Neuronal migration is an artwork depicting many very young neurons that have been produced in the neuroepithelium migrating to their appropriate destinations in the brain. This image highlights the future of neuroscience showing different classes of cells colour coded. There is no available technique to do this now, but it is not far off considering the advances that have been made with brainbow mice. The brainbow technique allows for different cell types to be tagged with fluorescent proteins to track their development and connections with other cells.
