Sleep homeostasis and models of sleep regulation.
According to the two-process model of sleep regulation, the timing and structure of sleep are determined by the interaction of a homeostatic and a circadian process. The original qualitative modelExpand

Low-frequency (<1Hz) oscillations in the human sleep electroencephalogram
Low-frequency (< 1 Hz) oscillations in intracellular recordings from cortical neurons were first reported in the anaesthetized cat and then also during natural sleep. The slow sequences ofExpand

Electromagnetic fields, such as those from mobile phones, alter regional cerebral blood flow and sleep and waking EEG
Usage of mobile phones is rapidly increasing, but there is limited data on the possible effects of electromagnetic field (EMF) exposure on brain physiology. We investigated the effect of EMF vs. shamExpand

A model of human sleep homeostasis based on EEG slow-wave activity: Quantitative comparison of data and simulations
EEG slow-wave activity (SWA; spectral power in the 0.75-4.5 Hz band) is a function of the duration of prior waking and, thereby, an indicator of sleep homeostasis. We present a model that accountsExpand

Mathematical models of sleep regulation.
The level of EEG slow-wave activity (SWA) is determined by the duration of prior sleep and waking. SWA is a marker of nonREM sleep intensity and may serve as an indicator of sleep homeostasis. TheExpand

Dual electroencephalogram markers of human sleep homeostasis: correlation between theta activity in waking and slow-wave activity in sleep
To investigate the relationship between markers of sleep homeostasis during waking and sleep, the electroencephalogram of eight young males was recorded intermittently during a 40-h waking episode,Expand

Functional topography of the human nonREM sleep electroencephalogram
The sleep EEG of healthy young men was recorded during baseline and recovery sleep after 40 h of waking. To analyse the EEG topography, power spectra were computed from 27 derivations. Mean powerExpand

Effect of age on the sleep EEG: slow-wave activity and spindle frequency activity in young and middle-aged men
The effect of age on sleep and the sleep EEG was investigated in middle-aged men (mean age: 62.0 years) and in young men (mean age: 22.4 years). Even though the older men reported a higher number ofExpand

Pulsed high-frequency electromagnetic field affects human sleep and sleep electroencephalogram
To investigate whether the electromagnetic field (EMF) emitted by digital radiotelephone handsets affects the brain, healthy, young subjects were exposed during an entire night-time sleep episode toExpand
