title: Ion specificity of rat chorda tympani fibers to chemical and electrical tongue stimulations.
abstract: Responses of rat single chorda tympani fibers to ionic chemical stimuli and anodal tongue stimulations with ionic bathing solutions were examined. Fourteen out of 30 fibers showed the highest sensitivities to NaCl for both chemical and electrical stimulations, whereas the remaining 16 fibers showed almost no ion specificity for electrical stimulation even though most of them have the highest sensitivities to HCl for chemical stimulation. Ion specificity for electrical stimulation was significantly smaller than that for chemical stimulation.
