High-tech imagery helps surgeons combat epilepsy

After nearly seven hours of preparation, Dr. Joseph Madsen turned on the laser at Boston Children’s Hospital that would burn a tiny hole in the brain of 13-year-old Justin Griffin.

The laser was on for only a minute, but scored a direct hit on the area Madsen thought was causing Justin’s weekly epileptic seizures. Twice more the surgeon pulsed the laser, and then concluded the operation was a success: The left hippocampus of Justin’s brain had been effectively destroyed and with it the catalyst for the boy’s disruptive seizures.
