Figure 1: Energy supply, usage and blood flow regulation in the brain. In this Review, we focus on the control of cerebral blood flow by local neuronal activity. We pay less attention to ...

The electrical signaling unit formed by cardiomyocytes and coupled cECs permits a rapid, extremely local response to changes in cardiomyocyte [ATP] i concentrations. This signaling unit could trigger ...

Special vascular cells adjust blood flow in brain capillaries based on local energy needs Date: January 25, 2023 Source: University of Maryland School of Medicine Summary: Researchers have ...

Researchers have discovered a group of cells in the brain that may function as a 'master-controller' for the cardiovascular system, orchestrating the control of blood flow to different parts of ...

"We found that brain cells broadcast their message to many different targets to co-ordinate global control of blood flow," said Associate Professor McMullan.

Blood flow per volume of cytoplasm must be several-fold higher than in resting skeletal muscle, emphasising again the close relationship between perfusion and metabolic function in adipose tissue.

In the brain, if a certain neuron needs more nutrients, it will release signalling molecules that will cause the tiny muscles around a nearby blood vessel to relax. This widens (dilates) the vessel, ...

A stroke, sometimes called a "brain attack," occurs when blood flow to an area in the brain is cut off. If a stroke is not caught early, permanent brain damage or death can result.

Marijuana has a long-term effect on blood flow to the brain, potentially increasing the risk of memory damage and stroke, research finds. The National Institute on Drug Abuse in Baltimore found users ...

An international team of researchers has discovered a group of cells in the brain that may function as a 'master-controller' for the cardiovascular system, orchestrating the control of blood flow ...

These rhythms included the heart and respiration rates, related to the transport of nutrients and oxygen, as well as slower rhythms associated with local control of blood flow. Brain activity ...

L-arginine, an amino acid classified as a dietary supplement, is the biochemical precursor of nitric oxide, which controls local blood flow by relaxing endothelial smooth muscle. In diabetes, L ...
