title: Motor columns caged by crest.
abstract: During development, when barriers between the central and peripheral nervous systems are less tight than at adult stages, it is important that each retains its integrity. A recent article provides evidence that complex mechanisms prevent cellular mixing during this period and reveals an unexpected ability of postmitotic neurons to migrate along their own axons.
