The maze is usually used as an enclosed maze with approximately 30 cm high walls and the entire maze is elevated to a height of 50 cm from the floor. The two-goal arms may contain a well with a food reward; alternatively, the goal arms may contain an exit tube that allows the animal to escape the maze (
Deacon 2013). Generally, there are guillotine doors at the entrance of each arm that can be used to confine the animal to a specific arm or prevent the animal from entering one of the goal arms. The maze is usually a dark color to prevent the animals from feeling extra anxiety while performing the task. Intra-maze cues can also be used to help animals distinguish and remember goal arms.
