Experimental
Sham Comparator
tDCS active
tDCS sham
Stimulation will be performed with the anode placed over the right DLPFC, and the cathode placed on the left DLPFC. The applied electric current will be 2mA and is going to be applied for 20 minutes. The electrodes have a size of 35cm ² each and will be covered by sponges soaked with saline. The stimulator to be used will be the "Chattanooga Ionto ISO 13485". Stimulation will be performed for 5 days, one time per day.
For the sham tDCS, the same setting will be used. However, the current is going to be applied for only 30 seconds, not being able to induce effects on neuronal excitability.
