Heterogeneous representations in the hippocampus

The hippocampus is essential for some types of memory, but its specific role remains conjectural. While studies on place cells have supported the hypothesis that provides a spatial substrate episodic recent engram shown optogenetic activation subset hippocampal neurons lack temporal structure spike sequences can also induce memory-associated behavior. In this short review, I discuss various lines research led to different views in memory and propose plausible interpretation findings incorporates two influential theories.
