The term area 47/12l refers to one of four subdivisions of area 47 in the orbital gyri of the human cerebral cortex. Composed of granular cortex, it is defined on the basis of multiple stains for internal structure. It is located at the lateral margin of the lateral orbital gyrus. It is bounded medially by area 47/12m, rostrally by area 47/12r, and caudally by the agranular orbitofrontal cortex. The fourth subdivision is area 47/12s. For the relations of this segmentation and terminology to others, see Ongur-2003. The equivalent area in the macaque is area 12l (macaque). As granular prefrontal cortex, it has no equivalent in the rat ( Wallis-2012 ).
