The visual circuit from an adult GFP::AspMF transgenic rescue fly. 3D representation of the lamina (green), medulla (blue), lobula (yellow) and lobula plate (red) from flies expressing AspMF in the aspt25/Df mutant background. Note complete rescue of morphology defects and the ocelli. Stain: 0.5% PTA; slow scan at an image pixel size of 1.2 μm.
