The basic procedure for the Morris water navigation task is that the rat is placed in a large circular pool and is required to find an invisible or visible platform that allows it to escape the water by using various cues. Many factors can … See more

The Morris water navigation task was conceived by Richard G. Morris (then at the University of St Andrews) in 1981 as an alternative to the radial maze. The test was developed to study spatial learning and how it differed from other forms of associative learning See more

Like other spatial tasks, such as the T-maze and radial arm maze, the Morris water navigation task is supposed to measure spatial memory, movement control, and See more

The earliest measure of learning is escape latency, which is the time it takes to find the platform. However, this measure is confounded by swimming speed, not necessarily a … See more

When the searching times for the platform in the target quadrant are reduced in the probe trial, this is seen as direct evidence that the spatial memory of the rat must be impaired. However, … See more
