General Information
Term sugar-sensing neuron of taste bristle ID (Ontology) FBbt:00100041 (Fly Anatomy)
Definition A sugar-sensing neuron that innervates a taste bristle (Montell, 2009). These neurons may also respond to amino acids (Dunipace et al., 2001; Ganguly et al., 2017).[ FlyBase:FBrf0137203 FlyBase:FBrf0179508 FlyBase:FBrf0208984 ]
Comment The projection of S cells (sugar-sensitive) of the labellum to the subesophageal zone, and of leg gustatory sensilla to the thoracic ganglion are segregated from the projections of L2 GRNs (bitter-sensitive) to the central brain (Wang et al., 2004).
