Darkfield photomicrographs showing the appearance of PHAL-labeled axons from the BSTdm (experiment BST116) in transverse histological sections through the paraventricular hypothalamic nucleus from rostral to caudal (A-G; about Fig. 4J-O). For subdivisions of the paraventricular nucleus, see the corresponding caudally adjacent thionin-stained transverse sections (A'-G'). Arrows point to the same blood vessels in the pairs of photomicrographs. Scale bars = 150 μm.
