The Organum Vasculosum Laminae Terminalis and Water Balance in Dogs
Circumventricular organs (CVO) are unique regions of the brain which lack the blood-brain barrier. Thus, neurons, or their processes, located within CVO’s are in relatively free communication with blood. This anatomical peculiarity and other evidence which suggests the forebrain contains osmoreceptive elements, have made the subfornical organ (SFO) and the organum vasculosum laminae terminalis (OVLT), prime candidates as receptor areas for the regulation of water balance.
