AVP and its receptors in PVN and SON. a AVP was expressed in numerous neuronal soma within PVN. b Neurons within SON showed intense expression of AVP. Arrow points at the intense immunoreactivity in SON. In addition, fibers expressing AVP were spreading within AH. c Positive V1bR neurons were found in SON (arrow) and in AH. However, AVP immunoreactivity was more apparent than V1bR
