Cerebellar tDCS on Motor Learning of Healthy Individuals

Current will be applied by a DC stimulator (NeuroConn Plus, Germany).The active electrode (anode: 5x7 cm²) will be placed over the left cerebellar hemisphere (3 cm lateral to the inion) and the reference (5x7 cm²), over the left arm with current intensity of 2mA, fade in and fade out of 10 seconds, during 20 minutes.

Current will be applied by a DC stimulator (NeuroConn Plus, Germany). The active electrode (cathode: 5x7 cm²) will be placed over the left cerebellar hemisphere (3 cm lateral to the inion) and the reference (5x7 cm²), over the left arm with current intensity of 2mA, fade in and fade out of 10 seconds, during 20 minutes.

Sham ctDCS (NeuroConn Plus, Germany) will be applied at the same parameter settings used on cathodal ctDCS however, current duration will be only 30 seconds. Moreover, device automatically turned off without volunteer's perception, but volunteers will be with electrodes montage for 20 minutes.
