'The Team Knew It Had Electrodes In the Right Spot When the Musician's Performance was Steady.'
It's common for brain surgery patients to stay awake. That's how surgeons know everything is going smoothly, after all. When concert violinist Roger Frisch started suffering from tremors that are only a problem when he's playing, however, Mayo Clinic doctors had to resort to some rather unusual technology to find out if they were installing the necessary brain pacemaker correctly. The surgical crew gave Frisch a bow equipped with a motion-tracking sensor and asked him to fiddle during the operation; the team knew it had electrodes in the right spot when the musician's performance was steady.
