Labyrinthe en croix surélevé

Elevated Plus Maze: Test to measure anxiety in laboratory animals and also commonly used to test different anxiolytics.

Scientific Interests

The test creates an approach-avoidance conflict in rodents  between the natural desire to explore novel environments and his fear of open spaces (which put him at the sight of predators). The maze has two closed and two open corridors (without walls). Anxiety is measured by the time spent by the animal in exploring the 'open' arms. We can conclude that an animal is more anxious, less time he spent in the open arms .

Available rat and mouse.

We realize your own maze! (color, dimensions,...)
