[8] [26] [27] An example of place cell remapping, with the location of the place field of cell 1 changing between environment, and cell 2 losing its place field in environment 2.
Individual place cells within the hippocampus correspond to separate locations in the environment with the sum of all cells contributing to a single map of an entire environment. The strength of the connections between the cells represents the distances between them in the actual environment.
