Final answer:
The premotor cortex (PM) is located adjacent to the primary motor cortex in the frontal lobe. It aids in planning and coordinating movements, particularly the movements of the core muscles to maintain posture.
Step-by-step explanation:
The premotor cortex (PM) is located adjacent to the primary motor cortex in the frontal lobe of the brain. It is more lateral compared to the primary motor cortex. The premotor cortex aids in planning and coordinating movements, particularly the movements of the core muscles to maintain posture during movement.
