A schematic illustration of the contrast minimum spanning tree (MST) network between the pre-test and post-test conditions. MST network is constructed with adjacent matrix of phase lag index (PLI) of electrode pairs. Network integration properties are characterized with MST variables (leaf fraction, maximal betweenness (BWmax), and tree hierarchy (TH))
