tDCS and Emotional Eating

The intervention will be applied using two sponge electrodes soaked in a saline solution. The stimulation montage will comprise left DLPFC anodal or sham stimulation. The reference (cathodal) electrode will be placed over the right supraorbital ridge, and the anodal electrode will be placed over the region corresponding to the left DLPFC (F3 of the EEG10-20 international system). The 2mA continuous current will be applied during the active stimulation condition via gradual ramps that start and stop after 30 seconds of stimulation (current ramps). For sham stimulation, the electrodes will remain in place for the whole session, but the current will only be applied for the first 36 seconds of the stimulation. Each tDCS session will last for 20 minutes.
