1. Figure 1 Decrease in neuronal activity during n-back task in real tDCS as compared to sham stimulation. (A) Main effects of group (sham > real) based on whole brain analysis contrasting 1, 2, 3 versus 0-back; decrease in neuronal activity in the cerebellum during the n-back assessment in the real t-DCS, as compared to sham stimulation. (B) Cerebellar response with increasing working memory load during n-back assessment; mean beta values and standard deviations.
