Frontiers In Pharmacology Of Neurotransmitters

Numerous phenomenal advances have been made towards understanding the role of neurotransmitters in the pathophysiology of neurological disorders, and these have resulted in a large number of novel molecules with the potential to revolutionize the treatment and prevention of such disorders. This book provides a comprehensive and detailed explanation of brain neurotransmitters and their receptors and associated channels. It includes a basic introduction, and also discusses the functions and recent advances and their pharmacology, highlighting the role of various computer aided drug design (CADD) strategies for the development of therapeutic ligands to modulate these receptors/ion channels. Written in an easy-to-read style, it is intended for neuroscience and pharmaceutical students and researchers working in the area of brain neurotransmitters.

This eBook is a collection of articles from a Frontiers Research Topic. Frontiers Research Topics are very popular trademarks of the Frontiers Journals Series: they are collections of at least ten articles, all centered on a particular subject. With their unique mix of varied contributions from Original Research to Review Articles, Frontiers Research Topics unify the most influential researchers, the latest key findings and historical advances in a hot research area!

A comprehensive, multidisciplinary review, Neural Plasticity and Memory: From Genes to Brain Imaging provides an in-depth, up-to-date analysis of the study of the neurobiology of memory. Leading specialists share their scientific experience in the field, covering a wide range of topics where molecular, genetic, behavioral, and brain imaging techniques have been used to investigate how cellular and brain circuits may be modified by experience. In each chapter, researchers present findings and explain their innovative methodologies. The book begins by introducing key issues and providing a historical overview of the field of memory consolidation. The following chapters review the putative genetic and molecular mechanisms of cell plasticity, elaborating on how experience could induce gene and protein expression and describing their role in synaptic plasticity underlying memory formation. They explore how putative modifications of brain circuits and synaptic elements through experience can become relatively permanent and hence improve brain function. Interdisciplinary reviews focus on how nerve cell circuitry, molecular expression, neurotransmitter release, and electrical activity are modified during the acquisition and consolidation of long-term memory. The book also covers receptor activation/deactivation by different neurotransmitters that enable the intracellular activation of second messengers during memory formation. It concludes with a summary of current research on the modulation and regulation that different neurotransmitters and stress hormones have on formation and consolidation of memory.

Brain aminergic pathways are organized in parallel and interacting systems, which support a range of functions, from homoeostatic regulations to cognitive, and motivational processes. Despite overlapping functional influences, dopamine, serotonin, noradrenaline and histamine systems provide different contributions to these processes. The histaminergic system, long ignored as a major regulator of the sleep-wake cycle, has now been fully acknowledged also as a major coordinator of attention, learning and memory, decision making. Although histaminergic neurons project widely to the whole brain, they are functionally heterogeneous, a feature which may provide the substrate for differential regulation, in a region-specific manner, of other neurotransmitter systems. Neurochemical preclinical studies have clearly shown that histamine interacts and modulates the release of neurotransmitters that are recognized as major modulators of cognitive processing and motivated behaviours. As a consequence, the histamine system has been proposed as a therapeutic target to treat sleep-wake disorders and cognitive dysfunctions that accompany neurodegenerative and neuroinflammatory pathologies. Last decades have witnessed an unexpected explosion of interest in brain histamine system, as new receptors have been discovered and selective ligands synthesised. Nevertheless, the complete picture of the histamine systems fine-tuning and its orchestration with other pathways remains rather elusive. This Research Topic is intended to offer an inter-disciplinary forum that will improve our current understanding of the role of brain histamine and provide the fundamentals necessary to drive innovation in clinical practice and to improve the management and treatment of neurological disorders.

Providing an essential brainstem relay for three cranial nerves, the NST coordinates highly complex sensory information. While other functions of the NST have received attention, its role in gustatory processing has received little. The first reference devoted exclusively to gustatory processing, The Role of the Nucleus of the Solitary Tract in Gustatory Processing offers an in-depth review of one of the most important central relay stations in the brain. Combining widely dispersed research into a comprehensive single volume, it presents a thorough historical background, documents the anatomy of the rostral nucleus of the solitary tract (rNST), and explores the properties of synaptic transmitters and neurons within that tract. The book examines the role of reflex activities and considers factors that influence how gustatory rNST neurons respond to taste stimuli. It describes the development and maturational changes the rNST undergoes and considers the challenge involved with identifying rNST neural circuits. The Role of the Nucleus of the Solitary Tract in Gustatory Processing brings together expert investigators who have contributed substantially to the current knowledge of the anatomy, physiology, and developmental biology of the solitary nucleus. This pertinent work serves as a standard reference for those involved in the field, providing ready access to past investigations and inviting practitioners to create new approaches that will advance knowledge about the central processing of gustatory information.

Yawning is a stereotyped phylogenetically ancient phenomenon that occurs in almost all vertebrates. As an emotional behavior and an expressive movement, yawning has many consequences; nevertheless, it has so far been poorly addressed in medical research and practice. Bringing together the latest research from many fields, this volume integrates current insights within embryology, ethology, neurophysiology, psychology, fMRI and pathology. The phylogenetic and ontogenetic aspects of yawning offer an interesting perspective on human development, and its occurrence in neurological diseases - an area explored by only a few investigators - may provide useful clinical information. This book will make valuable and fascinating reading to neurologists, sleep specialists, psychologists, ethologists and pharmacologists, as well as to anybody interested in uncovering the mystery of yawning.

Understanding the phenomenon of long-lasting vulnerability to addiction is essential to developing successful treatments. Written by an international team of authorities in their respective fields, Advances in the Neuroscience of Addiction provides an excellent overview of the available and emerging approaches used to investigate the biologic mechanisms of drug addiction. It also delineates the promising research discoveries being made in relapse prevention. The book begins with current animal models of addiction, which mimic the state of humans entering treatment: recently-abstinent animals that receive common triggers for relapse (classical conditioning, stress, and neuroadaptive dysregulation). Coverage then shifts to the use of electrophysiologic approaches, which enable researchers to characterize the discharge patterns of single neurons during drug self-administration. After exploring advances in voltammetry and enzyme-linked biosensors for measuring glutamate, the book discusses the theoretical background and results of neuroimaging studies related to neuronal networks that are activated by drug-specific cues. It then describes modern genetic approaches to manipulate target proteins that influence addictive behavior. The book rounds out its coverage by illustrating how a neuroeconomic approach can inform studies of reward processing in general and addiction in particular. It is a comprehensive introduction to the methodologies of the field for students and beginning researchers and an essential reference source for established investigators.
