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 ...

Decoding Wakefulness Levels from Typical fMRI Resting-State Data Reveals Reliable Drifts between Wakefulness and Sleep [PDF]

, 2014
SummaryThe mining of huge databases of resting-state brain activity recordings represents state of the art in the assessment of endogenous neuronal activity—and may be a promising tool in the search for functional biomarkers.

A non-symmetric Gaussian wake model for lateral wake-to-wake interactions

Journal of Physics: Conference Series, 2023
Abstract In this paper, we propose a new non-symmetric Gaussian wake model, which allows for different lateral expansions on the two sides of a wake to account for its interaction with neighbouring wakes. The proposed model is formulated following classical speed-deficit assumptions and momentum conservation.

EEG correlation and power during maintenance of wakefulness test after sleep-deprivation [PDF]

, 2011
To investigate whether there are any objective EEG characteristics that change significantly between specific time periods during maintenance of wakefulness test (MWT) and whether such changes are associated with the ability to appropriately communicate ...

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.

The Neural Correlates of Consciousness: A Spectral Exponent Approach to Diagnosing Disorders of Consciousness

Brain Sciences
Background/Objectives: Disorder of consciousness (DoC) poses diagnostic challenges due to behavioral assessment limitations. This study evaluates the spectral exponent (SE)—a neurophysiological biomarker quantifying the decay slope of ...
