A Hypothalamic Switch for REM and Non-REM Sleep [PDF]

Neuron, 2018
Rapid eye movement (REM) and non-REM (NREM) sleep are controlled by specific neuronal circuits. Here we show that galanin-expressing GABAergic neurons in the dorsomedial hypothalamus (DMH) comprise separate subpopulations with opposing effects on REM versus NREM sleep.

Chronic insomnia, REM sleep instability and emotional dysregulation: A pathway to anxiety and depression? [PDF]

J Sleep Res
Summary The world‐wide prevalence of insomnia disorder reaches up to 10% of the adult population. Women are more often afflicted than men, and insomnia disorder is a risk factor for somatic and mental illness, especially depression and anxiety disorders.

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.

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

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

, 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 ...

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

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.

REM Sleep EEG Instability in REM Sleep Behavior Disorder and Clonazepam Effects [PDF]

Sleep, 2017
We aimed to analyze quantitatively rapid eye movement (REM) sleep electroencephalogram (EEG) in controls, drug-naïve idiopathic REM sleep behavior disorder patients (iRBD), and iRBD patients treated with clonazepam.Twenty-nine drug-naïve iRBD patients (mean age 68.2 years), 14 iRBD patients under chronic clonazepam therapy (mean age 66.3 years), and 21

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 ...
