Fig. 2. Pyramidal cells in CA1 and CA2/3 cliacriminate between contexts.
a, Activity difference scores (see Methods) between novel and familiar contexts for all cells (two-sided signed rank-sum test: novel versus familiar activity). b, Mean spatial information of active cells (two-sided rank-sum test). c, Familiar-trade place cell activity plotted for the first (left) and second (middle) block of familiar-context runs and for the novel context (right). d, Mean activity correlations of place cells within familiar (left) and novel context (middle) runs and between contexts (right bars; ANOVA on ranks, Dunn's test). e, PoV correlations (see Methods) for all experiments within familiar-context runs and between contexts (thin lines). Thick lines denote mean ±s.e.m. (two-sided paired t-test). Boxes, 25th to 75th percentiles; bars, median; whiskers, 99% range. *P < 0.05, **P<0.01, ***P<0.001; NS, not significant. For exact P values see Supplementary Table 1.
