Neuroimaging and tDCS experimental setup for DLPFC (A,C) and M1 stimulation (B,D). (A,B) EEG locations are denoted in blue and follow the 10–20 locations where possible. fNIRS sources (red) and detectors (green) are shown over the left-M1 and right DLPFC with channels depicted as orange lines (M1 channels: FC3-FCC5h, FC3-FCC3h, C5-FCC5h, C3-FCC5h, C3-FCC3h, C1-FCC3h, C5-CCP5h, C3-CCP5h, C3-CCP3h, C1-CCP3h; DLPFC channels: AFF6h-AFF2h, AFF6h-F4, F2-AFF2h, F2-F2, F2-FFC4h, FFC6h-F4, FFC6h-FFT8h, FFC6h-FFC4h, FC4-FFC4h, FC4-F4) tDCS electrodes are denoted in purple (cathodes) and yellow (anodes) and follow the current values specified in Section Neuroimaging CandDBal prefrontal cortex (DLPFC [e confidence bound was >4x the size of the positive confidence bound]). Predicted electric field intensities from the maximum focality montages from the Male 1 model in the Soterix HD Targets software (Soterix Medical).
