Sheffield people are smarter. How else do you explain the city's position as a global leader in neurosurgery?
Recently, the city acquired three new SonoWand brain scanners, which are among the most sophisticated in the world. The first in the UK, the scanners produce three-dimensional images of the brain in real time during surgery, which makes it easier for surgeons to detect and remove growths without damaging healthy tissue. Crucially, the scanners are helping attract even more top brain surgeons from across the world who will use the scanners to develop new surgical techniques.
And that means that even those people in Sheffield who aren't brain surgeons will be able to keep their brains in top shape.
