Acc. to Talairach and Tournoux (1988).

Normal volunteers in rest and activation state, norm‐rest and norm‐act; patients in rest and activation state, patients‐rest and patients‐act; patients with normal FDOPA uptake in caudate nucleus, subgroup A; groups with higher expression of PC were indicated first.
