BOSTON (AP) - Scientists want to fix the things that go wrong inside your head. Their plan: Grow replacement parts for broken brains. They make it sound easy. Just brew a batch of gray matter. Drill a hole in the skull. Put in the new stuff. Wire it up like the original. Voila! New brains. Despite its whiff of mad scientist run amok, this scenario is surprisingly close to reality. Researchers can already do amazing things with mouse brains. And as they so fondly and frequently point out, mice really are an awful lot like us. Some human experiments already hint at what's possible. Since the 1980s, doctors have cautiously tested transferring brain cells from aborted fetuses to victims of Parkinson's disease. For some, it seems to work remarkably well, restoring lost control of movement. See http://www.infobeat.com/stories/cgi/story.cgi?id=2559385945-9a2
