obsolete antennal lobe glomerulus VA1 lateral compartment true antennal lobe glomerulus VA1 lateral compartment VA1l fly_anatomy.ontology This term was obsoleted because there is no evidence that the two subcompartments that have been identified as being part of glomerulus VA1v, VA1l and VA1m, are distinct, and so do not appear to be useful. VA1v FBbt:00007099 Large, lateral-most compartment of antennal lobe glomerulus VA1. It lies along the ventral side of the dorsal compartment of glomerulus VA1, and is dorsal to glomerulus VA5 (Laissue et al., 1999). The VA1l compartment, together with the antennal lobe glomerulus VA1 medial compartment (VA1m) is also known as antennal lobe glomerulus VA1 ventral compartment (VA1v) (Laissue and Vosshall, 2008). antennal lobe glomerulus VA1v
