The P300 waveforms for the wet-EEG approach. This figure depicts the waveforms that the N1, P3a (top) and the P3b (bottom) components for the Cz channel across the two conditions we examine in the auditory oddball task. Mean amplitudes of the deviant (oddball) condition are in red. The latency, displayed in black, is 229ms for the P3a and 371ms for the P3b components.
