The Morris Water Maze (MWM) is an experiment used to evaluate the spatial learning and memory abilities of mice or rats. In the experiment, animals were placed in a water-filled circular pool with a potential underwater platform. Through learning and memory, the animal needs to find and remember the location of this platform. After multiple trials, the animals' swimming path in the pool and the time it takes to find the platform are observed to evaluate their spatial cognition and learning abilities. MWM is widely used in neurobiology, drug evaluation, and neurodegenerative disease research.
