Grand averaged event-related brain potential waveform for the SRT task with a right hand button-press. N1 and P2 are evident, as well as a left-lateralized negativity over left motor areas between 300 and 400 ms (see C3 site vs. C4 site) that appears to show a corresponding positivity contralaterally more posteriorly (see T4 site).
