Despite impressive advances in understanding sleep as a biological phenomenon and in understanding the nature of mental processes in the normal waking state, our knowledge of mental life during sleep remains extremely impoverished. The common identification of cognition with consciousness leaves the impression that little or no mental activity occurs during sleep. The present volume represents the Proceedings of the Arizona Conference on Sleep and Cognition, held in Tucson January 19-22, 1989. A principal concern of the conference was the implications of recent work on implicit memory and other aspects of information-processing outside of awareness for studies of cognitive processes during sleep, and the role of the sleep laboratory as a vehicle for studying various aspects of information processing outside of awareness, in the absence of the active deployment of attention. To this end, selected investigators in the area of sleep who have an interest in cognitive processes were brought together with their counterparts in the area of cognition who have an interest in sleep. We hope that one outcome of this meeting, and publication of the Proceedings, will be a new agenda for research on sleep that will carry investigators of both camps well into the 21st century.

Human Sleep and Cognition

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.

The cognitive and behavioral implications of sleep deprivation have been noted in the medical literature for many years. In addition, emerging research continues to demonstrate the contribution of sleep deprivation to some of the most common and costly health conditions today. Sleep Deprivation and Disease provides clinically relevant scientific information to help clinicians, public health professionals, and researchers recognize the ramifications of sleep deprivation across a broad spectrum of health topics. This timely reference covers sleep physiology, experimental approaches to sleep deprivation and measurement of its consequences, as well as health and operational consequences of sleep deprivation. Clinical challenges and areas of uncertainty are also presented in order to encourage future advancements in sleep medicine and help patients avoid the outcomes associated with the myriad causes of sleep deprivation.

This book reviews current knowledge on the importance of sleep for brain function, from molecular mechanisms to behavioral output, with special emphasis on the question of how sleep and sleep loss ultimately affect cognition and mood. It provides an extensive overview of the latest insights in the role of sleep in regulating gene expression, synaptic plasticity and neurogenesis and how that in turn is linked to learning and memory processes. In addition, readers will learn about the potential clinical implications of insufficient sleep and discover how chronically restricted or disrupted sleep may contribute to age-related cognitive decline and the development of psychiatric disorders such as schizophrenia and depression. The book consists of 19 chapters, written by experts in basic sleep research and sleep medicine, which together cover a wide range of topics on the importance of sleep and consequences of sleep disruption. This book will be of interest to students, researchers and clinicians with a general interest in brain function or a specific interest in sleep.

The orexin system, discovered in 1998, has emerged as a crucial player in regulating the sleep and wake balance inside our brain. This discovery has sparked a burst of novel and dynamic research on the physiology and pathology of sleep. The Orexin System: Basic Science and Role in Sleep Pathology honors this research and the authors share their ideas and perspectives on the novel developments within the field. The book examines the intricate role of the orexin system in regulating sleep and wake, and its interaction with other wake-regulating systems. The orexin system is dissected at the cellular and molecular level to explore the diversity of the orexin-producing neurons, their projections, and their signaling pathways. Additionally, the book discusses the diseases which are associated with a dysfunctional orexin system, such as narcolepsy, insomnia, substance abuse, and Alzheimer’s disease, and explores the new potential therapeutic applications derived from the burst of research around this fascinating system. This publication is essential reading for neurobiologists, neurologists, psychopharmacologists, sleep researchers, and other researchers and clinical scientists interested in sleep, sleep research, insomnia, and medicine in general.

Provides a critical review of stimulant medication literature regarding stimulant efficacy for restoring/maintaining cognition during sleep loss.

Clinical practice related to sleep problems and sleep disorders has been expanding rapidly in the last few years, but scientific research is not keeping pace. Sleep apnea, insomnia, and restless legs syndrome are three examples of very common disorders for which we have little biological information. This new book cuts across a variety of medical disciplines such as neurology, pulmonology, pediatrics, internal medicine, psychiatry, psychology, otolaryngology, and nursing, as well as other medical practices with an interest in the management of sleep pathology. This area of research is not limited to very young and old patientsâ€"sleep disorders reach across all ages and ethnicities. Sleep Disorders and Sleep Deprivation presents a structured analysis that explores the following: Improving awareness among the general public and health care professionals. Increasing investment in interdisciplinary somnology and sleep medicine research training and mentoring activities. Validating and developing new and existing technologies for diagnosis and treatment. This book will be of interest to those looking to learn more about the enormous public health burden of sleep disorders and sleep deprivation and the strikingly limited capacity of the health care enterprise to identify and treat the majority of individuals suffering from sleep problems.

"A truly comprehensive, scientifically rigorous and utterly fascinating account of when, how, and why we dream. Put simply, When Brains Dream is the essential guide to dreaming." —Matthew Walker, author of Why We Sleep Questions on the origins and meaning of dreams are as old as humankind, and as confounding and exciting today as when nineteenth-century scientists first attempted to unravel them. Why do we dream? Do dreams hold psychological meaning or are they merely the reflection of random brain activity? What purpose do dreams serve? When Brains Dream addresses these core questions about dreams while illuminating the most up-to-date science in the field. Written by two world-renowned sleep and dream researchers, it debunks common myths that we only dream in REM sleep, for example—while acknowledging the mysteries that persist around both the science and experience of dreaming. Antonio Zadra and Robert Stickgold bring together state-of-the-art neuroscientific ideas and findings to propose a new and innovative model of dream function called NEXTUP—Network Exploration to Understand Possibilities. By detailing this model’s workings, they help readers understand key features of several types of dreams, from prophetic dreams to nightmares and lucid dreams. When Brains Dream reveals recent discoveries about the sleeping brain and the many ways in which dreams are psychologically, and neurologically, meaningful experiences; explores a host of dream-related disorders; and explains how dreams can facilitate creativity and be a source of personal insight. Making an eloquent and engaging case for why the human brain needs to dream, When Brains Dream offers compelling answers to age-old questions about the mysteries of sleep.

Each issue, guest edited by a leader in the field of sleep medicine, provides expert, state-of-the-art reviews on a single topic, making ample use of figures, diagrams, and tables in a two-colour format.
