You might try a 'google search' on 'deep brain stimulation'. There are several reputable sites. I imagine you are also looking for real-life experiences. I have not had dbs, but know a lot of folks who have. Medtronic is the company that makes the hardware. They have real-life stories on their site - biased, I'm sure, but good info. The Medtronic site with info on DBS for PD is http://www.medtronicdbs.com/parkinsons/
