General Information
Term antennal lobe glomerulus VP2 ID (Ontology) FBbt:00003928 (Fly Anatomy)
Definition Ventro-posterior glomerulus of the adult antennal lobe. It lies just medial to glomerulus VP1.[ FlyBase:FBrf0051437 FlyBase:FBrf0107836 FlyBase:FBrf0187305 FlyBase:FBrf0210390 FlyBase:FBrf0211729 FlyBase:FBrf0213085 FlyBase:FBrf0219809 FlyBase:FBrf0227110 ]
Also Known As"antennal glomerulus VP2" ; "hot glomerulus" ; "medial PAP" (for all, see Synonyms field below)
CommentDiscernible with Golgi impregnation or CoCl2 backfills (Stocker et al. 1990), but not with nc82/bruchtpilot immunolabelling, leading to it not being represented in antennal lobe maps (Laissue et al., 1999, Couto et al., 2005) or having its position changed (Chou et al., 2010; Yu et al., 2010). According to Chou et al (2010) glomerulus VP2 is located in between glomeruli VP1 and VP3. In Gallio et al (2011), glomerulus VP2 is described as corresponding to the medial region of the proximal antennal protocerebrum (PAP) which is innervated by hot-sensing neurons.
