Three brain regions showing significant male:female x comparison:patient group interactions (<i>cf</i>., Tables 4 and 5).

<p>Dashed lines, males. Solid lines, females. Cmp, comparison participants. Pt, patients. Activation intensity is the mean activation difference (Decision Trial – Directed Trial) for all voxels in the cluster, so negative values indicate relative deactivation in Decision Trials, compared to Directed Trials. Standard errors of the means for each of these points lie in the narrow range ± 0.064–0.094.
