The visual circuit from an adult aspt25/Df mutant fly. 3D representation of the lamina (green), medulla (blue), lobula (yellow) and lobula plate (red). Note extreme disorganization between the medulla, lobula and lobula plate, severely reduced lamina structures and complete absence of the ocelli. Stain: 0.5% PTA; slow scan at an image pixel size of 1.2 μm.
