Organum Vasculosum Of The Lamina Terminalis (Ovlt) Neurons is an important component in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes.
The Organum Vasculosum of the Lamina Terminalis (OVLT) is a circumventricular organ located in the rostral wall of the third ventricle. As one of the median eminence-connected structures, the OVLT lacks a complete blood-brain barrier and serves as the primary sensory interface for circulating molecules involved in body fluid homeostasis, autonomic regulation, and neuroendocrine control. [@ciofi2011]
Overview
The OVLT is situated in the preoptic region, immediately dorsal to the optic chiasm and rostral to the median preoptic nucleus. It is characterized by dense networks of fenestrated capillaries that allow direct contact between circulating blood-borne substances and neural tissue. This makes the OVLT uniquely positioned to monitor systemic signals including: [@ganong2000]
