EEG signals are measured based on their frequency (Hertz, Hz) and amplitude (voltage).

: Distinct bursts of 11–16 Hz activity (most commonly 12–14 Hz) lasting at least 0.5 seconds.

EEG and Sleep Physiology: A Comprehensive Overview Electroencephalography (EEG) is the primary tool used to study the neurophysiological changes that occur during sleep. By recording electrical activity from the scalp, EEG allows researchers and clinicians to categorize sleep into distinct stages and identify physiological markers of health and disorder. 1.
