Modeling circadian and sleep-homeostatic effects on short-term interval timing [PDF]

, 2015
Short-term interval timing i.e., perception and action relating to durations in the seconds range, has been suggested to display time-of-day as well as wake dependent fluctuations due to circadian and sleep-homeostatic changes to the rate at which an ...

Hypothalamic GABAergic neurocircuitry in the regulation of energy homeostasis and sleep/wake control

Medical Review, 2022
Gamma-aminobutyric acid (GABAergic) neuron, as one of important cell types in synaptic transmission, has been widely involved in central nervous system (CNS) regulation of organismal physiologies including cognition, emotion, arousal and reward. However,

The Effects of Mild Disturbances on Sleep Behaviour in Laying Hens

Animals, 2023
The positive welfare of commercial animals presents many benefits, making the accurate assessment of welfare important. Assessments frequently use behaviour to determine welfare state; however, nighttime behaviours are often ignored.

REM sleep deprivation during 5 hours leads to an immediate REM sleep rebound and to suppression of non-REM sleep intensity [PDF]

, 1990
Nine healthy male subjects were deprived of REM sleep during the first 5 h after sleep onset. Afterwards recovery sleep was undisturbed. During the deprivation period the non-REM EEG power spectrum was reduced when compared to baseline for the ...

Sleep-wake patterns and sleep quality in urban Georgia

Translational Neuroscience, 2016
Sleep problems represent a worldwide health concern but their prevalence and impacts are unknown in most non-European/North American countries. This study aimed to evaluate sleep-wake patterns, sleep quality and potential correlates of poor sleep in a ...

Detecting Brain Activity Following a Verbal Command in Patients With Disorders of Consciousness

Frontiers in Neuroscience, 2019
BackgroundThe accurate assessment of patients with disorders of consciousness (DOC) is a challenge to most experienced clinicians. As a potential clinical tool, functional magnetic resonance imaging (fMRI) could detect residual awareness without the need

Adenosine Downregulates the Activities of Glutamatergic Neurons in the Paraventricular Hypothalamic Nucleus Required for Sleep

Frontiers in Neuroscience, 2022
Adenosine is an endogenous substance that regulates sleep homeostasis. It plays an important role in sleep induction under physiological condition. So far, the neural mechanisms underlying sleep-promoting effects of adenosine are not completely clear ...

Arousal State-Dependent Alterations in Neural Activity in the Zebra Finch VTA/SNc

Frontiers in Neuroscience, 2020
Sleep-wake behaviors are important for survival and highly conserved among animal species. A growing body of evidence indicates that the midbrain dopaminergic system is associated with sleep-wake regulation in mammals.

Dysfunctions of the paraventricular hypothalamic nucleus induce hypersomnia in mice

eLife, 2021
Hypersomnolence disorder (HD) is characterized by excessive sleep, which is a common sequela following stroke, infection, or tumorigenesis. HD is traditionally thought to be associated with lesions of wake-promoting nuclei.
