UC Berkeley scientists have developed a magnetic resonance imaging technique that tracks blood through the brain’s veins back ...

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

Moreover, by visualizing these changes in an intact living brain, the technique allows for the assessment of how potential treatments impact brain blood flow, thus marking a significant ...

Conceptual framework of venous perfusion source mapping in the superior cerebral veins. Credit: Nature Communications (2025). DOI: 10.1038/s41467-025-59108-3 ...

The mean differences between blood flow velocities measured by the ultrasound patch and the conventional TCD probe were −1.51±4.34, −0.84±3.06 and −0.50±2.55 cm/s for peak systolic, mean flow and end ...

Microplastics may cause blockages in blood vessels in the brain and affect behavior, according to a study on mice. U.S. World; ... which could cause prolonged obstructions to blood flow in the brain.

During that time, it continuously monitors and records the blood flow in their brain. The patch incorporates multiple layers of stretchable electronics, including layers of copper electrodes and ...

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.

This discovery highlights the critical role of capillaries in managing blood flow within the brain. By identifying how electrical and calcium signals work together through electro-calcium ...
