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 coupling of resting-state cerebral blood flow and functional connectivity in Meige syndrome
Frontiers in Neuroscience, 2023 IntroductionMeige syndrome (MS) is an adult-onset segmental dystonia disease, mainly manifested as blepharospasm and involuntary movement caused by dystonic dysfunction of the oromandibular muscles.

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.

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.

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 ...

Toward three-dimensional in vitro models to study neurovascular unit functions in health and disease
Neural Regeneration Research, 2021 The high metabolic demands of the brain require an efficient vascular system to be coupled with neural activity to supply adequate nutrients and oxygen. This supply is coordinated by the action of neurons, glial and vascular cells, known collectively as ...

The role of nitrite in neurovascular coupling [PDF]
Brain Research, 2011 Nitric oxide (NO), a potent vasodilator and nontraditional neurotransmitter, is an important mediator of the changes in cerebral blood flow (CBF) associated with increased neuronal activity (neurovascular coupling). In the present work, we investigated the role of NO and of its newly recognized precursor, nitrite, in neurovascular coupling using a well-

Mechanisms of neurovascular coupling
Regional blood circulation and microcirculation, 2023 The brain is characterized by a well-developed vascular network and consumes a significant proportion of cardiac output relative to its mass. Normally, the metabolic needs of the brain significantly depend on the intensity of the functioning of its various departments, which requires constant regulation of the level of local blood flow.

Revisiting the role of neurons in neurovascular coupling [PDF]
Frontiers in Neuroenergetics, 2010 In this article, we will review molecular, anatomical, physiological and pharmacological data in an attempt to better understand how excitatory and inhibitory neurons recruited by distinct afferent inputs to the cerebral cortex contribute to the coupled hemodynamic response, and how astrocytes can act as intermediaries to these neuronal populations. We
