Dr. Samir Bangalore, left, a neurologist who specializes in epilepsy treatment at Sunrise Hospital & Medical Center, performs a test to carefully map the language functions of Chris Stones' brain after his first surgery Monday, July 20, 2009. The test will help determine the exact location of the seizures, and make sure that no essential language or motor functions are stored in that part of the brain, so that the neurosurgeon can remove that part of the brain during a second surgery.
