This document discusses sensory homunculus, which is a representation of the human body that scales the size of different body parts based on the density of sensory nerve connections in that area. It specifically mentions that the hands, face, and tongue have denser connections and are therefore larger on the sensory homunculus scale compared to other body parts like the back and legs. The document also provides some website URLs related to sensory homunculus and sensory representations in the brain.
