Drosophila Chemoreceptors: A Molecular Interface Between the Chemical World and the Brain

Odorant receptors (Ors) have been found to activate an increasing number of behavioral circuits. Gustatory receptors (Grs) are expressed in a wide diversity of organs. Emerging results reveal roles in an expanding repertoire of functions, extending beyond chemoreception. Ionotropic receptors (IRs) are expressed not only in olfactory organs but also in taste organs. A large clade has recently been found to be expressed in all taste organs of the...
