has sensory dendrite in knob sensillum K2 gustatory receptor neuron C6 of the terminal organ distal group larval terminal organ CM1 neuron DoOR:Gr21a.Gr63a Larval gustatory receptor neuron of the terminal organ distal group. It has a cell body in the terminal organ ganglion and innervates knob sensillum K2 of the terminal organ distal group with a dendrite that is folded and densely packed at the distal end (Rist and Thum, 2017). There is one of these cells per hemisphere and it expresses Gr21a and Gr63a (Kwon et al., 2011). The C6 neuron responds to high salt concentrations, hydrochloric, some sugars (van Giesen et al., 2016), carbon dioxide and mechanical stimuli (Komarov et al., 2025). larval terminal organ central-medial 1 neuron VFB:FBbt_00047460 fly_anatomy.ontology FBbt:00047460 mechanosensory neuron of terminal organ distal group mechanosensory eo neuron sugar-sensing neuron salt-sensing neuron sour-sensing neuron high salt/bitter-sensing neuron carbon dioxide sensitive neuron gustatory receptor neuron of terminal organ distal group
