Event-related brain potentials (ERPs) elicited by changes of facial expression and changes in facial identity (actor). a Grand-averaged waveforms of the N240 component at the right temporoparietal site (P8, referenced to Cz). b N240 amplitudes for facial expression and identity changes (note that the average amplitude of individual subjects’ peak values is not equal to the peak amplitude of the grand-averaged waveform due to inter-subject variation in peak latency). c Grand-averaged waveforms of the P300 component at the midparietal recording site (average mastoid reference). d Average peak amplitudes of the P300 component elicited by change in facial expresison and identity at parietal midline location (Pz)
