Anatomical structure | Hemisphere | Cluster size [voxel] | T-Value | x | y | z |
Substantia nigra* | R | 4 | 7.2 | 10 | -22 | -20 |
Insula | L | 10 | 6.64 | -36 | -2 | 4 |
Anterior cingulate cortex | L/R | 10 | 5.66 | -2 | 18 | 26 |
Data are thresholded at p<0.001 (uncorrected), with a cluster-level of k=10 and (*) k=4 in the midbrain (SVC-corrected p=0.018 for the SN cluster).
Neither of the cortical activations were significant on the cluster-level (p<0.05) after correction for multiple comparisons with respect to the whole acquired partial volume.
