SummaryThe differentiated cytology, cytochemistry, and functions within subdivisions of the tuber cinereum prompted this morphometric and physiological investigation of capillaries in the median eminence and arcuate nucleus of albino rats. Morphometric studies established that the external zone of the median eminence had 3–5 times the number and surface area of true and sinusoidal capillaries than the internal or subependymal median eminence zones, or either of two subdivisions examined in the… 

Astrocytes in the arcuate nucleus and median eminence that take up a fluorescent dye from the circulation express leptin receptors and neuropeptide Y Y1 receptors

Hydroxystilbamidine demonstrates that astrocytes take up molecules from the circulation in the median eminence and adjacent arcuate nucleus, and may have a significant signalling role in regulation of food intake.

Differential uptake of molecules from the circulation and CSF reveals regional and cellular specialisation in CNS detection of homeostatic signals

The uptake of hydroxystilbamidine and wheat germ agglutinin into the hypothalamus, two hours after injections into either the circulation or the cerebrospinal fluid, were compared in adult rats to highlight the regional and cellular specialisation for uptake of molecules from the circulation and CSF.

Brain-endocrine interactions: a microvascular route in the mediobasal hypothalamus.

It is determined that permeable microvessels are part of the subependymal plexus irrigating exclusively the ventromedial ARC from the subadjacent neuroendocrine median eminence, and marked topography strongly supports the functional importance of retrograde blood flow from the pituitary to the vmARC.

Aquaporin-1 in blood vessels of rat circumventricular organs

AQP1-immunoreactive endothelia have also been seen in a small population of blood vessels in the cerebral parenchyma outside the circumventricular organs, similar to other observations in human brain.

Ventromedial arcuate nucleus communicates peripheral metabolic information to the suprachiasmatic nucleus.

It is proposed that the vmARC forms a complex with the seME, their reciprocal connections with viscerosensory areas in brain stem, and other circumventricular organs, suggesting the exchange of metabolic and circulating information.

Comparing the Superficial Vasculature of the Central Nervous System in Six Laboratory Animals: A Hypothesis About the Role of the “Circle of Willis”

Using this approach, the brain vascular system was successfully mapped in six different species of animals and can guide other researchers as they design research studies and create experimental models for new surgical procedures and approaches.

Quantitative differences among capillary networks in four distinct compartments of the rat SFO are revealed and morphometric dimensions for the three types of capillary existing in this cerebral sensory nucleus are provided.

The functional and structural border of the neurohemal region of the median eminence

A border area exists adjacent to the dorsolateral aspect of the neurohemal region of the median eminence where the tanycytes isolate the neuropil from the cerebrospinal fluid not only by their apical Tight junctions, but also by basal tight junctions from the subendothelial cleft.

Cellular organization of the lateral and postinfundibular regions of the median eminence in the rat

The structural organization of the rostral, lateral and postinfundibular regions of the median eminence of 5-day cyclic diestrous rats was studied with light and electron microscopic methods and the ultrastructural characteristics of the β1 tanycytes are described and their ependymal endings tentatively classified into three types.

Capillary density, volume fraction, length, surface area, and diameter were assessed in four regions in the sagittal plane (rostral, “transitional,” central, and caudal) and two zones in the coronal plane (dorsal and ventromedial).
