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.

Available in PDF, EPUB and Kindle. Book excerpt: MICHAEL S. GAZZANIGA The investigation of the human brain and mind involves a myriad of ap proaches. Cognitive neuroscience has grown out of the appreciation that these approaches have common goals that are separate from other goals in the neural sciences. By identifying cognition as the construct of interest, cognitive neuro science limits the scope of investigation to higher mental functions, while simultaneously tackling the greatest complexity of creation, the human mind. The chapters of this collection have their common thread in cognitive neuroscience. They attack the major cognitive processes using functional stud ies in humans. Indeed, functional measures of human sensation, perception, and cognition are the keystone of much of the neuroscience of cognitive sci ence, and event-related potentials (ERPs) represent a methodological "coming of age" in the study of the intricate temporal characteristics of cognition. Moreover, as the field of cognitive ERPs has matured, the very nature of physiology has undergone a significant revolution. It is no longer sufficient to describe the physiology of non-human primates; one must consider also the detailed knowledge of human brain function and cognition that is now available from functional studies in humans-including the electrophysiological studies in humans described here. Together with functional imaging of the human brain via positron emission tomography (PET) and functional magnetic resonance imaging (fMRI), ERPs fill our quiver with the arrows required to pierce more than the single neuron, but the networks of cognition.
Download or read book Zen and the Brain written by James H. Austin and published by MIT Press. This book was released on 1999-06-04 with total page 876 pages. Available in PDF, EPUB and Kindle. Book excerpt: A neuroscientist and Zen practitioner interweaves the latest research on the brain with his personal narrative of Zen. Aldous Huxley called humankind's basic trend toward spiritual growth the "perennial philosophy." In the view of James Austin, the trend implies a "perennial psychophysiology"—because awakening, or enlightenment, occurs only when the human brain undergoes substantial changes. What are the peak experiences of enlightenment? How could these states profoundly enhance, and yet simplify, the workings of the brain? Zen and the Brain presents the latest evidence. In this book Zen Buddhism becomes the opening wedge for an extraordinarily wide-ranging exploration of consciousness. In order to understand which brain mechanisms produce Zen states, one needs some understanding of the anatomy, physiology, and chemistry of the brain. Austin, both a neurologist and a Zen practitioner, interweaves the most recent brain research with the personal narrative of his Zen experiences. The science is both inclusive and rigorous; the Zen sections are clear and evocative. Along the way, Austin examines such topics as similar states in other disciplines and religions, sleep and dreams, mental illness, consciousness-altering drugs, and the social consequences of the advanced stage of ongoing enlightenment.

Download or read book Use of Services for Family Planning and Infertility United States 1982 written by Gerry E. Hendershot and published by . This book was released on 1988 with total page 982 pages. Available in PDF, EPUB and Kindle. Book excerpt: The 1982 statistics on the use of family planning and infertility services presented in this report are preliminary results from Cycle III of the National Survey of Family Growth (NSFG), conducted by the National Center for Health Statistics. Data were collected through personal interviews with a multistage area probability sample of 7969 women aged 15-44. A detailed series of questions was asked to obtain relatively complete estimates of the extent and type of family planning services received. Statistics on family planning services are limited to women who were able to conceive 3 years before the interview date. Overall, 79% of currently mrried nonsterile women reported using some type of family planning service during the previous 3 years. There were no statistically significant differences between white (79%), black (75%) or Hispanic (77%) wives, or between the 2 income groups. The 1982 survey questions were more comprehensive than those of earlier cycles of the survey. The annual rate of visits for family planning services in 1982 was 1077 visits /1000 women. Teenagers had the highest annual visit rate (1581/1000) of any age group for all sources of family planning services combined. Visit rates declined sharply with age from 1447 at ages 15-24 to 479 at ages 35-44. Similar declines with age also were found in the visit rates for white and black women separately. Nevertheless, the annual visit rate for black women (1334/1000) was significantly higher than that for white women (1033). The highest overall visit rate was for black women 15-19 years of age (1867/1000). Nearly 2/3 of all family planning visits were to private medical sources. Teenagers of all races had higher family planning service visit rates to clinics than to private medical sources, as did black women age 15-24. White women age 20 and older had higher visit rates to private medical services than to clinics. Never married women had higher visit rates to clinics than currently or formerly married women. Data were also collected in 1982 on use of medical services for infertility by women who had difficulty in conceiving or carrying a pregnancy to term. About 1 million ever married women had 1 or more infertility visits in the 12 months before the interview. During the 3 years before interview, about 1.9 million women had infertility visits. For all ever married women, as well as for white and black women separately, infertility services were more likely to be secured from private medical sources than from clinics. The survey design, reliability of the estimates and the terms used are explained in the technical notes.

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.

Available in PDF, EPUB and Kindle. Book excerpt: The relationship between resources and development is the pivot around which the present study revolves. Focussing on the process of resource creation and utilization it emphasizes the need of equitable development integrating local needs, resources, people and functions. The resource exploitation and their utilization are two independent economic activities influenced by different algorithms and usually have manifested in core-periphery relationship. Reviews the persistent problems of economic development in perspective of exploitation of natural resources with the objective to provide some clues for occurrence and persistence of regional disparities and for suggesting a development model synchronising both the resource management and environmental protection.
