Inter-region correlations of c-Fos counts and discrimination ratio (D2)

The bottom left diagonal matrix concerns data from Group Familiar (white background) while the top right diagonal matrix concerns data from Group Novel (pale grey background). r, Pearson coefficient, and correlations (two-tailed) that are significant at the 0.05(*) or 0.01(**) levels are shaded indarker grey. Abbreviations: caudPeri, caudal perirhinal cortex; lEnt, lateral entorhinal cortex; dentate gyrus, DG; CA3 and CA1.
