You may know that flashing light can induce photosensitive epileptic seizures, but scientists are now discovering that some still images can trigger seizures as well.
Some researchers have hypothesized that our brains are not comfortable with extreme stripe patterns and doesn't know how to properly process these images. Looking at vertical lines can trigger a neural loop of brain activity, which in severe cases can lead to epilepsy.
Researchers think there may also be a link to vertical lines and migraines. The study authors believe that stripes in clothing, buildings or public artworks could be triggering disabling headaches, particularly in people who are already sensitive to light.
"Even perfectly healthy people may feel modest discomfort from the images that are most likely to trigger seizures in photosensitive epilepsy." said Dr. Dora Hermes
