A new quantitative EEG metric is described here that examines the temporal correspondence of magnitude modulation between cortical recording sites. It is termed ''comodulation,'' and is applied as a cross-correlation analysis either within-subject or statistically between subject and a control database. Analysis can be performed for any selected frequency band between 1 and 23 Hz and for each of four basic functional states, including eyes closed, eyes open, and two task engagement conditions. The metric is tested here by ap-
