Rapid eye movements during sleep in mice: High trait-like stability qualifies rapid eye movement density for characterization of phenotypic variation in sleep patterns of rodents

open access: yesBMC Neuroscience, 2011
Background In humans, rapid eye movements (REM) density during REM sleep plays a prominent role in psychiatric diseases. Especially in depression, an increased REM density is a vulnerability marker for depression.

Evaluating the evidence surrounding pontine cholinergic involvement in REM sleep generation

open access: yesFrontiers in Neurology, 2015
Rapid eye movement (REM) sleep - characterized by vivid dreaming, motor paralysis, and heightened neural activity - is one of the fundamental states of the mammalian central nervous system.

Comparative Perspectives that Challenge Brain Warming as the Primary Function of REM Sleep

open access: yesiScience, 2020
Summary: Rapid eye movement (REM) sleep is a paradoxical state of wake-like brain activity occurring after non-REM (NREM) sleep in mammals and birds.

Sleep architecture when sleeping at an unusual circadian time and associations with insulin sensitivity. [PDF]

open access: yesPLoS 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 ...

What Is REM Sleep? [PDF]

open access: yesCurrent Biology, 2020
For many decades, sleep researchers have sought to determine which species ‘have’ rapid eye movement (REM) sleep. In doing so, they relied predominantly on a template derived from the expression of REM sleep in the adults of a small number of mammalian species.

REM Sleep and Endothermy: Potential Sites and Mechanism of a Reciprocal Interference

open access: yesFrontiers in Physiology, 2017
Numerous data show a reciprocal interaction between REM sleep and thermoregulation. During REM sleep, the function of thermoregulation appears to be impaired; from the other hand, the tonic activation of thermogenesis, such as during cold exposure ...

Evening light environments can be designed to consolidate and increase the duration of REM-sleep

open access: yesScientific Reports, 2022
Evening exposure to short-wavelength light has disruptive effects on circadian rhythms and sleep. These effects can be mitigated by blocking short-wavelength (blue) frequencies, which has led to the development of evening blue-depleted light environments

Clinical characteristics of insomnia in perimenopausal women: a clinical study based on polysomnography

open access: yesDi-san junyi daxue xuebao, 2021
Objective To investigate the clinical characteristics and influencing factors of insomnia in perimenopausal women based on polysomnography (PSG). Methods A total of 52 perimenopausal women admitted to our psychological clinic due to insomnia were ...

Is REM Density a Measure of Arousal during Sleep?

open access: yesBrain Sciences, 2023
Rapid eye movements (REMs), an expression of REM sleep phasic activity, occur against a stable background of cortical desynchronization and the absence of axial tone. The significance of REMs during the sleep period was initially attributed to the mental

A predictive propensity measure to enter REM sleep

open access: yesFrontiers in Neuroscience
IntroductionDuring sleep periods, most mammals alternate multiple times between rapid-eye-movement (REM) sleep and non-REM (NREM) sleep. A common theory proposes that these transitions are governed by an “hourglass-like” homeostatic need to enter REM ...
