Two tiny brain areas are key for seeing and recognizing faces, according to a new study that sheds light on a rare neurological disorder known as facial blindness. Stanford University neuroscientists used electrical pulses to tickle the brain areas, called the mid and posterior fusiform gyri face-selective regions. “Your nose got saggy and went off to the left,” study subject Ron Blackwell said, describing a deliberately distorted face in a video accompanying the study. “You just turned into somebody else. Your face metamorphosed.”
