Michael, you had mentioned Alzheimer's as well and some of the commonalities. I'm curious about that, because as we look at the national strategy on the brain, obviously the hope at the beginning, I think, was that we could find areas in which to invest in order to help all these neurological disorders.
What type of research do you think is available, and what possibilities exist? It's always interesting to hear what possibilities would be available if the research could be funded in a much larger context. What research studies might cross both areas?
