Study design and experimental setup. a Procedures for session 1 and 2. Study procedure for both sessions was identical, starting with an initial run of the test block MoSlo (motor slowing) containing hand tapping tasks (HTT) for left (HL) and right (HR) hand and foot tapping tasks (FTT) for left (FL) and right (FR) foot. Afterwards, transcranial direct current stimulation (tDCS) was applied over the leg area of the primary motor cortex (M1 leg area) for a period of 20 min, symbolized by the lightning. Participants were randomly assigned to one stimulation type, receiving either the anodal tDCS condition (red lightning) or the control condition (white lightning), where sham tDCS was applied (the other condition was applied in session 2, accordingly). Another run of HTT and FTT was performed after 10 min of stimulation (during tDCS, online) as well as directly after and 30 min after stimulation has ended (offline). b Behavioral tasks. Participants were asked to perform four runs of the test block MoSlo (initial, during, after and 30 min after tDCS), each consisting of two runs of a 20-second HTT and FTT for each hand and foot separately. Tapping frequency was analyzed in 5-second bins
