Transcranial Direct Current Stimulation (TDCS) represents a noninvasive method of brain stimulation that could potentially modulate such an effect. TDCS utilizes low amplitude direct currents applied via scalp electrodes to inject currents in the brain and thus modulate the level of excitability. Direct Current (DC) stimulation has been used in various forms since the inception of modern electrophysiology at the beginning of nineteenth century. There has been a recent upsurge in interest in TDCS as a tool for neuroscience research as well as an assessment and treatment modality for various neurological and neuropsychiatric disorders including depression, Parkinsonism, stroke recovery, and chronic neuropathic pain. TDCS has the distinct advantage of being inexpensive, easy to administer, noninvasive and painless. We have extensive experience with TDCS and are currently running parallel studies. We now wish to extend these principles into the visual rehabilitation domain.
