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

Retrieval–extinction improved extinction retention and reduced renewal. (A) Mean (±SEM) levels of CS-elicited freezing during conditioning in Experiment 1 (n = 12 for both groups). (B) Mean (±SEM) levels of CS-elicited freezing for retrieval–extinction in Experiment 1. (C) Mean (±SEM) levels of CS-elicited freezing at test in the extinction context B and the training context A in Experiment 1.
