Dear Will: Thanks for replying to the request for names of PD research institutions. It obviously should have been the other way around: my asking you, as you are better informed than I. Sarratt is closed as a college for teaching choral singing in Nashville. However,the Nashville Opera Chorus, which participated superbly in Beethoven's Fidelio last night has evolved into a first class opera. chorus. Kenneth Schermerhorn is becoming a disciplined, hardworking and imaginative conductor. I did not list some of the great movement disorder clinics, as your location would indicate that you were already aware of them. Finally, I would not yet classify Vanderbilt in that class. I would like to see more long-term results from their thalamus stimulation studies. I would appreciate hearing from you sometimes about Vanderbilt. It is not unlikely that I will have to chose to be a thalamotomy patient. With best wishes, Steven; (615-383-4831) Steven E. Mayer, Ph.D.
