Fig. 1. Characterization of noradrenergic interneuron precursors in the caudal
hindbrain. Hindbrain flat-mount preparations of E11.5 control embryos showing
the mRNA expression of (A) Dbh, (B) Rnx, (C) Phox2b
and (D) Mash1. The box outlines the domain that gives rise to
noradrenergic visceral sensory interneurons of the solitary tract nucleus
(STN). LC, locus ceruleus; FBMN, facial branchiomotoneurons.
