Sham Comparator
Active tDCS
Sham tDCS
The anode sponge electrode will be placed on the scalp over the left primary motor cortex (M1) and the cathode sponge electrode will be positioned over the right supraorbital cortex (SO). Active stimulation consists of 2 mA current applied continuously for 20 minutes.
The anode sponge electrode will be placed on the scalp over the left primary motor cortex (M1) and the cathode sponge electrode will be positioned over the right supraorbital cortex (SO). The 2 mA current will be applied for 30 seconds at the beginning of the session.
