A cortical homunculus is a distorted representation of the human body, based on a neurological "map" of the areas and proportions of the human [[Brain]] dedicated to processing motor functions, or sensory functions, for different parts of the body. The word homunculus is Latin for "little man", and was a term used in alchemy and folklore long before scientific literature began using it. A cortical homunculus, or "cortex man", illustrates the concept of a representation of the body lying within the brain. Nerve fibres from the spinal cord terminate in various areas of the parietal lobe in the cerebral cortex, which forms a representational map of the body. <ref>[https://en.wikipedia.org/wiki/Cortical_homunculus Cortical Homunculus]</ref> | A cortical homunculus is a distorted representation of the human body, based on a neurological "map" of the areas and proportions of the human [[Brain]] dedicated to processing motor functions, or sensory functions, for different parts of the body.
