milliseconds poststimulus, the novel-sound P3 latency from the most positive peak at Cz at 200 to 550 milliseconds, the target N2 latency from the most negative peak at Cz at 150 to 350 milliseconds, and the target P3 latency from the most positive peak at CPz (an electrode between Cz- and Pz-lines) at 200 to 550 milliseconds. The latencies of standard-tone N1 (50 to 150 milliseconds poststimulus) and P2 (150 to 300 milliseconds poststimulus onset) components were determined at the FCz. Mean latencies and amplitudes of novel P3, target P3 and standard P2 are shown in Table 2.
