Scalp topographies for faces in context based on a window (140-160 ms) around the peak for the N170. Upper panel left: scalp topography of fearful faces in fearful, happy and neutral scenes show the typical central positivity of the VPP and the occipito-temporal negativities of the N170. Upper panel right: happy faces in fearful, happy and neutral scenes. Lower panel left: scalp topographies based on difference waves show the prominent left occipito-temporal N170 and central VPP response to faces in fearful scenes, but neither for fearful faces in happy or neutral scenes, nor for happy faces in any of the scenes (lower panel right). Black dots in electrode-map depict sites on which difference is significant (t-test, P < 0.05, uncorrected).
