The term area MII of Woolsey refers to a functionally defined area of mammalian cerebral cortex. It has been mapped in a number of species on the basis of movements elicited by electrical stimulation of the cortical surface. In the macaque It is the equivalent of supplementary motor area proper, a subdivision of the mesial premotor cortex ( Wise-1985a ). The face area is located anteriorly with the hind limb and tail areas extending posteriorly ( Woolsey-1958 ). In the rat ( Swanson-2004 ) and mouse ( Hof-2000 ) it is the functional equivalent of the premotor cortex, which is not ordinarily subdivided in rodents.
