Figure 6. Changes in spatial firing patterns and firing rates between the small and large box sessions.

Figure 6

All spatially modulated cells were included in the three analyses. Top histograms refer to the change of response between the PRE and POST epochs (before and after the removal of the small box walls). Bottom histograms refer the change between the first and second half of the POST epoch. In both cases only the area corresponding to the small box was considered. The black components of histogram bars represent the subpopulation of putative principal cells with high spatial information (SI > 0.05 bits, all the cells displayed in Fig. 4). (A) Population distribution of the rate-change index. (B) Population distribution of the shift of the COM of the firing rate maps. (C) Population distribution of the Pearson correlation between the firing rate maps.
