Effects of MK-801 on sensitivity to the ataxic, hypothermic and sedative/hypnotic effects of EtOH in GluR1 HET and KO mice. (A) Rotarod learning. (B) MK-801 potentiated EtOH-induced ataxia regardless of GluR1 genotype. (C) MK-801 did not alter EtOH-induced hypothermia regardless of GluR1 genotype. (D) MK-801 potentiated sedation/hypnosis regardless of GluR1 genotype. n = 6 to 8/genotype/treatment. V = vehicle, MK = MK-801, WT = wild-type, HET = heterozygous, KO = knockout.
