This book is the introduction to a series of e-books dedicated to the physiology and pathophysiology of neuroglia. The topic of neuroglia is generally overlooked in neuroscience curricula across the world, the main attention being focused on the description of excitability of neurons and neuronal networks. The neuroglia, being electrically non-excitable, are universally regarded as supportive cells which do not contribute to information processing. This oversimplified view, however, ignores the tremendous importance of brain homeostasis, which is imperative for the ongoing activity of neuronal networks. It also ignores the truth that specialization of neurons and their ability for rapid propagation and multi-level integration of signals become possible only because of delegation of homeostatic abilities to neuroglia. Furthermore, glial cells contribute to information processing as they can modulate neuronal synaptic transmission. Finally, neuroglia provide the only system of brain defense and as such these cells are intimately involved in all types of neuropathologies, and contribute to both neuroprotection and regeneration of the nervous system. The e-books in this series provide a platform for in-depth learning of all aspects of neuroglial cells function in health and disease.

"This volume is a very valuable and much needed contribution." –Quarterly Review of Biology AT LAST - A comprehensive, accessible textbook on glial neurobiology! Glial cells are the most numerous cells in the human brain but for many years have attracted little scientific attention. Neurophysiologists concentrated their research efforts instead, on neurones and neuronal networks because it was thought that they were the key elements responsible for higher brain function. Recent advances, however, indicate this isn’t exactly the case. Not only are astroglial cells the stem elements from which neurones are born, but they also control the development, functional activity and death of neuronal circuits. These ground-breaking developments have revolutionized our understanding of the human brain and the complex interrelationship of glial and neuronal networks in health and disease. Features of this book: an accessible introduction to glial neurobiology including an overview of glial cell function and its active role in neural processes, brain function and nervous system pathology an exploration of all the major types of glial cells including: the astrocytes, oligodendrocytes and microglia of the ACNS and Schwann cells of the peripheral nervous system; the book also presents a broad overview of glial receptors and ion channels an investigation into the role of glial cells in various types of brain diseases including stroke, neurodegenerative diseases such as Alzheimer's, Parkinson's and Alexander's disease, brain oedema, multiple sclerosis and many more a wealth of illustrations, including unique images from the authors' own libraries of images, describing the main features of glial cells Written by two leading experts in the field, Glial Neurobiology provides a concise, authoritative introduction to glial physiology and pathology for undergraduate/postgraduate neuroscience, biomedical, medical, pharmacy, pharmacology, and neurology, neurosurgery and physiology students. It is also an invaluable resource for researchers in neuroscience, physiology, pharmacology and pharmaceutics.

Glial Physiology and Pathophysiology provides a comprehensive, advanced text on the biology and pathology of glial cells. Coverae includes: the morphology and interrelationships between glial cells and neurones in different parts of the nervous systems the cellular physiology of the different kinds of glial cells the mechanisms of intra- and inter-cellular signalling in glial networks the mechanisms of glial-neuronal communications the role of glial cells in synaptic plasticity, neuronal survival and development of nervous system the cellular and molecular mechanisms of metabolic neuronal-glial interactions the role of glia in nervous system pathology, including pathology of glial cells and associated diseases - for example, multiple sclerosis, Alzheimer's, Alexander disease and Parkinson's Neuroglia oversee the birth and development of neurones, the establishment of interneuronal connections (the 'connectome'), the maintenance and removal of these inter-neuronal connections, writing of the nervous system components, adult neurogenesis, the energetics of nervous tissue, metabolism of neurotransmitters, regulation of ion composition of the interstitial space and many, many more homeostatic functions. This book primes the reader towards the notion that nervous tissue is not divided into more important and less important cells. The nervous tissue functions because of the coherent and concerted action of many different cell types, each contributing to an ultimate output. This reaches its zenith in humans, with the creation of thoughts, underlying acquisition of knowledge, its analysis and synthesis, and contemplating the Universe and our place in it.

The enteric nervous system (ENS) is a complex neural network embedded in the gut wall that orchestrates the reflex behaviors of the intestine. The ENS is often referred to as the “little brain” in the gut because the ENS is more similar in size, complexity and autonomy to the central nervous system (CNS) than other components of the autonomic nervous system. Like the brain, the ENS is composed of neurons that are surrounded by glial cells. Enteric glia are a unique type of peripheral glia that are similar to astrocytes of the CNS. Yet enteric glial cells also differ from astrocytes in many important ways. The roles of enteric glial cell populations in the gut are beginning to come to light and recent evidence implicates enteric glia in almost every aspect of gastrointestinal physiology and pathophysiology. However, elucidating the exact mechanisms by which enteric glia influence gastrointestinal physiology and identifying how those roles are altered during gastrointestinal pathophysiology remain areas of intense research. The purpose of this e-book is to provide an introduction to enteric glial cells and to act as a resource for ongoing studies on this fascinating population of glia. Table of Contents: Introduction / A Historical Perspective on Enteric Glia / Enteric Glia: The Astroglia of the Gut / Molecular Composition of Enteric Glia / Development of Enteric Glia / Functional Roles of Enteric Glia / Enteric Glia and Disease Processes in the Gut / Concluding Remarks / References / Author Biography

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.

During the second half of the 20th century, the introduction of a variety of new techniques greatly expanded our knowledge of the structure of nerve and neuroglial cells and of the organization of the nervous system at the cellular level. This new information has, however, generally been scattered throughout the literature, making it difficult for investigators to gain an overall vision of the discipline. The author has marshalled these scattered data to provide a systematic overview of the field placed within a historical context. He has correlated the major new findings with the classical notions of light microscopy and has integrated them with elements of biochemistry and cell physiology. After the publication of the first edition, the introduction of new microscopies and especially the growth of molecular biology have greatly expanded our knowledge, in particular on the intercellular communication in the nervous system and on the roles of neuroglial cells. These achievements have made a second edition of the book necessary. The fully revised and updated text, together with unique high-quality illustrations of structures of the central and peripheral nervous system, ensure that this new edition will be invaluable for neuroscientists, particularly those involved in cellular neuropathology, neurochemistry, neurophysiology and molecular neurobiology.

Every year, an estimated 1.7 million Americans sustain brain injury. Long-term disabilities impact nearly half of moderate brain injury survivors and nearly 50,000 of these cases result in death. Over the last decade, the field of neurotrauma has witnessed significant advances, especially at the molecular, cellular, and behavioral levels. This progress is largely due to the introduction of novel techniques, as well as the development of new animal models of central nervous system (CNS) injury. Brain Neurotrauma: Molecular, Neuropsychological, and Rehabilitation Aspects provides a comprehensive and up-to-date account on the latest developments in the area of neurotrauma, including brain injury pathophysiology, biomarker research, experimental models of CNS injury, diagnostic methods, and neurotherapeutic interventions as well as neurorehabilitation strategies in the field of neurotraum research. The book includes several sections on neurotrauma mechanisms, biomarker discovery, neurocognitive/neurobehavioral deficits, and neurorehabilitation and treatment approaches. In addition, a section is devoted to models of mild CNS injury, including blast and sport-related injuries. This book, with its diverse coherent content, is a valuable and comprehensive reference for individuals interested in the diverse and heterogeneous aspects of CNS pathology and/or rehabilitation needs.
