RESULTS
For all participants, alpha power was highest at occipital and parietal
electrodes, both for the eyes-closed and pre-stimulus EEG data. Alpha
power for pre-stimulus EEG-recording was substantially reduced compared
to eyes-closed EEG recording (Fig 2).

power, recorded from 128-electrode EEG. The topographies display data
averaged over all participants. Alpha band power was highest in the
occipital region for both eyes-closed EEG recording (left) and
pre-stimulus EEG recording (right).
