ERP elicited by scrambled faces compared with the upright, intact faces in the two groups. (A) The N170 components. Notice the slightly larger N170 amplitudes in response to intact relative to scrambled faces in the elderly group and the inverse tendency in the younger group. (B) The Current Source Density (CSD) seen from the back and scalp voltage distribution of the N170 in response to scrambled faces seen from above. Notice that, as for intact faces, the distribution of the N170 to scrambled faces in the elderly group is symmetrical across hemispheres. (C) The effect of destroying the global shape of the faces (scrambled – intact, see text). Notice the opposite trends in the young and elderly groups.
