ABSTRACT

How are these memory capacities mediated within the circuitry of the hippocampus? Recent observations from extracellular recordings in behaving animals suggest that hippocampal neuronal networks might represent sequences of events and places that compose episodic memories. The content of information encoded by the firing patterns of these neurons includes both specific conjunctions of events and places unique to particular experiences and features that are common to overlapping experiences. Indeed, there is now evidence that the hippocampus creates separate but linked, episodic-like representations even when the overt behaviours and places where they occur are the same but the events are parts of distinct experiences.
