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

open access: yes, 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

open access: yesMedical 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,

Dynamic BOLD functional connectivity in humans and its electrophysiological correlates [PDF]

open access: yes, 2012
Neural oscillations subserve many human perceptual and cognitive operations. Accordingly, brain functional connectivity is not static in time, but fluctuates dynamically following the synchronization and desynchronization of neural populations.

Oscillatory EEG activity during REM sleep in elderly people predicts subsequent dream recall after awakenings [PDF]

open access: yes, 2019
Several findings underlined that the electrophysiological (EEG) background of the last segment of sleep before awakenings may predict the presence/absence of dream recall (DR) in young subjects.

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

open access: yesFrontiers 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

Hypocretins, sleep, and maternal behavior

open access: yesFrontiers in Behavioral Neuroscience, 2023
The postpartum period is a demanding time during which mothers experience numerous physiological adaptations that enable them to care for their offspring while maintaining their wellbeing. Hypocretins, also known as orexins, are neuropeptides synthesized

Research progress of the paraventricular thalamus in the regulation of sleep–wake and emotional behaviors

open access: yesIbrain, 2022
The paraventricular thalamus (PVT) is a major component of the midline structure of the thalamus. It is one of the nonspecific nuclei of the thalamus, which plays a great role in the regulation of cortical arousal.
