Brain-computer interface(BCI) technology could help people with disabilities send commands to machines.Recently, two researchers, Jose Milan and Michele Tavella f
2、rom the Federal Polytechnic school in Lausanne, Switzerland, demonstrated a small robotic wheelchair directed by a persons thoughts.In the laboratory, Tavella operated the wheelchair just by thinking about moving his left or right band. He could even talk as he watched the vehicle and guided it with
3、 his thoughts.“Our brain has billions of nerve cells. These send signals through the spinal cord （脊髓）to the muscles to give us the ability to move. But spinal cord injuries or other conditions can prevent these weak electrical signals from reaching the muscles,” Tavella says. “Our system allows disa
4、bled people to communicate with external world and also to control devices.”The researchers designed a special cap for the user. This head cover picks up the signals from the scalp(头皮) and sends them to a computer. The computer interprets the signals and commands the motorized wheelchair. The wheelc
5、hair also has two cameras that identify objects in its path. They help the computer react to commands from the brain. Prof. Milan, the team leader, says scientists keep improving the computer software that interprets brain signals and turns them into simple commands. “The practical possibilities tha

10、out How the Human Brain WorksC. BCI Could Mean More Freedom for the DisabledD. Robotic Vehicles Could Help to Cure Brain Injuries BIn the fall of 1985, I was a bright-eyed girl heading off to Howard University, aiming at a legal career and dreaming of sitting on a Supreme Court bench somewhere. Twen
11、ty-one years later I am still a bright-eyed dreamer and one with quite a different tale to tell.My grandma, an amazing woman, graduated from college at the age of 65. She was the first in our family to reach that goal. But one year after I started college, she developed cancer. I made the choice to

There certainly were times I wanted to quit, but I
15、 knew I should set an example for them to follow through the rest of their lives.In 2007, I graduated from the University of North Carolina. It took me over 21 years to get my college degree！I am not special, just single-minded.
