General Information
Term antennal lobe glomerulus VP4 ID (Ontology) FBbt:00110865 (Fly Anatomy)
Definition Ventro-posterior glomerulus of the adult antennal lobe. It lies dorsoposterior to glomerulus VP3, ventral to DP1.[ FlyBase:FBrf0215822 FlyBase:FBrf0219809 FlyBase:FBrf0227110 ]
Also Known As "antennal glomerulus VP4" ; "arm glomerulus" ; "dry glomerulus" (for all, see Synonyms field below)
Comment Discernible with Golgi impregnation, but not with nc82/bruchtpilot immunolabelling, according to Tanaka et al. (2012) this glomerulus corresponds to part of the innervation region of IR40a ORNs, identified as the 'arm' by Silbering et al. (2011). Although VP1 and VP4 glomeruli are innervated by IR40a neurons, these correspond to different subsets and are therefore considered different glomeruli (Tanaka et al., 2012).
