Effects of acute administration of imperatorin (IMP; 1, 5, and 10 mg/kg) and rivastigmine (RIVA; 0.5 mg/kg, i.p) on the memory acquisition or consolidation trials using the PA test in mice. Appropriate groups of mice received saline, imperatorin (1, 5, or 10 mg/kg, i.p.), or rivastigmine (RIVA; 0.5 mg/kg, i.p) before the pretest (acquisition) or after the pretest (consolidation). Data represent the means ± SEM and are expressed as latency index (IL); n = 8–12; *p < 0.05, **p < 0.01, ***p < 0.001 versus saline-treated group; Tukey’s test
