These Morris Water Maze videos were recorded by Jean-Etienne Poirrier at the Cyclotron Research Center (University of Liege, Belgium).

Morris Water Maze movie of a rat that doesn't find the platform (it is its first training session). The rat is detected by the video tracking system (Noldus Ethovision) and shown in red. The path following the rat is also in red. There are four quadrants: North, South, East and West. They are separated by "virtual" blue lines (i.e. drawn by the tracking system). The platform is located in the North quadrant and is represented by a blue circle.

Technical data

All these videos are encoded in MPEG format. You should be able to watch them in any movie players. But please note that these videos need the Techsmith video codec in order to be played on MS-Windows (with Windows Media Player, WinAmp, etc.). You can download them here (choose "Download TSCC Codec").

If you are running GNU/Linux, you shouldn't have any problem: mplayer can play these videos (other players can too).

Respect your experiment animals!

I want to stress the point that all the experiments were done with the agreement of the University ethical committee. I pay the best attention and give the best care I can to the animals I am using in all my experiments.

If you can read French, you may find this presentation interesting: "Notions de bien-être animal" (animal wellfare).
