DL4_adPN [FBbt_00100382]

Adult uniglomerular antennal lobe projection neuron of the ad neuroblast (ALad1) lineage with dendrites that mainly innervate antennal lobe glomerulus DL4. It is born during the 20th (and final) division of neuroblast ALad1 during embryogenesis (Yu et al., 2010). It innervates the posteriomedial region of the lateral horn and the mushroom body calyx. There is one of these per hemisphere, it fasciculates with the medial antennal lobe tract and it is cholinergic (Bates et al., 2020).

Adult Cholinergic Olfactory system lineage ALad1 BAmv3 primary neuron

For image, see FBrf0211729. According to Yu et al. (2010), DL6 adPN from Marin et al. (2005) - FBrf0183938 innervates DL4 (this was also the latest-born primary adPN found in the study).
