Effect of Long-term Transcranial Direct Current Stimulation (tDCS) on Appetite Control Related Brain Regions

For active tDCS, a 2 mA current will be delivered for 20 minutes with 20 second up and down ramp times. The anodal electrode will be placed on the right DLPFC (F4; 10-20 EEG system), and the cathode electrode will be placed on the left DLPFC (F4;10-20 EEG system), which is known to be related to cognitive function. The electrodes used for tDCS are saline-soaked sponges (25 cm2).

Sham tDCS will be delivered for 20 minutes.
