Neurosciences. A maze developed by the neuroscientist Richard G. Morris in 1984. The Morris water maze is used to test spatial memory in rats or mice in a behavioral experiment.
The maze consists of a pool of water usually 1.5 to 2 meter in diameter and 0.5 meter deep and an escape platform hidden a few millimeters below the water surface. When a rat is released, it swims around the pool in search of an exit until it finds the platform. The animal is trained on four consecutive days and is able to locate the platform more quickly. The escape
latency, i.e. the time of finding the immersed platform is measured (spatial learning). On the fifth day the platform is removed, the animal is released in the water and the time it spends at the former platform location is measured (sustainability and precision of the spatial memory).
