BaP exposure accelerated progressive spatial and working memory decline in the Morris water maze test. a Escape latency during 5 days training performed immediately after BaP exposure for 1 month or 1 month after 2-month BaP exposure. b Representative path maps of each group in the probe trail. c Latency to the first entry to the target quadrant in the probe trail. d Time spent in the target quadrant in the probe trail. e Entries to the platform quadrant in the probe trail. N = 10/group. Data are mean ± SEM, *P < 0.05 and **P < 0.01 compared with WT-Vehicle control; ^#P < 0.05 compared with WT-BaP group
