Gene Amplifies Brain Sensitivity to Light During Migraines

Researchers have identified a molecule in the brain called NEAT1 that plays a key role in light sensitivity, a common and painful symptom of migraines. NEAT1 disrupts the normal balance of nerve signaling by interfering with microRNA activity, leading to increased levels of a pain-related protein called TRPM3.
