NEUROSCIENCE:
Genes Keep Neurons' House in Order

Gretchen Vogel

Scientists have spent decades teasing apart the complex signals that guide axons--the long extensions that allow neurons to communicate with distant cells--to their correct destinations and help them make the right connections. Now on page 686, neuroscientists describe a new family of proteins that help keep the wiring of the roundworm's nervous system tangle free. The discovery indicates the existence of a separate, later-acting maintenance mechanism.
