“…The P1-N1-P2 complex was identified in the record referent to the frequent stimulus and the P300 was identified in the record referent to the infrequent stimulus, as the positive wave of greatest amplitude following the P1-N1-P2 complex. Absolute latencies (ms) and amplitude (µV) of the P1, N1, P2, and P3 components were analyzed, according to previous studies: P1: 51,63±10,93ms, 0,62±0,34µV; N1: 81,38±20,11ms, -0,95±0,27µV; P2: 143,11±18,37ms, 0,81±0,41µV; P3: 341±23ms, 2,12±1,07µV 22,23 .…”
