The Neuroscience Of Sleep And Dreams

The Neuroscience of Sleep and Dreams provides comprehensive coverage of the basic neuroscience of both sleep and dreams for upper-level undergraduate and graduate students. It details new scientific discoveries, places those discoveries within evolutionary context, and links established findings with implications for sleep medicine. This second edition focuses on recent developments in the social nature of sleep and dreams. Coverage includes the neuroscience of all stages of sleep; the lifespan development of these sleep stages; the role of non-REM and REM sleep in health and mental health; comparative sleep; biological rhythms; sleep disorders; sleep memory; dream content; dream phenomenology, and dream functions. Students, scientists, and interested non-specialists will find this book accessible and informative.

"Sleep is one of the most important but least understood aspects of our life, wellness, and longevity ... An explosion of scientific discoveries in the last twenty years has shed new light on this fundamental aspect of our lives. Now ... neuroscientist and sleep expert Matthew Walker gives us a new understanding of the vital importance of sleep and dreaming"--Amazon.com.

Sleep is the natural state of bodily rest, common to all mammals and birds and also seen in many reptiles, amphibians and fish. For most species, regular sleep is essential for survival, yet the specific purposes of sleep are still only partly clear and are the subject of intense research. This volume is comprised of the editors’ selection of the most relevant articles on sleep from the Encyclopedia of Neuroscience, resulting in the first comprehensive collection of introductory articles on the neuroscience of sleep. Articles explore sleep’s impact on neural functioning, sleep disorders, the relation between sleep and other clinical disorders, a look at sleep from a developmental perspective, and more. * Chapters offer impressive scope with topics addressing neural functioning, disorders, development, and more, carefully selected by one of the most preeminent sleep researchers * Richly illustrated in full color with over 100 figures * Contributors represent the most outstanding scholarship in the field, with each chapter providing fully vetted and reliable expert knowledge

"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.

A renowned neurologist shares the true stories of people unable to get a good night’s rest in The Nocturnal Brain: Nightmares, Neuroscience, and the Secret World of Sleep, a fascinating exploration of the symptoms and syndromes behind sleep disorders. For Dr. Guy Leschziner’s patients, there is no rest for the weary in mind and body. Insomnia, narcolepsy, night terrors, apnea, and sleepwalking are just a sampling of conditions afflicting sufferers who cannot sleep—and their experiences in trying are the stuff of nightmares. Demoniac hallucinations frighten people into paralysis. Restless legs rock both the sleepless and their sleeping partners with unpredictable and uncontrollable kicking. Out-of-sync circadian rhythms confuse the natural body clock’s days and nights. Then there are the extreme cases. A woman in a state of deep sleep who gets dressed, unlocks her car, and drives for several miles before returning to bed. The man who has spent decades cleaning out kitchens while “sleep-eating.” The teenager prone to the serious, yet unfortunately nicknamed Sleeping Beauty Syndrome stuck in a cycle of excessive unconsciousness, binge eating, and uncharacteristic displays of aggression and hypersexuality while awake. With compassionate stories of his patients and their conditions, Dr. Leschziner illustrates the neuroscience behind our sleeping minds, revealing the many biological and psychological factors necessary in getting the rest that will not only maintain our physical and mental health, but improve our cognitive abilities and overall happiness.

Jouvet tells the story of a handful of neurobiologists, including himself, who pioneered sleep and dream research in the 1950s.

Designed primarily as a text this volume is an up-to-date and integrated overview of physiological sleep mechanisms, brain function, psychological ramifications of sleep, dimensions of dreaming, and clinical disorders associated with sleep. It is accessibly written with specially boxed material that enhances the text. Authored by a researcher/clinician/professor with more than 25 years of experience in sleep studies, Understanding Sleep and Dreaming provides a solid basis for those who are not expert in this area. It offers a good foundation for those who will continue sleep studies, while at the same time offering enough information for those who will apply this knowledge in other ways such as clinicians in their individual practices or researchers for whom sleep may be part of a specific study. It is an excellent text for courses on sleep at the undergraduate and graduate levels.

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.
