Results are cluster corrected for familywise errors (p < 0.05) with a cluster size of >20 voxels. Significant clusters are shown for the contrast (real tDCS > baseline1) > (sham > baseline 2) and real tDCS > baseline1 for each of the four networks. Resting-state network contrast (RSNc) 1 corresponds to the contrast of the DMN, RSNc 2 corresponds to the contrast of the left FPN, and RSNc 3 corresponds to the contrast on the right FPN. Results are cluster corrected for familywise errors (p < 0.05) with a cluster size of >20 voxels. Numbers correspond to clusters shown in Figure 4.
