Regions marked ** were significant at FWE voxel-level corrected p < 0.05 with extent size > 10 voxels.

Regions marked *were significant at FEW extent corrected p < 0.05 at primary voxel thresholds of uncorrected p < 0.001.

Regions marked ^† were significant at FEW extent corrected p < 0.05 at primary voxel thresholds of uncorrected p < 0.01.

Regions marked with* and with ^† were reported if these were additional regions.

BA denotes Brodman Area; Maxstat. denotes the maximum of the Z field.
