Polarity and timing-dependent effects of transcranial direct current stimulation in explicit motor learning

▸ Transcranial direct current stimulation (tDCS) modulates explicit sequence learning. ▸ Anodal tDCS applied during the task speeds motor learning. ▸ Anodal tDCS applied before the task slows motor learning. ▸ Cathodal tDCS slows the rate of learning in both cases.
