I can tell you that the reason strobe lights can cause seizures is because the parts of the brain used to process the information is unable to do it fast enough therefore cuasing a person prone to seizures and sometimes those that aren’t to have one.

Welcome - I imagine you’re commenting on the column [Why do theaters warn audiences when a strobe is used in a play?](http://www.straightdope.com/classics/a2_423a.html)

Could you expound on your post? It’s fairly vague, and we don’t mind long stories here. 🙂

That makes no sense; photoepileptics can be set off by frequencies as low as 2 Hz, which we are easily capable of processing.
