The role of the primary motor cortex is to generate neural impulses that control the execution of movement.
Located in the rear portion of the frontal lobe
Your motor cortex must first receive various kinds of information from the various lobes of the brain: information about the body’s position in space, from the parietal lobe; about the goal to be attained and an appropriate strategy for attaining it, from the anterior portion of the frontal lobe; about memories of past strategies, from the temporal lobe.
Every part of the body is represented in the primary motor cortex
Primary Motor Cortex works with memory to judge and evaluate, then compute a physical action. It does this by problem solving and decision making, to acquire the physical production.
It is a part of the long-term memory that is procedural (implicit). These memories are typically acquired through repetition and practice, and are composed of automatic “sensorimotor behaviors” that are so deeply embedded that we are no longer aware of them, and just become automatic. This is implicit memory, because previous experiences (memories) aid in the performance of a task without explicit and conscious awareness of these previous experiences.
Examples: drinking water, riding a bike, tying a shoe, or even a dance routine.
The supplementary motor cortex programs M-1 (Primary Motor Cortex) for the execution of complex movements involving several muscles, particularly movements involving bilateral coordination
