Book Description
This book discusses the evolution of sleep and its possible function in the higher invertebrates and vertebrates, including humans. It describes the current concept of sleep and its functions, based on research on the mammalian system. To date, electrophysiological recordings of the brain waves, muscle activity, and eye movements are the only tools available for characterizing the sleep architecture in the majority of animals. In mammals and birds, only two distinct types of sleep are found – non-rapid eye movement (NREM) and rapid eye movement (REM) sleep. Since the discovery of REM sleep, studies have been performed to understand the purpose of the two distinct sleep states in higher vertebrates (birds and mammals), and how REM sleep was evolved. The book summarizes the role of both REM and NREM sleep in the proper functioning of the brain and body. It covers various aspects of the role of sleep in important physiological processes, including memory consolidation, induction of synaptic plasticity, energy restoration, enhancing immune response, and maturation of neuronal circuitries during early life. Lastly, the book reviews the effects of chronic/acute sleep deprivation on memory consolidation, obesity, and the immune system in animal models and humans.

Book Description
J ÜRGEN AscHOFF "Very bad habit! Very bad habit!" Captain Giles to Joseph Conrad who had taken a siesta. -Conrad: The Shadow Line On the Multiplicity of Rest-Activity Cycles: Some Historical and Conceptual Notes According to its title this book tries to answer the profound question of why we nap-and why Captain Giles was wrong in blaming Conrad for having napped. However, in this volume the term nap is not used in the narrower sense of an afternoon siesta; instead, emphasis is placed on the recurrent alternation between states of alertness and drowsiness, i. e. , on rest-activity cycles of high er frequency throughout the 24 hr. In view of this focus, two authors (Stampi, in Chapter I, and Ball, in Chapter 3) rightly refer to the psychologist Szymanski who was among the first to describe "polyphasic" activity patterns. Hence, I consider it appropriate to open this foreword with a few historical remarks. At the time when Szymanski (1920) made the distinction between "monophasic" and "polyphasic" rest-activity patterns and sleep-wake cy cles, respectively, not much was known about the mechanisms of such temporal structures. Although the botanists quite some time ago had demonstrated the endogenous nature of the "monophasic" sleep movements in plants, the hypothesis of an (still unknown) external driving force was favored by those who studied rhythms in animals and humans (Aschoff, 1990).

Book Description
Foundations of Sleep Health presents sleep health as a critical element of overall individual and population health. Sleep disorders are an increasing problem plaguing more than 40 million Americans. Sleep impacts numerous biological functions and plays a critical role in brain development, including learning and memory consolidation, cognitive functioning, and emotion regulation. This book provides an historic and current overview of the state of sleep health with an emphasis on the interplay between several levels of determinants and factors that influence sleep health. The text provides students in the health professions with in-depth discussion on the theory, research, and practice of sleep health, while also detailing mechanisms, hypotheses, and determinants of sleep and ways to improve sleep health. - Discusses the current state of knowledge of sleep health, research into the factors that contribute to and are impacted by sleep health - Uses a socioecological model to examine the whole range of determinants of sleep health, from biological to upstream environmental factors and possible modes of intervention - Contains a detailed glossary of sleep health terms to aid in the understanding of key concepts - Includes learning outcomes for each chapter, objective assessments of knowledge, with explanations, and open-ended questions designed to facilitate discussion

Book Description
Over the years there has been growing interest among the scientific community in investigating sleep and how it affects the memory and other brain functions. It is now well established that sleep helps in memory consolidation and induction of neural plasticity, and that short-term deprivation of either total sleep or rapid eye movement sleep alone can induce memory deficits very quickly. Quantitative and qualitative changes in sleep architecture after different training tasks further suggest that discrete memory types may require specific sleep stage/s for optimal memory consolidation, and studies indicate that sleep deprivation alters synaptic plasticity and membrane excitability in the hippocampal neurons and synaptic up-scaling in the cortical neurons. Further, sleep alteration during pregnancy may increase the risk of depression and adversely affect maternal-child relationships, parenting practices, family functioning, and children's development and general wellbeing. This book coherently discusses all these aspects, with a particular focus on the possible role of sleep in memory consolidation and synaptic plasticity. It also highlights the detrimental effects of sleep loss on mental health, the immune system and cognition. This book is a valuable reference resource for students and researchers working in the area of sleep, memory, or neuronal plasticity.

Book Description
What, if anything, do dreams tell us about ourselves? What is the relationship between types of sleep and types of dreams? Does dreaming serve any purpose? Or are dreams simply meaningless mental noise--"unmusical fingers wandering over the piano keys"? With expertise in philosophy, psychology, and neuroscience, Owen Flanagan is uniquely qualified to answer these questions. And in Dreaming Souls he provides both an accessible survey of the latest research on sleep and dreams and a compelling new theory about the nature and function of dreaming. Flanagan argues that while sleep has a clear biological function and adaptive value, dreams are merely side effects, "free riders," irrelevant from an evolutionary point of view. But dreams are hardly unimportant. Indeed, Flanagan argues that dreams are self-expressive, the result of our need to find or to create meaning, even when we're sleeping. Rejecting Freud's theory of manifest and latent content--of repressed wishes appearing in disguised form--Flanagan shows how brainstem activity during sleep generates a jumbled profusion of memories, images, thoughts, emotions, and desires, which the cerebral cortex then attempts to shape into a more or less coherent story. Such dream-narratives range from the relatively mundane worries of non REM sleep to the fantastic confabulations of deep REM that resemble psychotic episodes in their strangeness. But however bizarre these narratives may be, they can shed light on our mental life, our well being, and our sense of self. Written with clarity, lively wit, and remarkable insight, Dreaming Souls offers a fascinating new way of apprehending one of the oldest mysteries of mental life.

Book Description
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.

Book Description
Originally published in 1979, this book provides students with an example of the ways in which an evolutionary perspective can rephrase and clarify traditional questions and issues in psychology. The format provides the student firstly with the minimal amount of basic information in neuroanatomy, genetics and modern evolutionary theory in a form which is readily related to the remainder of the volume. The book then goes on to consider the relationships between different forms of explanation in biology, and the role of brain behaviour students in these relationships. Finally, the reader is given an opportunity to follow the reasoning which stems from a biological approach when applied to topics in human behaviour such as learning, dreaming, sleeping, exploration, anxiety, reasoning, intelligence and consciousness. Modern evolutionary biology places man in a broader context than does traditional psychology, and this new perspective reduces our tendency to view life solely from a human standpoint. The significance as well as the uniqueness of some traditionally ‘human’ attributes are challenged by this approach.
