The Decade of the Brain was a designation for 1990-1999 by U.S. president George H. W. Bush as part of a larger effort involving the Library of Congress and the National Institute of Mental Health of the National Institutes of Health "to enhance public awareness of the benefits to be derived from brain research".
The interagency initiative was conducted through a variety of activities including publications and programs aimed at introducing Members of Congress, their staffs, and the general public to cutting-edge research on the brain and encouraging public dialog on the ethical, philosophical, and humanistic implications of these emerging discoveries.
