Effect of Transcranial Direct Current Stimulation in Altered States of Consciousness

"Time A: Behavioral assessment using the Coma Recovery Scale-R (CRS-R). · Time B:~Transcranial Direct Current Stimulation (tDCS). Frontal stimulation for 20 minutes with the anode placed on the international electrode position and the cathode on the right supraorbital region. Stimulation will be repeated once a day, 5 days a week, for 4 weeks. · Time C. Behavioral assessment using the Coma Recovery Scale-R (CRS-R). Rest Period: 2 months."
