The Marquee Water Maze is an escape maze. It is circular pool with a clear Plexiglas circular wall. It was used to show that there’s no evidence for cognitive mapping in rats.
Centered inside the pool was a kind of marquee which divided the available space into an inner pool surrounded by a peripheral channel. It was a metallic cylinder with an interior painted uniformly white, open over 90 on all its height and surmounted by a cone-shaped opaque white plastic roof.
This marquee could be turned horizontally around its center so that the opening could be set at different orientations. The rats’ movements in the inner pool were monitored by means of a video camera set just above the top of the roof.
A white cylinder served as an escape platform. This hidden goal was located in the inner pool, 30 cm from the pool center.
