Figure 3

Correlations between mu ERD and the MTs (RMT and AMT). Each symbol shows one subject. The x-axis shows the RMT (left) and AMT (right). The y-axis shows the mu ERD before the tDCS. Mu ERD showed a significant correlation with the RMT (r = 0.94, p < 0.05), whereas it did not show a significant correlation with AMT (r = 0.14)
