On-Demand Water Maze (Atlantis) Platform


ENV-595M Mouse On Demand Water Maze Platform
ENV-595R Rat On Demand Water Maze Platform

System Highlights

  • Submersible platform that raises when the animal swims over the appropriate location
  • Can be used to improve spatial search strategies
  • Rat and mouse sizes available

The On-Demand platform, sometimes called the “Atlantis Platform” (Spooner RI, Thomson A, Hall J, Morris RG, Salter SH. The Atlantis platform: a new design and further developments of Buresova's on-demand platform for the water maze. Learn Mem 1: 203-211, 1994), has been used to dissect search strategies based on spatial learning in the water maze task. The On-Demand platform differs from the standard water maze platform, in that the On-Demand platform remains submerged well beneath the water surface until the animal remains in a defined region for a specified time, at which point, the platform raises and provides an escape surface for the animal. Probe trials conducted with the On-Demand platform can minimize confounds due to extinction and non-spatial learning, such as the animal swimming a certain distance from the wall.

Med Associates offers On-Demand water maze platforms suitable for either mouse or rat studies.

As with all of our water maze platforms, the On-Demand platforms feature a textured surface that provides traction for the animal to grip on to while climbing on the platform.

Specifications

  • Operated by 28V DC Logic signal; platform remains lowered while the 28V signal is applied, and platform raises when the 28V signal is turned off. TTL to 28-volt converters are available.
