Conventional network and MST findings. Conventional network measures (A) normalized clustering and (B) normalized path length were compared between groups. MEG obtained cortical functional networks were characterized by significantly lower normalized clustering (delta, theta, alpha1, alpha2, and gamma band) and lower normalized path length (theta band), indicating that these networks are shifted towards random networks [Watts and Strogatz 1998]. The MSTs of MS patients were characterized by (C) lower leaf fraction (delta, theta, and alpha2 band) and (D) lower degree divergence (delta, theta, alpha1, and alpha2 band). This suggests that the MSTs of MS patients are shifted towards more path‐like trees (Fig. 5). [Color figure can be viewed in the online issue, which is available at http://wileyonlinelibrary.com.]
