Figure 4. Scalp distribution of ERP differences in Event-based and Time-based PM conditions.

Figure 4

The amplitudes shown are obtained as differences PM block-minus-baseline block of the ERPs time-locked to ongoing trials. Average Maps are shown for the time windows in which the ERPs were analysed.
