Voxel Scale Complex Networks of Functional Connectivity in the Rat Brain: Neurochemical State Dependence of Global and Local Topological Properties
Figure 5
Scatter plots of c versus k for all nodes, at the voxel scale. Overall, low degree (k) nodes were associated with a spread of clustering (c) behaviors, whereas the nodes of highest degree had clustering coefficients toward the middle of the range. Compared with vehicle (d), the active-drug networks (a–c) had a greater range in both k and c. Amphetamine and nicotine showed a differential shift in the k-c distributions between cortical and subcortical nodes, whereas for fluoxetine nodes in both brain subdivisions were shifted to higher values. The green lines indicate cutoff values used to identify nodes whose k and/or c characteristics were outside the range associated with the vehicle state (see text).
