(A) The details of electrical stimulation of the right IFG are shown, displayed from three slices: Coronal slice, Sagittal slice and Axial slice. The redder the colour, the higher the activation. And the theoretical current intensity on the right IFG is predicted with Soterix HD-Explore software. The software name is HD-Explore, brand is Soterix Medical, and version is 5.0. (B) A cap for multibrain stimulation combined with real-time signal acquisition was designed and applied in this study. We used nondeforming plastic tape to hold the optode patch in place to sustain the relative distance between the adjacent optodes or electrodes (ZL 2022 2 3443116.1). (C) The arrangement of optodes and electrodes. Four channels and five current electrodes around FC6 were placed to modulate or measure activity in the right IFG, and the other 10 channels were placed adjacent to the Fpz to measure activity in the frontal pole region. The red circles indicate the positions of anodal electrodes, and the blue circles indicate the positions of cathodal electrodes; the specific intensities of the five electrodes were FC6 (1.5 mA), F6 (− 0.37 mA), FT8 (− 0.38 mA), C6 (− 0.37 mA), and FC4 (− 0.38 mA).
