immunohistochemical and horseradish peroxidase ( hrp ) studies suggest that oxytocin-stained fibers from the paraventricular nucleus of the hypothalamus ( pvh ) innervate the locus coeruleus ( lc ) and dorsal vagal complex ( dvc ) in the brainstem of the rat , and that adrenergic fibers from the lc and dvc in turn project to the pvh .
