Cluster size denotes the extent of the cluster of significant voxels. MNI coordinates refer to the location of the most statistically significant voxel in the cluster.

*Differences are significant at p < .001 uncorrected.

**Differences are significant at p < .05 corrected for family-wise error (FWE).

PD = Parkinson’s disease; ToM = Theory of Mind; R = Right; L = Left; FA = Fractional Anisotropy; MD = Mean Diffusivity; RD = Radial Diffusivity; MNI = Montreal Neurological Institute; df = Degrees of Freedom.
