Conditioned place avoidance Test (CPA)
Definition:
Conditioned place avoidance Test (CPA) : After different training, the mice were assigned to one of the two chambers (test chamber, blue). If the mice were in a negative valence state, they would later tend to avoid the chamber associated with this state and stay in the other chamber (reserve chamber, red), indicating that the mice chose to passively avoid the state and produce disgust.
