part of overlaps innervates adult adult optic lobe ventrolateral protocerebrum adult great commissure FBbt:00007080 VFB:FBbt_00007080 adult commissure of optic foci From Strausfeld pg 93 in Musca Domestica (FBrf0239233, FBrf0239234). Confirmed as present in Drosophila melanogaster by VH & WP. GC fly_anatomy.ontology 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). adult VPC2 adult protocerebrum great commissure adult cerebral ganglion
