Summary

This study uses a powerful 7T MRI scanner to look at brain structure and activity in people with migraine, visual snow, or epilepsy, as well as healthy volunteers. The goal is to better understand how these conditions affect the brain. No treatment or medication is tested—only observation and questionnaires.
