Electrode placement and electric field distribution after stimulation. (a) Stimulation sites were localized using EEG 10/20 system. Saline-soaked electrodes were placed over P3 and P4 for bilateral parietal and sham stimulation. (b) Electric field distribution on the brain induced by parietal stimulation, modeled with SimNIBS (Version 4.0.1) software at peak intensity.
