What are some pictures that I could use on my epilepsy project poster?

So I'm doing a project on epilepsy and I've already gotten my essay down and everything. The problem is that I have to bring in some kind of visual representation of my subject, so I chose a poster. I don't know what kind of pictures or diagrams I should include. Does anyone know of any good sites that I could obtain EEG scans or maybe some good pictures of the epileptic brain compaired to the normal brain? Any other ideas would also be great! Thank you.
