Plot of the mean percent change in binding potential (ΔBP) in regions where significant gender differences were found. Women showed greater ΔBP values than men in the right and left dorsal putamen and showed a nonsigificant trend toward higher ΔBP values in the left ventral striatum. Considered separately, the mean ΔBP in the left ventral striatum as well as in the right and left dorsal putamen was significant in women only. Right-left differences in ΔBP were significant in the ventral striatum only in men (p<0.001).
