General Information
Term adult great commissure ID (Ontology) FBbt:00007080 (Fly Anatomy)
Definition Commissure of the adult brain located ventral to the fan-shaped body and posterior to the noduli (Ito et al., 2014). It connects the left and right ventrolateral protocerebra, and its main component connects the lobula of both optic lobes (Ito et al., 2014). The commissure also contains many other fibers that connect different neuropils (Ito et al., 2014). It demarcates the boundaries of the posterior ventrolateral protocerebrum (posterior region), posterior lateral protocerebrum (anterior region), noduli (posterior region), inferior bridge (anterior region), superior posterior slope (anterior region), vest (posterior-superior region), epaulette (posterior region) and gorget (inferior region) (Ito et al., 2014).[ FlyBase:FBrf0224194 FlyBase:FBrf0239233 FlyBase:FBrf0239234 ]
Also Known As "adult commissure of optic foci" ; "adult VPC2" ; "GC"
Comment From Strausfeld pg 93 in Musca Domestica (FBrf0239233, FBrf0239234). Confirmed as present in Drosophila melanogaster by VH & WP.
