Head model, brain segmentation, and cerebral cortex dipole. (a) Standard head model and spatial distribution of 60 EEG electrodes on the scalp. (b) The cortical surface is segmented into 256 anatomical regions of interest (128 regions per hemisphere) based on a random homogeneous segmentation method. (c) Distribution of network nodes of 256 cortical layer regions after downsampling.
