Nmb cells in rostral parafacial region and dorsal pons are not catecholaminergic. Nmb cells in rostral parafacial region and dorsal pons are not catecholaminergic. A, Transcripts for Pnmt (green) and Nmb (magenta) in dorsal medial medulla at level of C2/C3 adrenergic cell groups. B, Transcripts for Th (green) and Nmb (magenta) in more rostral pontine brain regions. LC, locus coeruleus. C, Enlargement of the white box (rostral RTN) in A. Scale bars: A, 100 μm; B, 500 μm; C, 50 μm. Yingtang Shi et al. J. Neurosci. 2017;37:11744-11757 ©2017 by Society for Neuroscience
