Book Description
Recent years have witnessed a resurgence of interest in the possible role of brain acetylcholine in neuropsychiatric disease. Research in this area has involved the renewed investigation of the cholinomimetics physostigmine and arecoline, and has been facilitated by the development of new potential cholinomimetics such as dimethylaminoethanol (Deanol) and choline chloride. Current investigators also have taken advantage of new approaches to neurochemical studies. Increasingly sensitive assay techniques such as gas chromatography/mass spectrometry have allowed investigators to measure low concentra tions of choline and acetylcholine in brain tissues. Improved neuroanatomical procedures such as immunohistochemical staining and the use of microelectrodes and micropipets have enabled skilled investigators to begin to map central acetylcholine pathways and to dissect the component parts of the complex interactions between brain acetylcholine and other neurotransmitters. The convergence of data from both clinical and basic studies now suggest that brain acetylcholine may be involved in affective illness, several movement disorders, and some cognitive disturbances. The purpose of this book is to summarize recent clinical and pre-clinical investigations on the possible role of brain acetylcholine in several neurological and psychiatric disorders. The volume is divided into six major sections: (1) Brain Acetylcholine and Psychiatric Disorders; (2) Brain Acetylcholine and Movement Disorders; (3) Brain Acetylcholine and Cognitive Function; (4) The Electrophysiology of Cholinergic Agents; (5) Interactions of Brain Acetylcholine and Other Neurotransmitters; (6) Biochemical and Pharmacological Aspects of CholinergiC Treatment Strategies.

Book Description
Much of our understanding of brain physiology has focused on what one might call, first order processes. These essentially include the primary synaptic mechanisms underlying excitation (mainly glutamate) and inhibition (mainly GABA). Our attention has focused on how the balance of excitation and inhibition regulates the timing, patterns, and extent of information flow across various circuits. A lot less is understood regarding second order processes that sculpt and modify these primary interactions. One such modulatory transmitter in the brain is acetylcholine (ACh). The importance of ACh in modulating various behaviors related to learning, memory, and attention has been recognized over the last four decades as has its involvement in various neurodegenerative and psychiatric disorders. However, our understanding of the mechanistic bases for these actions is at its infancy, at best and much remains to be understood. The array of receptor subtypes for nicotinic and muscarinic receptors, their different locations, and complex signal transduction mechanisms remain a puzzle. Transmitter (ACh) release sites and their relationship to receptor loci are poorly understood. Overall, we lack a unifying framework for conceptualizing how disparate actions of the transmitter on receptors lead to circuit modulation and, eventually, influences on cognition. By its very nature, reports on cholinergic signaling are quite scattered, presented in journals across sub-disciplines and in the context of the systems they modulate. Hence, there is need for consolidation of these studies under a single cover that would allow one to compare and contrast the effects of this transmitter across systems and contexts. This special issue represents one such compilation. The issue addresses cholinergic modulation of defined circuits that lead to specific behaviors and consists of a judicious mixture of review articles and primary papers. The articles focus on three aspects of the system: 1) Cellular targets of cholinergic signaling. 2) Receptor mechanisms. 3) Endogenous transmitter distribution and action. While no common mechanism emerges that can explain cholinergic actions on brain functions, on can postulate that the transmitter system is dynamic, modulating the balance of excitation and inhibition in various circuits. This modulation sets up timed network oscillations and it is tempting to speculate that these oscillations form a template for better encoding of afferent inputs. One can broadly envision the role of the cholinergic system as facilitating processes that allow for more efficient acquisition of learning and engraving of memories. Thus, understanding the mechanisms underlying tonic and stimulus-dependent release of ACh and how it alters firing templates of neuronal networks would be the first step towards elucidating its role in learning and memory. This special topics edition provides clues to some of the actions of ACh. It is hoped that the articles allow the reader to extract common themes and potential mechanisms of cholinergic regulation that will lead to elucidation of general principles governing the actions of this important neuromodulator.

Book Description
This open access book presents the roles and mechanisms of signal transduction triggered by nicotinic acetylcholine receptors (nAChRs) stimulation in neuroprotection against toxic effects of risk factors of neurodegenerative diseases. Accumulating evidence suggests that nAChRs in the CNS play important roles not only in excitatory neurotransmission but also in neuronal survival and related functions. Neuroprotection mediated by nAChRs in neurodegenerative diseases such as Alzheimer's disease is the major topic of this book. In response to rapidly evolving areas in clinical and laboratory neuropharmacology and neurochemistry, this volume provides in-depth coverage of neuroprotection in basic research and future developments in the clinical application of effective neuroprotective strategies in neurodegenerative diseases. This work appeals to both basic and clinical researchers in several fields, such as neuroscience, neurology, and pharmacology.

Book Description
Although serious interest in studying the role of central cho linergic processes in psychopathology is just beginning to emerge, experimental literature on the part played by cholinergic mechanisms in brain behavior. reiations is quite extensive. During the past thirty years, cholinergic research has contributed significantly to the characterization and differentiation of adaptive mechanisms in volved in input selection, perception, cortical, autonomic and behav ioral activation, learning, memory, and inhibitory control of behav ioral outputs. To say that dysfunction of one or more of these mech anisms may be at the root of neuropsychiatric illnesses such as schiz ophrenia would be stating the obvious. This book examines the part cholinergic processes might play in dysfunctions of the adaptive processes involved in higher brain func tions and their significance for the pathogenesis, classification, etiology, and treatment of psychopathological conditions. In a series of wide ranging reviews of the available information, the subject is discussed from a variety of perspectives, using data derived from both experimental and clinical research. The purpose is not so much to determine whether cholinergic excess or deficiency is causal in this or that neuropsychiatric syndrome, but rather to try to understand the disease mechanisms in terms of adaptive processes in which cholinergic systems seem to play an important part.
