motor homunculus

The motor homunculus is a visual representation of the areas of the brain responsible for controlling different body parts. It illustrates how much brain power is dedicated to each part; for instance, more brain space is allocated to areas like the hands and face, which need fine motor skills and precise movements. This mapping helps researchers understand how the brain coordinates movement and responds to injury. Essentially, it shows that while all body parts are controlled by the brain, some parts require more detailed control than others.
