General Information
Term sugar-sensing neuron of the leg ID (Ontology) FBbt:00048210 (Fly Anatomy)
Definition Sensory neuron that responds to sugars and innervates a taste bristle in the leg. These are characterized by expression of gustatory receptors Gr61a and Gr64f, with varying combinations of other Gr64 genes, Gr5a and Gr43a (Ling et al., 2014).[ FlyBase:FBrf0225125 ]
Comment Gr expression determined by an exhaustive Gr-GAL4 expression screen of all Gr genes (although Gr68a expression could not be reliably mapped) in neurons of all tarsal taste bristles of all legs (Ling et al., 2014).
