== Structure and Location == 
The primary motor cortex, also known as M1, F1, or Area 4, is located in the rear portion of the frontal lobe of the brain, before the central sulcus that separates the frontal lobe from the parietal lobe and along a bump called the precentral gyrus. M1 is only part of the complete motor cortex, which is also made up of the premotor area (PMA) and the supplementary motor area (SMA) of Area 6.
Interesting fact:
The motor cortex is responsible for movement, foot tapping, dancing and playing an instrument while the auditory cortex is responsible for the first stages of listening to sounds, and the perception and analysis of tones.
