The contrasts of interest for the decision phase yielded several regions defined by strength of effect (p<0.001, uncorrected for multiple comparisons) and size (10 or more voxel). The stereotaxic coordinates of the peak of the activation are given according to Talairach space, together with the F-value for the cluster peak.
