New brain-scanning technique allows scientists to see when and where the brain processes visual information

Every time you open your eyes, visual information flows into your brain, which interprets what you're seeing. Now, for the first time, MIT neuroscientists have noninvasively mapped this flow of information in the human brain with unique accuracy, using a novel brain-scanning technique.This technique, which combines two existing technologies, allows researchers to identify precisely both the location and timing of human brain activity.
