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

Neurovascular Uncoupling Is Linked to Microcirculatory Dysfunction in Regions Outside the Ischemic Core Following Ischemic Stroke

open access: yesJournal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2023
Background Normal brain function depends on the ability of the vasculature to increase blood flow to regions with high metabolic demands. Impaired neurovascular coupling, such as the local hyperemic response to neuronal activity, may contribute to poor ...

Age-Dependent Impairment of Neurovascular and Neurometabolic Coupling in the Hippocampus

open access: yesFrontiers in Physiology, 2018
Neurovascular and neurometabolic coupling are critical and complex processes underlying brain function. Perturbations in the regulation of these processes are, likely, early dysfunctional alterations in pathological brain aging and age-related ...

Neurovascular coupling during deep brain stimulation

open access: yesBrain 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 ...

Modeling the relationship between neuronal activity and the BOLD signal: contributions from astrocyte calcium dynamics

open access: yesScientific Reports, 2023
Functional magnetic resonance imaging relies on the coupling between neuronal and vascular activity, but the mechanisms behind this coupling are still under discussion.

Lower neurovascular coupling response despite higher cerebral blood flow at rest in apolipoprotein ɛ4 positive adults.

open access: yesPLoS ONE
Cerebral blood flow at rest declines with age. However, age-related changes in functional measures of cerebrovascular health including cerebrovascular reactivity and neurovascular coupling are not well understood.

Neurovascular and Neurometabolic Derailment in Aging and Alzheimer’s Disease

open access: yesFrontiers in Aging Neuroscience, 2015
The functional and structural integrity of the brain requires local adjustment of blood flow and regulated delivery of metabolic substrates to meet the metabolic demands imposed by neuronal activation.

Exploring the translational impact of type 1 diabetes on cerebral neurovascular function through ECoG-LSCI

open access: yesAPL Bioengineering
Type 1 diabetes mellitus (T1DM) can result in complications such as retinopathy, nephropathy, and peripheral neuropathy, which can lead to brain dysfunction.

Resting state BOLD-perfusion coupling patterns using multiband multi-echo pseudo-continuous arterial spin label imaging

open access: yesScientific Reports
The alteration of neurovascular coupling (NVC), where acute localized blood flow increases following neural activity, plays a key role in several neurovascular processes including aging and neurodegeneration.
