The hands have the greatest amount of representation in the human primary somatosensory cortex. This is known as the sensory homunculus, where each part of the body is represented on a specific area of the somatosensory cortex depending on the amount of sensitivity and movement associated with it. The hands have the highest representation because of their fine motor skills and high sensitivity to touch.
