(A) Regression plot of the mean absolute transcranial direct current stimulation (TDCS) electric fields (EFs) within the region of interest [ROI; black outlined area in (B)], as a function of the mean absolute transcranial magnetic stimulation (TMS) EFs within the ROI. The TMS EFs were significantly correlated with the TDCS EFs. (B) Nodewise correlation between individual TDCS and TMS EFs; significant correlation coefficients are shown in color, the non-significant coefficients in gray (N.S.), and unstudied areas (average TDCS EF lower than 50% of the maximum) in brown (N.T.). The shading in the gray/brown areas represents the gyral structure of the brain (dark = sulci, light = gyri).
