Hi Gaylon Sorry the adress I gave you did not respond. The article to which I referred was on the Neurology Web Forum,which has the URL http://demOnmac.mgh.harvard.edu/neurowebforum/neurowebforum.html but today I got no response. Ulf Rollson wrote he worked on the neur. of the Lynkoping University hospital. In Swedish this is Universitetssjukhuset.I got this on my screen. The URL is http://www.lio.se./us/Main.html . When I clicked on this it again gave no response. Lucikly I have more talent for being stubborn than paranoid,so I will t ry tomorrow again. ida
