Mediums – people who say they can channel spirits or other supernatural beings to communicate with the living – often get a bad rap. They’re the subjects of debunking attempts, they’re accused of fraud, and most people think they’re just plain odd. But what if we deferred our judgments and tried to find out just what’s actually going on physically and neurologically in the act of channeling? A team of researchers in the US and Brazil did just that, finding that, whatever else is happening, mediums show some very unique patterns of brain activity. And even more interestingly, those patterns differ depending on the mediums’ amount of experience.
