Summary

Motor learning occurs with structural and functional modifications in neural networks that meet a certain demand. The improvement of performance in diverse activities is a measure of learning, as well as the generalization and transference of this capacity. Transcranial direct current stimulation (tDCS) is a modulation technique of brain activity that modifies cortical excitability, causing changes in motor evoked potentials that influence motor learning. Modifications similar to the long-term potentiation, essential for learning processes, have also been described after applying tDCS. The primary motor cortex is the area of stimulation where there is more robust evidence in favor of increased motor learning. PURPOSE: to investigate the effects of anodic tDCS on the learning of sequential finger movements in young and healthy individuals.

Interventions

DEVICE

Transcranial Direct Current Stimulation

Anodic tDCS during 20 minutes ON, intensity 2milliamps, on the contralateral motor cortex of the trained hand simultaneously with the motor training. The cathode (negative electrode) will be positioned over the contralateral supraorbital region. It wil be used rubber electrodes covered by a vegetal electrode embedded in saline solution, physiological saline, measuring 5 x 5 cm (25 cm2).

OTHER

Simulated

Simulated anodic tDCS (only 30 seconds ON), intensity 2milliamps, on the contralateral motor cortex of the trained hand simultaneously with the motor training. The cathode (negative electrode) will be positioned over the contralateral supraorbital region. It wil be used rubber electrodes covered by a vegetal electrode embedded in saline solution, physiological saline, measuring 5 x 5 cm (25 cm2).
