Reduced oxygen supply to the prefrontal cortex during the Stroop task in migraine patients with aura: A preliminary functional near-infrared spectroscopy study.

The role of the cerebrovascular system in migraine pathogenesis is critical. Several studies have demonstrated alterations in the regional cerebral blood flow that persist during headache-free intervals. In the present study, we aimed to measure the prefrontal hemodynamic responses to the cognitive task in interictal episodic migraineurs.
