Visual interneurons obtained from the beautiful swallowtail butterfly were injected with the fluorochrome Lucifer yellow in order to capture the image illustrated above. The specimen was imaged with extended focus in 100-micrometer serial sections through the 383-micrometer axial range of the specimen and displayed in an overlapping pseudo coloring scheme. The image was provided by Mituyo Kinoshita and Kentaro Arikawa from the Laboratory of Neuroethology in the Graduate School of Integated Science at the Yokohama City University, in Japan.
