Vasculo-Neuronal Coupling and Neurovascular Coupling at the Neurovascular Unit: Impact of Hypertension [PDF]

Frontiers in Physiology, 2020
Components of the neurovascular unit (NVU) establish dynamic crosstalk that regulates cerebral blood flow and maintain brain homeostasis. Here, we describe accumulating evidence for cellular elements of the NVU contributing to critical physiological ...

Neurovascular Coupling: A Parallel Implementation [PDF]

Frontiers in Computational Neuroscience, 2015
A numerical model of neurovascular coupling (NVC) is presented based on neuronal activity coupled to vasodilation/contraction models via the astrocytic mediated perivascular K + and the smooth muscle cell (SMC) Ca2+ pathway termed a neurovascular unit ...

Retinal Neurovascular Coupling: From Mechanisms to a Diagnostic Window into Brain Disorders [PDF]

Cells
Retinal neurovascular coupling reflects the precise coordination between neuronal activity, glial support, and vascular responses, mirroring key neurovascular mechanisms in the brain. This review emphasizes the cellular and molecular processes underlying

Disturbed neurovascular coupling in hemodialysis patients [PDF]

PeerJ, 2020
Background Altered cerebral blood flow (CBF) and amplitude of low-frequency fluctuation (ALFF) have been reported in hemodialysis patients. However, neurovascular coupling impairments, which provide a novel insight into the human brain, have not been ...

Measurement of Neurovascular Coupling in Neonates [PDF]

Frontiers in Physiology, 2019
Neurovascular coupling refers to the mechanism that links the transient neural activity to the subsequent change in cerebral blood flow, which is regulated by both chemical signals and mechanical effects.

Neurovascular coupling, cognition, and cardiac function in stroke-free atrial fibrillation [PDF]

NeuroImage: Clinical
Objectives: Atrial fibrillation (AF) is linked to cognitive impairment even without overt stroke, potentially via neurovascular coupling (NVC) dysfunction.

Neurovascular coupling during deep brain stimulation [PDF]

Brain Stimulation, 2020
Background: Deep brain stimulation (DBS) is an effective treatment for movement disorders, yet its mechanisms of action remain unclear. One method used to study its circuit-wide neuromodulatory effects is functional magnetic resonance imaging (fMRI ...

Abnormal neurovascular coupling induces glymphatic dysfunction in a mouse model of familial hemiplegic migraine type 2 [PDF]

The Journal of Headache and Pain
Migraine is a prevalent primary headache disorder that significantly impairs daily life. Recent imaging studies have suggested that chronic migraine may be associated with changes in the function of the glymphatic system.

Retinal Neurovascular Coupling in Diabetes [PDF]

Journal of Clinical Medicine, 2020
Neurovascular coupling, also termed functional hyperemia, is one of the physiological key mechanisms to adjust blood flow in a neural tissue in response to functional activity. In the retina, increased neural activity, such as that induced by visual stimulation, leads to the dilatation of retinal arterioles, which is accompanied by an immediate ...

Neurovascular Coupling in Development and Disease: Focus on Astrocytes

Frontiers in Cell and Developmental Biology, 2021
Neurovascular coupling is a crucial mechanism that matches the high energy demand of the brain with a supply of energy substrates from the blood. Signaling within the neurovascular unit is responsible for activity-dependent changes in cerebral blood flow.
