Interventions
Group A:Stimulation in the M1 area: central electrodes are placed in the primary motor cortex (M1), i.e., Cz
the remaining four return electrodes are placed at C3, C4, Fz, and Pz. Current: 2mA
Group B:Left DLPFC stimulation: Place the central electrode in F3. The other four return electrodes are placed at FC1, AF3, F7, and FC5. Current: 2mA
Group C:sham stimulation, in which a central electrode is placed in the primary motor cortex (M1), i.e. Cz
The remaining four return electrodes are placed at C3, C4, Fz, and Pz. Current: 0mA
