(A) In situ hybridization of a ³⁵S-labeled antisense Kiss1r cRNA riboprobe in the preoptic area (POA), suprachiasmatic nucleus (SCN), paraventricular nucleus (PVN), lateral habenular nuclei (LHb), paraventricular thalamic nuclei (PVT), ventromedial hypothalamic nucleus (VMH), and arcuate nucleus (ARC) of Syrian hamster brain sections, bar = 2 mm; (B) specific (full line) and non-specific (dotted line) hybridization signal with a ³⁵S-labeled antisense Kiss1r cRNA riboprobe in Syrian hamster lateral habenular nuclei.
