FIGURE 4.

Whole-nerve responses to Suc, Glc, saccharin and SC in the chorda tympani nerves of T1R3-KO mice. Response to 0.1 mol/L NH₄Cl was used as a unity (1.0). Values indicated are means ± SE. Results of unpaired t test for the effect of the addition of 10 mmol/L NaCl and the effect of 1 mmol/L phlorizin (Phl) on responses to taste stimuli are shown in Table 4 and Table 5 respectively; *P < .05
