When moving about in space, they typically spend the majority of their time next to walls, using the tips of vibrissae to identify the wall.
For psychological security, edges are extremely important to rats. For physical security, the wall provides a distinct stimulus, helping the rat to remain on the maze, and helping recovery from a slip should one occur. A short wall, approximately 2 cm high, should be provided for physical and psychological security. Modular mazes permit many configuration from the same components ( Schenk et al., 1990). Consequently, new ideas for mazes can be implemented quickly, and traditional apparatus can be prepared easily.įor rats, the alley of a maze should be approximately 10 cm wide, a width that allows the rat to move on it easily, encourages unidirectional movement, yet allows sufficient room to turn around at the end. Mazes have the advantage of being inexpensive and easy to construct. Markowska, in Techniques in the Behavioral and Neural Sciences, 1993 6.3 Apparatus The effect on performance in the maze was attributed to the trimethyltin-induced disruption of hippocampal function, which has been shown to be important in solving this maze ( Hunsaker et al. The behavioral tendency to respond in the same manner on every problem represents a response strategy that is not optimal for solving problems in the Hebb–Williams maze. The treated animals, however, also made significantly more perseverative responses than controls. The trimethyltin-treated animals made consistently more errors on each of the 12 problems than did controls.
Rats were food deprived and given 10 daily trials for each of 12 different maze configurations. (1982) assessed the effects of trimethyltin on the ability of rats to learn the Hebb–Williams maze.

This maze consists of a series of alternative choices that can be configured to present different learning problems. Tilson, in Comprehensive Toxicology, 2010 13.21.3.2.2(ii)(f) Hebb–Williams maze
