Researchers at Washington University and the University of Illinois at Urbana-Champaign have developed miniaturized electronic devices small enough to safely insert into the brains of live mice. The tiny wireless devices can target specific brain cells and influence behavior.

University of Illinois materials scientist John Rogers co-led the study and helped design the devices. He says they’re on the same size-scale as cells, so they can penetrate far down into the brain.
