The final step was to divert brain signals to a computer model that controlled the movements of a robot.

It can detect different brain signals with an accuracy of 99%.

But we don't know yet how well humans can control these brain signals.

Some researchers prefer to measure brain signals on the scalp.

A more difficult task is interpreting the brain signals for movement in someone who can't physically move their own arm.

This would be the fight-or-flight response that the body automatically receives from the brain signals.

So - your heart runs on automatic most of the time, but responds to brain signals when it needs to.

"Those brain signals seem to be of a particularly high quality in dancers," he said.

This technology uses these brain signals to control computer functions.

"Rather than cut off his brain signals, why not tune in on the frequency?"
