Mean ±SEM latency to reach the platform on the visible platform task. There was a main effect of Treatment (F(3,25)= 7.49, p < 0.001), with post-hoc analyses revealing that the Harmine-high early testing animals had greater escape latencies than the Control (Fisher, p < 0.0001), and Harmine (Fisher, p < 0.001) treatment groups. Harmine-low and Harmine-high treatment groups did not differ from the Control group on latency to reach the platform (Fisher, p > 0.05).
