Morris water maze cued platform trials. Animals administered MA had increased latencies to reach the platform on day 1, F(1, 36) = 4.26, p<0.05. On the remaining days, there were main effects of treatment, F(1, 36) = 12.27, p<0.01, day, F(4, 144) = 31.80, p<0.0001, and treatment × day F(4, 144) = 5.05, p<0.001, for latency. The treatment × day interaction was due to increased latency in MA-treated animals on day 2 (p<0.0001) and 3 (p< 0.001). On days 4–6, latencies were similar to controls. **p< 0.01, ***p< 0.001
