Term | adult olfactory receptor neuron Or56a | ID (Ontology) | FBbt:00067063 (Fly Anatomy) |
Definition | Olfactory receptor neuron (ORN) that expresses Or56a and Or33a (Stensmyr et al., 2012). Its dendrite transduces signals from antennal basiconic sensillum ab4 (Stensmyr et al., 2012). Its axon innervates the DA2 glomerulus in the ipsilateral antennal lobe, then crosses the midline via the antennal commissure to innervate the contralateral antennal lobe glomerulus DA2 (Stocker et al., 1990; Stensmyr et al., 2012). It expresses sNPF (Carlsson et al., 2010). There are approximately 24 of these cells on each side in females and 21 in males (Grabe et al., 2016). These neurons detect geosmin (via the Or56a receptor), which indicates the presence of harmful microbes (Stensmyr et al., 2012).[ FlyBase:FBrf0051437 FlyBase:FBrf0179238 FlyBase:FBrf0187305 FlyBase:FBrf0190010 FlyBase:FBrf0211156 FlyBase:FBrf0220150 FlyBase:FBrf0233453 ] | ||
