The EEG was recorded in reference to the left ear lobe with Ag/AgCl electrodes (inner diameter 6 mm) from 60 scalp locations and the ear lobes, using an electrode cap (EasyCap GmbH, Germany). Two additional electrodes were placed near the right eye (3 cm above, inside the vertical pupil axis and 1.5 cm below, outside the vertical pupil axis) for the recording of vertical and horizontal eye movements. The impedance of the electrodes was always below 11 kΩ.
