Extended Data Figure 4

a, Design for Ca2+ imaging of neuronal overlap experiment. b, There was a significant difference in overlap across groups (one-way repeated measures ANOVA, F2,12 = 12.43, P = 0.002, n = 7 mice). There was more overlap at 5 h than 2 days (t12 = 3.03, P = 0.01) and 7 days (t12 = 4.72, P = 0.0005). c, Design for transfer of fear experiment. d, There was a significant difference in freezing across groups (one-way ANOVA, F2,43 = 3.55, P = 0.04, n = 20, 14, 12 mice). There was more freezing at 5 h than 2 days (t43 = 2.13, P = 0.04) and 7 days (t43 = 2.31, P = 0.03). e, Design for enhancement experiment. f, There was a significant difference in freezing across groups (one-way ANOVA, F2,45 = 6.38, P = 0.004, n = 22, 14, 12 mice). There was more freezing at 5 h than 2 days (t45 = 2.45, P = 0.02) and 7 days (t45 = 3.32, P = 0.002). Results show mean ± s.e.m.
