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.

This issue dives into the study of sleep function, particularly as it relates to memory and cognition. Any clinician who sees patients with sleep disorders, or in particular any sleep medicine specialist, will find this information enlightening and invaluable, as it discusses the current state of understanding of how sleep affects humans' waking cognitive functions. These review articles describe the research that has taken place, and the lessons that can be taken away from them, so that clinicians can confidently advise their patients on the functional importance of adequate sleep, and recognize cognitive symptoms of inadequate sleep. Articles discuss such topics as animal and human research on sleep and memory, various imaging techniques to describe brain activity during sleep, and the role of dreams.

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"

Sleep has long been a topic of fascination for artists and scientists. Why do we sleep? What function does sleep serve? Why do we dream? What significance can we attach to our dreams?

We spend so much of our lives sleeping, yet its precise function is unclear, in spite of our increasing understanding of the processes generating and maintaining sleep. We now know that sleep can be accompanied by periods of intense cerebral activity, yet only recently has experimental data started to provide us with some insights into the type of processing taking place in the brain as we sleep. There is now strong evidence that sleep plays a crucial role in learning and in the consolidation of memories. Once the preserve of psychoanalysts, 'dreaming' is now a topic of increasing interest amongst scientists. With research into sleep growing, this volume is both timely and valuable in presenting a unique study of the relationship between sleep, learning, and memory. It brings together a team of international scientists researching sleep in both human and animal subjects. Aimed at researchers within the fields of neuroscience, cognitive neuroscience, psychiatry, and neurology, this book will be an important first step in developing a full scientific understanding of the most intriguing state of consciousness.
