Neural community architecture of the group networks during syllable and speech production. (a,d) Group connectivity matrix of the SylPN and SPN showing the neural communities identified by the Louvain community detection algorithm. Each cell of the matrix represents the strength between two nodes in the group network. (b,e) Community structure of inhibitory nodes of the SylPN and SPN. (c,f) Community structure of excitatory nodes of the SylPN and SPN. Inhibitory and excitatory neural communities are visualized on three-dimensional brain renderings using BrainNet Viewer software.
