At Joyce: Noticed on this net a day or so ago that OHSU (Oregon Medical School) was participating in the GDNF trials. I think Dr. John Nutt was mentioned,head of the movement Disorders Clinic. The only number I have is Dr. Burchiel's office--the neurosurgeon who did Gordon's thalomotomies. It couldn;t be any farther away, could it, but they must know who else is participating.. Just in case it helps. Dr.B's office number is 503-494-8070.
