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.

摘要

从蛙的嗅球记录到其对去离子水的嗅觉反应（水反应）。电解质和非电解质均会根据渗透压抑制水反应，而味觉细胞中的水反应不会被非电解质抑制。由此得出结论，施加去离子水引起的渗透压降低是蛙嗅觉系统中水反应的起源。
