The changes in brain networks occur dynamically in response to various contexts or external stimuli, even in a resting state [8,9,10]. In eyes-open and eyes-closed conditions, an age-related decrease in reactivity was found in alpha and beta bands [11,12]. In a resting state, EEG study path length and clustering coefficient were decreased in most of the frequency bands in elderly individuals, which was associated with a more random network topology [5]. Moreover, the variation in brain network dynamics has been linked with human learning [13], cognitive function [14], healthy aging [15,16], and mental disorders [17].
