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.

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

Validation of non-REM sleep stage decoding from resting state fMRI using linear support vector machines [PDF]

open access: yes, 2016
A growing body of literature suggests that changes in consciousness are reflected in specific connectivity patterns of the brain as obtained from resting state fMRI (rs-fMRI). As simultaneous electroencephalography (EEG) is often unavailable, decoding of

Slow Wave Sleep and Long Duration Spaceflight [PDF]

open access: yes, 2012
While ground research has clearly shown that preserving adequate quantities of sleep is essential for optimal health and performance, changes in the progression, order and /or duration of specific stages of sleep is also associated with deleterious ...

Sleep apnea detection with SMS notification [PDF]

open access: yes, 2020
Sleeping is a process in which the body and mind is in recurring state. Sleeping is not only affecting human health but also can affect body mass index (BMI) and metabolic regulation of a person [1].

Effects of Some H1-Antagonists on the Sleep-Wake Cycle in Sleep-Disturbed Rats

open access: yesJournal of Pharmacological Sciences, 2007
The present study was undertaken to investigate the effects of some H1-antagonists on the sleep-wake cycle in sleep-disturbed rats in comparison with those of nitrazepam.

Network Physiology reveals relations between network topology and physiological function

open access: yes, 2012
The human organism is an integrated network where complex physiologic systems, each with its own regulatory mechanisms, continuously interact, and where failure of one system can trigger a breakdown of the entire network.

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 ...
