Effects of scopolamine and antipsychotics on step-through latency. Animals received antipsychotic drugs, 1 h before training session. Each symbol represents mean ± SEM latency to enter the dark compartment (n = 7–8). Squares indicate latency in training session, circles indicate latency in test sessions. *p < 0.05, **p < 0.01, compared with vehicle-injected control group using Mann–Whitney U test, following significant Kruskal–Wallis ANOVA
