General Information
Term olfactory receptor neuron of dorsal organ ID (Ontology) FBbt:00007190 (Fly Anatomy)
Definition Odorant receptor expressing bipolar neuron whose dendrite innervates the central dome sensillum of the larval dorsal organ, whose cell body is part of the dorsal organ ganglion and whose axon is carried by the antennal nerve to innervate a larval antennal lobe glomerulus. There are 21 neurons of this type. They receive input from and send output to local neurons in the antennal lobe (Berck et al., 2016).[ FlyBase:FBrf0147119 FlyBase:FBrf0187327 FlyBase:FBrf0232785 ]
Also Known As "DO ORN" ; "DO OSN" ; "odorant receptor neuron of dorsal organ"
