| Term | lateral antennal lobe tract projection neuron 4 | ID (Ontology) | FBbt:00047724 (Fly Anatomy) |
| Definition | Adult unilateral multiglomerular antennal lobe (AL) projection neuron, with both glomerular and non-glomerular arborizations within the AL (Tanaka et al., 2012). Its cell body is found on the ventrolateral side of the AL, near the entry point of the antennal nerve, but it is distinct from the lvPNs (Tanaka et al., 2012; Bates et al., 2020). It receives input in the VA1d and VA1v glomeruli and responds to palmitoleic acid (Tanaka et al., 2021). It fasciculates with the lALT and terminates in the dorsomedial part of the posterior ventrolateral protocerebrum, but does not overlap with the optic lobe glomeruli (Tanaka et al., 2012). It also projects to the antennal mechanosensory and motor center and the gnathal ganglion, but not to the lateral horn (Tanaka et al., 2012). There is usually one of these cells per hemisphere (Tanaka et al., 2012; Bates et al., 2020). It is a sexually dimorphic fruitless neuron, with the male cell having a greater number of branches in the protocerebrum and additionally innervating the DA1 glomerulus (Tanaka et al., 2021).[ FlyBase:FBrf0219809 FlyBase:FBrf0246460 FlyBase:FBrf0251877 ] | ||

| Comment | Mapping to MZ_lv2PN based on body ID in Bates et al. (2020) supplement and NeuPrint 1.2.1 notes. Horne et al. (2018) - FBrf0240823 find 3 lPN4 cells in their female VA1v EM reconstruction, but other data suggest just one. | ||
