The light-dark test measures anxiety-like behavior in rodents.
Procedure
The apparatus consists of a smaller, dark chamber connected to a larger, brightly lit chamber. The test measures the amount of time an animal spends in the more aversive, bright arena vs the “safer” dark chamber. A more anxious-like mouse is less likely to enter the brightly lit chamber, where as a less anxious-like mouse will be more willing to enter the bright open arena.
Measures
Primary: time spent in light side; latency to enter light side; number of entries into light side; average duration of visit to light side
Available Equipment
We currently have 2 light dark chambers
