REM sleep, REM parasomnias, REM sleep behaviour disorder

Ideggyógyászati szemle, 2022
We review the literature on REM parasomnias, and their the underlying mechanisms. Several REM parasomnias are consistent with sleep dissociations, where certain elements of the REM sleep pattern emerge in an inadequate time (sleep paralysis, hypnagogic hallucinations and cataplexy) or are absent/partial in their normal REM sleep time (REM sleep without

REM sleep and memory

Current Opinion in Neurobiology, 2017
Memory consolidation, a process which stabilizes recently acquired information into long-term storage, is thought to be optimized during sleep. Although recent evidence indicates that non-rapid-eye movement sleep (NREMs) is directly involved in memory consolidation, the role of rapid-eye movement sleep (REMs) in this process has remained controversial ...

REM-sleep timing is controlled homeostatically by accumulation of REM-sleep propensity in non-REM sleep

American Journal of Physiology-Regulatory, Integrative and Comparative Physiology, 1994
Sleep structure in the rat was characterized during uninterrupted full-day recordings using an analytic procedure that identifies rapid eye movement (REM) sleep episodes based on REM-sleep-onset electroencephalograph phenomena, hence independently of REM-sleep duration.

REM Sleep Parasomnias

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 ...

Forerunners of REM sleep

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.

Dreaming without REM sleep

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.

REM sleep Behaviour Disorder

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 ...
