Wilder Penfield and his co-investigators Edwin Boldrey and Theodore Rasmussen are considered to be the originators of the sensory and motor homunculi. At the very top end of the primary sensory cortex, beyond the area for the toes, it has traditionally been believed that the sensory neural networks for the genitals occur. This means that the primary cortex in the right cerebral hemisphere represents motor activity on the left side of the body and viceversa.

Penfield first conceived of his homunculi as a thought experiment, and went so far as to envision an imaginary world in which the homunculi lived, which he referred to as “if”.
More recent studies have improved this understanding of somatotopic arrangement using techniques such as functional magnetic resonance imaging fMRI.
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.
