Fear memory impairing effects of Ro 25-6981 on multi-trial, one-trial and low-lock shock fear conditioning. (A) Schematic of the multi-trial high shock protocol. (B) Pre-training treatment with 10 mg/kg Ro 25-6981 reduced fear recall relative to vehicle (0) (n=16–18/dose). (C) Schematic of the one-trial high-shock conditioning protocol. (D) Pre-training treatment with 10 mg/kg Ro 25-6981 reduced fear recall relative to vehicle (0) (n=13–14/dose). (E) Schematic of multi-trial low-shock protocol. (F) Pre-training treatment with 10 mg/kg Ro 25-6981 reduced fear recall relative to vehicle (0) (n=15–16/dose). **p<.01, *p<.05 vs. vehicle (0). Data in Figures 1–4 are Means ±SEM.
