General Information
Term Gr2a neuron of adult labral sensillum 7 ID (Ontology) FBbt:00048143 (Fly Anatomy)
Definition Chemosensory neuron that has a dendrite in sensillum 7 of the adult labral sense organ and expresses Gustatory receptor 2a, as well as other taste receptors (Chen and Dahanukar, 2017). Its axon terminals are in the subesophageal zone (Kim et al., 2017). It is involved in the aversive response to high salt concentrations (Kim et al., 2017). There is one (bilateral) pair of these neurons (Chen and Dahanukar, 2017).[ FlyBase:FBrf0235764 FlyBase:FBrf0237413 ]
