Deviant waveshapes across the dry- and wet-EEG approaches. The data demonstrate the P300 for the deviant (oddball) condition as registered with the dry-EEG (thin line) and the wet-EEG approach (bold line) and the clear evidence for the N1, P3a and P3b components. We report a ~48ms latency difference across the two approaches, with the dry approach exhibiting the relatively shorted onset of the N1, P3a and P3b. The N1 peak occurs at ~120ms and ~170ms for the dry- and wet-EEG approaches, respectively. The dry-EEG N1 also has a relatively more negative amplitude peak value as compared to the wet-EEG approach.
