Altered Neurovascular Coupling in Unilateral Pulsatile Tinnitus

Frontiers in Neuroscience, 2022
ObjectiveAltered cerebral blood flow (CBF) and regional homogeneity (ReHo) have been reported in pulsatile tinnitus (PT) patients. We aimed to explore regional neurovascular coupling changes in PT patients.Materials and MethodsTwenty-four right PT ...

Unraveling the brain's response to hypoglycemia : Neurovascular coupling

Functional magnetic resonance imaging has suggested the possibility that hypoglycemia could interfere with neurovascular coupling. Here we discuss the implications of a study by Nippert and colleagues showing that hypoglycemia does not impair ...

Integrative neurovascular coupling and neurotransmitter analyses in anisometropic and visual deprivation amblyopia children

iScience
Summary: The association between visual abnormalities and impairments in cerebral blood flow and brain region potentially results in neural dysfunction of amblyopia. Nevertheless, the differences in the complex mechanisms of brain neural network coupling

Neurovascular coupling is preserved in chronic stroke recovery after targeted photothrombosis

NeuroImage: Clinical, 2023
Functional neuroimaging, which measures hemodynamic responses to brain activity, has great potential for monitoring recovery in stroke patients and guiding rehabilitation during recovery.

Non-invasive, multimodal analysis of cortical activity, blood volume and neurovascular coupling in infantile spasms using EEG-fNIRS monitoring

NeuroImage: Clinical, 2017
Although infantile spasms can be caused by a variety of etiologies, the clinical features are stereotypical. The neuronal and vascular mechanisms that contribute to the emergence of infantile spasms are not well understood.

Neurovascular Coupling in Type 2 Diabetes With Cognitive Decline. A Narrative Review of Neuroimaging Findings and Their Pathophysiological Implications

Frontiers in Endocrinology, 2022
Type 2 diabetes causes substantial long-term damage in several organs including the brain. Cognitive decline is receiving increased attention as diabetes has been established as an independent risk factor along with the identification of several other ...

Structure and function of neurovascular unit in arterial hypertension

Frontiers in Molecular Neuroscience
Arterial hypertension is considered a main risk factor for cognitive impairment and stroke. Although chronic hypertension leads to adaptive changes in the lager cerebral blood vessels which should protect the downstream microvessels, profound changes in ...

Assessment of neurovascular coupling and cortical spreading depression in mixed mouse models of atherosclerosis and Alzheimer’s disease

eLife, 2022
Neurovascular coupling is a critical brain mechanism whereby changes to blood flow accompany localised neural activity. The breakdown of neurovascular coupling is linked to the development and progression of several neurological conditions including ...

Evaluation of Cerebral Microvascular Regulatory Mechanisms with Transcranial Doppler in Fabry Disease

Brain Sciences, 2020
Background: Fabry disease (FD) causes cerebrovascular disease (CVD) even if asymptomatic, and this is why it is important to identify non-invasive methods to monitor the disease. We evaluated the usefulness of the cerebral autoregulation, vasoreactivity,

Loss of Caveolin-1 Impairs Light Flicker-Induced Neurovascular Coupling at the Optic Nerve Head

Frontiers in Neuroscience, 2021
Glaucoma is a neurodegenerative disease, which results in characteristic visual field defects. Intraocular pressure (IOP) remains the main risk factor for this leading cause of blindness. Recent studies suggest that disturbances in neurovascular coupling
