Open Field Experiment, model STEM-LEAR-0669-YJL is manufactured by Noldus Information Technology BV.
The open field test is a straight-forward test to investigate activity, anxiety-related behavior, and exploratory behavior in rodents. One interesting parameter is thigmotaxis; the more time the animal spends hugging the walls, the more anxious it probably is. Exploring the center of the arena, and how long it takes the animal to start doing so are used as measures of exploration or boldness.

A typical parameter in this test is thigmotaxis, which is when the animals spends a lot of time close the walls of the arena. This is seen as an anxiety-like response. Additionally, the latency to enter the center zone, or the number transitions and the time spent in different zones are of interest. EthoVision XT easily measures these parameters.
