Electrical activity of the brain at a frequency of around 1–8 Hz, typical of sleep. The resulting oscillations, detected using an electroencephalograph, are called delta waves.
δ节律
Example sentencesExamples
Research has shown alpha wave intrusion into non-REM delta wave sleep 70% greater than controls.
As the participant enters deeper sleep, large amplitude delta waves may be observed.
Brain research has shown that using sound phasing for brain synchrony will adjust the brain waves to deeper states down to the delta wave pattern.
By stage 4, the brain produces delta waves almost exclusively.
The amplitude of delta waves is very high relative to other frequencies.
