Betterhumans investigates some of the new technologies that will allow us to better understand the aging process of the human brain. These developments are initially aimed at the early detection of neurodegenerative conditions such as Alzheimer's, but have the potential to greatly increase our understanding of how physical structure in the brain relates to thought, memory and mind. This sort of understanding, like that sought by the Allen Brain Atlas project, is a vital part of efforts to extend the healthy human life span. In the decades ahead, regenerative medicine will allow us to replace damaged organs - but not the brain. We must learn to repair and protect the human brain from the ravages of aging in situ.
