Addis and Schacter (2012) suggested that three different simulation-related processes rely to some extent on the hippocampus: (1) providing access to details stored in memory that are relevant to a constructed scenario, (2) recombining these details into a spatiotemporal context, and (3) encoding a simulation into memory so that it can influence and guide future behaviors. Addis and Schacter (2012) further noted that these processes might depend on regional differences within the hippocampus, which could also be relevant to some of the inconsistencies noted in the literature.
