Height threshold: t-value = , uncorrected.

Extent threshold: voxels.

MNI coordinates of seed at left pre-SMA: [−8 8 52].

MNI coordinates of seed at right pre-SMA: [6 12 54].

Areas showing functional connectivity with pre-SMA as the entropy increases. This is the result of a conjunction analysis of the PPIs with seeded in left and right pre-SMAs. The psychological variable was the Shannon entropy of the decisions associated to each task configuration.
