Textbook homunculus diagram depicts how the brain controls individual body parts — the revamp could improve treatments for brain injury.

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 ...

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).

Motor homunculus regions were thought to only be linked to each other across the brain’s hemispheres, the left hand with the right hand, and the left foot with the right foot.
