Figure 1.
Seed regions of interest (ROIs) (red) for functional connectivity.
A: Ipsilesional M1, MNI coordinate = −38, −22, 56, radius = 6 mm; B: Contralesional M1, MNI coordinate = 38, −22, 56, radius = 6 mm.
Figure 2.
Significant differences in the functional connectivity of ipsilesional M1 between each pair of the three diagnostic groups.
A: CPH versus PPH; B: PPH versus HC; C: CPH versus HC. The threshold was set at a combined cutoff value of p<0.01 and a minimum cluster size of 486 mm3 (18 voxels) to yield a corrected threshold of p<0.05 (AlphaSim corrected). Clusters with significant differences were overlapped on render views (posterior-anterior (row 1), right-left (row 2), inferior-superior (row 3)). Color scale = t values.

Significant differences in functional connectivity of contralesional M1 between each pair of the three diagnostic groups.
A: CPH versus PPH; B: PPH versus HC; C: CPH versus HC. The threshold was set at a combined cutoff value of p<0.01 and a minimum cluster size of 486 mm3 (18 voxels) to yield a corrected threshold of p<0.05 (AlphaSim corrected).
