Figure 2.

Results of voxel-based regression analyses showing (A) significant clusters in the bilateral cerebellar hemispheres where ¹¹C-flumazenil binding potential (BP) in cervical dystonia (CD) patients correlated with dystonia severity as measured by the Toronto Western Spasmodic Torticollis Rating Scale (TWSTRS), and (B) significant clusters where ¹¹C-flumazenil BP in CD patients correlated with disease duration. Significance was defined as an individual voxel statistical threshold of p < 0.005 with a cluster threshold of 100 contiguous voxels. Images are displayed such that left is anatomical left. Abbreviations: Cu, cuneus; OC, olfactory cortex; TP, temporal pole.
