![]() Some people suffer from seeing still patterns moving more than the rest of the population, and that is because they suffer with a condition called oscillopsia. The cause of migraines in 6 out of 10 patients is unknown, so the study into lines, visual patterns and gamma oscillations has provided new medical insight. ![]() For some people, the increased gamma oscillations could cause migraines and seizures, but might just bring on an uncomfortable visual sensation for those without epilepsy or susceptibility to migraines. They extended this finding to include buildings with repetitive brickwork, stripy clothing, artwork, and even objects around the home like radiators with lines. However, this 2017 study was the first time that scientists proved that still images have the same effect. It has been known for a number of years that flickering and bright lights can trigger epilepsy, particularly when viewed on a screen. This was proven when researchers distorted the harsh lines in their study, blurring the edges, and the gamma oscillations died down accordingly. Natural stripes, such as those on a zebra, don’t have the same effect as more geometric lines artificially produced by humans. The gamma oscillations occur because our brains aren’t equipped “ to cope with such extreme regularity”. Research suggests that this could be the trigger for some migraines and epileptic fits, with migraines affecting 9 million people in the UK and with 500,000 people suffering from epilepsy. But do we know the science behind it?Ī 2017 study found that when we look at “intensely stripy” patterns, there’s an increase of gamma oscillations in the brain. You’re certainly not the only one to experience this visual distortion brought on by harsh patterns, often causing an uncomfortable feeling in your eyes. Have you ever looked at a still stripy pattern and felt that it was moving in front of your very eyes? Maybe you had to strain your eyes particularly hard to focus on it and differentiate one stripe from the next.
