Book Description
The principal purpose of this study was to investigate the possible differential effects of LSD as a function of procedural variations in performance of delayed response tasks. In general, LSD was found to impair delayed response performance in the monkey. From the standpoint of dose-effect relationships, the results suggest a positive correlation between magnitude of dose and extent of functional impairment. A tendency toward rapidly developing tolerance was observed. A 'placebo effect' in response to the control agent (sterile water) was encountered in a significant number of monkeys.

Book Description
Central Cholinergic Systems and behavior reviews experimental evidence on the possible involvement of central cholinergic systems in the regulation of animal behavior. More specifically, the book investigates the role of acetylcholine as a transmitter in the mammalian spinal cord and in central nervous function. This text also describes cholinergic involvement in some of the more fundamental processes of central nervous functions and how it may fit into overall cholinergic and non-cholinergic behavioral patterns. This book is organized into seven chapters and begins with an overview of the link between central cholinergic mechanisms and behavior, and then discusses the cholinergic roles in consciousness, emphasizing on the roles of reticular systems in the arousal mechanism. An effort is made to define the cholinergic nature of some spinal mechanisms that are apparently involved in reflexes and posture. An account of the role of cholinergic mechanisms in central respiratory control is also given, along with the function of acetylcholine as an important transmitter at many sites of the central nervous system. The book concludes by analyzing the roles of cholinergic systems in motivated behaviors, emotion, learning, and memory. This book is a valuable resource for students and researchers in fields ranging from physiology to biology and psychiatry.

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.

Book Description
Even if the “weapons of mass destruction” (WMD) and, among them, stocks of organoph- phorus (OP) agents (also referred to as war gases and nerve gases) were not found in Iraq following the US-Iraq war, the relative ease with which these substances can be made from harmless precursors and the low cost of their manufacture will continue to fascinate pow- hungry, ruthless dictators, as well as multinational and international terrorists, particularly as the close relationship between the OP agents and useful insecticides makes it easy to disguise the importation and purchase of small amounts of the precursors. Indeed, the use by Saddam Hussein of a nerve gas against the Kurds and his possible employment of the OP agents during his war with Iran, and the Sarin attack in the Tokyo underground by an extremist religious set magnetized the world with respect to the OP drugs. As these drugs exert their toxicity via their cholinergic action on the nervous, particularly central nervous, system, it is no wonder that the research in the cholinergic ? eld attracts, and merits, our intense attention. These considerations underlie the signi? cance of this book, as Alex Karczmar devotes an entire chapter of Exploring the Vertebrate Central Cholinergic Nervous System to anticholinest- ases (antiChEs), and as he is an acknowledged expert in the ? eld of cholinergic toxicity as well as a consultant to the Surgeon General of the U. S. Army.

Book Description
Caffeine in Food and Dietary Supplements is the summary of a workshop convened by the Institute of Medicine in August 2013 to review the available science on safe levels of caffeine consumption in foods, beverages, and dietary supplements and to identify data gaps. Scientists with expertise in food safety, nutrition, pharmacology, psychology, toxicology, and related disciplines; medical professionals with pediatric and adult patient experience in cardiology, neurology, and psychiatry; public health professionals; food industry representatives; regulatory experts; and consumer advocates discussed the safety of caffeine in food and dietary supplements, including, but not limited to, caffeinated beverage products, and identified data gaps. Caffeine, a central nervous stimulant, is arguably the most frequently ingested pharmacologically active substance in the world. Occurring naturally in more than 60 plants, including coffee beans, tea leaves, cola nuts and cocoa pods, caffeine has been part of innumerable cultures for centuries. But the caffeine-in-food landscape is changing. There are an array of new caffeine-containing energy products, from waffles to sunflower seeds, jelly beans to syrup, even bottled water, entering the marketplace. Years of scientific research have shown that moderate consumption by healthy adults of products containing naturally-occurring caffeine is not associated with adverse health effects. The changing caffeine landscape raises concerns about safety and whether any of these new products might be targeting populations not normally associated with caffeine consumption, namely children and adolescents, and whether caffeine poses a greater health risk to those populations than it does for healthy adults. This report delineates vulnerable populations who may be at risk from caffeine exposure; describes caffeine exposure and risk of cardiovascular and other health effects on vulnerable populations, including additive effects with other ingredients and effects related to pre-existing conditions; explores safe caffeine exposure levels for general and vulnerable populations; and identifies data gaps on caffeine stimulant effects.

Book Description
Catalyzed by the development of new neurobiological and behavioral techniques as well as new conceptual and theoretical approaches to the study of the relationship between brain and behavior, research exploring brain functions enabling learning and memory has greatly accelerated in recent years. The chapters in this book reflect current theoretical approaches to the study of brain and memory and provide new insights concerning the cellular bases of memory and the differential involvement of brain systems in different forms of memory. By presenting up-to-date summaries of research investigating brain mechanisms underlying learning and memory, these chapters help to place current findings in appropriate theoretical context, and further stimulate research inquiry attempting to understand how the brain makes memory. Divided into three sections, coverage in this volume includes: * a discussion of pharmacological approaches to the study of brain and memory; * a review of experiments using a variety of techniques, including brain lesions, brain grafting, and electrophysiological recording to investigate the role of different brain regions in learning and memory; and * an examination of molecular analyses of events associated with memory formation.

Book Description
The aim of this book is to summarize our understanding on the insect nicotinic acetylcholine receptors. This area of research received great impetus from the identification of the first subunit sequences to be used as neonicotinoid insecticide target sites. Although a book of this nature can provide the details only of commonly published results, it is hoped that it may provide a useful guide to the newcomer to the field as well as to point out some of the future challenges. For example, we need to determine the precise subunit nomenclature of insect nicotinic receptors. This nomenclature varies amongst species and this led to some of the early confusion that persists. We need to be precise in identifying the subunit composition of native insect nicotinic receptor subtypes, their functional properties and physiological roles.
