The patient (CD) filmed in the videos showed below does not recognize famous faces when her right anterior fusiform gyrus is electrically stimulated by means of intracerebral electrodes. This region lies anteriorly to the right FFA, and shows face-selectivity in intracerebral recordings. The patient recognizes faces outside of the stimulation, and does not realize when she is stimulated. On video 2, she denies having been presented the face picture during stimulation.
