Abstract
The response of the salt receptor of the blowfly increased with increasing ambient temperature. At constant ambient temperature, the response increased as the relative humidity was raised. At low relative humidity, the temperature of the stimulating solution near its air interface was markedly below ambient temperature, due to evaporation. Warming and cooling the tip of the sensillum while recording from its side respectively raised and lowered the frequency of "spontaneous" action potentials of the receptor. The results indicate that the response of the salt receptor is dependent on the temperature of the stimulus. The Q10 is probably several times greater than one.
