The term area SII 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 evoked potentials elicited in the cortex by light touch stimulation of the skin. In the macaque the trunk and limbs are represented in the superior bank of the lateral fissure with the face area extending onto the surface of the postcentral gyrus ( Woolsey-1958 ). It is the same as the secondary somesthetic area ( Carpenter-1983 ).
