Sleep-wake sensitive mechanisms of adenosine release in the basal forebrain of rodents : an in vitro study [PDF]
, 2013 Adenosine acting in the basal forebrain is a key mediator of sleep homeostasis. Extracellular adenosine concentrations increase during wakefulness, especially during prolonged wakefulness and lead to increased sleep pressure and subsequent rebound sleep.

Cortical excitability signatures for the degree of sleepiness in human
eLife, 2021 Sleep is essential in maintaining physiological homeostasis in the brain. While the underlying mechanism is not fully understood, a ‘synaptic homeostasis’ theory has been proposed that synapses continue to strengthen during awake and undergo downscaling ...

Characterization of aEEG During Sleep and Wakefulness in Healthy Children
Frontiers in Pediatrics, 2022 IntroductionInterpretation of amplitude-integrated EEG (aEEG) is hindered by lacking knowledge on physiological background patterns in children. The aim of this study was to find out whether aEEG differs between wakefulness and sleep in children ...

The spatiotemporal pattern of the human electroencephalogram at sleep onset after a period of prolonged wakefulness [PDF]
, 2019 During the sleep onset (SO) process, the human electroencephalogram (EEG) is characterized by an orchestrated pattern of spatiotemporal changes. Sleep deprivation (SD) strongly affects both wake and sleep EEG, but a description of the topographical EEG ...
