The vascular organ of lamina terminalis (VOLT) (also known as organum vasculosum of the lamina terminalis(OVLT), or supraoptic crest[1]) Is a ependymal[2] chemosensory organ[3] of the third ventricle situated beneath the lamina terminalis. It overlies the paraventricular nucleus of hypothalamus.[2] The VOLT monitors the presence of peptides and macromolecules in the bloodstream, and conveys the information to the hypothalamus.[3]
It is one of the four sensory circumventricular organs of the brain (the others being the subfornical organ, the median eminence, and the area postrema).[4]
