Requires the rat or mouse to swim to a platform in a pool of water. Place-learning task- subject uses visual cues in the room to locate the hidden platform. Matching-to-place task: the platform location is moved each day. Subject must remember where the new location is. Landmark-learning task- the platform is associated with a discrete cue. Designed to assess movement in the rat.
