In brain surgery, a mistake can mean a disability or death. So how do you teach a neurosurgeon without mistakes? In this recent newscast by the Houston ABC affiliate KTRK, Christi Myers shows how Dr. Jaime Gasco uses a 3-D brain simulator. UTMB has one of only five simulators in the United States. In the first two UTMB studies, they found that medical students who were going into neurosurgery were 30 percent to 50 percent more accurate if they trained on the computer brain simulator.
