Interventions

Active High-definition transcranial direct current stimulationdevice

Participants completed 10 sessions of anodal HD-tDCS stimulation over 5 consecutive days (two 20-minute sessions per day, with a 3-hour interval between sessions). Stimulation was delivered using an HD-tES device (Soterix Medical, Inc, Woodbridge, NJ, USA), targeting the left dorsolateral prefrontal context (DLPFC). In the active HD-tDCS condition, current was ramped up to 2mA over 30 seconds, maintained for 20 minutes, then ramped down to 0mA at the end.

Sham high-definition transcranial direct current stimulationdevice

Participants completed 10 sessions of sham HD-tDCS stimulation over 5 consecutive days (two 20-minute sessions per day, with a 3-hour interval between sessions). Stimulation was delivered using an HD-tES device (Soterix Medical, Inc, Woodbridge, NJ, USA), targeting the left dorsolateral prefrontal context (DLPFC). In the sham condition, the current was ramped up to 2mA within the first and last 30 seconds to mimic the sensation of stimulation, but then ramped down, with no current maintained at other times.
