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 New York University School of Medicine and collaborators found that capillary-associated macrophages in skin decline with ...

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 ...

This is a preview. Log in through your library . Abstract Analysis of the spatiotemporal coupling between neuronal activity and cerebral blood flow requires the precise measurement of the dynamics of ...

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 ...

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 ...

A new ultrasound-based imaging tech has been developed to map the organ blood flow in four dimensions (3D + time) — a level ...

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 ...
