VL2a_adPN [FBbt_00100380]

Adult uniglomerular antennal lobe projection neuron from the ad neuroblast lineage with dendrites that mainly innervate antennal lobe glomerulus VL2a. It is born from the tenth division of neuroblast ALad1 during embryogenesis (Yu et al., 2010). It innervates the antero-ventral lateral horn (Grosjean et al., 2011). Its terminals in this region overlap extensively with the terminals of DA1 and VA1lm projection neurons, which have been implicated in a pheromone-sensing pathway (Jefferis et al., 2007). There is one of these per hemisphere, it fasciculates with the medial antennal lobe tract and it is cholinergic (Bates et al., 2020).
