Cincinnati Water Maze

Product Code:42500
Category: Mazes, Tracking

The Cincinnati Maze (9T-maze) is an evolution of the Biel Maze with an increased number of interconnected T-mazes.

It is most commonly used as a water maze to avoid scent issues and is used on rats to study egocentric navigation (memory). In order to avoid any possibility of external cue use, the maze is constructed in IR-transparent Perspex to run the experiment in full darkness and ensure that movements are due to egocentric and not allocentric mechanisms.

This product warranty can be extended up to 24 Additional Months.

The Ugo Basile Cincinnati Maze for rats is a 2x2 mt arena with a training corridor and 9T-mazes interconnected. It is filled with water, has drain and overflow included, together with wheels for easy movement.

The materials used are transparent with IR illumination, to ensure experiments in the darkness. IR-transparents lenses, IR-sensitive cameras and ceiling IR illumination systems can also be provided with Video-Tracking software.

The ability to learn and remembering different locations is encoded in the brain by two systems: one which uses external cues (allocentric) and one using internal cues (egocentric. The structures of the brain involved in the two types of memory are different and hence the ability to run tasks that can dissect them is important. Through the asymmetrical T-mazes which constitute the Cincinnati maze, the number of errors to reach the goal, the time and distance spent are measured to get an index of such memory and ability after an initial training period. Applications are many, from Alzheimer to epilepsy and all those neural phenomena which involve spatial memory, especially when the areas of the brain governing egocentric navigation are to be investigated. An advantage versus the more commonly used Water Maze is that it focuses essential on external cues and it is not possible to count the number of errors as endpoint.
