Thank you very much to our presenters today for stimulating a great discussion.
Dr. Smith, it seems to me that brain development in adolescents ought to be important, certainly to parents and to society. We want people who are cognitively efficient and able to perform important tasks in our society.
Dr. Smith, at what stage is your research now? It started many years ago with Dr. Fried, and you're following up now with 16- to 18-year-olds. Is this research ongoing? What are the next steps in research to help define or better define what's happening in the brain with myelination, with the neural interconnections, and what negative effects might be taking place in that important developmental process?
