Human brains actually have a homunculus map (or more properly cortical homunculus). There’s basically a vertical stripe of the brain on each side that contains the main sensory (toward the front) and motor (towards the back) neurons for the opposite side of the body, inverted, so the feet are towards the top and the face at the bottom. The amount of space each part of the body takes up on the map depends on how many nerves that part has, not its actual size, making the hands and tongue proportionally the largest parts of the body (and the genitals, but only on the sensory side). Googling “homunculus map” will get you some very, very strange models demonstrating these proportions.

Brains are weird.
