Clustersize values are based on the sum of all t-values in the observed clusters. P-values are determined by the number of random permutation clusters that showed a larger clustersizes than the observed clusters. Location abbreviations used: LF, left-frontal; FM, frontal-midline. Significant p-values are marked:

^*p < 0.05;

^**p < 0.01;

^***p < 0.001.
