Abstract: | The distribution of amiloride-sensitive sodium channels (ASSCs) in taste
buds isolated from the oral cavity of hamsters was assessed by patch clamp
recording. In contrast to the case for rats, taste cells from the
fungiform, foliate and vallate papillae and from the soft palate all
contain functional ASSCs. The differential distribution of ASSCs between
the hamster and the rat may be important for understanding the physiology
underlying the differing behavioral responses of these species to sodium
salts.
