Upper panel, “A”: Mean number of active lever presses during the footshock-induced reinstatement test session as a function of AV411 dose. Brackets through the bars indicate ±S.E.M. “VEH” = results of the vehicle-treatment group. Dashed horizontal lines indicate the range of the means of active lever presses across dosage groups occurring during the last session of extinction. Asterisks (*) indicate significantly different (P<0.05) from vehicle. Lower panel, “B”: Mean number of inactive lever presses during the footshock-induced reinstatement test session as a function of AV411 dose. Other details as in the upper panel.
