Why do lights cause seizures?
Certain patterns of light — flashing bright lights at particular frequencies — synchronize cells within the visual cortex. If the neurons then fire through their networks at too high a level, they can recruit other neurons into a hyper-synchronous discharge. That’s what happens in the brain during a seizure.
