Figure 6

Mean percent freezing (± SEM) in Experiment 5 depicted for drug conditions when the drug is administered prior to immediate shock training followed by a 1 minute postshock freezing test (Panel A) and a retention freezing test 24 hours later (Panel B). Higher doses of MK-801 (0.1 mg/kg) disrupt both postshock and retention test freezing (***p<.001) while lower doses of MK-801 (0.025 or 0.05 mg/kg) only disrupt retention freezing. (**p<.05). Alternate context preexposed animals were pooled across all drug conditions.
