Investigating mechanisms of hemodynamic control in the brain Brenda R. Chen Neurovascular coupling is the relationship between neural activity and blood flow that allows the brain to exhibit increases in blood flow to areas of elevated neural activity during sensory stimulation. It is these localized changes in blood flow, collectively known as the hemodynamic response, that are detected by mod...

Neurovascular compression syndromes are usually caused by arteries that directly contact the cisternal portion of a cranial nerve. Not all cases of neurovascular contact are clinically symptomatic. The transition zone between the central and peripheral myelin is the most vulnerable region for symptomatic neurovascular compression syndromes. Trigeminal neuralgia (cranial nerve V) has an incidenc...
