The Morris water maze, created by neuroscientist Richard G. Morris, is used to evaluate learning and memory in rodents. The maze consists of a pool of water with a single circular platform raised slightly above the water’s surface. To establish working memory, the rodents are placed in different quadrants of the pool and are allowed to freely swim and search for the platform. After the first day of training, the platform is submerged, and the next several days are dedicated to finding the submerged platform. Finally, the platform is removed, and the rodents’ memory is tested. More time spent in the platform’s quadrant correlates to stronger memory retention.
