"U.S. Senator Edward Kennedy."
Kennedy remained awake and alert during the entire procedure, doctors said. By keeping him awake, they were able to map the brain's key areas, like those that control movement and speech, and avoid cutting into them. His doctors were also able to use "neuronavigation techniques" to map his brain's cancerous areas. Doing this helped surgeons to better target the cancer and get all of it out.
Medical researchers have learned a lot about the brain in recent years, especially about the relationships between the brain's structure and functions. Understanding the brain has revolutionized diagnosis, treatment, and further research of a variety of conditions, including brain cancer and Alzheimer's disease. In this lesson, your own investigations will discover how exactly the brain works within the larger network of the nervous system.
