Where is the motor cortex located in the brain?
Quick Answer
The motor cortex is in the frontal lobe, mainly along the precentral gyrus just in front of the central sulcus. It controls voluntary movement.
The Full Story
The primary motor cortex lies in the frontal lobe on the precentral gyrus, immediately anterior to the central sulcus. It sends signals down pathways that help initiate and control voluntary movements of the body. Different parts of the motor cortex correspond to different body regions in a map known as the motor homunculus. This topographic organization helps explain why fine movement control is concentrated in certain cortical areas.
