Height threshold: t-value = , uncorrected.

Extent threshold: voxels.

MNI coordinates of seed at right MCC: [12 18 42].

Areas showing functional connectivity with right MCC as the entropy increases (PPI analysis). The psychological variable was the Shannon entropy of the decisions associated to each task configuration.
