Figure 2.

Cerebellum region (cerebellar analysis) showing significant differences between groups (older adults vs. middle-aged adults) on the GM (in mm³), and represented on a two-dimensional template with lobules indicated by roman numerals from I to X with a prepended H and V for the hemispheric and vernal compartment, respectively. On this image, the largest lobule HVII is divided into Crus I, Crus II (both corresponding to HVIIa) and HVIIb. Statistical significance threshold for the cluster level was set at p < 0.05 FWE corrected for multiple comparisons. We reported only one significant cluster (T = 4.99) belonging to the Crus I of the right cerebellum, with extent threshold defined as 20 voxels (voxel size = 1 mm³).
