The hearing organs of non-mammals, which show quite large and systematic differences to each other and to those of mammals, provide an invaluable basis for comparisons of structure and function. By taking advantage of the vast diversity of possible study organisms provided by the "library" that is biological diversity, it is possible to learn how complex functions are realized in the inner ear through the evolution of specific structural, cellular and molecular configurations. Insights from Comparative Hearing Research brings together some of the most exciting comparative research on hearing and shows how this work has profoundly impacted our understanding of hearing in all vertebrates.
Foreword by Walter J. Freeman. The induction of unconsciousness using anesthetic agents demonstrates that the cerebral cortex can operate in two very different behavioral modes: alert and responsive vs. unaware and quiescent. But the states of wakefulness and sleep are not single-neuron properties---they emerge as bulk properties of cooperating populations of neurons, with the switchover between states being similar to the physical change of phase observed when water freezes or ice melts. Some brain-state transitions, such as sleep cycling, anesthetic induction, epileptic seizure, are obvious and detected readily with a few EEG electrodes; others, such as the emergence of gamma rhythms during cognition, or the ultra-slow BOLD rhythms of relaxed free-association, are much more subtle. The unifying theme of this book is the notion that all of these bulk changes in brain behavior can be treated as phase transitions between distinct brain states. Modeling Phase Transitions in the Brain contains chapter contributions from leading researchers who apply state-space methods, network models, and biophysically-motivated continuum approaches to investigate a range of neuroscientifically relevant problems that include analysis of nonstationary EEG time-series; network topologies that limit epileptic spreading; saddle--node bifurcations for anesthesia, sleep-cycling, and the wake--sleep switch; prediction of dynamical and noise-induced spatiotemporal instabilities underlying BOLD, alpha-, and gamma-band Hopf oscillations, gap-junction-moderated Turing structures, and Hopf-Turing interactions leading to cortical waves.
Vision is our primary sensory modality, and we are naturally curious as to how the visual system assembles. The visual system is in many ways remarkably simple, a repeating assemblage of neurons and support cells that parse the visual field through precision and redundancy. Through this simplicity the eye has often led the way in our exploration of how an organ is assembled. Eye development has therefore long been a favorite for exploring mechanisms of cell fate choice, patterning and cell signaling. This volume, which is part of the Current Topics in
Developmental Biology series, highlights the exceptional advances
over the past 20 years. Chapters emphasize our knowledge of
transcription factors and how these generate networks to direct the
eye field and associated structures. Topics such as cell fate
specification are also explored, along with the potential of
Drosophila as a model for lens formation and the progress made in
using the Drosophila eye to examine planar cell polarity. Review of our current state of knowledge Chapters written by authors with a new generation approach that takes a more systems approach to identifying factors and better defines cell subtypes
Adding to a vitally important cycle of publications covering the latest research developments in our understanding of neoplasms affecting the human central nervous system, this edition focuses on numerous aspects of pineal, pituitary, and spinal tumors. As with the previous volumes in the series, this latest work addresses a central imperative in cancer research the need to standardize classifications, written definitions and investigative guidelines in order to achieve a measure of shared objectivity among academics engaged in one of the most important medical endeavors of our era. It brings together the very latest work by oncologists, neurosurgeons, physicians, research scientists, and pathologists, providing the medical community with a wealth of data and results that, taken together, will advance the cause of cancer research. The volume synthesizes work on diagnosis, drug development, and therapeutic approaches that are typically scattered in a variety of journals and books. It features promising recent work in applying molecular genetics to clinical practice and evidence-based therapy, covering molecular profiling of tumors as well as a number of surgical treatments such as resection and radiosurgery. Together with its counterpart publications, it represents a much-needed central resource that will inform and guide future research efforts."
Damage to the central nervous system resulting from pathological mechanical loading can occur as a result of trauma or disease. Such injuries lead to significant disability and mortality. The peripheral nervous system, while also subject to injury from trauma and disease, also transduces physiological loading to give rise to sensation, and mechanotransduction is also thought to play a role in neural development and growth. This book gives a complete and quantitative description of the fundamental mechanical properties of neural tissues, and their responses to both physiological and pathological loading. This book reviews the methods used to characterize the nonlinear viscoelastic properties of central and peripheral neural tissues, and the mathematical and sophisticated computational models used to describe this behaviour. Mechanisms and models of neural injury from both trauma and disease are reviewed from the molecular to macroscopic scale. The book provides a comprehensive picture of the mechanical and biological response of neural tissues to the full spectrum of mechanical loading to which they are exposed. This book provides a comprehensive reference for professionals involved in pre prevention of injury to the nervous system, whether this arises from trauma or disease.
The evolution of vertebrate hearing is of considerable interest in the hearing community. However, there has never been a volume that has focused on the paleontological evidence for the evolution of hearing and the ear, especially from the perspective of some of the leading paleontologists and evolutionary biologists in the world. Thus, this volume is totally unique, and takes a perspective that has never been taken before. It brings to the fore some of the most recent discoveries among fossil taxa, which have demonstrated the sort of detailed information that can be derived from the fossil record, illuminating the evolutionary pathways this sensory system has taken and the diversity it had achieved.
This is a uniquely comprehensive reference that summarizes the
state of the art of signal processing theory and techniques for
solving emerging problems in neuroscience, and which clearly
presents new theory, algorithms, software and hardware tools that
are specifically tailored to the nature of the neurobiological
environment. It gives a broad overview of the basic principles,
theories and methods in statistical signal processing for basic and
applied neuroscience problems.
Mitochondria are essential organelles in eukaryotic cells that control such diverse processes as energy metabolism, calcium buffering, and cell death. Recent studies have revealed that changes in mitochondrial morphology by fission and fusion, a process known as mitochondrial dynamics, is particularly important for neuronal function and survival. Defects in this process are commonly found in neurodegenerative diseases, offering a new paradigm for investigating mechanisms of neurodegeneration. To provide researchers working on neurodegenerative diseases and mitochondria with updated information on this rapidly progressing field, we have invited experts in the field to critically review recent progresses and identify future research directions. The topics include genetics of mitochondrial dynamics, mitochondrial dynamics and bioenergetics, autophagy, apoptosis, and axonal transport, and its role in neurological diseases, including Alzheimer s, Parkinson s, and Huntington 's diseases.
Arterial chemoreceptors are unique structures which continuously monitor changes in arterial blood oxygen, carbon dioxide, glucose, and acid. Alterations in these gases are almost instantaneously sensed by arterial chemoreceptors and relayed into a physiological response which restores blood homeostasis. Arterial Chemoreception contains updated material regarding the physiology of the primary arterial chemoreceptor; the carotid body. Moreover, this book also explores tantalizing evidence regarding the contribution of the aortic bodies, chromaffin cells, lung neuroepithelial bodies, and brainstem areas involved in monitoring changes in blood gases. Furthermore this collection includes data showing the critical importance of these chemoreceptors in the pathophysiology of human disease and possible therapeutic treatments. This book is a required text for any researcher in the field of arterial chemoreception for years to come. It is also a critical text for physicians searching for bench-to-bedside treatments for heart failure, sleep apnea, and pulmonary hypertension.
Two sigma receptor subtypes have been proposed, sigma1 and 2. Much of our understanding of this system is based on biochemical and pharmacological characterization of the cloned sigma1 receptor subtype (Sigma1). It has become clear that sigma receptors are not canonical receptors. Sigma1 is highly conserved among mammalian species, however, it does not share significant homology with any other mammalian protein. Although a range of structurally diverse small molecules bind Sigma1 with high affinity, and it has been associated with a broad range of signaling systems, Sigma1 itself has no known signaling or enzymatic activity. The evolution of this field over nearly four decades has more recently led to a fundamental shift in the concept of "sigma receptors" to what may more accurately and generally be called sigma proteins. Largely based on traditional pharmacologic approaches, the Sigma1 protein has been associated with a broad range of signaling systems, including G-protein coupled receptors, NMDA receptors, and ion channels. Sigma proteins have been linked to a range of physiological processes, including intracellular calcium signaling, neuroprotection, learning, memory, and cognition. Emerging genetic, clinical, and mechanism focused molecular pharmacology data demonstrate the involvement of proteins in a range of pathophysiologies and disorders including neurodegenerative disease, pain, addiction, psychomotor stimulant abuse, and cancer. However, an understanding of the physiological role of sigma proteins has remained elusive. Emerging data associate Sigma1 with chaperone-like activities or molecular scaffold functions. This book aims to provide an updated perspective on this rapidly evolving field undergoing changes in fundamental concepts of key importance to the discipline of pharmacology. It focusses on the reported roles of sigma proteins in pathophysiology and on emergent therapeutic initiatives.
Psychophysiology is an ever expanding field. The application of psychophysiological investigations to psychiatric disorders is likewise expanding and has in fact shed much light on some of the neural processes contributing to the development of psychiatric symptoms and/or their amelioration following treatment. In the first part of this volume, we have selected a number of conditions where psychophysiological investigations have recently provided some insight into the pathophysiology of a particular manifestation (e.g., dissociation) or a disorder. Although this volume has a main focus on electrophysiological investigative modalities where neuroimaging was complimentary this added insight was included. The second part of the volume focuses on novel uses of psychophysiological measures, combining it with neuropsychology and imaging where possible, in the context of neuropsychiatric research and describes advanced analytical tools. Both basic and clinical investigators in this field should find the reviews and interpretations provided clear and informative. Clinicians will find this volume easy to assimilate. While direct clinical applications may be down the road, the insights provided should help the practicing clinicians to have firmer understanding of the complexity of the disorder they manage in everyday practice.
A brain-computer interface (BCI) establishes a direct output channel between the human brain and external devices. BCIs infer user intent via direct measures of brain activity and thus enable communication and control without movement. This book, authored by experts in the field, provides an accessible introduction to the neurophysiological and signal-processing background required for BCI, presents state-of-the-art non-invasive and invasive approaches, gives an overview of current hardware and software solutions, and reviews the most interesting as well as new, emerging BCI applications. The book is intended not only for students and young researchers, but also for newcomers and other readers from diverse backgrounds keen to learn about this vital scientific endeavour.
This volume provides the reader with a pathophysiological perspective on the role of CNS in puberty and adolescence, starting from genetic/molecular aspects, going through structural/imaging changes and leading to physical/behavioral characteristics. Therefore, renowned investigators involved in both animal and human research shared recent data as well as overall appraisal of relevant questions around CNS control of puberty and adolescence. No doubt that this volume will inspire those involved in either scientific research or clinical practice or both in the fascinating field of puberty and adolescence.
In a singularly fundamental challenge to the positions widespread among social scientists, White distances himself from the reductionist models of the human brain. He asserts, basing his thought on the authoritative findings of modern neuroscientists, the causal potency of human self-awareness. The acceptance of such a potential in mankind transforms the behavioral sciences into the science of human action. Implicit in the evolutionary context of this perspective is a basic indeterminism inherent in human science. White stresses the central role of conscious purpose in human action and emphasizes the importance of choice and its consequences at the level of political community. In urging a consideration of the significance that neuroscience has for the behavioral sciences, White explores truly basic issues at the heart of those disciplines. He makes a persuasive case for interpreting human action as purposeful, conscious, choice-based, and cumulatively unpredictable.
The successful previous volume on this topic provided a detailed benchwork manual for the most commonly used animal models of acute neurological injuries including cerebral ischemia, hemorrhage, vasospasm, and traumatic brain and spinal cord injuries. Animal Models of Acute Neurological Injuries II: Injury and Mechanistic Assessments aims to collect chapters on assessing these disorders from cells and molecules to behavior and imaging. These comprehensive assessments are the key for understanding disease mechanisms as well as developing novel therapeutic strategies to ameliorate or even prevent damages to the nervous system. Volume 2 examines global cerebral ischemia, focal cerebral ischemia, and neonatal hypoxia-ischemia, as well as intensive sections covering traumatic brain injury and spinal cord injury. Designed to provide both expert guidance and step-by-step procedures, chapters serve to increase understanding in what, why, when, where, and how a particular assessment is used. Accessible and essential, Animal Models of Acute Neurological Injuries II: Injury and Mechanistic Assessments will be useful for trainees or beginners in their assessments of acute neurological injuries, for experienced scientists from other research fields who are interested in either switching fields or exploring new opportunities, and for established scientists within the field who wish to employ new assessments.
The role that placebos play in many treatments is clear: they not only play a complimentary role in various treatment options but they can sometimes be the only beneficial option for treatment. Brain imaging studies over the past decade have shown that placebo-treated patients undergo some of the same changes in brain activity as those treated with pharmacologically active substances. Yet this important component of healing is not yet harnessed in clinical settings. The Placebo Effect in Clinical Practice brings together what we know about the mechanisms behind the placebo response, as well as the procedures that promote these responses, in order to provide a focused and concise overview on how current knowledge can be applied in treatment settings. An introductory chapter documents the ubiquity and extent of the placebo response and discusses the history of the placebo response in relation to medical treatment. Several subsequent chapters focus on how placebos work and how the placebo effect can be enhanced. Expectation, conditioning and elements of the treatment situation are covered in separate chapters. The relationship between psychotherapy and placebo treatment is covered as is the ethics of deliberate use of the placebo effect. Because placebo effects are particularly prominent in some psychiatric conditions, particular attention is given to the role of the placebo response in psychiatric treatment. The final chapter summarizes what we currently know and offers concrete suggestions for how what we know of the placebo effect can be used to enhance the benefit of all treatments.
Bringing together techniques and methods currently being applied to the study of exocytosis, "Exocytosis Methods" collects chapters from experts in the field, examining this fundamental process essential to functions ranging from protein secretion to hormone release and neurotransmission. The book begins with a section covering a range of techniques being applied to the study of single-vesicle fusion events, which are key in order to gain insight into the final steps of vesicle fusion. The volume continues with several model systems that are being employed to unravel the complexities of exocytosis. Written for the "Neuromethods" series, chapters included in this work present the kind of detail and vital implementation advice that leads to successful results. Practical and authoritative, "Exocytosis Methods" seeks to promote the advent of new methods in microscopy and the development of new preparations, which would doubtlessly lead to many new and exciting discoveries in this field."
Behavioral neuroscience encompasses the disciplines of neurobiology and psychology to study mechanisms of behavior. This volume provides a contemporary overview of the current state of how ethics informs behavioral neuroscience research. There is dual emphasis on ethical challenges in experimental animal approaches and in clinical and nonclinical research involving human participants.
Neuropsychiatric disorders such as schizophrenia, mood disorders, Alzheimer s disease, epilepsy, alcoholism, substance abuse and others are one of the most debilitating illnesses worldwide characterizing by the complexity of the causes, and lacking the laboratory tests that may promote diagnostic and prognostic procedures. Recent advances in neuroscience, genomic, genetic, proteomic and metabolomic knowledge and technologies have opened the way to searching biomarkers and endophenotypes, which may offer powerful and exciting opportunity to understand the etiology and the underlying pathophysiological mechanisms of neuropsychiatric disorders. The challenge now is to translate these advances into meaningful diagnostic and therapeutic advances. This book offers a broad synthesis of the current knowledge about diverse topics of the biomarker and endophenotype strategies in neuropsychiatry. The book is organized into four interconnected volumes: Neuropsychological Endophenotypes and Biomarkers (with overview of methodological issues of the biomarker and endophenotype approaches in neuropsychiatry and some technological advances), Neuroanatomical and Neuroimaging Endophenotypes and Biomarkers, Metabolic and Peripheral Biomarkers and Molecular Genetic and Genomic Markers . The contributors are internationally and nationally recognized researchers and experts from 16 countries. This four-volume handbook is intended for a broad spectrum of readers including neuroscientists, psychiatrists, neurologists, endocrinologists, pharmacologists, clinical psychologists, general practitioners, geriatricians, health care providers in the field of neurology and mental health interested in trends that have crystallized in the last decade, and trends that can be expected to further evolve in the coming years. It is hoped that this book will also be a useful resource for the teaching of psychiatry, neurology, psychology and mental health. "
During the past two decades, there has been a dramatic increase in interest in the study of ageing-related changes in cognitive abilities. In this volume researchers from a variety of theoretical perspectives discuss adult age differences in a wide range of cognitive skills. Of special interest is the extent to which ageing effects on performance are related to variations in the representation, organization and utilization of knowledge, broadly defined. Recent research and theory in the field of ageing has emphasized the need to examine such processes more closely in order to provide a more complete understanding of ageing effects on cognitive behaviour.
This book focuses on neuro-engineering and neural computing, a multi-disciplinary field of research attracting considerable attention from engineers, neuroscientists, microbiologists and material scientists. It explores a range of topics concerning the design and development of innovative neural and brain interfacing technologies, as well as novel information acquisition and processing algorithms to make sense of the acquired data. The book also highlights emerging trends and advances regarding the applications of neuro-engineering in real-world scenarios, such as neural prostheses, diagnosis of neural degenerative diseases, deep brain stimulation, biosensors, real neural network-inspired artificial neural networks (ANNs) and the predictive modeling of information flows in neuronal networks. The book is broadly divided into three main sections including: current trends in technological developments, neural computation techniques to make sense of the neural behavioral data, and application of these technologies/techniques in the medical domain in the treatment of neural disorders.
At the beginning of the 20th century, German biologist Jakob von Uexkull created the concept of "Umwelt" to denote the environment as experienced by a subject. This concept of environment differs from the idea of passive surroundings and is defined not just by physical surroundings, but is rather a "subjective universe," a space weighted with meaning. Today, neuroscience provides a new way to look at the brain s capability to create a representation of the world. At the same time behavioural specialists are demonstrating that animals have a richer mental universe than previously known. Philosophical reflection thus finds itself with more experimental and objective data as well. Nearly a century after the publication of von Uexkull s founding work ("Umwelt und Innenwelt der Tiere" was published in 1909), neurobiologists, psychologists, sociologists, anthropologists, ethologists, and philosophers revisit his mail concept at the light of modern science"
In recent years, music theorists have been increasingly eager to incorporate findings from the science of human cognition and linguistics into their methodology. In the culmination of a vast body of research undertaken since his influential and award-winning Conceptualizing Music (OUP 2002), Lawrence M. Zbikowski puts forward Foundations of Musical Grammar, an ambitious and broadly encompassing account on the foundations of musical grammar based on our current understanding of human cognitive capacities. Musical grammar is conceived of as a species of construction grammar, in which grammatical elements are form-function pairs. Zbikowski proposes that the basic function of music is to provide sonic analogs for dynamic processes that are important in human cultural interactions. He focuses on three such processes: those concerned with the emotions, the spontaneous gestures that accompany speech, and the patterned movement of dance. Throughout the book, Zbikowski connects cognitive research with music theory for an interdisciplinary audience, presenting detailed musical analyses and summaries of the basic elements of musical grammar. |
