The term area 10 of Brodmann (human) refers to a subdivision of the cytoarchitecturally defined frontal region of cerebral cortex. It occupies the most rostral portions of the superior frontal gyrus and the middle frontal gyrus. In human, on the medial aspect of the hemisphere it is bounded ventrally by the superior rostral sulcus. It does not extend as far as the cingulate sulcus. Cytoarchitecturally it is bounded dorsally by the area 9 of Brodmann-1909 (human), caudally by the area 46 of Brodmann (human), and ventrally by the area 47 of Brodmann (human) and by the area 12 of Brodmann (human) or, in an early version of Brodmann's cortical map ( Brodmann-1909 ), the area 11 of Brodmann (human).
