A man is paralyzed from the neck down, yet with a microchip implanted in his brain, he can move the computer cursor and check his email. So far, only four patients are enrolled in this study at Brown University.
Scientists are excited that microchips in the minds of paraplegics can read electrical signals that tell the brain what movements to make and then after the signals are processed, they move. So, the patient can just think about moving his hand and he does. At least that's the plan. The chip is still far from perfect.
"Our goal is to have precision that would be just like our ability to operate a computer mouse and point and click very accurately, and currently, it's less than that," said Dr. John Donoghue, of Brown University.
Dr. Dondaghue says there are still a lot of kinks to work out. So, this is promising but it will be some time for the microchip for paralysis is widely available.
