Figure 1: Reinstatement of a specific event representation in cortico-hippocampal networks.

Figure 1:

The process of recalling a particular event or episode often begins with the construction of a situation model, here a birthday dinner at a restaurant. We propose that such a situation model, informed by your schemas of a birthday celebration and dining at a restaurant, are constructed by posterior-medial cortical areas (blue). The situation model is populated with local entities, such as drinks, snacks, friends, and a table. We propose that these local features are represented in anterior-temporal cortical areas (red). Through interactions with the hippocampus, these two cortical networks are able to sharpen their activity patterns into a representation of a specific event such that specific people, foods, and drinks are recalled in a particular arrangement at a particular table and a particular restaurant. Moreover, the hippocampus facilitates the integration of information across the two networks.
