Effect of forced swimming on the memory track retention in mice with various behavioral stereotypes

摘要

The effects of forced swimming on retrieval of the passive avoidance during its extinction were found to depend on aggressive and submissive behavior. In mice without generated behavioral stereotypes, swim stress applied before or after training stabilized retention of the memory trace retrieval. The similar improved influence of forced swimming on memory storage is revealed in submissive, but not aggressive mice. The increase of resistance against extinction under the swim stress can be connected to facilitation of emotional processes.
