The scanners track the magnetic signals that neurons throw off as they communicate.
"You can look at how the networks of the brain talk to each other in real time" said Greg Simpson, the Director of the Neuroimaging Lab at University of California in San Francisco.
These scanners are very expensive at the moment,; they cost $2 million.
