Group average difference waves and scalp topographies for the time windows of MMR, P3a and RON. Upper panel: Difference waves (novel minus standard sound) for both age groups at Fz. Time windows for the statistical analysis are highlighted. Lower Panels: Voltage and scalp current density (SCD) topographies for the time windows of MMR, P3a and RON in both memory load conditions for both age groups (children left, adults right).
