Abstract

The Classic Labyrinth Test (CLT) is a simple way to evaluate behaviors in rodents such as learning ability, memory, and anxiety. The protocol presented here describes the procedure for use with rats, but the protocol can also be adapted for use in mice if a smaller device is used. In short, the CLT uses a square-shaped maze with a starting point and a stopping point. After the animal is trained, the animal is allowed to view and explore the labyrinth freely for 10 min. During this time, all of the animal's vertical and horizontal movements within the labyrinth are recorded. This is a very challenging task because it requires the animal to remember the quickest path between the starting points and the end. In cases where the labyrinth is designed so that the animal only needs to walk forward, it is quite easy for healthy rats, but for rats exposed to neuro-xenobiotics (drugs, pesticides) there will be disturbances in their path. Researchers use many different versions of this test and the procedure for each version can vary significantly. Here, we present a working protocol that enables the detection of traces of some toxic substances that may be exposed to individuals over a long period and in very small amounts under specific conditions such as drugs, medicines and pesticides.
