(a) Stimuli in the choice reaction task. (b) The tDCS/fMRI paradigm: each run comprised four blocks each of CRT + anodal, CRT + cathodal, CRT + sham, “rest” + anodal, “rest” + cathodal, and “rest” + sham tDCS. Each block was followed by a brief period of black screen and no stimulation. Each participant had three runs (performing 36 task blocks and 36 rest blocks in total).
