Assessing REM Sleep as a Biomarker for Depression Using Consumer Wearables [PDF]

Diagnostics
Background: Rapid-eye-movement (REM) sleep disinhibition—shorter REM latency and a larger nightly REM fraction—is a well-described laboratory correlate of major depression.

An Asymmetrical Hypothesis for the NREM-REM Sleep Alternation—What Is the NREM-REM Cycle?

Frontiers in Neuroscience, 2021
Since the discovery of rapid eye movement (REM) sleep (Aserinsky and Kleitman, 1953), sleep has been described as a succession of cycles of non-REM (NREM) and REM sleep episodes.

A probabilistic model for the ultradian timing of REM sleep in mice.

PLoS Computational Biology, 2021
A salient feature of mammalian sleep is the alternation between rapid eye movement (REM) and non-REM (NREM) sleep. However, how these two sleep stages influence each other and thereby regulate the timing of REM sleep episodes is still largely unresolved.

Role of corticosterone on sleep homeostasis induced by REM sleep deprivation in rats. [PDF]

PLoS ONE, 2013
Sleep is regulated by humoral and homeostatic processes. If on one hand chronic elevation of stress hormones impair sleep, on the other hand, rapid eye movement (REM) sleep deprivation induces elevation of glucocorticoids and time of REM sleep during the

Increased Rapid Eye Movement Sleep Is Associated With a Reduced Risk of Heart Failure in Middle-Aged and Older Adults

Frontiers in Cardiovascular Medicine, 2022
ObjectivesRapid eye movement (REM) sleep is closely related to all-cause mortality. The aim of this study is to explore the role of REM sleep on the incident heart failure (HF).MethodsWe selected 4490 participants (2480 women and 2010 men; mean age, 63.2

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

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.

Molecular Mechanisms of REM Sleep

Frontiers in Neuroscience, 2020
Rapid-eye movement (REM) sleep is a paradoxical sleep state characterized by brain activity similar to wakefulness, rapid-eye-movement, and lack of muscle tone.

A moderate increase of physiological CO2 in a critical range during stable NREM sleep episode: A potential gateway to REM sleep

Frontiers in Neurology, 2012
Sleep is characterized as rapid eye movement (REM) and non-rapid eye movement (NREM) sleep. Studies suggest that wake-related neurons in the basal forebrain, posterior hypothalamus and brainstem and NREM sleep-related neurons in the anterior-hypothalamic

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 ...
