↵aValues depict the subject's choice in a visual analog scale in which 1 represents poorest attention, maximal fatigue, and pain and 7 represents maximal attention, least fatigue, and pain across stimulation intensity (1 mA, 2 mA cathodal tDCS).
↵bValues represent CBI with an ISI of 3 ms over time (pre, post 1, post 2, post 3) and stimulation intensity (1 mA, 2 mA).
