Obama and DARPA want to map the human brain like we've mapped the human genome

Here are a couple different perspectives on the big news out of Washington this afternoon — an ambitious Obama Administration proposal to appropriate $100 million to begin a project to "map the brain". What's that mean? We have a lot of good data on single neurons. We have a lot of good data on what happens in the brain, as a whole, during certain tasks. What we don't really understand is how those individual neurons work together as networks or what activity in the brain really means on the level of causality and processing. That's what this project would be aimed at understanding. At LiveScience, Stephanie Pappas puts the project into scientific (and financial) context. At Nature News, Meredith Wadman writes about why some scientists are wary of this plan.
