Abstract
The mean integrated amplitude of both EEG and upper facial EMG activities was monitored during varied vigilance states including wakefulness, sleep, anesthesia and coma. Combined monitoring provided more useful information than that available from EEG alone. Drug-free wakefulness was consistently associated with high-amplitude (>10 mcV) EMG and low-amplitude (<20 mcV) EEG activity. Diminished vigilance was reliably indicated by diminished EMG amplitude. In contrast, decreased vigilance was not necessarily manifested by increased EEG amplitude. Thus, combined EEG/EMG monitoring seems to enhance the information content of biopotentials derived from scalp recordings.<>
