Figure 2. .

Brain activation for the indirect vs. direct contrast, for each group separately as well as for the interaction between the groups. The figure shows F values for clusters with a cluster-forming threshold of p_uncorrected = 0.001 (no extent-level threshold, k = 0). As a multiple comparison correction method, we used family wise error (FWE) correction at the cluster and peak level. We only report clusters and voxels with a p_FWE < 0.05. All clusters are projected onto a pial surface. The activation for the interaction is shown in orange to yellow. The activation for the high (low) score group is shown in blue (green). The regions where the activations in both groups overlap are shown in solid red and no activation information is given. Note that the range of the scales do not reflect the exact max (min) value of the unit of activation (which is customary) but are adjusted slightly so as to include values from all hemispheres.
