Category: Mazes, Tracking
Atlantis System allows platforms in a Morris Water Maze to rise gently to near the surface or go down automatically, using the manual controller or TTL signals. From one to four platform systems available.
Enables extinction protocols on rats or mice. No need to stop the test to manually remove or reposition platforms.
Continuous testing, smart design
- Uniquely enables continuous testing in a Morris Water Maze test by resolving a key limitation of the Morris Water Maze task – the probe test (when the platform is removed from the pool and the rodent searches for it). Traditionally moving the fixed height platform during a trial causes an interruption and requires a new start. The Atlantis platform can be collapsed (or lifted up), quickly and seamlessly. No more hands in the water!
- All the electrical parts of the mechanism are safely located outside the pool.
- Efficiency in testing with 1 or 4 platform systems available. Up to 4 platforms are driven by the same controller. The motors can be controlled using push buttons or TTL signals.
- Atlantis hydraulic platform can also be used as a stand-alone tool, without motor/controller.
- The platform is made of clear Perspex, so it is hardly visible when immersed in the water tank.
- Use with our circular pool for the Morris Water Maze that provides connectors for attaching up to 4 platforms.

As described in the paper “The Atlantis Platform: A New Design and Further Developments of Buresova’s On-demand Platform for the Water Maze” by R.I.W. Spooner et alia, in the widely used spatial learning task of the water maze a (Morris 1981, 1984) rat (or mouse) will rapidly learn to take relatively direct paths to the platform, indicating they may have learned its spatial location.
Transfer tests, sometimes called probe tests, in which the platform is removed from the pool, offer further evidence of true spatial learning, as trained animals display a search pattern focusing on the platform location in the training quadrant.
For this reason, and despite its efficacy, the water maze task has some limitations: animals may develop strategies for finding the platform, such as circling at roughly the appropriate distance from the sidewall, which do not actually require them to learn where the platform is located, hence leading to falsely interpreted spatial learning.
To overcome these limits, the Atlantis platform was designed by Buresova et al. (1985) and validated in the above mentioned paper, proving that the platform is highly (100%) reliable and showing significantly improved localization of rats trained to the Atlantis platform compared with those trained to the regular hidden platform.
The Platform gradual rise to a position just below the water surface causes minimal behavioral disruption. The rats treat it as an escape platform in exactly the same way as the regular platform.
