Fig. 1.

Seven-week old mice were subjected to right carotid artery exposure and 75 db noisy environments. They were started to be tested by Barnes maze and fear conditioning at one week after being exposed to various experimental conditions. A: Performance during the training sessions of Barnes maze test. B: Performance during the memory phase of Barnes maze test. C: Performance in fear conditioning test. Results are means ± S.E.M. (n = 15). * P < 0.05 compared with the corresponding data on day 1, $ P < 0.05 compared with control on corresponding day, ^ P < 0.05 compared with control, # P < 0.05 compared with surgery group.
