Significats de neurovascular coupling en anglès

The mechanisms of neurovascular coupling underlying generation of BOLD fMRI signals remain incompletely understood.

As a result of neurovascular coupling, ASL provides a useful marker of resting neuronal activity.

This neurovascular coupling underlies blood oxygen level-dependent functional imaging signals, but its mechanism is controversial.

Overall, neurovascular coupling during optogenetic control of glutamatergic neurons largely conforms to that of a sensory stimulus.

Within this framework, the problems of signal-to-noise ratio, data analysis strategies, motion correction, and neurovascular coupling are considered.

These results indicate that HFD negatively affects neurovascular coupling and cerebrovascular function even in the absence of dyslipidemia.

Due to the nature of neurovascular coupling, hemodynamic signals are known to spread beyond the locus of metabolic activity.

This study is designed to assess the specific characteristics of neurovascular coupling to auditory stimuli in healthy and ill neonate brains.

The purpose of this study was to investigate how concussion history affects neurovascular coupling in Special Operations Forces (SOF) combat Soldiers.

Despite no main effect of concussion history on neurovascular coupling response in SOF combat Soldiers, we observed a dose-response based on lifetime concussion incidence.

Lastly, we discuss recent experimental innovations that have enabled the study of neurovascular coupling and brain-wide circuit function in un-anesthetized and behaving animal models.

Here, we review work showing that neurovascular coupling and brain circuit function in the awake animal are profoundly different from those in the anesthetized state.

While there has been extensive study of neurovascular coupling in anesthetized animal models, anesthesia causes large disruptions of brain metabolism, neural responsiveness and cardiovascular function.

In diabetic rats, the spatial disconnect between subnormal DeltaPo2 pansuperiorly and retinal thinning only superiorly to the optic nerve suggests that neurovascular coupling is perturbed.

Neurovascular coupling studies are widely conducted in anesthetized animals using functional magnetic resonance imaging (fMRI).
