Fig 6. The relative responses to 0.1 M NH₄Cl of the chorda tympani nerve to taste solutions.

Mean relative responses of the chorda tympani nerve (+ SEM) to 0.1 M NaCl, 0.1 M MSG, 50 mM saccharin, 0.3 M sucrose, 0.3 mM QHCl, 20 mM QHCl, and 50 mM HCl. The responses to each taste solution did not significantly differ among age groups.
