FIGURE 2.

Effects of sub-chronic bergapten or saline administration on the latency index (LI) during the acquisition trial (A) and consolidation trial (B), using the PA test in mice. Bergapten (12.5 and 25 mg/kg, i.p.) or saline were administered for the 6 days. On the seventh day bergapten was administered 30 min before the first trial (A) or immediately after first trial (B) and mice were re-tested 24 h later; n = 8–10; the means ± SEM; *p < 0.05; ***p < 0.001 vs. saline-treated control group; Tukey’s test.
