Mean amplitudes of P1 and N1 at Cz in the isochronous and jittered conditions. Mean amplitudes (μV) are indicated with SE values in parentheses. Number of epochs: n between brackets. The time window used in the statistical analyses for Monkey A is 20–40 ms for the P1 and 40–60 ms for the N1. For Monkey A the time window used is 18–38 ms for the P1 and 40–60 ms for the N1.
