Deep brain stimulation offers hope for patients with essential tremors, but the surgeons must be guided by the patient himself. For Roger Frisch, that meant playing the violin while having brain surgery.
With his career in jeopardy, Frisch sought out neurosurgeons at Mayo Clinic. Their solution: A technique called deep brain stimulation, which involved implanting electrodes deep inside the brain. But in these operations, surgeons must be guided by the reactions of the patient and, in Frisch's case, that meant performing a concert as surgeons stimulated his brain so they could tell whether the technique was working.
