Neurovascular coupling (NVC) is the dynamic regulation of cerebral blood flow in response to neural activity. Specifically, when neurons become active, nearby blood vessels dilate to increase blood ...

It also reduced nitric oxide (NO) production by about 20 percent and increased endothelin-1 (ET-1), a potent vasoconstrictor, by roughly 30 percent—changes that may disrupt cerebral blood flow ...

COSTA MESA, Calif., April 7, 2025 /PRNewswire/ -- A major international study, published this week in JAMA Psychiatry, has identified a powerful new brain-based biomarker for Major Depressive Disorder ...

However, there are concerns that they may increase intracranial pressure. The objective of this systematic review is to assess whether, and if so, to what extent volatile anaesthetic agents affect ...

Cerebral blood delivery depends on mechanisms such as electrical signaling, which propagates through capillary networks to upstream arterioles to deliver blood, and calcium signaling, which fine ...

BACKGROUND: Neurogenic orthostatic hypotension (nOH) causes pathological falls in standing blood pressure that may or may not be symptomatic. nOH also raises the risk of poor neurological outcomes ...

To address many of the deficiencies in optical neuroimaging technologies, such as poor tempo-spatial resolution, low penetration depth, contact-based measurement, and time-consuming image ...

The study investigated the effects of short-duration and light-intensity exercise on increasing cerebral blood flow in children.

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