Fig. 1: MST visualizations.
From: Functional brain networks in the schizophrenia spectrum and bipolar disorder with psychosis
a–c Brain regions and their connections are visualized as nodes (circles) and edges (lines). Red nodes are leaf nodes with only one connection. a Path-like MST with a diameter of twelve edges. b Intermediate between a path-like and a star-like MST with a diameter of six edges. The green node has a higher degree (five connecting edges) than the red leaf nodes. c Star-like MST: The green node is a node with high betweenness centrality: When connecting any two nodes in the network you have to pass the green node. Kappa, a measure that characterizes the degree distribution, is highest for a, intermediate for b, and lowest for c.
