area MI of Woolsey
Acronym: MI
The term area MI of Woolsey refers to an area of mammalian cerebral cortex. It is the functionally defined equivalent of primary motor cortex ( Carpenter-1983 ). It has been mapped in a number of species on the basis of movements elicited by electrical stimulation of the cortical surface in animals under anesthesia. In the macaque it is located on the exposed surface of the precentral gyrus with extensions into the anterior bank of the central sulcus and the posterior bank of the arcuate sulcus. The face area is located on the lower lateral surface with part of the hind limb and tail areas extending over the midline into the bank of the longitudinal fissure ( Woolsey-1958 ).
