Available in PDF, EPUB and Kindle. Book excerpt: This experiment investigated the effects of 3 concentrations (15%, 25% and 35%) of nitrous oxide (N2O) on reaction time (RT) and P300 latency and amplitude. Ten subjects responded to visually presented male or female names in an oddball paradigm with accuracy controlled at a high level. The results were analysed on a single-trial basis. Nitrous oxide increased both RT and P300 latency is a dose-related manner and these variables showed a strong between-dose correlation (r=0.67). Nitrous oxide also decreased P300 amplitude but only up to the 25% dose. The between-dose correlation for P300 amplitude and RT was negligible (r=-0.14). These results suggest that P300 latency is an index of N2O narcosis and are interpreted as indicating that narcosis involves the slowing of stimulates evaluation processes.

Download or read book Diving Science Revisited written by Michael B. Strauss and published by Best Publishing. This book was released on 2023-02-01 with total page 455 pages. Available in PDF, EPUB and Kindle. Book excerpt: Diving Science...Revisited is like no other diving text, including its predecessor, Diving Science. Amplified with figures, tables, and photos in color, this book includes four unique and innovative parts amplified by nine contributors. - Medical problems of diving (MPD) are discussed from stimulus-response perspectives in the phase of a dive in which they are likely to occur. - MPD are explained by how they affect the human diver whether physical, physiological, psychological, and/or lack of awareness. - A variety of diving types and situations from breath-hold to rebreather, from children to women to older aged adults, from cold water to cave, and from deep altitude to diving with handicaps are described in individual chapters with their merits, hazards, and necessary precautions for safe diving. - Part IV contains a concise summary of the MPD from seven different perspectives ranging from the significance of the problem to when to return to diving. - Part V consists of a rhetorical question for each of the first four parts with bullet points that recap the subjects covered in each chapter. This book describes the positive as well as undesirable ways divers' interact with the aquatic environment. It is especially recommended for the following: -Diving instructors and supervisors - Those involved with clinical applications of hyperbaric oxygen therapy - Those engaged in diving-associated marine biology and underwater missions - All divers, whether novice or advanced, who want to advance their knowledge about the science and medical challenges of diving.

Download or read book The Effects of Hypoxia on P300 and Reaction Time written by B. Fowler and published by . This book was released on 1988 with total page 7 pages. Available in PDF, EPUB and Kindle. Book excerpt: This experiment investigated the effects of three levels of arterial oxyhemoglobin saturation (SaO2 of 75%, 70% and 65%) on reaction time (RT) and p300 latency and amplitude. Ten subjects responded to visually presented male or female names in an oddball paradigm with accuracy controlled at a high level. Hypoxia increased both RT and p300 latency in a dose-related manner and these variables were strongly correlated. Hypoxia did not influence p300 amplitude. The increase in p300 latency is interpreted as further evidence that hypoxia slows stimulus evaluation processes and that, under the right circumstances, p300 could be used to index the effects of hypoxia on performance. Reaction time (RT) is the traditional measure for assessing the timing of cognitive stages of information processing but it is an end product and therefore includes the time to evaluate a stimulus, choose a response and organize it. It has recently been proposed that RT could be supplemented by p300 as a means for distinguishing between stages of processing (2,3). p300 is a positive going, endogenous, event related brain potential (ERP), occurring within the period 300 to 600 ms after the stimulus.

Download or read book Risk Assessment for Neurobehavioral Toxicity written by Bernard Weiss and published by DIANE Publishing. This book was released on 1997-07 with total page 258 pages. Available in PDF, EPUB and Kindle. Book excerpt: After three decades of research, neurobehavioral toxicity is now acknowledged as a significant outcome of chemical exposure. Its health and economic costs may exceed those by cancer by substantial amounts. This new perspective has been accompanied by efforts designed to explore the responsible mechanisms, to design applicable risk assessment procedures, and to determine the consequent policy implications. This publication includes 25 papers from international experts and includes: human neurobehavioral toxicity; animal behavioral methods; selected model compounds; and risk assessment.

Book excerpt: Synapse, Neuron, Brain, the third and last volume in the series Medical Physics, focuses on neurons and their interactions. Comprised of seven chapters regarding the brain's synapses and nerves, this volume concludes through the presentation of medical physics and its applications. An introductory chapter of this volume provides the necessary basic concepts and theories needed in the understanding of the book. This is followed by a discussion on the brain and its interconnections with the spinal cord. Chapter 3 focuses on the importance of evoked potentials as a diagnostic tool for the sensory organ and the neural processing of the stimuli. Chemical and electrical properties of synapses are also given emphasis. Other topics covered in this volume include the rall theory and neuronal integration; membrane noise at synaptic junctions; and new techniques on brain studies (autoradiography, positron annihilation, and nuclear magnetic resonance). As with the other volumes, this also caters to persons in various disciplines such as medicine, physiology, physics, and biology.

Download or read book Handbook of Military Psychology written by Reuven Gal and published by John Wiley & Sons. This book was released on 1991 with total page 822 pages. Available in PDF, EPUB and Kindle. Book excerpt: The military must evaluate large numbers of people, screen out the unfit, select individuals with needed abilities, and place people in the jobs most appropriate both to their skills and to military needs. Military personnel, of all sorts, must be trained and prepared for warfare. Individuals have to be led and motivated and units must maintain high morale and cohesion in order to achieve their missions. Furthermore, military missions are frequently carried out under most stressful conditions and usually require strenuous adjustment between human capabilities and weapon-systems' peculiarities. These characteristics of military organization all have their psychological aspects. This comprehensive handbook will be an essential tool for military psychologists, trainers and leaders dealing with these aspects. It will also be of interest to both practitioners and researchers working in the field of occupational and industrial psychology, and for those working in personnel management.
