a Locations of the 14 spherical ROIs used for dynamic effective connectivity analysis, overlaid on a brain surface with lateral and ventral views. These included 2 ROIs in V1 [bilateral calcarine], 6 ROIs in VVS [bilateral inferior occipital gyrus (IOG), fusiform gyrus (FG), and inferior temporal gyrus (ITG)], and 6 ROIs in DVS [bilateral superior occipital gyrus (SOG), inferior parietal lobule (IPL), and superior parietal lobule (SPL)]. The nomenclature is based on Eickhoff-Zilles macro labels from N27, implemented in AFNI. All spheres had a radius of 5 mm and the center-of-mass coordinates obtained from the clusters are x, y and z in the MNI space. This panel was prepared using BrainNet Viewer [70]. b Diagram demonstrating the dynamic effective connectivity analysis workflow used to estimate the directional connectivity value from task fMRI data. Effective connectivity (EC) matrices, estimated for each time point, were pooled across task blocks of viewing one’s own face to derive the final EC estimate for each selected connection. *Note: Informed consent was obtained for publication of the volunteer’s photo in the figure.
