Sour Taste Responses in Mice Lacking PKD Channels
Figure 3
Sample recordings of gustatory nerve responses of WT, PKD1L3−/−, PKD2L1−/−, and PKD1L3/2L1dbl−/− mice.
A. CT nerve responses. B. GL nerve responses. Taste stimuli were NH4Cl (100 mM), HCl (10 mM), citric acid (10 mM), acetic acid (30 mM), sucrose (500 mM), NaCl (100 mM), quinine (10 mM), MSG (100 mM). Bars indicate taste stimulation (30 sec for CT nerve responses; 60 sec for GL nerve responses).
