Scientists have implanted a wireless device the size of a peppercorn inside mice to stimulate nerves.
The technique combines optogenetics—using light to control the activity of the brain—with a newly developed method for wirelessly powering implanted devices. It’s described in a paper published in Nature Methods.
“This is a new way of delivering wireless power for optogenetics,” says Ada Poon, an assistant professor of electrical engineering at Stanford University. “It’s much smaller and the mouse can move around during an experiment.”
