The effects of fluoride exposure from adolescence to adulthood on Morris’s water maze performance of mice. (A) and (B) show the escape latency time (ELT, seconds) in the first and fourth training sessions, respectively. (C) shows the arrival latency time (ALT, seconds) in the target quadrant (Q4). (D) shows the time spent (seconds) in the target quadrant (Q4). Different letters indicate a significant difference (p < 0.05, one-way analysis of variance with Tukey’s post hoc test).
