Application of transcranial direct current stimulation in the visual system
Main Article Content
Abstract
The visual system may undergo both induced and spontaneous neuroplastic changes. Transcranial direct current stimulation is a method that allows direct modulation of the excitability of the cerebral cortex in humans and animals. Results from studies demonstrated beneficial effects of the method in the modulation of the excitability of occipital cortex of the brain. The use of transcranial stimulation enables improvement of visual functions, including enhanced quality of vision in amblyopia and stereoscopic vision. This article aims to characterize the method as adjunctive therapy, indicating its application in the treatment of the visual system.
