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

open access: yesPLoS 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

open access: yesFrontiers 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

The Biology of REM Sleep [PDF]

open access: yesCurrent Biology, 2017
Considerable advances in our understanding of the mechanisms and functions of rapid-eye-movement (REM) sleep have occurred over the past decade. Much of this progress can be attributed to the development of new neuroscience tools that have enabled high-precision interrogation of brain circuitry linked with REM sleep control, in turn revealing how REM ...

Methods for REM Sleep Density Analysis: A Scoping Review

open access: yesClocks & 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

Overview of Idiopathic REM Sleep Behavior Disorder [PDF]

open access: yes, 2022
REM sleep behavior disorder (RBD) is a REM sleep-related parasomnia characterized by action of dream content, which is often an aggressive or terrible nightmare.

A cluster of mesopontine GABAergic neurons suppresses REM sleep and curbs cataplexy

open access: yesCell 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.

Circadian and ultradian NREM-REM sleep modulation of dream recall : effects of age and spectral activity [PDF]

open access: yes, 2011
This thesis deals with the electrophysiological correlates of sleep prior to dream recall and the age-related effects on dream processing. The dual NREM/REM sleep cycle and the circadian modulation of REM sleep sum to generate dream processing.

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

open access: yesFrontiers 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.

open access: yesPLoS 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 ...

REM sleep homeostasis in the absence of REM sleep: Effects of antidepressants

open access: yesNeuropharmacology, 2016
Most antidepressants suppress rapid eye movement (REM) sleep, which is thought to be important to brain function, yet the resulting REM sleep restriction is well tolerated. This study investigated the impact of antidepressants with different mechanisms of action, such as selective serotonin reuptake inhibitors (SSRIs) and tricyclic antidepressants (TCA)
