orbital prefrontal cortex
Acronym: OPFC
The term orbital prefrontal cortex refers to a segmentation of the orbital gyri on the basis of multiple stains for internal structure. One of two subdivisions of the orbitomedial prefrontal cortex, it is composed of six areas. In the human they are: area 10, area 11, area 47, area 13, area 14, and the agranular orbitofrontal cortex ( Ongur-2003 ). In the macaque area 47 was long named 'area 12' ( Carmichael-1994 ). The other division of the orbitomedial prefrontal cortex is the medial prefrontal cortex of Ongur.
     In both the human and the macaque the orbital prefrontal cortex is largely granular cortex, which has no equivalent in the rat. Only the most caudal strip of the orbital prefrontal cortex is agranular. The equivalent of that narrow area may be found in the orbital areas (rodent) and the agranular insular cortex of the rodent ( Preuss-1995; Wallis-2012 ).
