Clusters with significant interactions or main effects in whole-brain analysis of risky vs. safe selection brain activation. Presented for each cluster is the anatomical location of significant voxels, the peak voxel coordinates in Talairach space, the size of the cluster, the corresponding F-value and effect size.
