The term area 14 (macaque) refers to a portion of the straight gyrus of the frontal lobe defined on the basis of internal structure in the macaque. It is one of six subdivisions of the orbitomedial prefrontal cortex. area 14 is subdivided into two areas: area 14r (macaque) and area 14c (macaque) ( Carmichael-1994 ). Its human equivalent is area 14 ( Ongur-2003 ). The more rostral part, area 14r (macaque) is granular and thus has no equivalent in the rat ( Wallis-2012 ). The more caudal part, area 14c (macaque) is agranular and may have an equivalent; see orbital areas (rodent).
