Hypothalamic and extrahypothalamic axonal projects of MBH GHSR neurons: A–H. Representative coronal sections of the brain show mCherry immunoreactivity, a marker of the axonal projections from the MBH GHSR neurons in the Ghsr-IRES-Cre mice injected with hM4Di virus. BSTMA – Bed nucleus of stria terminalis, medial division, anterior; BSTLV – Bed nucleus of stria terminalis, lateral division, ventral, BSTMV – Bed nucleus of stria terminalis, medial division, ventral; LPAG – lateral periaqueductal gray; DLPAG – Dorsolateral periaqueductal gray; VLPAG – Ventrolateral periaqueductal gray. Scale bar in panel H = 200 μm (applies to all panels). Approximate distance of the coronal section from bregma (B) is indicated in each photomicrograph.
