Last year, Gary Olhoeft had DBS surgery to control his Parkinson's disease symtoms. It has been a success for him and is controlling his symptoms without the severe side effects from the medication that had become worse than the disease for him.
Gary is also a geophysicist and he has been able to invent ways to monitor the electromagnetic interference that can affect his DBS system. The following YouTube videos are of a talk that Gary gave to EMR Policy Institute in December of 2009. These Are good and important to watch even if you don't have any medical implants!
Thank you Gary for sharing your knowledge with all of us!
