Morris
Water Maze (MWM)
Description: The Morris Water Maze (MWM) task involves placing the rodent in a pool of water where it must use visual cues to remember the location of a hidden platform just below the water’s surface. Probe trials (transfer tests) are also used to assess the rodent’s ability to retrieve information learned in previous hidden platform tests.
Purpose: The MWM test measures spatial learning and memory. This is one of the most popular tasks in behavioral neuroscience and is sensitive to both the amnestic and memory-enhancing effects of drugs, as well as gene manipulation dependent on intact hippocampal function.
