Effect of Transcranial Direct Current Stimulation on the Voice

Anodal tDCS will be applied at an intensity of 2mA and duration of 20 minutes. The assembly of the electrodes during the tDCS sessions will be carried out as follows: primary motor cortex, the stimulation electrode (anode) will be positioned on C5 (international EEG 10-20 system), in S1 (2cm posterior to C5), at the PFCDL (Fp3), all with the cathode positioned on the region contralateral supraorbital. For cerebellar tDCS the anode will be positioned on the inion area and the cathode on the deltoide muscle.
