A group of Harvard scientists has developed new methods of magnetic resonance imaging (MRI) to look more closely inside the human brain. The resulting images are stunning!

Jan Wedeen, who developed one technique, says that up until now we’ve just been seeing “a shadow of [the brain’s] surfaces” and only now can we truly see the pathways of the brain. Jeff Lichtman, who came up with a related technique, has been using scans to trace connections between brain cells by tagging them with different colors.
