Memory retrieval before or after extinction reduces recovery of fear in adolescent rats

Extinction–retrieval improved extinction retention and reduced renewal. (A) Mean (±SEM) levels of CS-elicited freezing for retrieval 10 min before or after extinction in Experiment 3. (B) Mean (±SEM) levels of CS-elicited freezing at test in the extinction context B and the training context A in Experiment 3. Rats were in one of three groups: No Retrieval (n = 8), Retrieval–Extinction (n = 10), Extinction–Retrieval (n = 10).
