Sleep Medicine Reviews, 2012
The development of sleep research can be divided into two main periods. The first one was initiated in 1863 by the first systematic measurement of the depth of sleep, the second in 1953 by the discovery of recurrent episodes of rapid eye movements in sleep.

Neurologic Clinics, 1996
The three states of mammalian being--wakefulness, REM sleep, and NREM sleep--are not mutually exclusive and may occur simultaneously, oscillate rapidly, or appear in dissociated or incomplete form to produce primary sleep parasomnias. Dysfunctions of a wide variety of organ systems may take advantage of the sleeping state to declare themselves ...

Consciousness and Cognition, 2012
To test whether mental activities collected from non-REM sleep are influenced by REM sleep, we suppressed REM sleep using clomipramine 50mg (an antidepressant) or placebo in the evening, in a double blind cross-over design, in 11 healthy young men. Subjects were awakened every hour and asked about their mental activity.

Neuroscience & Biobehavioral Reviews, 2000
Elements of three old, overlapping theories of REM sleep (REM) function, the Ontogenetic, Homeostatic and Phylogenetic hypotheses, together still provide a plausible framework - that REM (i) is directed towards early cortical development, (ii) "tones up" the sleeping cortex, (iii) can substitute for wakefulness, (iv) has a calming effect.

Publisher Summary This chapter focuses on sleep behavior disorder (RBD). Rapid eye movement (REM) sleep parasomnias are disorders in which undesirable physical phenomena occur predominantly during REM sleep. REM parasomnias encompass abnormal sleep-related movements, behavior, emotions, and dreaming.

Parkinsonism & Related Disorders, 2016
Rapid Eye Movement (REM) sleep Behaviour Disorder (RBD) is a REM sleep parasomnia characterized by loss of the muscle atonia that typically occurs during REM sleep, therefore allowing patients to act out their dreams. RBD manifests itself clinically as a violent behaviour occurring during the night, and is detected at the polysomnography by phasic and ...

Breakdown in REM sleep circuitry underlies REM sleep behavior disorder
Trends in Neurosciences, 2014During rapid eye movement (REM) sleep, skeletal muscles are almost paralyzed. However, in REM sleep behavior disorder (RBD), which is a rare neurological condition, muscle atonia is lost, leaving afflicted individuals free to enact their dreams. Although this may sound innocuous, it is not, given that patients with RBD often injure themselves or their ...

Dissociative symptoms and REM sleep
Behavioral and Brain Sciences, 2013AbstractLlewellyn has written a fascinating article about rapid eye movement (REM) dreams and how they promote the elaborative encoding of recent memories. The main message of her article is that hyperassociative and fluid cognitive processes during REM dreaming facilitate consolidation.

Publisher Summary This chapter focuses on the cellular and neurophysiological/neuropharmacological, with most of the emphasis on mechanisms relevant to rapid eye movement (REM) sleep. The chapter presents the sleep architecture and phylogeny/ontogeny so as to provide a basis for the later mechanistic discussions.

Most studies of sleep have been conducted in humans, with lesser numbers in "standard" laboratory animals such as the rat, rabbit and dog. Relatively few studies have been conducted of the more than 4000 other mammalian species. However, those studies that have been undertaken clearly show that REM sleep amounts vary enormously across the animal ...
