Fig. 6.
Examples of electrode penetrations in two monkeys (right hemisphere from Monkey #1 and left hemisphere from Monkey #2). Similar distributions were observed in the other hemispheres (data not shown). Circles indicate go type C cells; plus signs indicate no-go type C cells.Small symbols indicate one cell; large symbols indicate two cells. A circlesuperimposed on a plus sign indicates a location in which both types of C cells were found. In penetrations indicated bysmall dots, no C cells were found. PS, Principal sulcus; AS, arcuate sulcus. Theinset is a lateral view of the left hemisphere and shows the location of VLPFC (gray area).
