Results and Conclusions： 1. In the 8 papers reviewed in this paper, recognized experimental rat produced 22-kHz USV calls in the followed 3 different aversive condition. 2. Rats produced 22-kHz USV calls in the withdrawal of drug, fear conditioning and chronic pain. The 22-kHz USV calls divided two different patterns which short and long 22-kHz USVs in the withdrawal of drug.
