The Functional Connectome of Speech Control
Fig 7
Functional community structure of the group-averaged networks during the resting state, syllable production, sentence production, sequential finger tapping, and auditory discrimination of pure tones.
Network modules are shown as circular groups of nodes positioned around the respective connector hubs, which are arranged on horizontal lines. Only edges passing through connector hubs are drawn, with the respective edge colors indicating the community affiliation of the target nodes. Provincial hubs are displayed as larger circles within their respective native communities. Nodal colors illustrate module membership, where colors are matched to Fig 6. Node lists on the left and right of each graph specify connector and provincial hubs, respectively. Abbreviations: 1 = area 1; 17 = area 17; 2 = area 2; 3a/3b = areas 3a/3b; 44 = area 44; 4a/4p = anterior/posterior part of area 4; 5L/5M = area 5L/5M; 6 = area 6; 7A/7P/7PC = area 7A/7P/7PC; Cbl-V/VI/VIv/VIIa/Cr1 = cerebellar lobules V/VI/VIv/VIIa/Cr1; Cu = cuneus; FG = fusiform gyrus; hIP3 = areas hIP3; IL = insula; SOG = superior occipital gyrus; ITG/MTG = inferior/middle temporal gyrus; LG = lingual gyrus; MCC = middle cingulate cortex; OP1-4 = operculum; PCu = precuneus; PF/PFm/PFop/PFt/PGa/PGp = areas PF/PFm/PFop/PFt/PGa/PGp in the inferior parietal cortex; MFG = middle frontal gyrus; THp/THpf/THpm/THt = parietal/prefrontal/premotor/temporal part of the thalamus; TP = temporal pole; R–right; L–left.
