Brain surgeon Kenneth Follett had never received thank-you cards from his patients after performing an operation — until he started putting electrodes in their brains.

That shortage results in movement problems. After surgery, many patients are suddenly able to get around, do household chores and even go shopping, Follett says. “It has the potential to change people’s lives.”
