Abstract

A sense of the next place Place cells in the hippocampus track an animal's position in its environment. Previous work contends that sequential place-cell maps are produced during the first visit to a new area, and later consolidated at rest or during sleep. George Dragoi and Susumu Tonegawa report that place-cell firing patterns occur during rest or sleep before a novel spatial experience. They call this 'preplay', and because these sequences are distinct from the replay of previous experience, they suggest that it serves to prepare cell assemblies for any novel encoding that may occur in the near future.
