Characteristics of the water response across the dorsal epithelium of frog tongue.
1. Dorsal epithelium of the frog tongue produced a change in potential difference across the tissue in response to removal of NaCl from the adapting Ringer solution on the mucosa. 2. The response was not caused by an osmotic decrease in the stimulus, and its profile was in many respects similar to that of the receptor potential in frog taste cells. 3. In conclusion, the response may influence or modify water reception in frogs.
