Free ion concentrations in receptor lymph and role of transepithelial voltage in the fly labellar taste receptor

Free ion concentrations in the receptor lymph of the labellar taste hair were examined on the fleshfly Boettcherisca peregrina, making use of several kinds of ion-selective microelectrodes inserted into the outer lumen of the taste hair through its cut end. The receptor lymph was rich in Na+ and Cl- but poor in K+, that is, concentrations of free Na+, K… CONTINUE READING
