  		Fig 1. Statistical maps analyzed by using 3D-SSP. The color of the outer contour corresponds to a Z score of 7. The relative decrease in rCBF (Z score of ≤2) in subjects 70–79 years of age compared with that in subjects 50–59 years of age (A, women; B, men). A marked reduction of rCBF was observed in the bilateral anterior cingulate gyri in each sex.
