Schematic representation of the experimental design. tDCS was applied on five consecutive days, using a GOT to quantify behavioural effects. Each testing session began with baseline assessment of the right index finger (IF). Thereafter, tDCSanodal/sham was applied for 20 minutes. To measure effects on tactile performance, the GOT was conducted at intervals 10, 30, 60, and 90 minutes after the onset of the tDCSanodal/sham delivery. fMRI sessions were conducted one week prior to the first tDCS application, on the last day of tDCS application and about four weeks after the second fMRI session. On the first day of testing, MEG and a neuronavigational system were used for tDCS electrode placement. A front view of the device used for GOT testing is depicted in small image in Figure 1. GOT‐pens were presented by releasing a lever on side of the device (1) and were changed by another control shifter on its front (2, traced by white lines).
