General Information
Term gustatory receptor neuron C2 of the terminal organ distal group ID (Ontology) FBbt:00047456 (Fly Anatomy)
Definition Larval gustatory receptor neuron of the terminal organ distal group. It has a cell body in the terminal organ ganglion and innervates campaniform sensillum P1 of the terminal organ distal group (Rist and Thum, 2017). There is one of these cells per hemisphere and it expresses at least 7 different gustatory receptors (Kwon et al., 2011). The C2 neuron responds to changes in salt concentration, some amino acids and sucrose (van Giesen et al., 2016).[ FlyBase:FBrf0216529 FlyBase:FBrf0230951 FlyBase:FBrf0236934 ]
