Subjects will undergo to Transcranial Direct Current Stimulation with anode in left dorsolateral prefrontal cortex and cathode in right supra orbicular region. The stimulus will be 1mA for 20 minutes.

Subjects will undergo to procedure similar to the Transcranial Direct Current Stimulation with anode in dorsolateral prefrontal cortex and left cathode region supraorbicular right. They will receive a stimulus of 1mA only in initial 30 seconds and it will change the electrical charge for 0mA after this time, however the electrodes will be kept for 20 minutes as the active arm.

This technique consists in the use of low voltage electric current to increase or reduce neuronal excitability in the area stimulated. This is a non-invasive and safe intervention having infrequent and insignificant side effects characterized by mild local discomfort, itching, tingling and/or headache of short term.

Quantitative electroencephalography to assess the neurobiological aspects evidenced by the amount of brain electrical activity observed by the amplitude of waves through graphs.

Functional Brain Network based on the quantitative EEG data through computational and mathematical modeling. During the only day of the assessment, we will do it before (we will get this information from EEG recording during 8 minutes before do the stimulation) and after tDCS(we will get this information from EEG recording during 8 minutes after the stimulation).

Neuropsychological test to assess the adequacy of inhibitory control. During the only day of the assessment, we will do it before (after 5 minutes of EEG recording, we will start the Go/No go test keeping the EEG recording for 3 minutes, and after it we will do tDCS) and after the tDCS (after 5 minutes of EEG recording, we will restart the Go/No go test keeping the EEG recording for 3 minutes).
