About a year ago, I had a really bad migraine that I just couldn’t shift. I’d had migraines before but, over the course of two weeks, this one kept coming back.
As a neuroscientist, whose research has covered what happens to the brain during migraine, I was determined to get to the root of the problem. I tried all sorts: I had my eyes tested, and I even went to the dentist to make sure it wasn’t something going on with my teeth and causing a headache.
Eventually, I identified the culprit: stripes. It turned out that around the time the migraine had started, my wife had bought lots of stripy tops, some with tightly-packed black and white lines, which she’d taken to wearing. (We’ll come back to why this triggered the migraine later.)
