Conditioned avoidance response test
The conditioned avoidance response (CAR) test, also known as the active avoidance test, is an animal test used to identify drugs with antipsychotic-like effects by checking if they limit the animals' will. It is most commonly employed as a two-way active avoidance test with rodents.
