The motor cortex corresponds to Brodmann's area 4 (MM). The primary motor cortex, or M1, is located on the precentral gyrus and on the anterior paracentral lobule on the medial surface of the brain. Of the three motor cortex areas, stimulation of the primary motor cortex requires the least amount of electrical current to elicit a movement. http://neuroscience.uth.tmc.edu/s3/chapter03.html. gyrus precentralis excitable area UBERON:0001384 FMA:224854 motor cortex prefrontal gyrus BAMS:M1 SCTID:11931008 MA:0000907 primary motor area frontal cortex regional part of brain
