Homunculus
In the brain, every part of the body is represented in precisely defined locations, both sensorily and motorically. Body parts with a high density of sensory receptors (fingertips, tongue) are represented more prominently than those with a lower receptor density (back, legs). Neural maps are developed, e.g., of the hand or face. If these maps are graphically assigned to their body parts, the result is a homunculus, i.e., a small human being. The size of its respective body parts reflects their motor capabilities or sensitivity. This makes the homunculus appear strangely distorted.
