title: Water response of frog olfactory system is induced by a decrease in osmotic pressure.
abstract: The frog olfactory response to deionized water (water response) was recorded from the olfactory bulb. The water response was suppressed by both electrolytes and non-electrolytes as a function of osmolarity, while the water response in taste cells was not suppressed by non-electrolytes. It was concluded that a decrease in osmotic pressure induced by application of deionized water is the origin of the water response in the frog olfactory system.
