PC participation coefficient, S strength, CC clustering coefficient, LEff local efficiency, EC eigenvector centrality. A Composite of all participants’ electrodes colocalized on a single template brain. Speech arrest nodes (yellow fill) were primarily located in ventral premotor regions, but also in ventrolateral prefrontal and ventral temporal regions. Language error nodes (blue fill) were widely distributed in perisylvian regions. B Three example participant brain reconstructions. Node color (filled) represents community assignment, and node size is proportional to its participation coefficient. The outline color indicates critical nodes (blue—LE node, yellow—SA node). C Corresponding three network diagrams. The electrode position is spring-weighted (stronger connections draw electrodes closer together). Fill color indicates community, and if present, outline color indicates critical node type (LE vs. SA) D Corresponding network metrics for the three example patients. Metrics for all nodes (electrodes) for each of the three participants (n = 1 per graph) are plotted. Here, colored circles represent critical nodes; gray circles represent other nodes. Boxes demonstrate median and interquartile range, and whiskers demonstrate non-outlier maxima/minima. Source data are provided as a Source Data file.
