Effective connectivity of region PGp. The widths of the lines and the size of the arrowheads indicate the magnitude and direction of the effective connectivity, which are shown in Table S2. PGp has effective connectivity from area 7 and intraparietal regions, and has effective connectivity directed to parahippocampal TH (PHA1-3). It is proposed that this provides a route for visuo-spatial parietal cortex regions involved in spatial coordinate transforms to provide the hippocampal system with information useful in the idiothetic (self-motion) update of hippocampal spatial representations of allocentric space. Consistent with this, PGp also receives from visual scene-related areas DVT (part of the retrosplenial scene area (Sulpizio et al. 2020)) and ventromedial visual cortex (VMV2).
