Researchers in England are working to combine two high-tech tools — high-speed eye-tracking and electroencephalography (EEG) brain recording — to understand what's happening in the brain while the eyes are moving.

 

Electroencephalography involves placing sensors on a person's scalp to record the electrical murmurs of the brain's many neurons. The researchers measure EEG while simultaneously measuring eye movements. [5 Crazy Technologies That Are Revolutionizing Biotech]

 

"This is actually a very challenging task, because whenever we move our eyes, this introduces very large artifacts into the EEG signal," said neuroscientist Matias Ison of the University of Leicester in England, who is part of the research team.
