Anatomical organization of the rat organum vasculosum laminae terminalis.
The organum vasculosum of the laminae terminalis (OVLT) is a circumventricular organ located along the ventral part of the anterior wall of the third ventricle. Because it lacks a complete blood-brain barrier (BBB), blood-borne signals detected in the OVLT provide the brain with information from the periphery and contribute to the generation of centrally mediated responses to humoral feedback a...
متن کاملFrancis Bacon: an Alchemical Odyssey through the Novum Organum
One of the most fascinating and thought-provoking periods in the history of chemistry is the coexistence in Western Europe of the ancient alchemy (having most likely arisen from Hellenistic and Arabic influences) and the rational, scientific chemistry we know today. By its own nature, this is a rather indeterminate period ranging from the Renaissance (around the 15 and 16 centuries) to early in...
متن کاملHypertonicity sensing in organum vasculosum lamina terminalis neurons: a mechanical process involving TRPV1 but not TRPV4.
Primary osmosensory neurons in the mouse organum vasculosum lamina terminalis (OVLT) transduce hypertonicity via the activation of nonselective cation channels that cause membrane depolarization and increased action potential discharge, and this effect is absent in mice lacking expression of the transient receptor potential vanilloid 1 (Trpv1) gene (Ciura and Bourque, 2006). However other exper...
متن کاملThe organum vasculosum laminae terminalis in immune-to-brain febrigenic signaling: a reappraisal of lesion experiments.
The organum vasculosum laminae terminalis (OVLT) has been proposed to serve as the interface for blood-to-brain febrigenic signaling, because ablation of this structure affects the febrile response. However, lesioning the OVLT causes many "side effects" not fully accounted for in the fever literature. By placing OVLT-lesioned rats on intensive rehydration therapy, we attempted to prevent these ...
متن کاملOrganum Vasculosum of the Lamina Terminalis Detects NaCl to Elevate Sympathetic Nerve Activity and Blood Pressure.
High-salt diet elevates NaCl concentrations in the cerebrospinal fluid to increase sympathetic nerve activity (SNA) in salt-sensitive hypertension. The organum vasculosum of the lamina terminalis (OVLT) resides along the rostral wall of the third ventricle, lacks a complete blood-brain barrier, and plays a pivotal role in body fluid homeostasis. Therefore, the present study used a multifaceted ...
