General Information
Term sugar-sensing neuron of labellar taste bristle ID (Ontology) FBbt:00058156 (Fly Anatomy)
Definition A sugar-sensing neuron that innervates a taste bristle of the labellum (Montell, 2009). There is one such neuron in each sensillum of the labellum and they all express Gr5a and Gr64f (Weiss et al., 2011).[ FlyBase:FBrf0208984 FlyBase:FBrf0212834 FlyBase:FBrf0240353 ]
