Molecular Biology Of The Neuron

Intended for use by advanced undergraduate, graduate and medical students, this book presents a study of the unique biochemical and physiological properties of neurons, emphasising the molecular mechanisms that generate and regulate their activity.

Nerve cells - neurons - are arguably the most complex of all cells. From the action of these cells comes movement, thought and consciousness. It is a challenging task to understand what molecules direct the various diverse aspects of their function. This has produced an ever-increasing amount of molecular information about neurons, and only in Molecular Biology of the Neuron can a large part of this information be found in one source. In this book, a non-specialist can learn about the molecules that control information flow in the brain or the progress of brain disease in an approachable format, while the expert has access to a wealth of detailed information from a wide range of topics impacting on his or her field of endeavour. The text is designed to achieve a balance of accessibility and broad coverage with up-to-date molecular detail. In the six years since the first edition of Molecular Biology of the Neuron there has been an explosion in the molecular information about neurons that has been discovered, and this information is incorporated into this second edition. Entirely new chapters have been introduced where recent advances have made a new aspect of neuronal function more comprehensible at the molecular level. Written by leading researchers in the field, the book provides an essential overview of the molecular structure and function of neurons, and will be an invaluable tool to students and researchers alike.

This book is a valuable compendium of up-to-date reviews of neuronal molecular biology by leading researchers in the field. It covers all aspects of neuron structure and function, with the emphasis on genetic and molecular analysis.

A central problem in neurobiology concerns mechanisms that generate the pro found diversity and specificity of the nervous system. What is the substance of diversification and specificity at the molecular, cellular, and systems levels? 4 How, for example, do 1011 neurons each form approximately 10 interconnec tions, allowing normal physiological function? How does disruption of these processes result in human disease? These proceedings represent the efforts of molecular biologists, embryologists, neurobiologists, and clinicians to approach these issues. in this volume are grouped by subject to present the varieties The chapters of methods used to approach each individual area. Section I deals with embry ogenesis and morphogenesis of the nervous system. In Chapter 3, Weston and co-workers describe the use of monoclonal antibodies that recognize specific neuronal epitopes (including specific gangliosides) for the purpose of defining heterogeneity in the neural crest, an important model system. Immunocyto chemical analysis reveals the existence of distinct sUbpopulations within the crest at extremely early stages; cells express neuronal or glial binding patterns at the time of migration. Consequently, interactions with the environment may select for predetermined populations. Le Douarin reaches similar conclusions in Chapter 1 by analyzing migratory pathways and developmental potentials in crest of quail-

The question of "what is thought" has intrigued society for ages, yet it is still a puzzle how the human brain can produce a myriad of thoughts and can store seemingly endless memories. All we know is that sensations received from the outside world imprint some sort of molecular signatures in neurons – or perhaps synapses – for future retrieval. What are these molecular signatures, and how are they made? How are thoughts generated and stored in neurons? The Biology of Thought explores these issues and proposes a new molecular model that sheds light on the basis of human thought. Step-by-step it describes a new hypothesis for how thought is produced at the micro-level in the brain – right at the neuron. Despite its many advances, the neurobiology field lacks a comprehensive explanation of the fundamental aspects of thought generation at the neuron level, and its relation to intelligence and memory. Derived from existing research in the field, this book attempts to lay biological foundations for this phenomenon through a novel mechanism termed the "Molecular-Grid Model" that may explain how biological electrochemical events occurring at the neuron interact to generate thoughts. The proposed molecular model is a testable hypothesis that hopes to change the way we understand critical brain function, and provides a starting point for major advances in this field that will be of interest to neuroscientists the world over. Written to provide a comprehensive coverage of the electro-chemical events that occur at the neuron and how they interact to generate thought Provides physiology-based chapters (functional anatomy, neuron physiology, memory) and the molecular mechanisms that may shape thought Contains a thorough description of the process by which neurons convert external stimuli to primary thoughts

Molecular Biology of the Neuron covers all aspects of neuron structure and function, including ion channels, receptors and signalling properties, synapse biology, and the genes and molecules involved in the development, maintenance, diseases, and death of neurons. The inheritance and expression of neuronal genes are also described, with particular emphasis on their relation to human disease. This book is a valuable compendium of comprehensive and up-to-date reviews of neuronal molecularbiology by leading researchers in the field. The focus throughout is on genetic and molecular analysis, and on present knowledge of molecular biological phenomena in neurons themselves, giving Molecular Biology of the Neuron its unique perspective. It is essential reading for clinical and systems neuroscientists, and a valuable reference source for all molecular neurobiologists.

This textbook provides an introduction to neuroscience, focusing particularly on the rapidly developing molecular aspects. The techniques of molecular biology are introduced and described in the context of their role in elucidating brain function at the molecular level.
