The primary motor cortex (Brodmann area 4) is a brain region that in humans is located in the posterior portion of the frontal lobe. It works in association with other motor areas including premotor cortex the supplementary motor area posterior parietal cortex and several subcortical brain regions to plan and execute movements. Primary motor cortex is defined anatomically as the region of cortex that contains large neurons known as Betz cells.
