This remarkable video clip was released to accompany the 2012 paper “Electrical stimulation of human fusiform face-selective regions distorts face perception.” Onscreen is the patient, who has undergone a surgical implantation of subdural electrodes in an effort to localize the focus of his seizures. Offscreen is the neurologist, Josef Parvizi, whose voice is heard asking about the effects of administering electrical stimulation (variously "4mAmp" or "3mAmp") to the targeted region of the FFA, or "SHAM" stimulation (a switch is clicked, but no current is passed), while the patient looks first at Parvizi's face, then the face of another person in the room, then non-face objects in the hospital room.
