Organization of Excitable Dynamics in Hierarchical Biological Networks
Figure 3
Construction of a color-coded topological reference which is based on the location of the CN in the network (top row), and computation of the dynamic clustering tree is carried out as described in Figure 2 (bottom row).
(Top row) The central node h (inner circle in the graph representation) displays the highest betweenness centrality B (see Methods: betweenness). It is surrounded by modules of equidistant nodes (from h). The nodes of the resulting distance vector are re-sorted according to their distance to h.
