Differential Effects of Psychological and Physical Stress on the Sleep Pattern in Rats [PDF]

, 2007
In the present study, we investigated the acute effects of 2 different kinds of stress, namely physical stress (foot shock) and psychological stress (non-foot shock) induced by the communication box method, on the sleep patterns of rats.

Four‐Year Follow‐up of [18F]Fluorodeoxyglucose Positron Emission Tomography–Based Parkinson's Disease–Related Pattern Expression in 20 Patients with Isolated Rapid Eye Movement Sleep Behavior Disorder Shows Prodromal Progression

Movement Disorders, 2020
Isolated rapid eye movement sleep behavior disorder is known to be prodromal for alpha‐synucleinopathies, such as Parkinson's disease (PD) and dementia with Lewy bodies.

Newly detected rapid eye movement associated sleep apnea after coronavirus disease 2019 as a possible cause for chronic fatigue: two case reports

Journal of Medical Case Reports, 2021
Background Coronavirus disease 2019 has become a health problem spreading worldwide with pandemic characteristics since March 2020. Post coronavirus disease 2019 symptoms are more frequent than initially expected, with fatigue as an often-mentioned issue.

Sawtooth waves during REM sleep after administration of haloperidol combined with total sleep deprivation in healthy young subjects [PDF]

, 2002
We sought to examine the possible participation of dopaminergic receptors in the phasic events that occur during rapid eye movement (REM) sleep, known as sawtooth waves (STW).

Regional Delta Waves In Human Rapid Eye Movement Sleep

Journal of Neuroscience, 2019
Although the EEG slow wave of sleep is typically considered to be a hallmark of nonrapid eye movement (NREM) sleep, recent work in mice has shown that slow waves can also occur in REM sleep. Here, we investigated the presence and cortical distribution of

A role for spindles in the onset of rapid eye movement sleep

Nature Communications, 2020
Sleep spindle generation classically relies on an interplay between the thalamic reticular nucleus (TRN), thalamo-cortical (TC) relay cells and cortico-thalamic (CT) feedback during non-rapid eye movement (NREM) sleep.

Non-rapid eye movement sleep with low muscle tone as a marker of rapid eye movement sleep regulation

BMC Neuroscience, 2006
Background It was recently reported that epochs of non-REM sleep (NREMS) with low muscle tone represent a partial correlate of REM sleep (REMS). To further investigate this phenomenon, episodes of restricted night-time sleep (23:00 – 03.00h) and ...

Effect of colostrum feeding method and presence of dam on the sleep, rest and sucking behaviour of newborn calves [PDF]

, 2008
"In rats, sucking milk reduces anxiety and promotes non-rapid eye movement (NREM) sleep, and in calves it induces resting but the effect on sleep is unknown. Here, we investigated how calves' sleep was affected by colostrum feeding methods.

Automated analysis of connected speech reveals early biomarkers of Parkinson’s disease in patients with rapid eye movement sleep behaviour disorder

Scientific Reports, 2017
For generations, the evaluation of speech abnormalities in neurodegenerative disorders such as Parkinson’s disease (PD) has been limited to perceptual tests or user-controlled laboratory analysis based upon rather small samples of human vocalizations ...

Current ideas about the roles of rapid eye movement and non–rapid eye movement sleep in brain development

Acta paediatrica, 2020
Understanding the links between sleep and brain development is important, as rapid eye movement (REM) sleep and non‐REM (NREM) sleep seem to contribute to different aspects of brain maturation.
