Music therapy has helped Gabrielle Giffords relearn how to talk.  As Dr. Oliver Sacks, professor of Neurology at Columbia University, explains, "Nothing activates the brain so extensively as music." When a person can't speak, they can still sing, because a different part of the brain is involved. Seeing the transformation in Congresswoman Giffords-- and the integral role music played-- was truly inspiring to watch.
