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 ...

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.

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 ...

Rapid eye movement (REM) sleep behaviour disorder (RBD) is a parasomnia that is characterized by loss of muscle atonia during REM sleep (known as REM sleep without atonia, or RSWA) and abnormal behaviours occurring during REM sleep, often as dream enactments that can cause injury.

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.

Clinical Neurophysiology, 2000
REM sleep is the stage associated with vivid dream mentation, desynchronous cortical EEG, and atonia of antigravitary muscles. REM sleep behavior disorder (RBD) is characterized by the intermittent loss of REM sleep atonia and by the appearance of elaborate motor activity associated with dream mentation.

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 ...

Melatonin and Maturation of Rem Sleep
International Journal of Neuroscience, 1992The discovery in 1953 of rapid eye movement (REM) sleep and the appreciation that sleep is a heterogeneous physiological state stimulated major research into sleep disorders. Electroencephalographic studies have shown that the amount of REM sleep changes with age.
