Neurovascular coupling is brain region-dependent

NeuroImage, 2012
Despite recent advances in alternative brain imaging technologies, functional magnetic resonance imaging (fMRI) remains the workhorse for both medical diagnosis and primary research.

Neurovascular coupling in eye-open-eye-close task and resting state: Spectral correspondence between concurrent EEG and fMRI

NeuroImage
Neurovascular coupling serves as an essential neurophysiological mechanism in functional neuroimaging, which is generally presumed to be robust and invariant across different physiological states, encompassing both task engagement and resting state ...

Brain capillary pericytes and neurovascular coupling

Comparative Biochemistry and Physiology Part A: Molecular & Integrative Physiology, 2021
The neurovascular coupling ensures that cerebral activity is matched by the relevant blood flow. The control of the blood flow is mediated by capillaries and by the precapillary aterioles.

Lower neurovascular coupling response despite higher cerebral blood flow at rest in apolipoprotein ɛ4 positive adults.

PLoS ONE
Cerebral blood flow at rest declines with age. However, age-related changes in functional measures of cerebrovascular health including cerebrovascular reactivity and neurovascular coupling are not well understood.

Role of Astrocytes in Neurovascular Coupling [PDF]

Neuron, 2011
Neural activity is intimately tied to blood flow in the brain. This coupling is specific enough in space and time that modern imaging methods use local hemodynamics as a measure of brain activity. In this review, we discuss recent evidence indicating that neuronal activity is coupled to local blood flow changes through an intermediary, the astrocyte ...

Exploration on acupuncture regulation pathways based on neurovascular coupling

针刺研究, 2022
On the basis of the consensus that acupuncture can regulate functional activities of nerves and blood vessels, we, in the present paper, discussed the physiological significance of the functional interactions between the two, and put forward a ...

Arousal state transitions occlude sensory-evoked neurovascular coupling in neonatal mice

Communications Biology, 2023
In the adult sensory cortex, increases in neural activity elicited by sensory stimulation usually drive vasodilation mediated by neurovascular coupling.

The Oxygen Paradox of Neurovascular Coupling [PDF]

Journal of Cerebral Blood Flow & Metabolism, 2013
The coupling of cerebral blood flow (CBF) to neuronal activity is well preserved during evolution. Upon changes in the neuronal activity, an incompletely understood coupling mechanism regulates diameter changes of supplying blood vessels, which adjust CBF within seconds.

Altered resting-state neurovascular coupling in patients with pontine infarction

Experimental Gerontology, 2023
The risk for motor and cognitive impairment is increased in patients with chronic pontine infarction (PI). In this study, we attempted to explore the alterations of neurovascular coupling (NVC) in order to understand the neural basis of behavioral ...

Neurovascular coupling in bone regeneration

Experimental & Molecular Medicine, 2022
AbstractThe mammalian skeletal system is densely innervated by both neural and vascular networks. Peripheral nerves in the skeleton include sensory and sympathetic nerves. The crosstalk between skeletal and neural tissues is critical for skeletal development and regeneration.
