Question

The premotor cortex is responsible for planning and executing movements, specifically those related to learned and repetitive movements such as playing a familiar song on the piano. Damage or dysfunction in this area can result in difficulty recalling the motor movements necessary to execute the task. The cerebellum is also involved in motor control but primarily plays a role in coordinating movement rather than planning and execution. The post-central gyrus and pre-central gyrus are primarily involved in sensory and motor processing respectively, but not specifically related to learned motor movements such as playing a specific song on the piano. The left temporal lobe is primarily associated with language processing, not motor function.
