This story regarding an autopsy to be performed on Terri Schiavo quotes a Wayne State department chairperson. \"...The autopsy will not overrule the long-standing diagnosis that the 41-year-old Florida woman was in a persistent vegetative state. That is a determination based on a physician\'s observation and interaction with the patient, not on the condition of brain tissue, said Dr. Robert Lisak, chairman of the department of neurology at Wayne State University School of Medicine in Detroit.\"
