Treatment - Other

Left anodal stimulation: In this intervention anode will be placed on the left DLPFC that enhance the cortical activities and cathode will be placed on the right orbitofrontal.

Left cathodal stimulation: In this intervention cathode will be placed on the left DLPFC that enhance the cortical activities and anode will be placed on the right orbitofrontal.

Sham stimulation: in this situation electrodes will be placed on the participant's head for 15 minutes without any stimulation. This session will be considered as a method of control.
