REM sleep deprivation during 5 hours leads to an immediate REM sleep rebound and to suppression of non-REM sleep intensity [PDF]

open access: yesElectroencephalography and Clinical Neurophysiology, 1990
Nine healthy male subjects were deprived of REM sleep during the first 5 h after sleep onset. Afterwards recovery sleep was undisturbed. During the deprivation period the non-REM EEG power spectrum was reduced when compared to baseline for the ...

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 Parasomnias

Neurologic Clinics, 1996
This article focuses primarily on REM sleep behavior disorder, a recently identified syndrome with a corresponding animal model. Diagnostic methods and criteria, treatment, and the world literature are reviewed, and the experience of the authors' institution--The Minnesota Regional Sleep Disorders Center (Minneapolis, MN)--is summarized.

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 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 behaviour disorder

Nature Reviews Disease Primers, 2018
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.

Restless REM Sleep Impedes Overnight Amygdala Adaptation [PDF]

open access: yesCurrent Biology, 2019
Animal studies show that insufficient silencing of the locus coeruleus (LC) during REM sleep impairs sleep-related brain plasticity. Restless REM sleep, a characteristic of several psychiatric disorders, likely reflects insufficient LC silencing.

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.
