How Stem Cells Can Be Used to Pair Computers and Prosthetic Devices to the Nervous System

Researchers have turned stem cells into muscle cells and linked those muscle cells with tiny electrodes. When they're implanted into a nerve, the nerves wire themselves up to the muscles and can activate them. This technique has allowed the team to get around the existing problem that normally when you plant electrodes alongside nerves, a build-up of scar tissue subsequently blocks the detection of these signals.
