This image shows tracheal sensory neuron axons from the body and gustatory sensory axons from the head converging on the Subesophageal Zone (SEZ) in a Drosophila third instar larva CNS. A Gr28a-Gal4 line was used to drive fluorescent protein expression in specific sensory neurons for visualization. Immunostaining against Elav was used to visualize neuronal nuclei of the CNS. Sensory axons from terminal cone neurons labelled by the Gal4 line are excluded from this image. Image and art work courtesy of Sam Qian and Luke Hammond. (pages 2081–2093).
