This book was released on 2013-11-11 with total page 592 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Food Components to Enhance Performance written by Institute of Medicine and published by National Academies Press. This book was released on 1994-02-01 with total page 560 pages. Available in PDF, EPUB and Kindle. Book excerpt: The physiological or psychological stresses that employees bring to their workplace affect not only their own performance but that of their co-workers and others. These stresses are often compounded by those of the job itself. Medical personnel, firefighters, police, and military personnel in combat settingsâ€"among othersâ€"experience highly unpredictable timing and types of stressors. This book reviews and comments on the performance-enhancing potential of specific food components. It reflects the views of military and non-military scientists from such fields as neuroscience, nutrition, physiology, various medical specialties, and performance psychology on the most up-to-date research available on physical and mental performance enhancement in stressful conditions. Although placed within the context of military tasks, the volume will have wide-reaching implications for individuals in any job setting.

Book excerpt: Abstract: Some neurological and psychiatric disorders of the brain associated with inadequate cholinergic transmission are being successfully treated with choline and/or lecithin. Plasma composition can affect neurotransmitter synthesis; one function of this phenomenon may be to provide metabolic signals to the brain concerning appetite, stimulus response, or sleepiness. The methods whereby this occurs are being investigated for their possible usefulness in treating manic depression, memory impairment and other brain disorders. Synthesis, biochemistry, measurement, metabolism and dietary sources of choline are discussed, as well as effects and side effects of treatment. Movement disorders, Huntington's disease, dyskinesia, learning and memory are among the brain functions affected by choline being investigated.

This book was released on 2013-03-13 with total page 867 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume represents a collection of papers which were contributed by participants at a Symposium for Cholinergic Mechanisms and Psycho pharmacology, held in La Jolla, California on March 28-30, 1977. The were chosen to emphasize areas in which there has been substantial topics progress in the past 2-3 years and fall into seven major groups dealingwith: cholinergiC receptors; chemistry, histochemistry and enzymology; cyclic nucleotides and cholinergiC mechanisms; storage, compartmentation and release of acetylcholine; regulatory mechanisms in acetylcholine metab olism; modulation of acetylcholine metabolism; and behavioral and clin ical manifestations of cholinergiC function and dysfunction. Each group contains one or more reviews and a number of shorter contributions de scribing current work. This symposium was the third in a series of which the first two were held in Skokloster, Sweden in 1970 and Boldern, Switzerland in 1974. The Proceedings of the meetings indicate a rapid development of knowledge of cholinergiC mechanisms which for many years lagged behind that of other neurotransmitters and neuroregulators. The inclusion of a large section in the present volume dealing with clinical manifestations of cholinergiC dysfunction reflects one of the most important trends in current research on cholinergiC mechanisms, namely the close inter-relationship and mutual support of basic science and clinical investigation. I hope that this volume will be of value to all those whose work relates to cholinergiC function, at both basic and clinicalleve18, and will continue to stimulate the vigorous exchange of ideas which was such a prominent feature of the Symposium.

Download or read book Brain Cholinergic Mechanisms written by Sukumar Vijayaraghavan and published by Frontiers Media SA. This book was released on 2016-01-22 with total page 129 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: This book incorporates the proceedings of the Fifth International Cholinergic Conference, which took place in Oglebay Park, West Vir ginia, USA, on October 30th to November 4th, 1983. A scenic forty five minute ride from the City of Pittsburgh, surrounded by champion ship golf courses, luxurious woods and a picturesque lake, Oglebay provided relaxed and beautiful surroundings, conducive to contem plation, stimulating discussions and, thought-provoking scientific sessions. Over 160 individuals from allover the world participated in the sessions. The meeting was sub-divided into oral presentations, round table discussions and poster sessions, and centered upon ten key topics of cholinergic relevance (see Table of Contents). Following in the tradition of the four International Conferences which had preceded this one, the Conference featured the most up to-date developments in the area of cholinergic mechanisms, and provided for ample and productive discussion of new fields and di rections in this area. Moreover, both senior investigators in the field as well as recent newcomers to this sphere of investigation participated in the proceedings. This book, touches on a wide array of mechanisms and applications - from the preclinical to the clinical level. It should thus be useful as a comprehensive resource, with the cholinergic system as a focal hub. The Conference could not have been as successful as it turned out to be, without the support of a number of important contributors.

This book was released on 2012-12-06 with total page 544 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book The Cholinergic Synapse written by Victor P. Whittaker and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 766 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the most impressive works of scholarship in the field of experimental pharmacology has been the Heffter-Heubner Handbuch der experimentellen Pharmakologie, internationalized some years ago under the title Handbook 0/ Experimental Pharmacology and kept up to date by a series of numbered Ergiin zungswerke or supplementary volumes which have now replaced in importance the original Handbuch. These volumes constitute a valuable and continuously up dated multi author review series of topics important in modern pharmacology and allied sciences. The Editorial Board of the Handbook invited me 2 years ago to undertake, as subeditor, the preparation of a new volume entitled The Cholinergic Synapse. A previous volume in this series, vol. 15, Cholinesterases and Anticholinesterase Agents, edited by GEORGE KOELLE, was published in 1963 and was far wider in scope than its title suggested: it was, in fact an authoritative summing up of the whole subject of cholinergic function and still has some value today as an account of the state of the art as it was at that time. Since then another excellent review, of a specific cholinergic synapse, has appeared in this series: this was vol. 42, Neuromuscular Junction, edited by ELEANOR ZAIMIS and published in 1976. A third volume, vol. 53, Pharmacology o/Ganglionic Transmission, which appeared in 1980 and was edited by D. A. KHARKEVICH, includes important aspects of autonomic cholinergic function.

Available in PDF, EPUB and Kindle. Book excerpt: The brain is the most complex organ in our body. Indeed, it is perhaps the most complex structure we have ever encountered in nature. Both structurally and functionally, there are many peculiarities that differentiate the brain from all other organs. The brain is our connection to the world around us and by governing nervous system and higher function, any disturbance induces severe neurological and psychiatric disorders that can have a devastating effect on quality of life. Our understanding of the physiology and biochemistry of the brain has improved dramatically in the last two decades. In particular, the critical role of cations, including magnesium, has become evident, even if incompletely understood at a mechanistic level. The exact role and regulation of magnesium, in particular, remains elusive, largely because intracellular levels are so difficult to routinely quantify. Nonetheless, the importance of magnesium to normal central nervous system activity is self-evident given the complicated homeostatic mechanisms that maintain the concentration of this cation within strict limits essential for normal physiology and metabolism. There is also considerable accumulating evidence to suggest alterations to some brain functions in both normal and pathological conditions may be linked to alterations in local magnesium concentration. This book, containing chapters written by some of the foremost experts in the field of magnesium research, brings together the latest in experimental and clinical magnesium research as it relates to the central nervous system. It offers a complete and updated view of magnesiums involvement in central nervous system function and in so doing, brings together two main pillars of contemporary neuroscience research, namely providing an explanation for the molecular mechanisms involved in brain function, and emphasizing the connections between the molecular changes and behavior. It is the untiring efforts of those magnesium researchers who have dedicated their lives to unraveling the mysteries of magnesiums role in biological systems that has inspired the collation of this volume of work.
