PRP, parkinsonism-related pattern.
a
PRP topographies derived on a hemispheric basis.
b
Pearson's correlation coefficient computed on a hemispheric basis for voxels with loadings ⩾0.8.
c
PRP5L, PRP5R, and PRP5A represented the left and right hemispheres and the left/right average of voxel weights on PRP5, which was derived on a whole-brain basis (see text).
