The precision of non-associative place memory does not decline with time. A, B, Experimental design used with data presented below. A, Remote place memory in non-associative place memory test. Motility in the first 3 minutes during the learning or testing session in chamber S/Room A (white bar), or chamber C/Room A (black bar), or chamber S/Room B (gray bar). There was a significant interaction between adaptation and chamber (chamber S/Room A vs chamber C/Room A; repeated ANOVA: F_{(1, 23)} = 13.54, P < 0.01) (chamber S/Room A vs chamber S/Room B; repeated ANOVA: F_{(1, 33)} = 31.86, P < 0.001). n = 6-11/group. B, Recent (1 day: n = 9-10/group) or remote (28 days: n = 19-20/group) contextual fear conditioning memory tests. Training was carried out in the S chamber. Freezing behavior averaged over the 3-minute test sessions in chamber S/Room A (conditioned, white bars) or chamber C/Room A (novel, black bars). There was a significant interaction between day and chamber (two-way ANOVA: F_{(1, 58)} = 10.08, P < 0.01). ***P < 0.001, **P < 0.01. Error bars indicate SEM.
