Motor columns caged by crest.
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.
