FIGURE 3.

Whole-nerve responses to 100 mmol/L KCl, 5 mmol/L citric acid, 0.3 mmol/L (for the GL) and 1 mmol/L (for the CT) QSO₄, 100 mmol/L MPG, 500 mmol/L Glc, 500 mmol/L Suc, 500 mmol/L galactose, 1 mmol/L SC, 10 mmol/L saccharin and 16% polycose in the CT and/or GL of WT 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 2 and Table 3 respectively; *P < .05, ^†P < .01. CT, chorda tympani; GL, glossopharyngeal; WT, wild-type
