Cortical homunculus A cortical homunculus is a distorted representation of the human body, based on a neurological "map" of the areas and proportions of the brain dedicated to processing motor functions, or sensory functions, for different parts of the body. Homunculus is Latin for "little man", and was a term used in alchemy and folklore prior to the concept being utilized in scientific literature. A cortical homunculus, or "cortex man", illustrates the concept of a representation of the body lying within the brain.
