Recall of fear is partially state dependent with nimodipine. A, Experimental design (8 mice per group; between-subjects design). B, Freezing during the two cues that preceded each shock for mice injected with nimodipine (16 mg/kg, 20 min pretreatment; n = 16) or vehicle (n = 16). Freezing 24 hr later during a 2 min CS test, 20 min after drug or vehicle injections. One-half of the mice from each of the treatment groups of the previous day received nimodipine (16 mg/kg) or vehicle. *p < 0.05 versus 0–0 group; +p < 0.05 versus 16–0 group.
