New imaging techniques probe brain’s long-range connections

by  /  10 June 2013

New techniques to scan the brain can produce exquisitely detailed views of white matter, which contains the long cellular fibers that connect neurons. Many of the advances are emerging from the Human Connectome Project, a five-year push to map the brain’s wiring.
