We examined the effects of anxiolytics and anxiogenics on evaluation of learning and memory in the elevated plus-maze test in mice. Transfer latency (TL), the time mice took to move from the open arm to the enclosed arm, was used as an index of learning and memory. The TL on day 2 was shorter than that on day 1 with the maze at a height of 40 cm, and was not affected by anxiolytics and anxiogenics such as 8-OH-DPAT (0.4 mg/kg), picrotoxin (2 mg/kg), and FG-7142 (20 mg/kg), but was affected by diazepam (8 mg/kg). On the other hand, the TL on day 2 was prolonged by changing the experimental room between day 1 and day 2. TL on day 1 and day 2. TL on day 2 was prolonged by treatment with scopolamine before the trial on day 1 compared with vehicle-treated groups. This scopolamine-induced prolongation of TL was reversed by pretreatment with physostigmine and piracetam. The TL on day 2 was also prolonged by treatment with cycloheximide or normobaric hypoxia initiated immediately after the trial on day 1. The cycloheximide- and hypoxia-induced prolongation of TL were reversed by pretreatment with piracetam. These results indicate that disruption of learning and memory and its amelioration, induced by the treatments described above, can be detected using the plus-maze test, suggesting that the elevated plus-maze test could be used for evaluation of learning and memory without influence of anxiolytics and anxiogenics.
