Overlaid map of FP-CIT standardized uptake value ratios from the (a) better response and (b) poorer response groups. For visualization purposes, overlaid maps were spatially smoothed using a Gaussian kernel of 8-mm full-width at half maximum. The coordinate indicated by the crosshair is the anterior putamen, which are positions corresponding to 10, 10, -5 in the MNI-152 coordinate system. The color bar represents the uptake intensity from the minimum to the maximum (scaled from 0 to maximum values).
