Neurovascular Coupling: A Parallel Implementation [PDF]

open access: yesFrontiers 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 ...

Subarachnoid Hemorrhage, Spreading Depolarizations and Impaired Neurovascular Coupling [PDF]

open access: yesStroke Research and Treatment, 2013
Aneurysmal subarachnoid hemorrhage (SAH) has devastating consequences on brain function including profound effects on communication between neurons and the vasculature leading to cerebral ischemia.

Neurovascular Coupling in Development and Disease: Focus on Astrocytes

open access: yesFrontiers 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.

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

open access: yesCells
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]

open access: yesPeerJ, 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 ...

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

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

Real‐Time and High‐Resolution NIR‐II‐L Imaging of Netrin‐1‐Mediated Neurovascular Coupling Driven by Dose‐Dependent Electroacupuncture [PDF]

open access: yesAdvanced Science
Accumulating evidence implicates that disrupted ovarian neurovascular coupling is a vital driver for polycystic ovary syndrome. Electroacupuncture (EA), as a form of peripheral neuromodulation, offers a potential therapeutic avenue to restore this ...

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

open access: yesThe 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.

Low-intensity ultrasound stimulation modulates time-frequency patterns of cerebral blood oxygenation and neurovascular coupling of mouse under peripheral sensory stimulation state

open access: yesNeuroImage, 2023
Previous studies have demonstrated that transcranial ultrasound stimulation (TUS) not only modulates cerebral hemodynamics, neural activity, and neurovascular coupling characteristics in resting samples but also exerts a significant inhibitory effect on ...

Neurovascular coupling dysfunction of visual network organization in Parkinson's disease

open access: yesNeurobiology of Disease, 2023
Parkinson's disease (PD) has been showed perfusion and neural activity alterations in specific regions, such as the motor and visual networks; however, the clinical significance of coupling changes is still unknown. To identify how neurovascular coupling
