Resting‐state functional connections revealed by EEG‐alpha power spectra, compared between EC and EO states. (A) Significantly enhanced connections of DAN between frontal and parietal regions (anterior to posterior) are demonstrated during the EO state, compared to the EC state. The significantly enhanced connections in the EO state (75%) are depicted, more than those connections in the EC state (50%). (B) Statistically significant connections of DMN, DAN, and visual networks are depicted by top 15%, 10%, 8% pairs of z scores, compared EO with EC state (two‐tailed t‐tests, Bonferroni corrected). Visual networks are enhanced in the parietal, occipital, and occipitotemporal regions in the EO state. Increased connection strength between medial prefrontal cortex and precuneus regions, strong DMN in the EO state, is still noted in line with Yan et al. [2009]. The significantly decreased functional connectivity among left precentral, right precentral, and cuneus from EC to EO state ensures that the improvement of intrinsic networks' activity does not come from the general improved signal‐to‐noise ratio between states.
