Conclusions from a behavioral aging study on male and female F2 hybrid mice on age-related behavior, buoyancy in water-based tests, and an ethical method to assess lifespan

Figure 4. Learning and memory assessed by shuttle box passive avoidance test. Data are presented as the time it took to enter the conditioned area on the testing day (Day 2) subtracted by the time to enter on the conditioning day (Day 1), calculated for each individual animal, and indicate no major age or sex difference (pM7-F7=0.055, pM15-F15=0.97, pM22-F22=0.74, pM7-15=0.11, pM7-22=0.23, pM15-22=0.19, pF7-15=0.62, pF7-22=0.30, pF15-22=0.60; Mann-Whitney). Values are mean ± SEM; nM7=7, nM15=10, nM22=10, nF7=9, nF15=12, nF22=7.
