Mean (±SEM) latency to find the platform (A,B) for short-term (A) and long-term (B) spatial memory in the Formalin or Control male and female rats for the early (P26-34) and late (P45-53) age groups. Differences in latency between short-term and long-term memory were found in the Control male and female rats of the early age group and in females of the late age group. Formalin vs Control rats; differences between short- and long-term memory: in latency, ∧p < 0.05, &&p < 0.01, in Control P26-34 males and females, and $$p < 0.001, in Control P45-53 females. The number of the rats in the groups corresponds to the number of rats in the groups in Figures 1, 2. The graphs on the right illustrate significant results of statistical analysis. ∗p < 0.05 significant effect of exposure.
