A banjo as a brain surgery instrument

Yes, that's right...the title is correct: a banjo can be used as a valuable brain surgery instrument.

Eddie Adcock is one of the pillars of Bluegrass Music. Recently he realised that a new found tremor in his hand could threaten his ability to perform professionally. So, he underwent brain surgery to treat the hand tremor and to test the success of the procedure, he played his banjo throughout the entire operation.

Surgeons placed electrodes in Adcock's brain and fitted a pacemaker in his chest which delivers a small current that shuts down the region of his brain causing the tremors.
