Push-and-Pull Signals Direct Neuron Migration in the Developing Brain

Scientists have uncovered how developing neurons migrate from the germinal zone, a process critical for proper brain circuit formation. They identified a "push-pull" system where the guidance molecule Netrin-1 repels differentiated neurons, while the ubiquitin ligase Siah2 prevents premature migration by degrading essential proteins.
