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

Scientific 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

A predictive propensity measure to enter REM sleep

Frontiers 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 ...

Is REM Density a Measure of Arousal during Sleep?

Brain 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

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

, 2017
We aimed to analyze quantitatively REM sleep EEG in controls, drug-naïve idiopathic REM sleep behavior disorder patients (iRBD), and iRBD patients treated with ...

Homeostatic regulation of NREM sleep, but not REM sleep, in Australian magpies

, 2022
Study Objectives We explore non-rapid eye movement (NREM) and rapid eye movement (REM) sleep homeostasis in Australian magpies (Cracticus tibicen tyrannica).

Ostriches sleep like platypuses.

PLoS ONE, 2011
Mammals and birds engage in two distinct states of sleep, slow wave sleep (SWS) and rapid eye movement (REM) sleep. SWS is characterized by slow, high amplitude brain waves, while REM sleep is characterized by fast, low amplitude waves, known as ...

Single‐channel EEG classification of sleep stages based on REM microstructure

Healthcare Technology Letters, 2021
Rapid‐eye movement (REM) sleep, or paradoxical sleep, accounts for 20–25% of total night‐time sleep in healthy adults and may be related, in pathological cases, to parasomnias.

A Study on REM Sleep Homeostasis in the Day-Active Tree Shrew (Tupaia belangeri): Cold-Induced Suppression of REM Sleep Is Not Followed by a Rebound

Biology, 2023
The function and regulation of rapid-eye-movement (REM) sleep is a topic of ongoing debate. It is often assumed that REM sleep is a homeostatically regulated process and that a need for REM sleep builds up, either during prior wakefulness or during ...

What is REM sleep? [PDF]

, 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 ...

Melanin-concentrating hormone (MCH): a new sleep factor?

Frontiers in Neurology, 2011
Neurons that utilize the neuropeptide melanin-concentrating hormone (MCH) as a neuromodulator are mainly located in the lateral hypothalamus and the incerto-hypothalamic area, and have widespread projections throughout the brain.
