It shows the homunculus stretched out over the brain’s surface, a small body with enlarged mouth, hands and feet, each part exaggerated in proportion to the amount of neural real estate occupied.

That map of the primary motor cortex — the motor homunculus — shows how this brain region is divided into sections assigned to each body part that can be controlled voluntarily (SN: 6/16/15).

Since the 1930s, the so-called homunculus map has shown how different parts of the brain's motor cortex may control movement to different parts of the body. But it may be missing an important ...
