| BA 44 | Right inferior frontal gyrus | 53 | 10 | 12 | 247 | 4.41 | <0.0005 |

These activations represent negative correlations—that is, greater activity for younger participants. Activation maps are presented with a peak-level threshold of p < 0.001 uncorrected, with a cluster (extent) threshold of 30 voxels.
