Effect of MDMA on auditory fear memory reconsolidation. (A) Experimental timeline. Rats received Saline, 3 mg/kg (3 MDMA) or 5 mg/kg (5 MDMA) of MDMA 30 seconds after exposure to a single CS. (B) Levels of freezing during auditory fear conditioning. (C) Levels of freezing before (Pre) and after auditory fear memory reactivation with a single conditioned stimulus (CS). (D) Levels of freezing during the proximal auditory conditioned fear memory test. (E) Levels of freezing during the distal auditory conditioned fear memory test. All data represent means ± SEM. #p<0.05 post tone relative to pre tone; *p<0.05 relative to all other groups.
