The term area 10r refers to one of three subdivisions of area 10 in the human. Defined on the basis of multiple stains, it occupies rostral parts of the superior rostral gyrus and the inferior rostral gyrus on the medial surface of the frontal lobe. It is bounded caudally by area 10m and rostrally by area 10p, dorsally by area 32ac, and ventrally by area 11m. The other subdivisions of area 10 are area 10p and area 10m. It has an equivalent area composed of two subareas in the macaque: area MFc and area MFr ( Ongur-2003; Preuss-1991 ). As granular prefrontal cortex, it has no equivalent in the rat ( Wallis-2012 ).
