Because of low numbers of studies (four studies), we did not conduct meta-analysis for externally guided decision-making under uncertainty using perceptual difficulty. Internally guided decision-making using preference judgment showed no significant region because of the low number of studies (seven studies).

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 maximum of the Z field.
