The change in blood flow that occurred with these slow waves was up to 20% of the entire brain blood supply. Surprisingly, this phenomenon was only weakly tied to changes in brain activity.

They found that the penetrating arterioles, which connect the blood vessels on the brain’s surface with deeper blood vessels, are a vulnerable link in the network.

In the brain, not all blood flow is created equal. RIKEN researchers have developed a detailed cortical layer map of the ...

Instead of just responding to the energy needs of neurons, the blood can have a direct and powerful influence on the brain.

When certain brain areas work hard at something, more blood flows to those regions to help them refuel. Vessels do this by dilating near the spots that need a supply boost.

Wearing a tie that causes slight discomfort can reduce blood flow to the brain by 7.5%, but the reduction is unlikely to cause any physical symptoms, which generally begin at a reduction of 10%.

A Ludwig Cancer Research study has generated a granular portrait of how the cellular and molecular components of the blood vessels that feed brain metastases of melanoma and lung and breast ...

This article will highlight the importance of brain blood flow to health and how Alzheimer’s disease is marked with severe reductions.

Head injuries bleed a lot because of all the blood vessels there. Your brain requires a tremendous amount of oxygen to do its job. In fact, about 20 percent of the blood flowing from your heart goes ...

There's also a loss of pericytes, a type of cell that regulates blood supply and blood vessel permeability, too. As a result, the blood vessels become "leaky," compromising the blood-brain barrier.

STAT's earpiece, a small wearable designed to monitor CBF, in order to better understand how the measurement is related to conditions.

Blood flow makes waves across the surface of the mouse brain Date: May 29, 2024 Source: NIH/National Institute of Neurological Disorders and Stroke Summary: Researchers have, for the first time ...
