How visual information transforms from pixels into people is more complex than dots becoming lines, lines becoming shapes, and shapes becoming faces. Your brain makes assumptions about all kinds of sensory information--even without you knowing it. Dr. Geoffrey Aguirre, a neuroscientist who specializes in vision processing, explains how we know what we can't really explain.
