Early Developmental Low-Dose Methylmercury Exposure Alters Learning and Memory in Periadolescent but Not Young Adult Rats

Figure 4

Methylmercury exposure altered spatial learning. Graphs show the learning curve normalized as a percentage of the latency of the group on the first day of training (mean ± SEM) at PND-40 (a) and PND-90 (b). Escape latency results were analysed using two-way ANOVA, followed by Bonferroni post hoc tests; statistically significant differences compared with the control group are indicated (; ).
