Removal of NA+ and/or Ca2+ from a normal interstitial fluid results in a remarkable decrease of receptor potential amplitudes in a taste cell for salt stimuli. This suggests that the salt-induced receptor potential is strongly related to an increase in the permeability of the taste cell membrane to Na+ and Ca2+.
