Objective To investigate the differences of learning and memory abilities among three species of mice tested in Morris water maze.Methods Place navigation,spatial probe and working memory tests were performed to determine the learning and memory abilities of C57BL /6,Kunming and ICR mice.Results C57BL /6 mice found the hidden platform faster than other two strains of mice in the place navigation test,showing a significant difference from the 3rd day(P < 0.01).In the spatial probe test,C57BL /6 mice spent mo...
