IR-transparent mazes for video-tracking
Ugo Basile Infrared transparent mazes offer the highest contrast for the best video-tracking performance, empowering your behavioral experiments.
Antidepressant drugs and depression animal model genetic screening are commonly conducted by using the Tail Suspension Test (TST). This test is based on the aversive effect of hanging a mouse of rat by the tail, which elicits its struggling moving upwards in an attempt to escape (which is obviously not possible).
The struggling attempt tends to be shorter in duration and translates into animal immobility in depressed animals and recovers by use of antidepressants. The test is video-tracking based by measuring in one or multiple animals the immobility during the test. The Ugo Basile system comes complete with a U-shaped chamber to run more animals at the time and a hook where the animal is kept hanging. The camera positioned in front of the chambers detects the immobility in multiple animals simultaneously.

The animal is kept hanging by its tail at about 10 centimeters from the ground for about 5 minutes. During this time the animal tries to escape showing a a tail climbing behavior, until a behavioral despair occurs. The tail climbing is longer in animals which are not depressed or that have been given anti-depressant drugs, so that the measurement of immobility gives an indication of the depression state of the animal.
The translational power of the test has been questioned because the human depression condition is a long-lasting condition, while the TST test is a short experiment. For this reason, some prefer to use it as a tool to measure antidepressant effects of drugs, rather than a proxy for depression states.
In any case the TST, together with the Porsolt Forced Swim test are still the most used test to assess depression in rodents, as shown by the amount of citations exceeding 50,000.
