Alteration of time spent and distance around the platform and during the memory retention test in the water maze. Four trials were conducted on the fifth day without the platform and the search latency (A) and distance (B) were measured. Data are presented as mean ± SEM, and comparisons between the two groups were made using the unpaired t-test. *P < 0.05, compared to the drug treated-hPS2 transgenic mice.
