Wired reports on a major milestone: "Scientists have mapped every gene in the mouse brain as part of Paul Allen's Brain Atlas project launched in 2001. ... The brain atlas combines cellular-resolution scans of the mouse brain with precise information about which genes are expressed where. ... We have essentially mapped each individual gene in the mouse brain, about 21,000 genes in all, down to the cellular level. ... The nonprofit's directors [will seek] additional sources of public and private funding for the next big step: scanning human brain tissue." The aging brain is one of the greatest challenges of the decades to come for healthy life extension science. If we are to benefit from future advances in repairing tissue and biochemical systems, we must become very, very good at repairing the aging brain. Tools like the Brain Atlas are the first step towards the understanding and technologies that will make this possible.
