Releasing Factors in the Circumventricular Organs of the Rat Rrain
Endocrinology, 1976With 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.

Functions of the Sensory Circumventricular Organs
2003The 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 ...

Sensory circumventricular organs and brain homeostatic pathways
The FASEB Journal, 1993Circumventricular 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, 1987Blood 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.

Circumventricular Organs and Cardiovascular Homeostasis
1992Since 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

The Pineal Body and the Circumventricular Organs
1974Throughout the history of medicine, opinions on the importance and functions of the pineal body have varied more than those related to any other organ of the body. Descartes saw it as the seat of the functions of the soul, imagining that light impulses could be perceived by the pineal body and then transmitted as humoral signals to the musculature ...

Circumventricular organ capillaries.
Progress in brain research, 1992Most circumventricular organs (CVOs) have unusually dense and permeable capillary networks that facilitate secretion of or tissue penetration by circulating substances, unlike other nervous system structures wherein blood-brain barrier (BBB) properties of the capillary endothelium limit solute permeability.
