orbitomedial prefrontal cortex (macaque)
Acronym: OMPFC
The term orbitomedial prefrontal cortex (macaque) refers to a segmentation of most of the orbital gyri, the straight gyrus, and the anterior cingulate gyrus of the macaque on the basis of internal structure and connectivity ( Carmichael-1994 ). The internal structure was analyzed in three species of macaque using nine histological stains. It is segmented into six subdivisions, which are further divided into 24 primary areas. Each area was shown to differ from adjacent areas by at least three stains. Though all boundaries do not coincide, the areas are named for the most part as subdivisions of prefrontal cortex (Walker) and cingulate areas (macaque).
     In the human orbitomedial prefrontal cortex the same subdivisions are found except that area 10 is divided into three parts, the equivalent to area 12 is named area 47, and an area 32pl is found, which has no equivalent in the macaque. For equivalent areas in the rat and mouse see orbital areas (rodent).
