here's a resource, haven't studied DBS since not at that point yet but they seem to put out a lot of info
http://www.centerformovement.org/

another source, dr. okun imho seems to be a proponent of DBS. I read his new book and he discusses it in length. not pushing the book but published recently.

sometimes you can get information overload. but DBS isn't something to take lightly, seems what happens after the surgery, follow up visits, programming skills of the clinicians, is just as important.
