These cells do not project deeper than M6, but have vertical projections, extending upwards from M6, following incoming R8 terminals (Sancer et al., 2019). They vary in morphology based on their position (Sancer et al., 2019). Dm-DRA2 DmDRA2 VFB:FBbt_00049484 FBbt:00049484 dorsal rim area optic column
