Group means of Global Connectivity Index in four EEG bands during Session-1 (before COVID-19 pandemic). Between-group differences in all bands were significant (p < 0.01, ANOVA followed by Tukey post-hoc test). GCI was calculated as the averaged phase locking value (the measure of connectivity was based on the phase of the EEG signal) in the four canonical EEG bands: theta (4-7 Hz), alpha (8–12 Hz), beta-1 (14–20 Hz) and beta-2 (21–30 Hz). Created using MATLAB 2020a (The MathWorks, Inc, www.mathworks.com).
