Prominent expression of HSD2 mRNA in a group of cells within the caudal nucleus of the solitary tract (NTS). A and B: autoradiographic in situ hybridization signal for HSD2 mRNA (antisense probe) with dark- and brightfield optics, respectively. C: lack of hybridization signal (sense probe used as a control). [Reproduced with permission from Roland et al. (150).]
