Hands and Feet in the Motor Cortex

The primary motor cortex contains a body map for movement control. This map sits in the precentral gyrus, just in front of the central sulcus. Nearby, the postcentral gyrus holds the primary sensory cortex, which receives touch, pain, and temperature information from the body.

This body map is of...

Motor information is organized according to anatomical divisions in the primary motor cortex, creating a topographical map in the brain.

Located in the precentral gyrus, cortical representations of the body are organized into a motor homunculus?"little man"?and are arranged in an inverted manner, such that the areas that control the toes a...
