General procedures and outcomes for stress enhancement of fear learning (SEFL). Stress-induction: mice or rats receive repeated or no footshocks in context A. Single-trial fear conditioning: the next day (or weeks later) all subjects, receive a single footshock after a few minutes in a novel context B, and 24 hrs later are returned to context B to assess freezing. As depicted in the simulated bar graph, the group previously exposed to stress exhibits greater freezing than the non-stressed group in context B.
