin, neurohypophysis, and oxytocin in a single joint meeting that gave rise to this book. The organization of a joint meeting was prompted by several developments. Specifically the molecular characterization of the vasopressin/oxytocin receptor family made it mandatory to adopt an integrated view and to discuss the vasopressin/oxytocin ligand/receptor family as a whole. To ensure emphasis on novelty, the conference focused on advances made in the late-1990s and also included important contributions by scientist that had not previously been associated with the vasopressin/oxytocin field.
Cerebral Cortex is a comprehensive and detailed work covering the dual nature of the organization of the architecture and connections of the cerebral cortex. After establishing the evolutionary approach of the cerebral cortex's origin, the authors have systematically analyzed, in detail, the common principle underlying the structure and connections of sensory and motor systems. This important book describes the frontal, limbic, and multimodal association areas, as well as the long fiber pathways in a similar manner. The anatomical investigations have been complimented with current clinical and experimental observations, as well as neuroimaging studies. This unique approach, exploring the underlying principle of the architecture and connections of the cerebral cortex, has previously never been undertaken. In the concluding chapter of the book, the authors have provided the usefulness of such an approach for future investigations. Cerebral Cortex provides extensive illustrations, along with historical references to each sensory, motor and association systems.
As a career sociologist I ?rst became interested in neurosociology around 1987 when a graduate student lent me Michael Gazzaniga's The Social Brain. Ifthe biological human brain was really social, I thought sociologists and their students should be the ?rst, not the last, to know. As I read on I found little of the clumsy reductionism of the earlier biosociologists whom I had learned to see as the arch- emy of our ?eld. Clearly, reductionism does exist among many neuroscientists. But I also found some things that were very social and quite relevant for sociology. After reading Descarte's Error by Antonio Damasio, I learned how some types of emotion were necessary for rational thought - a very radical innovation for the long-honored "objective rationalist. " I started inserting some things about split-brain research into my classes, mispronouncing terms like amygdala and being corrected by my s- dents. That instruction helped me realize how much we professors needed to catch up with our students. I also wrote a review of Leslie Brothers' Fridays Footprint: How Society Shapes the Human Mind. I thought if she could write so well about social processes maybe I could attempt to do something similar in connection with my ?eld. For several years I found her an e-mail partner with a wonderful sense of humor. She even retrieved copies of her book for the use of my graduate students when I had assigned it for a seminar.
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.
What goes on in creative writers' heads when they write? What can cognitive psychology, neuroscience, literary studies and previous research in creative writing studies tell creative writers about the processes of their writing mind? Creative writers have for centuries undertaken cognitive research. Some described cognition in vivid exegetical essays, but most investigated the mind in creative writing itself, in descriptions of the thinking of characters in fiction, poetry and plays. The inner voicings and inner visualising revealed in Greek choruses, in soliloquies, in stream-of-consciousness narratives are creative writers' 'research results' from studying their own cognition, and the thinking of others. The Creative Writer's Mind is a book for creative writers: it sets out to cross the gap between creative writing and science, between the creative arts and cognitive research. |
