x, y, and z refer to coordinates of the peak age differences in MNI space. Psc values show the mean (and SD) parameter estimates for each age group separately (converted to percentage signal change and based on a 6 mm3 ROI) in order to illustrate the origin of the age effect (Z).
↵*Significant at p < 0.001 (did not survive GRF cluster-size correction for multiple comparisons). +ROIs for which we found significant associations with D1 receptor density (Fig. 2).
