Reference is made to the paper quoted below: It is interesting that the field they used is relatively weak (.34T, .57T and .80T) and now I am curious what the field is which is using for MRI's. I am not aware of any changes reported as a result of taking an MRI for any condition Parkinson or otherwise. Also I do not know what the time evolution of the field is for the MRI system (compared to the report in this paper). My initial reaction is somewhat negative. I also looked at the U. of Glasgow site (co-author: Stone). No such name showed up. I sent a note to the dept of Neurology asking for more information. No answer yet. I sent the following request to the address given in the reference which Hans found. Unfortunately the mail was returned. Could you send a copy of your article referenced below: J Neurosci Res 1999 Sep 15;57(6):935-40 PMID: 10467265 Therapeutic and "dose-dependent" effect of repetitive microelectroshock induced by transcranial magnetic stimulation in Parkinson's disease.
