Cerebral blood flow is essential for normal brain function and often perturbed in neurological disease. If one shines a ...

How do blood vessels stay strong, flexible, and responsive to the body's changing need for oxygen and nutrients? The answer lies not only in biology—but also in physics. Researchers at Åbo Akademi ...

New noninvasive tools reveal that subtle shifts in brain blood flow and oxygen use may mirror key markers of Alzheimer’s risk ...

Scientists at MIMETAS have published a new study describing a scalable, self-assembling human blood-brain barrier (BBB) model that combines physiological relevance with high-throughput capability. The ...

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 ...

A wearable ultrasound patch could soon be saving lives, by monitoring the blood flow in hospital patients' brains. The device is only about the size of a postage stamp plus it works continuously, ...

Researchers developed a wearable device that can be used for non-invasive stroke risk assessment. The device uses speckle contrast optical spectroscopy to track changes in blood flow and volume in the ...

A popular hypothesis for how the brain clears molecular waste, which may help explain why sleep feels refreshing, is a subject of debate. Encased in the skull, perched atop the spine, the brain has a ...

Lab-grown organs are a long-time 'holy grail' of organ engineering that has yet to be achieved, but new research has brought that goal a big step closer to reality using a new 3D-printing method ...
