REM sleep promotes experience-dependent dendritic spine elimination in the mouse cortex
Nature Communications, 2020 In many parts of the nervous system, experience-dependent refinement of neuronal circuits predominantly involves synapse elimination. The role of sleep in this process remains unknown.

Methods for REM Sleep Density Analysis: A Scoping Review
Clocks & Sleep, 2023 Rapid eye movements (REM) sleep density is the parameter proposed to explain the variability in the amount of eye movements during REM sleep. Alterations in REM sleep density have been proposed as a screening criterion for individuals with depression and

Complementary contributions of NREM and REM sleep to visual learning
Nature Neuroscience, 2020 Sleep is beneficial for learning. However, it remains unclear whether learning is facilitated by non-rapid eye movement (NREM) sleep or by REM sleep, whether it results from plasticity increases or stabilization, and whether facilitation results from ...

A cluster of mesopontine GABAergic neurons suppresses REM sleep and curbs cataplexy
Cell Discovery, 2022 Physiological rapid eye movement (REM) sleep termination is vital for initiating non-REM (NREM) sleep or arousal, whereas the suppression of excessive REM sleep is promising in treating narcolepsy.

Differential Effects of Psychological and Physical Stress on the Sleep Pattern in Rats [PDF]
, 2007 In the present study, we investigated the acute effects of 2 different kinds of stress, namely physical stress (foot shock) and psychological stress (non-foot shock) induced by the communication box method, on the sleep patterns of rats.

Coupled flip-flop model for REM sleep regulation in the rat.
PLoS ONE, 2014 Recent experimental studies investigating the neuronal regulation of rapid eye movement (REM) sleep have identified mutually inhibitory synaptic projections among REM sleep-promoting (REM-on) and REM sleep-inhibiting (REM-off) neuronal populations that ...

Sleep architecture when sleeping at an unusual circadian time and associations with insulin sensitivity. [PDF]
PLoS ONE, 2013 Circadian misalignment affects total sleep time, but it may also affect sleep architecture. The objectives of this study were to examine intra-individual effects of circadian misalignment on sleep architecture and inter-individual relationships between ...

The primary function of REM sleep [PDF]
, 2006 In this paper, the physiological features associated with the different stages of REM sleep and with what information processing researchers have called “effort” and “arousal” are compared.

REM Sleep Characteristics in Narcolepsy and REM Sleep Behavior Disorder [PDF]
Sleep, 2007 To assess the presence of polysomnographic characteristics of REM sleep behavior disorder (RBD) in narcolepsy; and to quantify REM sleep parameters in patients with narcolepsy, in patients with "idiopathic" RBD, and in normal controls.Sleep laboratory studySixteen patients with narcolepsy and cataplexy matched for age and sex with 16 patients with ...
