Time by intervention interaction in PPI connectivity within and between large-scale network nodes: Exploratory ROI-to-ROI gPPI results. Task-based modulation in connectivity with time x intervention interaction (P uncorrected < 0.05) between the main node of three large-scale networks in the Yeo atlas, including ECN, DMN, and VAN. Within the network, task-based modulation in connectivity did not survive correction using the FDR method. A small dot is an indicator of the main node of a large-scale network. ECN, frontoparietal network; DMN, default mode network; VAN, ventral attention network; FrOperIns, frontal-operculum-insula; Med, medial; ParOper, parietal-operculum; PFC, Prefrontal cortex; TempOcc, tempro-occipital-parietal; TempPar, tempro-parietal; PcunCing, precuneus cingulate; PcunPCC, precuneus posterior cingulate cortex; R, right side; L, left side; blue line, a decreased PPI connectivity between to ROIs in active tDCS while it increased in sham, red line: an enhanced PPI connectivity between two ROIs in active tDCS, while it decreased in the sham.
