Using a banjo in brain surgery

On BBC and TED, I learned about the brain surgery of the musician Eddie Adhock. To treat a hand tremor that could threaten Mr. Adhock's abibilty to perform professionally, surgeons placed electrodes in Mr. Adcock's brain and fitted a pacemaker in his chest delivering a small current that shut down the region of his brain causing the tremors. To test the success of the procedure, Eddie Adcock played his banjo throughout the brain surgery process.
