The frontal lobe includes the primary motor cortex, the premotor cortex Broca's area, and prefrontal cortex.
What is frontal lobe ?
The area of the brain that is closest to the front is called the frontal lobe. It reaches back to the precentral gyrus from the region behind the brow. Higher cognitive processes like memory, emotions, impulse control, problem solving, social interaction, and motor function are all controlled by the frontal lobe as a whole.
Three distinct regions of the frontal lobe, directly anterior to the central sulcus, make up the motor cortex. These regions are the premotor cortex, the supplementary motor area, and the primary motor cortex (also known as Brodmann's area). These regions respond to electrical stimulation by moving certain body components. On the medial surface of the brain, the precentral gyrus and anterior paracentral lobule are home to the primary motor cortex, or M1. The main motor cortex, out of the three motor cortex regions, takes the least electrical current to stimulate a movement. Simple movements of particular body parts are often induced by low doses of short stimulation. Higher current levels are necessary to elicit movements when the premotor cortex or the supplementary motor region are stimulated, and frequently resulting in motions that are more complex than when the primary motor cortex is stimulated.
