  • We investigated the contribution of locomotor activity and learning and memory abilities to Alzheimer’s disease induced by metal neurotoxicity. The metal neurotoxicity model was established by using locomotor activity tests and activity-avoidance conditioning paradigms, and observing changes in zebrafish behaviors after exposure to 50 μg/L of AlCl3 with different pH values (pH 7.8, pH 6.8 and pH 5.8) for 24 hours and 96 hours. The results showed Alzheimer’s disease-like behavior in locomotor activity tests and activity-avoidance conditioning paradigms by zebrafish receiving AlCl3in pH 5.8 significantly decreased compared to the control group and groups receiving AlCl3in pH 7.8 and pH 6.8 for 96 hours and 24 hours. These results provide evidences that exposure to AlCl3in an acid environment can influence locomotor activity and learning and memory abilities in zebrafish. In addition, exposure time and concentration of Al induced neurotoxicity and damaged the brain area of memory, resulting in Alzheimer’s disease-like behavior.
