N250r: a face-selective brain response to stimulus repetitions

We investigated event-related brain potentials elicited by repetitions of cars, ape faces, and upright and inverted human faces. A face-selective N250r response to repetitions emerged over right temporal regions, consistent with a source in the fusiform gyrus. N250r was largest for human faces, clear for ape faces, non-significant for inverted faces, and completely absent for cars. Our results suggest that face-selective neural activity starting at ∼200 ms and peaking at ∼250–300 ms is sensitive to repetition and relates to individual recognition.
