antennal lobe glomerulus VP2 [FBbt_00003928]

antennal lobe glomerulus VP2

ID: FBbt_00003928

Ventro-posterior glomerulus of the adult antennal lobe. It lies just medial to glomerulus VP1.

Discernible 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.
