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

Scientific 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.

Neurovascular Coupling in Pregnancy and the Risk of Preeclampsia [PDF]

Stroke, 2014
Background and Purpose— This study investigated whether a short testing of neurovascular coupling during midterm pregnancy could identify women at risk for subsequent preeclampsia. Methods— Transcranial Doppler sonography of the posterior cerebral artery during a brief visual ...

Neurovascular and Neurometabolic Derailment in Aging and Alzheimer’s Disease

Frontiers 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.

Autoregulation of the Human Cerebrovasculature by Neurovascular Coupling [PDF]

, 2013
Functional hyperaemia is an important mechanism by which increased neuronal activity is matched by a rapid and regional increase in blood supply.
