Flexible Circuit Injected Into Living Brains

"A Flexible Circuit Has Been Injected Into Living Brains":

Implanted via injection, a grid of wires only a few millimeters across can insinuate itself with living neurons and eavesdrop on their chatter, offering a way for electronics to interface with your brain activity.

“We’re trying to blur the distinction between electronic circuits and neural circuits,” says Charles Lieber, a nanotechnologist at Harvard University and co-author of a study describing the device this week in Nature Nanotechnology.
