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 electroencephalogram (EEG) during waking. We investigated the association of sleepiness and awake EEG spectra during 40 h of wakefulness using multi-electrode EEG recordings for full coverage of the scalp. We found: (1). strong negative correlations of alpha (8-12 Hz) power with subjective sleepiness at all… Expand
Theta activity in the waking EEG is a marker of sleep propensity in the rat
TLDR
In rats, as in humans, a specific waking EEG frequency, i.e., theta power in quiet waking is a marker of sleep propensity, which reflects the rise in sleep propensity. Expand
Global field synchronization reveals rapid eye movement sleep as most synchronized brain state in the human EEG
TLDR
A surprising finding of higher synchrony during REM sleep challenges the view ofREM sleep as a desynchronized brain state and may provide insight into the function of REM sleep. Expand
Slow eye movements and subjective estimates of sleepiness predict EEG power changes during sleep deprivation.
TLDR
Individual and group analyses converged in indicating that slow eye movements can be considered reliable indexes of sleepiness but only in the eyes-closed condition, and suggest that subjective and EEG changes associated with higher sleepiness are paralleled by an increase in slow eye movement activity. Expand
Going local: insights from EEG and stereo-EEG studies of the human sleep-wake cycle.
TLDR
A large body of evidence is reviewed, mainly from quantitative EEG studies of the laboratory, support for the notion that sleep is a local and use-dependent process, and stereo-EEG recordings clearly indicate that sleep and wakefulness can co-exist in different areas, suggesting that vigilance states are not necessarily temporally discrete states. Expand
Functional EEG topography in sleep and waking: State-dependent and state-independent features
TLDR
The frequency-specific clustering of power maps suggests that distinct generators underlie EEG frequency bands and that basic topographic features appear to be state-independent. Expand
Beta EEG reflects sensory processing in active wakefulness and homeostatic sleep drive in quiet wakefulness
TLDR
Electroencephalogram dynamics were measured in epochs of active wake or quiet wake, finding that Quiet wake, particularly when characterized by beta activity, is permissive to metabolic and electrophysiological changes that occur in slow‐wave sleep. Expand
The EEG indicators of the dynamic properties of sleep–wake regulating processes: comparison of the changes occurring across wake–sleep transition with the effects of prolonged wakefulness
Everyday oscillations between wakefulness and sleep might be ultimately delineated as cyclic alternations between opposing neurobiological processes, i.e. those promoting arousal and inhibiting sleepExpand
Can we feel like being neither alert nor sleepy? The electroencephalographic signature of this subjective sub-state of wake state yields an accurate measure of objective sleepiness level.
TLDR
It is recommended that implementation of the proposed objective measure into experimental procedures requiring accurate estimation of objective sleepiness level is implemented. Expand
Electroencephalographic activity during wakefulness, rapid eye movement and non-rapid eye movement sleep in humans: Comparison of their circadian and homeostatic modulation
Electroencephalographic (EEG) activity is a key indicator of a vigilance state, and quantitative analyses of the EEG have revealed profound differences both between and within vigilance states inExpand
Theta waves in children’s waking electroencephalogram resemble local aspects of sleep during wakefulness
TLDR
Results indicate that widespread theta events measured on the scalp might be markers of local sleep in humans, and seem to be related to the well described performance decline under high sleep pressure. Expand

TLDR
It is suggested that theta activity in waking and slow-wave activity in sleep are markers of a common homeostatic sleep process. Expand
Frontal predominance of a relative increase in sleep delta and theta EEG activity after sleep loss in humans.
TLDR
The data demonstrate that the enhancement of slow wave EEG activity during sleep following extended wakefulness is most pronounced in frontal cortical areas. Expand

TLDR
The results support the notion that ambulatory EEG/EOG changes may be used to quantify sleepiness and suggest physiological changes due to sleepiness are not likely to occur until extreme sleepiness is encountered. Expand
Neural basis of alertness and cognitive performance impairments during sleepiness. I. Effects of 24 h of sleep deprivation on waking human regional brain activity
TLDR
Evidence is provided that short‐term sleep deprivation produces global decreases in brain activity, with larger reductions in activity in the distributed cortico‐thalamic network mediating attention and higher‐order cognitive processes, and is complementary to studies demonstrating deactivation of these cortical regions during NREM and REM sleep. Expand

TLDR
The present findings support the hypothesis that the EEG power density in the low frequency range is an indicator of a progressively declining process during sleep whose initial value is determined by the duration of prior waking. Expand

TLDR
Analyses of the (nonadditive) interaction of the circadian and sleep-dependent components of sleep propensity and sleep structure revealed that the phase relation between the sleep-wake cycle and the circadian pacemaker during entrainment promotes the consolidation of sleep and wakefulness and facilitates the transitions between these vigilance states. Expand
Two circadian rhythms in the human electroencephalogram during wakefulness.
TLDR
It is concluded that the waking EEG undergoes changes that can be attributed to circadian and homeostatic processes and may represent electrophysiological correlates of different aspects of the circadian rhythm in arousal. Expand

TLDR
The data support the hypothesis that EEG power density during non-rapid eye movement sleep is only determined by the prior history of sleep and wakefulness and is not determined by clock-like mechanisms. Expand

Separation of circadian and wake duration-dependent modulation of EEG activation during wakefulness
TLDR
The data imply that the circadian pacemaker facilitates frontal EEG activation during the wake maintenance zone, by generating an arousal signal that prevents the intrusion of low-frequency EEG components, the propensity for which increases progressively during wakefulness. Expand
