President Barack Obama announced a new multi-year research initiative to map the human brain. He compared its potential to that of the Human Genome Project. Scientists hope the brain project will eventually lead to solutions to diseases like Alzheimer's and Parkinson's and better treatments for a range of mental illnesses. The National Institutes of Health will coordinate the project. The president wants Congress to approve $100 million in initial funding. Some critics argue the money could be better spent on smaller grants to a number of brain research projects with specific goals. But many scientists are enthusiastic. Join Diane and NIH Director Francis Collins for a discussion on mapping the human brain.
