<i>Bscl2</i> mRNA distribution within the PVN and DVC.

<p>Radioactive in situ hybridisation histochemistry analysis of <i>Bscl2</i> mRNA distribution in coronal section across three rostral-to-caudal levels of adult PVN and DVC. (<b>A–C</b>) ³⁵S-labelled <i>Bscl2</i> mRNA expression in the PVN demonstrating robust labelling in the ventral (A), medial magnocellular (B), lateral magnocellular (B, C) and posterior domains (C). Scattered <i>Bscl2</i> labelled cells were expressed in the anterior and medial (B, C) parvicellular portion. (<b>D–F</b>) ³⁵S-labelled <i>Bslc2</i> mRNA expression in the DVC was highest within the 10N at the level of the area postrema. Within the NTS the preponderance of <i>Bscl2</i> mRNA was localised to the medial and ventral domains (E, F). No expression was detected in the area postrema (E). 4v, fourth ventricle; 10N, dorsal motor nucleus of the vagus; 12N, hypoglossal nucleus; AP, area postrema; cc, central canal; PaAP, PVN anterior parvicellular; PaLM, PVN lateral magnocellular; PaMM, PVN medial magnocellular; PaMP, PVN medial parvicellular; PaPo, PVN posterior; PaV, PVN ventral; SolC, NTS commissural; SolDL, NTS dorsolateral; SolG, NTS gelatinous; SolIM, NTS intermediate; SolM, NTS medial; SolV, NTS ventral; SolVL, NTS ventrolateral.
