Fig. 2.

A: mean (± SE) performance on the 1.0 M sucrose vs. water discrimination task across training sessions for the T1R2 WT (top, ●) and T1R2 KO (top, ○), T1R3 WT (bottom, ●) and T1R3 KO (bottom, ○) groups. An asterisk (*) denotes performance that was significantly greater than 50%, while “x” denotes statistical significance that did not survive Bonferroni adjustment. B: mean ± SE performance as a function of sucrose concentration for the T1R2 WT (■) and T1R3 WT (●) groups. C: threshold distribution for individual female (○) and male (△) animals and the means (solid lines) and SE (dashed lines) for the T1R2 WT and T1R3 WT genotype groups.
