Schematic illustrations of common and distinct effective connectivities for processing upright and inverted faces. Red arrows indicate positive connections. Blue arrows indicate negative connections. The connections were visualized with the BrainNet Viewer (Xia et al., 2013; http://www.nitrc.org/projects/bnv/). A, Common connectivity for upright and inverted face processing. B, Distinct connectivity for upright face processing. C, Distinct connectivity for inverted face processing.
