The vascular organ of lamina terminalis (VOLT), organum vasculosum of the lamina terminalis (OVLT), or supraoptic crest[1] is a sensory organ, one of the circumventricular organs of the third ventricle within the lamina terminalis. It is covered with pia mater, and lined with ependyma.[2][3] It overlies the paraventricular nucleus of hypothalamus,[4] and is involved in the secretion of vasopressin.[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 three sensory circumventricular organs of the brain.[5] The other four are secretory.[6]
