The term area 14 (14) refers to an area occupying the part of the straight gyrus (SRG) that forms the lower margin of the medial surface of the frontal lobe (FLB) in the human ( Mai-1997 ) and the macaque ( Martin-2000 ).. Histologically it is identified by multiple stains. In the human, it is bounded dorsally on the mesial surface of the lobe by area 10m and caudally by area 32pl. On the ventral surface it is bounded laterally and caudally by area 13. On both surfaces it is bounded rostrally by area 11m. It is one of nine subdivisions of the orbitomedial prefrontal cortex in the human; the others besides those mentioned are area 24, area 25, and area 32ac. area 14 is divided into two areas: area 14r and area 14c. For the relations of this segmentation and terminology to others, see Ongur-2003. The equivalent area in the macaque is area 14 (macaque). The rat may have an equivalent to the caudal portion, area 14c, which is agranular cortex ( Wallis-2012 ). See orbital areas (rodent).
