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.

摘要

研究了大鼠单根鼓索神经纤维对离子化学刺激以及用离子浴液进行阳极舌刺激的反应。30根纤维中有14根对化学刺激和电刺激均对氯化钠表现出最高敏感性，而其余16根纤维对电刺激几乎没有离子特异性，尽管它们中的大多数对化学刺激对盐酸表现出最高敏感性。电刺激的离子特异性明显小于化学刺激的离子特异性。
