Ivan I had a pallidal stimulation operation where probs , through which an electrical impulse is passed by batteries surgically implanted under the skin, stimulates the region where a pallidotomy is usually performed. I can now turn my tremor on or off with a pass of a magnet over the batteries. It is like the difference between night and day. My body does seem to override the impulse under extreme stress or excitement(for example , watching Jayhawk basketball). I also turn the device off at night to help conserve the battery. I take Klonopin to help me sleep. Dick Swindler (52/15)
