Mechanisms Underlying Neurovascular Interactions: Blood-Brain Barrier and Neurovascular Coupling
, 2020 To continuously compute neural activity for perception, motor movements and cognition, the central nervous system (CNS) requires a homeostatic microenvironment that is not only enriched in nutrients to meet its high metabolic demands but also devoid of ...

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 ...

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.

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.

Investigating the Limits of Neurovascular Coupling [PDF]
Neuron, 2016 O'Herron et al. (2016) perform two-photon imaging of vascular and neural responses in cat and rodent primary visual cortex to investigate the limits of neurovascular coupling. Their results suggest important constraints on making inferences about neuronal responses from hemodynamic activity.

NEUROVASCULAR COUPLING DURING AGEING AND INMIGRANEURS [PDF]
Zdravniški Vestnik, 2008 A noninvasive assessment of neurovascular coupling using visually evoked cerebral bloodflow velocity responses (VEFR) and visual evoked potentials (VEP), during normal ageingand in migraneurs, would be of great importance for interpretation of functional

Neurovascular coupling in the mammalian brain [PDF]
Experimental Physiology, 2007 Normal brain function requires proper supply of oxygen and glucose in a timely and local manner. This is achieved through an orchestrated intercellular communication between neurones, astrocytes and microvessels that results in a rapid and restricted increase in cerebral blood flow, a process known as neurovascular coupling.

Acute resveratrol consumption improves neurovascular coupling capacity in adults with type 2 diabetes mellitus [PDF]
, 2016 Published: 12 July 2016Background: Poor cerebral perfusion may contribute to cognitive impairment in type 2 diabetes mellitus (T2DM). We conducted a randomized controlled trial to test the hypothesis that resveratrol can enhance cerebral vasodilator ...

Potassium Channels and Neurovascular Coupling
Circulation Journal, 2010 Neuronal activity is communicated to the cerebral vasculature so that adequate perfusion of brain tissue is maintained at all levels of neuronal metabolism. An increase in neuronal activity is accompanied by vasodilation and an increase in local cerebral blood flow.
