Jon Hamilton http://kuow.org en One Scientist's Quest To Vanquish Epileptic Seizures http://kuow.org/post/one-scientists-quest-vanquish-epileptic-seizures In the early 1990s, a young brain researcher named <a href="http://www.anatomy.uci.edu/solteszres.html">Ivan Soltesz</a> heard a story that would shape his career.<p>His adviser told him about a school for children whose epileptic seizures were so severe and frequent that they had to wear helmets to prevent head injuries. The only exception to the helmet rule was for students who received an award.<p>"The big deal for them is that they can take the helmet off while they're walking across the stage," Soltesz says.

There was the time he fell "headfirst on a marble floor" and got a concussion, the day someone stole the family car ("my dad had to chase it down the block"), or the morning he found a black bat (the furry kind) in the house.<p>But Francis looks puzzled when his mom, Joanne Csedrik, asks him about a family trip to the Philippines when he was 3. "It was to celebrate someone's birthday," she tells him. "We took a long plane ride, two boat trips," she adds.
