Bethesda, MD: Author.http://www.nimh.nih.gov/health/publications/the-teen-brain-still-under-construction/index.shtmlhttp://hdl.handle.net/11212/1774One of the ways that scientists have searched for the causes of mental illness is by studying the development of the brain from birth to adulthood. Powerful new technologies have enabled them to track the growth of the brain and to investigate the connections between brain function, development, and behavior.
