Fig. 7.

A: mean (± SE) performance on the 2.0 M glucose vs. water discrimination task across training sessions for the T1R2 WT (top, ●), T1R2 KO (top, ○), T1R3 WT (bottom, ●), and T1R3 KO (bottom, ○) groups. An asterisk (*) denotes performance that was significantly greater than 50%, while an “x” denotes statistical significance that did not survive Bonferroni adjustment. B: mean (± SE) performance as a function of glucose concentration for the T1R2 KO (top, ○), T1R2 WT (top, ●), and T1R3 WT (bottom, ●) groups. None in the T1R3 KO group performed significantly above chance in the 2.0 M glucose vs. water discrimination task. C: threshold distribution for individual female (○) and male (△) mice and the means (solid lines) and SE (dashed lines) for the T1R2 KO, T1R2 WT, and T1R3 WT genotype groups.
