This confocal image shows the dendritic arborization of a sensory neuron in a Drosophila larva overexpressing the ATPase ATP7, a metal transporter that regulates cytoplasmic copper levels. Overexpression of ATP7 mimics aspects of Menkes disease, reducing dendritic complexity. For more information, see the article by Hartwig et al. (pages 215–233).
