How do you map a brain? By examining its structure? Its connections? Its distinct cell types? Like mapping the Earth, scientists have found that mapping the human brain is an imperfect science, and there’s no single simple approach. However, using MRI measurements of 210 healthy young adult brains, a team of neuroscientists led by Mathew Glasser of Washington University Medical School may have recently completed the most comprehensive brain rendering yet. By aggregating many different ways of looking at and measuring the brain, the team has located dozens of previously unidentified regions. You can read more about the study at Nature.
