Question

Quizplus · Accepted Answer

The SMA is primarily involved in the control of voluntary movements that are internally generated, such as planning and executing complex motor tasks. It is less active during the control of movements that are externally generated, such as reflex responses or simple movements dictated by external cues. Additionally, its activity is not specifically related to the completion of learned movements, but rather to the planning and execution of complex motor programs.
