Cathy Hutchinson has not been able to move her arms, legs or speak since suffering a stroke nearly fifteen years ago. Recently, she learned how to control a robotic arm using her thoughts. She now can use brain activity to serve herself a drink. The American woman is one of the two people who took part in a research project known as BrainGate2. The researchers have spent years studying how to help people like Cathy Hutchinson regain movement.
People who are paralyzed (瘫痪的) have their brain disconnected from their body. The idea of the project is to bypass that damaged nervous system. The two paralyzed people had small sensors connected to the part of the brain that controls movement. The devices measured brain activity and sent that information to a computer. The computer has special software that turns the information into digital commands for operating other devices. The researchers used a highl developed robotic arm to recreate human actions.
John Donoghue is a neuroscientist at Brown University, and the Department of Veterans Affairs. He was part of the project. He says the latest development of using robotic arms is a major victory. A video of the latest experiment shows Cathy Hutchinson using the robotic arm to pick up a cup of coffee. She guides the cup toward her mouth, moves it forward and drinks through a straw. Lead investigator Leigh Hochberg says the first time she did it was a magical moment. He said, “It was an incredible moment to see her with that robotic arm reach out and pick up that cup of coffee and serve herself that coffee for the first time in nearly fifteen years.”
