Mayo Clinic Minute - Brain mapping improves surgical outcomes

Just like a traveler uses a road map to find the most appropriate route to a destination, Mayo Clinic neurosurgeons are using a different kind of map to determine the best way to operate on the brain. Using imaging, such as an MRI, doctors determine the areas of your brain that control vision, language and movement — making surgery more precise and preserving those brain abilities. To map the brain, a patient is given instructions on a monitor while in the scanner.
