Bleeding occurs when trauma damages a blood vessel. When that trauma involves your head—whether the scalp, skull, or brain—it’s considered a head injury. These head injuries range in severity from a ...

Near-infrared spectroscopy, or fNIRS, offers a way to monitor brain activity without surgery or radiation by tracking changes in blood flow and oxygenation. Light sources placed on the scalp send near ...

Researchers have developed a laser-based device that can measure blood flow noninvasively and differentiate stroke risk based on current physiological conditions. When physicians want to know more ...

The electro-osmotically modulated hemodynamic across an artery with multiple stenosis is mathematically evaluated. The non-Newtonian behaviour of blood flow is tackled by utilizing Casson fluid model ...
