Electrical properties of salt induced response across the tongue epithelium in frogs.
Transepithelial response across frog tongue epithelium induced by NaCl was compared with that induced by other salts and saccharides. All responses to salts including NaCl were negative in the mucosa to the grounded serosa and were associated with decreased tissue resistance, whereas those to saccharides were positive with increased tissue resistance. The response to salts varied in pattern and magnitude with variation in stimulus quality. The results indicate that the salt induced response is mediated by cation movement through the tissue and is implicated in taste reception.
