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

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

An angiogram is a diagnostic test that uses X-rays and a contrast dye to visualize the blood vessels in the body, including those in the brain. This test can help diagnose a brain aneurysm. An ...

Add Yahoo as a preferred source to see more of our stories on Google. Brain image Reduced blood flow to the brain is thought to be a key factor in many forms of dementia, including Alzheimer's, and ...

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 ...

Enhancing prefrontal cortex (PFC) cognitive functions requires identifying suitable exercises that increase cerebral blood flow. A recent study using functional near-infrared spectroscopy found that ...

Intensive blood pressure control to a target of less than 120 mm Hg was not associated with a reduction of cerebral perfusion compared with a standard target of less than 140 mm Hg in a substudy of ...

If CBF ceases to function properly, cognitive functions decline. “Cerebral blood flow (CBF) is an important factor that maintains brain function, and a prolonged insufficiency causes degeneration and ...

Cognitive functions, also known as intellectual functions, encompass thinking, understanding, memory, language, computation, and judgment, and are performed in the cerebrum. The prefrontal cortex (PFC ...

Light speckle fluctuations, a noninvasive proxy for cerebral blood flow index (CBFi), are quantified by diffuse correlation spectroscopy. However, this conventional technique provides marginal brain ...
