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.

Neurovascular coupling in the healthy and inflamed brain [PDF]

The structural and functional integrity of the brain relies on a close balance between the metabolic demands of neurons and supporting glia, and substrate delivery in the form of blood flow.

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

Neurovascular coupling unit dysfunction and dementia: Retinal measurements as tools to move towards population-based evidence

Frontiers in Endocrinology, 2022
Dysfunction of the neurovascular coupling unit may be an important contributor to dementia. The neurovascular coupling unit comprises neuronal structures (e.g. astrocytes) and vascular structures (e.g.

Comparing dynamic causal models of neurovascular coupling with fMRI and EEG/MEG

NeuroImage, 2020
This technical note presents a dynamic causal modelling (DCM) procedure for evaluating different models of neurovascular coupling in the human brain – using combined electromagnetic (M/EEG) and functional magnetic resonance imaging (fMRI) data.

Neurovascular complications in displaced extension-type supracondylar fractures in children : outcome of conservative management [PDF]

, 2010
Includes bibliographical referencesThe aim of our study was to review our conservative management of neurovascular complications in displaced extension-type supracond ylar fractures of the humerus in children. We critically analysed the outcomes.
