Brain scans provide researchers clues in migraine study

A majority of the 30-million Americans who get migraines are extremely sensitive to light -- even those who are blind, but can still detect light.

Using brain scans, researchers traced the path of brain cells in lab animals during a migraine. They found exposure to light triggered a flow of electrical signals that converged on neurons already causing the migraine.

These findings could help them determine how to block that pathway so migraine patients would be able to endure light without pain.

The study was led by researchers at Beth Deaconess Israel Medical Center/Harvard University and published online in Nature Neuroscience.
