Selected ERP Waveforms for the Auditory Oddball (MMN/MMR) and Visual Evoked Potential (VEP) tasks. A) Auditory Oddball task ERP plots by condition for the Deviant, Standard, and their difference wave (Deviant – Standard) and B) their topography during the 200–400 ms time window. Note that only standard stimuli immediately preceding a deviant syllable were used. C) ERP plots for the VEP with the N1, P1, and N2 components labeled, and D) their topography during their respective time windows.
