Humans have five distinct senses: sight, sound, touch, taste, and smell. For decades, researchers have thought that each sense is processed separately in the cortex, or outer layers of the brain, and then later integrated by separate brain areas. Cortical tissue near the back of the brain holds cells sensitive to vision, for example, while the area above the ear reacts to sounds. But recently, researchers have begun to question this so-called “uni-modal” model of sensory processing, suggesting instead that cortical regions respond to and integrate information from several senses at once.
