Photoreceptor Axons of the Developing Drosophila Visual System

Caption

During the pupal stage, photoreceptors extend the axons into the brain region called medulla which has layered structure. All the photoreceptor axons are labeled in red, and R7 photoreceptor axons are specifically labeled in green. Optic lobes in the brain are labeled in blue. At this stage (24 hours after puparium formation), the R7 axon terminals reaching the single specific layer can be observed (green).
