Figure 5.

Mean preference ratios for NaCl (with and without 10 μm amiloride) from 48 hr two-bottle preference tests (tastant vs water; a, b) and whole-nerve recordings from CT (c, d) and NG (e, f) taste nerves stimulated by lingual application of NaCl. For behavioral tests, each genotype group included 9-12 animals. For nerve recordings, each genotype group included six to nine animals. Error bars are SEM. No difference was found between the responses of mice from the four genotypes (behavioral tests) or between those of WT controls and double KOs (nerve recordings).
