Researchers Making Strides With Bionic Limbs

Robotic limbs -- moved by thought. It's not science fiction. It's a reality. A bionic brain chip is being tested by researchers right now!

A tiny computer chip is making it possible for your thoughts to control an object outside of your body.

Dr. Andrew Schwartz from the University of Pittsburgh said, "We intercept signals from the brain and we use them to control an external device." He said, "It should work as easily as moving your own limb. Here's how it works."

Dr. Schwartz explains, "First, electrodes are implanted in the subject's brain. Then a transmitter is attached to a computer where those brain signals are read. They're then decoded, sent to another computer where those thoughts are turned into action."

He said this whole thing will fit into the skull and the hole will actually go through and into the brain, and they can even by-pass damaged brains or nerve cells.

"Because we can record these signals from many parts of the brain if one region is damaged. It's very likely we can use another region of the brain to capture these signals from," explained Schwartz.

Brain Machine Interface, or BMI is already being tested in humans with promising results.
