General Information
Term adult antennal lobe projection neuron DA1 lPN ID (Ontology) FBbt:00067363 (Fly Anatomy)
Definition Adult uniglomerular antennal lobe projection neuron from the dorsal hemilineage of the lateral neuroblast (ALl1) whose dendrites mainly innervate antennal lobe glomerulus DA1 (Bates et al., 2020). It innervates the mushroom body calyx and a small area at the anterior edge of the lateral horn (Marin et al., 2002). It is a fruitless aDT-e neuron (Cachero et al., 2010; Ito et al., 2013). There are around eight of these per hemisphere, they fasciculate with the medial antennal lobe tract and they are cholinergic (Bates et al., 2020).[ FlyBase:FBrf0146917 FlyBase:FBrf0174482 FlyBase:FBrf0211926 FlyBase:FBrf0221438 FlyBase:FBrf0246460 ]
Also Known As "DA1 lPN" ; "DA1_lPN" ; "iACT (DA1)" (for all, see Synonyms field below)
Comment This is a subtype of the fruitless aDT-e neuron, whose lineage is ALl1 (lPN) according to Ito et al. (2013) and is stated to include DA1 PNs in Cachero et al. (2010), but consists of approximately 29 neurons.
