Sham Comparator
multi-channel tDCS
single-channel tDCS
sham stimulation
In the multi-channel tDCS stimulation group, a 1:4 (anode: cathode) approach was applied, with the central anode placed in the left dorsolateral prefrontal cortex (dlPFC) (reference 10-20 standard lead EEG), and the remaining cathode distributed around the central electrode. The rising time and falling time of current are 30 seconds respectively. Stimulate 30 minutes daily for 10 days (Monday to Friday, once a day, weekend off).
The anode electrode of the single-channel tDCS stimulation group was placed in the left dlPFC, and the cathode electrode was placed in the right orbital forehead. The rising time and falling time of current are 30 seconds respectively. Stimulate 30 minutes daily for 10 days (Monday to Friday, once a day, weekend off).
The shame stimulation group had only 30 seconds of up and down stimulation, with no intermediate stimulation.
