General Information
Term high salt-sensing neuron of labellar taste bristle ID (Ontology) FBbt:00052561 (Fly Anatomy)
Definition Gustatory receptor neuron that innervates a taste bristle of the labellum and responds to high concentrations of cations, including sodium and potassium (Montell, 2021). These neurons can be found innervating short and large sensilla and they express ppk23 (Montell, 2021).[ FlyBase:FBrf0248270 ]
Also Known As"cation-sensing GRN of labellum" ; "cation-sensing gustatory receptor neuron of labellum" ; "labellar taste bristle type D gustatory receptor neuron" (for all, see Synonyms field below)
