General Information
Term gustatory receptor neuron B2 of the terminal organ dorsolateral group ID (Ontology) FBbt:00047454 (Fly Anatomy)
Definition Larval gustatory receptor neuron of the terminal organ dorsolateral group. This neuron has a cell body in the dorsal organ ganglion and innervates the dorsomedial papilla of the terminal organ (Rist and Thum, 2017). There is one of these cells per hemisphere and it expresses Gr33a, Gr66a, Gr32a and Gr10a (Kwon et al., 2011). The B2 neuron responds to bitter stimuli, including quinine and denatonium (van Giesen et al., 2016).[ FlyBase:FBrf0216529 FlyBase:FBrf0230951 FlyBase:FBrf0236934 ]
