The role of nitric oxide in neurovascular coupling
Journal of Theoretical Biology, 2016Nitric oxide (NO) is a neurotransmitter known to act as a potent cerebral vasodilator. Its role in neurovascular coupling (NVC) is discussed controversially and one of the main unanswered questions is which cell type provides the governing source of NO for the regulation of vasodynamics.

Investigating static nonlinearities in neurovascular coupling
Magnetic Resonance Imaging, 2011Many statistical models of coupling between time changes of the band-limited power of neural signals and functional magnetic resonance imaging Blood Oxygenation Level Dependent (BOLD) signal time changes rely on linear convolution. The effect of nonlinear behaviors in single-trial relationships between neural signals and BOLD responses is rarely tested

Neurovascular Coupling During Spreading Depolarizations
2012Injury depolarizations akin to spreading depression of Leão are important in the progression of tissue damage in ischemic stroke, intracranial hemorrhage, and trauma. Much of the research on injury depolarizations has been focused on their origins, electrophysiological mechanisms, and metabolic impact.

Metabolic Aspects of Neurovascular Coupling
1997In the previous chapter it was demonstrated that functional neuroimaging relies on the coupling of neuronal activity and cerebral blood flow. What is the function of neurovascular coupling? Does it serve to provide a constant glucose or oxygen delivery to brain cells? Does it mainly regulate removal of tissue metabolites such as lactate?

Angiotensin and Neurovascular Coupling: Beyond Hypertension
Microcirculation, 2015AbstractBrain homeostasis is dependent upon the constant perfusion of oxygen and nutrients through CBF. The mechanism responsible to couple CBF to neuronal activity is termed NVC. Ang II, a key player in hypertension, impairs NVC and has been found to be of significant importance in neurodegenerative diseases, such as AD. The presence of Ang II and its
