I have read yesterday's message of Jeffrey and subsequent requests of informations. I had also got some vague news about this "different" approach to relieveing pain (physical instead of chemical) talking to my "allergologist" (then he is not in the field!!!); he made the following remarks which I think of interest: 1) the system acts with a switch and can be turned on/off when one pleases 2) It apprently stops/reduces tremor and has a minor side effects: in some cases (not all) it may render speech a bit more difficult (but You can turn it off to speak on the telephone and turn it on to eat) I then decided to try searching our "list". I searched for "electric" and got back many messages and amongst them there is a digest of scientific references with short abstracts that indicates that this (or variation of this) has been and is being performed in Grenoble (France) since a while. The message is Number 3430 "Deep Brain Stimulation References" There are also other two messages 4758 4831 "Thalamic stimulation Systems" that can be of interests. (Sorry I printed the files and deleted them and lent the printout to my sister... so I cannot be more specific.!!!) It would be good if someone that has access to the scientific magazines referred there could post larger excerpts. I think that if someone has access to more explicatory, lay scientific description it would be of great help. I will also try to see if I can get some comments from peoples who have used the device.
