Grand mean ERPs for the somatosensory (Soma) and auditory (Audio) conditions at the frontocentral site, Fz, for deviant (50 ms; red line), standard (100 ms; green line), and the subtraction waveform (mismatch, black line). The times indicate the midpoint latencies of the 40 ms windows over which the average amplitude of the MMNs were measured.
