Caltech and the Keck School of Medicine of USC have developed a new laser-based headset device that can noninvasively measure blood flow and volume. Caltech postdoctoral scholar Simon Mahler is shown ...

Laser speckle contrast imaging (LSCI) measures blood flow across wide areas of brain tissue with high precision, providing new evidence of how blood vessels coordinate brain perfusion. Temporal ...

Blood vessels in the brain are highly interconnected and efficient in actively regulating blood flow. Yet, the mechanisms that regulate flow are not well studied on a holistic level. To determine how ...

Researchers have shown how the brain communicates to blood vessels when in need of energy, and how these blood vessels respond by relaxing or constricting to direct blood flow to specific brain ...

Abnormal blood flow in the aorta is linked to inflammation and breakdown of the vessel wall in conditions where the aorta is dilated. This is shown in a study led by researchers at Linköping ...
