Notes: Reported clusters have a minimum cluster size of 4 voxels and were corrected for multiple comparisons voxel-wise using a threshold of p < 0.05. L – left hemisphere; R – right hemisphere; t-contrasts compared are shown in bold; Anatomical regions within each cluster are at least 4 mm apart and are ranked according to decreasing t-values.
