Summary

The purpose of our study is to explore the efficacy of combination of brain stimulation with visual rehabilitation in patients with visual field loss resulting from brain lesions. It is shown that the effect of sensorimotor training of hand can be enhanced in patients with stroke using brain stimulation. We decided to explore this combination for visual field loss because visual dysfunction following brain lesions is considered intractable. We hypothesize that combination of noninvasive brain stimulation, in the form of transcranial direct current stimulation (tDCS), with visual rehabilitation would have greater efficacy than visual rehabilitation alone.
