FIGURE 3.
The effect of CE-123 administered after attentional set acquisition. CE-123 (0 or 1 mg/kg) was administered to Sprague-Dawley rats IP 30 min before the ED stage. The results represent the means ± SEM for the number of trials required to reach the criterion of six consecutive correct trials for each of the discrimination phases. N = 6 rats per group. Symbols: ∗∗∗p < 0.001 vs. ED performance in the vehicle-treated group.
