Figure 5. — Regions of decreased perfusion after stimulation compared with during stimulation [i.e., (tDCS_aftereffects − tDCS_baseline); n = 12; mixed effects, corrected cluster threshold, Z > 2.0, p < 0.01]. A, Regions of decreased perfusion after anodal tDCS. Decreased perfusion can be seen in the frontal lobes and the precuneus bilaterally. For ease of comparison, the results of the contrast (anodal_aftereffects − anodal_stimulation) are shown in green. B, Regions of decreased perfusion after cathodal tDCS. Decreased perfusion can be seen in the frontal and temporal lobes bilaterally. For ease of comparison, the results of the contrast (cathodal_aftereffects − cathodal_stimulation) are shown in purple. R, Right.
