  • PFC, Prefrontal cortex; RMPFC, rostromedial prefrontal cortex. Know = Know ratings. 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 (21–23 voxels or 671–735 mm3). 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.
