abstract：:In addition to its traditional role as a circulating vasoactive peptide, vasopressin (VP) has been shown to play significant roles in central cardiovascular processing. The recent description of VP receptors within the subfornical organ (SFO) has suggested this circumventricular organ (CVO) as a potential locus for fe...
