Diagrammatic representation of the unfolded lateral (A) and medial (B) surfaces of the cerebral hemisphere in case 2 with isotope injection in the ventral part of the frontopolar area 10 (shown in solid black) and the resulting distribution of terminal label (shown as dots). In A, the principal sulcus, the lateral fissure, and the superior temporal sulcus have been opened up to show the terminal label in their banks. In B, the cingulate sulcus has been opened up.
