Materials and Methods: This study was conducted on 96 NMRI mice. Ethanol was injected intraperitoneally, while 5-HT3 receptor agonist (MCHL) was injected intra-CA1. To assess the memory, a single-trial step-down passive avoidance apparatus was used. Results: Results showed that pre-training injection of ethanol (1mg/kg), and MCHL (0.5 ng/mouse) decreased a passive avoidance memory in the adult mice. Also, a non- effective dose of MCHL (0.005 ng/mouse) with a non- effective dose of ethanol (0.01mg/kg) induced amnesia. Also, the results showed that injection of different doses of MCHL (0.5, 0.05, and 0.005 ng/mouse) combined with an effective dose of ethanol (1mg/kg) could retrieve damaged memory by ethanol. Conclusion: Findings of this study showed that the CA1 region of the hippocampus has an important role in amnesia induced by serotonin and serotonin CA1 5-HT3 receptor agonists have interaction with ethanol.
