Repetitive Anodal TDCS to the Frontal Cortex Increases the P300 during Working Memory Processing
Brain Sci. 2022 Nov 14;12(11):1545. doi: 10.3390/brainsci12111545.ABSTRACTTranscranial direct current stimulation (TDCS) is a technique with which neuronal activity, and therefore potentially behavior, is modulated by applying weak electrical currents to the scalp. Application of TDCS to enhance working memory (WM) has shown promising but also contradictory results, and little emphasis has been placed on repeated stimulation protocols, in which effects are expected to be increased. We aimed to characterize potential behavioral and electrophysiological changes induced by TDCS during WM training and evaluate whether repetitive anodal TDCS has a greater modulatory impact on the processes underpinning WM than single-session stimulation.
