Twenty 2-mA sessions (ramp-up and ramp-down periods of 30 and 30 seconds, respectively) were applied for 20 minutes per session, twice daily over 10 consecutive days, and the stimulus frequency was set as 6Hz.
Sham tACS was delivered using the same protocol and current intensity, but the period of active stimulation was only during the ramp-up and ramp-down periods of 30 and 30 seconds.
