Grey-matter reductions from baseline to follow-up in Parkinson's disease without visual hallucinations with Mini-Mental State Examination score at baseline as a covariate
| Region | Cluster size (voxels) | Talairach coordinates (x, y, z) | t |
| Right primary motor cortex (BA4) | 340 | 22, −24, 55 | 5.59 |
| Right premotor and supplementary motor cortex (BA6) | 40, −7, 61 | 5.48 | |
| Left posterior cerebellum (inferior semilunar lobule) | 1118 | −8, −68, −37 | 5.25 |
| Left posterior cerebellum (vermis) | −4, −73, −30 | 4.79 |
Voxel and cluster level p<0.05 corrected by false discovery rate.
Coordinates correspond to the maximum significance.
