The Premotor Cortex is another key motor planning region in the brain. It works in conjunction with the SMA to plan and execute movements but is specialized as is the SMA. Specifically, the Premotor Cortex seems to play a key role in encoding the direction of intended movements. Further, the Premotor Cortex seems to play a greater role in externally generated movements. The PMC also seems to play a role in controlling movements of the trunk and the parts of the body closer to the midline.
