In order to function properly, the brain requires a steady flow of blood through the cerebral arteries and veins, which deliver oxygen and nutrients and also remove metabolic byproducts. Therefore, ...

(Nanowerk News) In order to function properly, the brain requires a steady flow of blood through the cerebral arteries and veins, which deliver oxygen and nutrients and also remove metabolic ...

Optical monitoring of cerebral blood flow is a potentially life-saving technology in clinical emergencies, and a number of spectroscopic techniques have been applied to the task. Near-IR spectroscopy ...

Measuring blood flow in the brain is critical for understanding response to a range of neurological problems, including stroke, traumatic brain injury (TBI) and vascular dementia. Obtaining such ...

Arterial spin labeling (ASL) is a non‐invasive magnetic resonance imaging technique that exploits magnetically labelled arterial blood water as an endogenous tracer to quantitatively assess cerebral ...

With $5.1 million in funding, the STAT earpiece measures blood flow to head 24/7 to better understand symptoms that occur upon standing, such as dizziness, brain fog, headaches, fainting, and fatigue ...

Scientists develop an optical technique that can image dynamic changes in the cerebral blood flow to diagnose brain health. Cerebral blood flow (CBF), which supplies oxygen and nutrients to our brain, ...

Diffuse correlation spectroscopy (DCS) is used for noninvasive detection of blood flow. However, current DCS devices need to be improved to increase the signal-to-noise ratio for more accurate ...
