Figure 2. β3-AR is involved in memory consolidation. A, Wild-type (WT) and β3-ARKO mice spent the same amount of time with a familiar object (O1) and a similar object (O1′) during object familiarization. B, Three hours after object familiarization, WT mice spent significantly more time with a novel object (O2) than a familiar object (O1) during object recognition, while β3-ARKO mice spent an equal amount of time with both O1 and O2. C, Twenty-four hours after object familiarization, WT mice spent significantly more time with a novel object (O3) than a familiar object (O1) during object recognition, while β3-ARKO mice spent an equal amount of time with both O1 and O3. Data are reported as means±SE (n=10). *P<0.01, **P<0.05 vs WT (ANOVA followed by the Student Newman-Keuls test).
