Brain Signals of Face Processing as Revealed by Event-Related Potentials

Figure 2

Long-latency ERPs related to face recognition. Top: examples of facial N400-like ERPs (waveforms resulting from subtracting matching trials from mismatching trials) elicited in different tasks in which the degree of verbal and structural visual information involved was varied: a N360 (black) elicited by face-feature mismatching in faces learned without associated verbal information; a N380 (red) elicited by face-feature mismatching in faces learned with occupations and names; a cross-domain N440 (green) elicited by face-occupation mismatching; and a N370 (blue) elicited by occupation-name mismatching. Bottom: topographic voltage maps showing the scalp distribution of these ERPs in each task when the amplitude value was maximal.
