This advance is a modest advance along the path of brain scanning. Detailed brain scanning would be useful to reverse engineer the brain as an massive engineering approach to achieving human level artificial intelligence Ray Kurzweil has online articles on his thinking about this and he has his book The Singularity is Near which lays out his arguments for this and the implications if he is right. Some ruminations on the Kurzweil proposal for reverse engineering the brain is here by Science Fiction author Cory Doctorow
Clinical researchers from the University of Pennsylvania Health System (UPHS) are the first to combine fMRI and PET scanning in radiology, creating a way to compare different measurements of the brain's function concurrently. This analysis could lead to better diagnosis and treatment in patients suffering from brain disorders, like Alzheimer's disease.
