Place field repetition and purely local remapping in a multicompartment environment.

Spiers HJ, Hayman RM, Jovalekic A, Marozzi E, Jeffery KJ - Cereb. Cortex (2013)

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.

Analysis of dwell times and compartment re-entries in context-change trials and in the follow-up baselines. (A) Dwell time increased markedly in the compartment that was changed (black bar), whereas in the following trial, dwell time was not different in any of the compartments (including the had-been-changed one). (B) Compartment re-entries, broken down by trial quadrant. In the context-change trial (left column), re-entries increased markedly in the changed compartment (red bars), though this declined across the course of the session as the animals habituated to the change. In the follow-up baseline (right column), there was no difference in re-entries into any of the compartments, including the had-been-changed one.

BHT198F2: Analysis of dwell times and compartment re-entries in context-change trials and in the follow-up baselines. (A) Dwell time increased markedly in the compartment that was changed (black bar), whereas in the following trial, dwell time was not different in any of the compartments (including the had-been-changed one). (B) Compartment re-entries, broken down by trial quadrant. In the context-change trial (left column), re-entries increased markedly in the changed compartment (red bars), though this declined across the course of the session as the animals habituated to the change. In the follow-up baseline (right column), there was no difference in re-entries into any of the compartments, including the had-been-changed one.

Mentions: The dwell times for the various conditions are shown in Table 1 and Figure 2. Change of the compartment from white to black caused a significant increase in dwell time, from a baseline average of 132 to 218 s (Fig. 2A). A 2-way ANOVA of compartment type against remapping condition showed a main effect of compartment type [F3,48 = 8.50, P < 0.001] and a significant interaction of trial type against compartment [F6,48 = 5.97, P < 0.001].Table 1
