Faces in the visual oddball paradigm: A possible mismatch negativity

Humans can process facial characteristics both rapidly and accurately, especially emotional expressions. Evoked-related potentials were used to examine brain activity during presentation of happy and neutral faces in an oddball paradigm. Mismatch negativity (MMN)- like activity was evident in most of the channels starting in lateral posterior channels and then spreading medially and anteriorly with a maximum value arround 280 ms.
