Note: Activations in table were thresholded voxelwise at P < 0.001 and with a cluster size set to control for multiple comparisons over whole brain at P < 0.05 (30–46 voxels). T-statistics were converted to Z-scores for reporting. Coordinates are reported in MNI space, as in SPM8. Voxel size was 3 × 3 × 3.2 mm.
