Comparisons of the magnitude and current intensity of the SCD-dependent TMS-induced E-fields in normal controls (NC) and Parkinson’s disease (PD) patients. Data are displayed as mean ± SD. (A) The magnitude of the E-fields was measured as the 95% (yellow), 99% (orange) and 99.9% (Emax) (red) of the strength of simulated E-fields. The early-stage PD patients showed significant decreased Emax (V/m) (NormE) (B) and current intensity (NormJ) (A/m2) (C) in Target 3 (EEG F3), Target 6 (Rusjan Target) and Target 7 (BA46 centre).
