Effect of NGCC on the CT responses in rinse solution. A: representative CT trace obtained while the rat tongue was stimulated with R and then with MSG+Bz+SB solutions containing 60 μM or 100 μM NGCC maintained at room temperature. Arrows show time period when the tongue was superfused with R, R+NGCC, MSG+Bz+SB, or MSG+Bz+SB+NGCC. B: mean normalized tonic CT responses to 300 mM NaCl, 100 mM KCl, 100 mM CaCl₂, 500 mM sucrose, 20 mM quinine, and 20 mM HCl in the absence and presence of 2.5 and 50 μM NGCC in 3 rats. *P = 0.0184, **P = 0.0002 (unpaired; n = 3).
