Significant quadratic differences between verum and sham tDCS group revealed by TBM. Overlay of statistical parametric maps (uncorrected p < 0.001) shows a significant quadratic difference in the left lingual gyrus (A). The color bar indicates the t-score. Comparison of the statistical parametric maps (uncorrected p < 0.005, for illustrative purposes) of the cross-sectional cluster (in yellow) and the longitudinal cluster (in red) reveals that the regions of both clusters in the left lingual gyrus overlap (B)
