  • All areas were significant to p < 0.0001, uncorrected, with cluster size <20 voxels. Activity directly attributable to task performance was excluded by masking with F-contrast voxels of the three task-related regressors atp < 0.0001. L, Left; R, right.

  • F1-a Coordinates are given for the stereotactic space of Talairach and Tournoux (1988).

  • F1-b Voxel-level significance at p< 0.05 corrected for whole brain.

  • F1-c Cluster-level significance at p< 0.05 corrected for whole brain.
