It's not quite Google Maps, but the new optic still provides the most detailed understanding of the cerebral cortex to date, based on the freshest data from the latest technologies. The new map "is a major revision and updating” of previous maps, "said David Van Essen, senior author of the study. "Most of the new areas are in regions we associate with higher cognitive function,” he said. This is version 1. 0, and as new data comes in, there will be revisions, said Dr. Greg Farber, director of technology development at the National Institute of Mental Health, echoing the authors of the research.
