AN important feature of the peripheral circulation is the close correspondence between the local needs of a given tissue and the amount of blood supplying it. Controlling mechanisms, to accomplish ...

The finest scale of blood flow through the brain occurs in capillaries. Suspicions that capillary flow is regulated by cells that put the squeeze on these vessels are now borne out by detailed ...

New research on tiny capillaries and cells called pericytes details how blood moves through over 400 miles of total vasculature in the human brain. While the human brain has over 400 miles of total ...

New research has uncovered that capillaries have the capacity to both sense brain activity and generate an electrical vasodilatory signal to evoke blood flow and direct nutrients to neurons. All it ...

The study included 34 patients (24 women and 10 men; age, 27–55 years). The mean (SD) duration of RS symptoms prior to the baseline examination was 11 (10) years. The inclusion criterion was the ...

A new method for imaging blood circulation and the flow within blood vessels could lead to faster and more precise assessments of capillary dynamics. In particular it should help the understanding of ...

The brain is perhaps the most sensitive organ with respect to changes in blood flow and oxygen supply. Even brief interruptions in capillary flow (or "stalling") can indicate acute neurological issues ...

New University of Virginia School of Medicine research suggests an unexpected way doctors may be able to improve blood flow to the brain to battle Alzheimer's and other neurodegenerative diseases.

While the human brain has over 400 miles of total vasculature, little is known about the tiny capillaries that make up much of this intricate labyrinth of blood vessels critical for delivering ...
