The Effect of Timing of Transcranial Direct Current Stimulation (tDCS) for Enhancing Learning During Cognitive Training

August 11, 2014 updated by: Melissa Pigot, The University of New South Wales
This project will investigate a novel strategy for enhancing cognitive training (CT). Specifically, the investigators aim to combine a non-invasive form of brain stimulation (tDCS) with CT. This study will examine the optimal time interval - whether tDCS should be administered either before or during CT.
