Effect of Aging on the Performance of the Radial Six-arm Water Maze Task in C57BL/6 Mice / 医学研究杂志

Objective To explore whether there is the decline of learning and memory ability in C57BL/6 mice in radial six-arm water maze (RAWM) task. Methods The RAWM task was used to test the spatial abilities of learning and memory. Results All of old mice showed the decline of spatial learning and memory ability in the RAWM task. Conclusion RAWM task is excellent spatial learning and memory task and is sensitive to measure the age-related decline of learning and memory ability in C57BL/6 mice.

Effect of Aging on Nonspatial Learning and Memory Ability in C57BL/6 Mice / 医学研究杂志

Objective To explore the effect of aging on nonspatial learning and memory ability or recognitive memory ability in C57BL/6 mice.Method The C57BL /6 mice were used and novel-object recognition task was used to test the recognition memory ability.Results There was hardly exploring behavior in half of mice in the novel-object recognition task.Conclusion The novel-object recognition task is valueless to evaluate the effect of age on the nonspatial learning and memory ability in the C57BL/6 mice.
