Figure 3. Connector hub distributions.

Figure 3.

a) Connector hubs identified in the healthy control (HC) group which correspond to ROIs with the highest participation coefficient (PC) scores across the whole brain (>1SD above the mean). b) Connector hubs identified for each variant group, top to bottom: non-fluent (nfvPPA), logopenic (lvPPA), semantic (svPPA). Compared to the HC, all three variants “lost” the left SFG and the left SPG (circled) and the bilateral S/MTG are retained (circled). On the right panel the new hubs (present in PPA but not in the HC) for each variant are shown. SFG: superior frontal gyrus, SPG: superior parietal gyrus, S/MTG: superior/middle and temporal gyri, MFG: middle frontal gyrus, MFG_DPFC: middle frontal dorsal prefrontal cortex. ITG: inferior temporal gyrus, FuG: fusiform gyrus, PrCG: precentral gyrus, PrCu: precuneus.
