Abstract excerpt
In zebrafish there are two populations of motoneurons, primary and secondary, that are temporally separate in their development. To determine if midline cells play a role in the specification of these neurons, we analyzed both secondary and primary motoneurons in mutants lacking floor plate, notochord, or both floor plate and notochord. Our data show that the specification of secondary motoneurons, those most...
