Table 3 Results of univariate ANOVAs of group (water or 32% sucrose) by genotype (WT or Gria1 −/−), showing main effects of group and genotype, and the group x genotype interaction, for six measures of consumption behaviour in Experiment 3.

From: GluA1 AMPAR subunit deletion reduces the hedonic response to sucrose but leaves satiety and conditioned responses intact
