Legend

Thin section of the optic lobe of a pupal Drosophila brain. Axons of photoreceptors (blue) and lamina neurons (green) bypass the lamina and project into different layers of the medulla (red, center), where the visual information is integrated and processed and further relayed to the lobula complex (red, bottom).
