The ventral parietal cortex includes two subregions: angular gyrus (ANG) and supramarginal gyrus/temporoparietal junction (TPJ). It has recently been proposed that the ventral parietal region showing a negative encoding success involves the TPJ rather than ANG [20]. At the same time, it has been proposed that ANG but not TPJ is associated with the DMN and the retrieval success network [26], [34], [35]. Although we clearly found evidence for an encoding/retrieval flip in overall VPC activity, it is possible that any functional differences between ANG and TPJ were obscured, since we used mean VPC cluster activity. To explore this issue further, we split the VPC region identified by the resting state scans into its two subregions by using the Wake Forest PickAtlas toolbox (http://fmri.wfubmc.edu/downloads/WFU_PickAtlas_User_Manual.pdf) and selecting “supramarginal gyrus” and “angular gyrus” (Figure 3). Next, we conducted a Region (ANG, TPJ)×Memory (Successful, Unsuccessful)×Orientation (Int/Ext) repeated measures ANOVAs for encoding and retrieval separately. As shown in Figure 3 and Table 5, besides a main effect of Region, we did not find significant interaction effects with Region during encoding. During retrieval, there was
