Subjective sleepiness is part of the system controlling the decision to go to sleep in humans.
Extended periods of waking lead to increased sleepiness, as well as to changes in cortical …

Abstract Study Objectives: Although daytime complaints are a defining characteristic of
insomnia, most EEG studies evaluated sleep only. We used high-density …

We used the waking electroencephalogram to study the homeostatic sleep regulatory
process in human short sleepers and long sleepers. After sleeping according to their …

To investigate the relationship between markers of sleep homeostasis during waking and
sleep, the electroencephalogram of eight young males was recorded intermittently during a …

Our earlier research has shown considerable increases of and intercorrelations between
subjective sleepiness, alpha, theta, and delta power density of the EEG as well as slow …

The impact of sleep deprivation (high sleep pressure) vs sleep satiation (low sleep pressure)
on waking EEG dynamics, subjective sleepiness and core body temperature (CBT) was …

Sleep inertia (SI) denotes a period of hypovigilance, confusion and impaired cognitive and
behavioral performance that immediately follows awakening. Based on the observation that …

Abstract Study Objectives To examine nonrapid eye movement (NREM) sleep in insomnia
using high-density electroencephalography (EEG). Methods All-night sleep recordings with …

Homeostatic and circadian processes are basic mechanisms of human sleep which
challenge the common knowledge of large individual variations in sleep need or differences …

Eight subjects were kept awake and active overnight in a sleep lab isolated from
environmental time cues. Ambulatory EEG and EOG were continuously recorded and …
