N250r: a face-selective brain response to stimulus repetitions

Neuroreport. 2004 Jun 28;15(9):1501-5. doi: 10.1097/01.wnr.0000131675.00319.42.

Abstract

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.
