Mutations that affect ion channels change the sensitivity of Drosophila melanogaster to volatile anesthetics.

Abstract excerpt

We have quantitated the response of D. melanogaster to general anesthetics with a device, the inebriometer, that assays the fly's geotactic and postural behavior. When alleles of several loci that encode or regulate subunits of ion channels were compared with control stocks, several ion channel mutants clearly increased the anesthetic sensitivity of Drosophila. The effects were specific in that: a) for several...
