Place field repetition and purely local remapping in a multicompartment environment.
Bottom Line: Some studies report that place cells can disambiguate different compartments, while others report that they do not.Second, this repetition does not diminish with extended experience.Third, remapping was found to be purely local for both geometric change and contextual change.

Mentions: Place cell data (n = 104) from 10 rats were recorded from the baseline condition in the multicompartment environment, in which all compartments were identical (white). Examples of the overall firing patterns of place cells in the multicompartment environment are shown in the spike-plot montage in Figure 3. Place fields were nondirectional, as is generally the case in the open field. These cells are the subset that showed activity in the corridor. Activity of many cells was particularly intense around the doorways into each compartment (Fig. 4). Several cells showed unitary fields in the corridor, as would be expected given that the corridor was essentially a long rectangle. However, and interestingly, the firing in the corridors frequently showed a high degree of periodicity, mirroring the periodicity of the environment.Figure 3.
