How Blind People Recognize Faces via Sound

A new study reveals that people who are blind can recognize faces using auditory patterns processed by the fusiform face area, a brain region crucial for face processing in sighted individuals. The study employed a sensory substitution device to translate images into sound, demonstrating that face recognition in the brain isn't solely dependent on visual experience.
