has sensory dendrite in campaniform sensillum P2 gustatory receptor neuron C1 of the terminal organ distal group VFB:FBbt_00047455 FBbt:00047455 Larval gustatory receptor neuron of the terminal organ distal group. It has a cell body in the terminal organ ganglion and innervates campaniform sensillum P2 of the terminal organ distal group (Rist and Thum, 2017). There is one of these cells per hemisphere and it expresses a wide range of gustatory receptors (at least 17) (Kwon et al., 2011). The C1 neuron has a weak response to caffeine (Choi et al., 2016). fly_anatomy.ontology sensory neuron of campaniform sensillum bitter-sensing neuron gustatory receptor neuron of terminal organ distal group
