area 47
Acronym:
47
The term area 47 refers to the lateral portion of the orbital gyri segmented on the basis of multiple stains for internal structure in the human ( Ongur-2003 ). Composed of granular cortex, it is located between the agranular orbitofrontal cortex posteriorly, area 11 anteriorly, and area 13 medially. It extends across the ventral margin onto the lateral surface of the frontal lobe, where it is bounded superiorly by area 45 caudally and area 10 rostrally. It is one of five subdivisions of the orbital prefrontal cortex; the others, in addition to the three mentioned, are area 14 and the orbital portion of area 10p. It is subdivided into four areas: area 47r, area 47m, area 47l, and area 47s. The equivalent area in the macaque is often referred to as area 12 ( Ongur-2003 ) or area 47/12 ( Petrides-2012 ). As granular prefrontal cortex, it has no equivalent in the rat ( Wallis-2012; Ongur-2003 ).
