Awake Brain Surgery Lets Violinist Play While Doctors Work

Roger’s passion is the violin, but a neurological disorder called essential tremor (ET) makes it nearly impossible to play. To steady his hands, Roger underwent brain surgery that allowed him to play the violin while doctors fired signals into his brain to target the tremors. Dr. Bruce Hensel reports for the NBC4 News at 5 p.m. on Nov. 23, 2012.
