From left to right, the extent of the cluster in number of voxels (K; 2 × 2 × 2 mm³), the hemispheric lateralization (H; L, Left; R, Right), the estimated anatomical region [and Brodmann Area where available in the Anatomy Toolbox (Eickhoff et al., 2005)], the stereotactic coordinates (MNI), the local-maxima T-score and the cluster p-value, are reported for the regions that were more strongly activated by exploitative than explorative decision-making (top), and explorative than exploitative decision-making (bottom). Values shown in the Cluster p-value column survive a statistical threshold of p < 0.05 corrected for multiple comparisons. CA, Cornu Ammonis; IFG (p. Orbitalis), pars orbitalis of the Inferior Frontal Gyrus; IFG (p. Triangularis), pars triangularis of the Inferior Frontal Gyrus; SMA, Supplementary Motor Area; SUB, Subiculum; vmPFC, ventromedial prefrontal cortex.
