Consistency and dynamical changes of directional information flow in different brain states: A comparison of working memory and resting-state using EEG

Several recent studies have reported a frequency-dependent directional information flow loop in resting-state networks by phase transfer entropy, comprising an anterior-to-posterior information flow in the theta band and a posterior-to-anterior information flow in the alpha band. However, the functional roles of this information flow loop remain unclear. In the current study, we compared information flow patterns in four different brain states...
