Characteristic Effects of Anti-dementia Drugs on Rat Sleep Patterns

open access: yesJournal of Pharmacological Sciences, 2009
The present study was undertaken to clarify the effects of anti-dementia drugs on sleep pattern in rats. Electrodes were chronically implanted into the frontal cortex and the dorsal neck muscle of rats for the electroencephalogram (EEG) and ...

REM sleep in narcolepsy

open access: yesSleep Medicine Reviews
Narcolepsy is mainly associated with excessive daytime sleepiness, but the characteristic feature is abnormal rapid eye movement (REM) sleep phenomena. REM sleep disturbances can manifest as cataplexy (in narcolepsy type 1), sleep paralysis, sleep-related hallucinations, REM sleep behavior disorder, abnormal dreams, polysomnographic evidence of REM ...

Neural circuitry of rapid eye movement sleep homeostasis: Mechanistic insights and pathological implications

open access: yesSleep Research
Rapid eye movement (REM) sleep is a unique brain state crucial for emotion, memory, and plasticity. Unlike well‐understood non‐REM (NREM) sleep homeostasis, REM sleep homeostasis remains less clearly defined.

Melanin-concentrating hormone neurons contribute to dysregulation of rapid eye movement sleep in narcolepsy

open access: yesNeurobiology of Disease, 2018
The lateral hypothalamus contains neurons producing orexins that promote wakefulness and suppress REM sleep as well as neurons producing melanin-concentrating hormone (MCH) that likely promote REM sleep.

A high-density electroencephalography study reveals abnormal sleep homeostasis in patients with rapid eye movement sleep behavior disorder

open access: yesScientific Reports, 2021
Rapid eye movement (REM) sleep behavior disorder (RBD) is characterized by disrupting motor enactments during REM sleep, but also cognitive impairments across several domains.

REM sleep and neurodegeneration

open access: yesJournal of Sleep Research
SummarySeveral brainstem, subcortical and cortical areas are involved in the generation of rapid eye movement (REM) sleep. The alteration of these structures as a result of a neurodegenerative process may therefore lead to REM sleep anomalies.

Automated scoring of pre-REM sleep in mice with deep learning

open access: yesScientific Reports, 2021
Reliable automation of the labor-intensive manual task of scoring animal sleep can facilitate the analysis of long-term sleep studies. In recent years, deep-learning-based systems, which learn optimal features from the data, increased scoring accuracies ...

Wilson?s disease presenting as rapid eye movement sleep behavior disorder: a possible window to early treatment

open access: yesArquivos de Neuro-Psiquiatria, 2014
Objective To describe characteristics of REM sleep behavior disorder in Wilson’s disease. Method Questionnaire-based interviews (patients and relatives), neurological examinations, two-week prospective dream-diary, video-polysomnography, transcranial ...

Targeted dream incubation at sleep onset can influence later dream content in REM sleep: a pilot study

open access: yesFrontiers in Sleep
Targeted dream incubation (TDI) is a highly effective method for eliciting hypnagogic dreams related to specific topics through the presentation of verbal prompts and serial awakenings at sleep onset.
