Brief Summary:
Studying Carbon monoxide effects on brain vessels in healthy volunteers with magnetic resonance imaging.

Condition or disease Intervention/treatment Phase
Headache Disorders Other: Carbon monoxide Not Applicable

Detailed Description:
In this study we will systematically investigate the headache-releasing properties of carbon monoxide as well as measure the effect of carbon monoxide on mean blood flow rate in the brain's large vessel with magnetic resonance imaging. These studies are important for understanding and further investigating the carbon monoxide's headache-releasing effect in healthy subjects.
