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 ...

WHILE it is obvious that the capillary circulation is subject to local physiological control, there is much difference of opinion as to how this is achieved. In particular, it is still undecided ...

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 ...

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 ...

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 ...

When you sit quietly for a moment listening to your heart pump blood through your body, do you think about blood vessels as a firehose drenching your organs and brain with red blood cells full of ...

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.

All it takes is the flip of a protein "switch" within the tiny wire-like capillaries of the brain to increase the blood flow that ensures optimal brain function. New research has uncovered that ...
