Table 1.

List of p values resulting from the source modeling analysis performed for each time window (0–50, 50–100, and 100–150 ms) within the four Brodmann's areas (BAs), that corresponded approximately to the four clusters.

	BA 7 L	BA 7 R	BA 6 L	BA 6 R
CATHODAL
0–50 (ms)	p = 0.736	p = 0.729	p = 0.513	p = 0.605
50–100 (ms)	p = 0.232	p = 0.204	p = 0.683	p = 0.787
100–150 (ms)	p = 0.484	p = 0.582	p = 0.835	p = 0.656

In particular, BA 7 L is the Left parietal cluster (TMS site; CP1, CP3, P1, and P3); BA 7 R is the Right parietal cluster (tDCS cathode; CP2, CP4, P2, and P4); BA 6 L is the Left frontal cluster (F1, F5, FC1, and FC3); BA 6 R is the Right frontal cluster (F2, F6, FC2, and FC6).
