DEC 12, braincheck: homunculi

Authors' Note:  The homunculi (Latin, for little persons) referred to here are the representations of the human body, well-known to anatomy students, that are mapped out on the "motor strip", symmetric areas of cortex on both sides of the brain that control voluntary movement on the contralateral side of the body. The motor homunculus on each side maps the primary motor cortex, located in the precentral gyrus (fold) of the frontal lobe; analogously, there is a similarly arranged sensory homunculus located nearby in the postcentral gyrus.
