Functions of the Sensory Circumventricular Organs

2003
The morphology, neural connectivity, neurochemistry and modified barrier properties of the sensory CVOs dealt with in the preceding sections are guideposts to the functions that these regions of the CNS subserve. Investigations over the past 30 years have greatly enriched our understanding of why these CVOs are built the way they are and what their ...

Anatomical, molecular and pathological consideration of the circumventricular organs

Neurochirurgie, 2015
Circumventricular organs (CVOs) are a diverse group of specialised structures characterized by peculiar vascular and position around the third and fourth ventricles of the brain. In humans, these organs are present during the fetal period and some become vestigial after birth.

Circumventricular Organs and Cardiovascular Homeostasis

1992
Since the first anatomical description of the circumventricular organs (CVOs) as a structurally distinct group of regions in the central nervous system (CNS), a rapidly emerging body of evidence has implicated the CVOs as physiologically significant autonomic control centers located at the blood-brain interface. Specialized features of these structures

Neurogenesis in the circumventricular organs of adult mouse brains

Journal of Neuroscience Research, 2013
The circumventricular organs (CVOs), including the organum vasculosum of the lamina terminalis (OVLT), subfornical organ (SFO), median eminence (ME), and area postrema (AP), allow parenchyma cells to sense a variety of blood‐derived substances and/or secreted peptides into blood circulation.

The arcuate nucleus as a circumventricular organ in the mouse

Neuroscience Letters, 2011
The present study searched for morphological correlates of the permeability of the ventromedial arcuate nucleus of the mouse to blood-borne proteins. First, we determined that highly permeable microvessels are detected in the ventromedial arcuate nucleus using a rat monoclonal antibody to a mouse-specific endothelial phenotype (clone MECA32) recently ...

The Circumventricular Organs and the Central Actions of Angiotensin

Neuroendocrinology, 2008
This review discusses the central nervous system actions of the circulating hormone, angiotensin II. Access of this peptide likely is limited to thoses central structures which lack the blood-brain barrier. Three of the circumventricular organs, the area postrema, the subfornical organ, and the organum vasculosum, have all been suggested to be sites of

Releasing Factors in the Circumventricular Organs of the Rat Rrain

Endocrinology, 1976
With a recently developed microdissection technique, four circumventricular organs were removed from the rat brain, and their contents of LHRH and TRH were measured. The subfornical organ, the organon vasculosum lamia terminalis, the subcommissural organ, the area postrema all contained significant quantities of both releasing factors.

Sensory circumventricular organs and brain homeostatic pathways

The FASEB Journal, 1993
Circumventricular organs (CVOs), small structures bordering the ventricular spaces in the midline of the brain, have common morphological and endocrine‐like characteristics that distinguish them from the rest of the nervous system.

The microcirculation of rat circumventricular organs and pituitary gland

Brain Research Bulletin, 1987
Blood volume, blood flow, and blood-to-tissue transfer of an amino acid in circumventricular organs, such as the median eminence and subfornical organ, and the pituitary gland of conscious rats were measured by using quantitative autoradiographic techniques and computer-assisted processing of the tissue images.
