In wild-type animals, the perpendicular γ axonal branches in the larval mushroom body lobes are completely pruned by 18 hours after puparium formation (AFP). γ neurons subsequently re-extend their axons horizontally to form the midline projecting γ lobe in adult brains. This remodeling is blocked by pan-glial expression of myoVDRC.cUa under the control of Scer\GAL4repo.8.5. The perpendicular axonal branches of γ neurons persist through early metamorphosis, and the abnormally retained larval neurites co-exist with the α/β lobes in the adult mushroom bodies that failed to remodel. The brains expressing myoVDRC.cUa via Scer\GAL4repo.8.5 are otherwise grossly normal.
