Electrical response to hypotonic NaCl Ringer solution across the dorsal epithelium of the tongue of the frog, Rana catesbeiana.
Stimulation with hypotonic NaCl Ringer solution produced a change in potential across the epithelium, which was not caused by decreased osmotic pressure. The potential profile resembled the receptor potential of frog taste cells and so may be related to water reception.
