Unilateral cathodal transcranial direct current stimulation over the parietal area modulates postural control depending with eyes open and closed.

These results suggest that the right parietal region contributes to static standing balance through chiefly visual information processing during the EO condition. On the other hand, L/A increase during EC and EO by tDCS over the left parietal region depends more on somatosensory information to maintain static standing balance during the EC condition.
