Abstract: A method is presented for searching any number of simultaneous time series (e.g. from different EEG electrodes) for single generators within a frequency band. The method was applied to human EEGs taken during conditions of listening to complex rhythmic (Mozart symphony and chanting) and non-rhythmic (conversation) sounds. The method indicated a tendency towards single generation in the alpha (8-12 Hz) band during the rhythmic conditions. The method was then extended to test for synchrony between the EEG signals and the auditory signal (as a function of frequency). Such synchrony (auditory driving) was indicated during rhythmic conditions in the alpha band.
