To: INTERNET:[log in to unmask] Corrections to my <Implant Surgery Experience> of Tue, 6 Aug 1996 14:03:48 -0400 last paragraph: I asked my neurologist why an implant and not a pallidotomy or thalamotomy. Answer: If the implant would not work, I would still be able to have a pallidotomy or thalamotomy; if I had a pallidotomy or thalamotomy first it would close any chance for an implant. The implant does not change the virgin nature of the brain.
