Researchers from the University of Minnesota Medical School and Brain Sciences Center at the Minneapolis VA Medical Center have identified a noninvasive and painless way to diagnose complex brain diseases. And it’s as simple as staring at a point of light. The research offers promise for a less-stressful, painless, and objective diagnosis for brain diseases, as well as a way to measure the effectiveness of different treatments for these diseases. Using magnetoencephalography (MEG) to record tiny magnetic fields in the brain, the researchers recorded brain cells communicating with each other while research subjects stared at a point of light.
