The term area 12 of Brodmann (human) refers to a subdivision of the cytoarchitecturally defined frontal region of the human cerebral cortex. Originally, it was described as part of the area 11 of Brodmann (human) but not shown in the cortical map of Brodmann-1909. In a subsequent publication ( Brodmann-1910 ), however, it was labeled as an independent area 12. It occupied the area between the superior rostral sulcus and the inferior rostral sulcus. Cytoarchitecturally it was bounded dorsally by area 10 of Brodmann (human) and area 32 of Brodmann (human); caudally, ventrally and rostrally it was bounded by the area 11 of Brodmann (human). Current maps of the human cerebral cortex have incorporated the topological area between the rostral sulci into area 10 ( Ongur-2003 ).
