Modulating the brain at work using noninvasive transcranial stimulation

► We provide a review of noninvasive brain stimulation literature aimed at enhanced cognitive skills. ► We summarized underlying physiological mechanisms induced by noninvasive brain stimulation. ► Our evidence suggests vigilance can be preserved with transcranial direct current stimulation. ► Neuroergonomics researchers should strive to apply tDCS and TMS techniques to complex tasks.
