【题目】Since the 1970s, scientists have been searching for ways to link the brain with computers. Brain-computer interface (BCI) technology could help people with disabilities send orders to machines.

Recently, two researchers, Jose Millan and Michele Tavella from the Federal Polytechnic School in Lausanne, Switzerland, showed a small robotic wheelchair directed by a person's thoughts.

In the laboratory, Tavella operated the wheelchair just by thinking about moving his left or right hand. He could even talk as he watched the wheelchair and guided it with his thoughts.

“Our brain has billions of nerve cells(神经细胞). These send signals through the spinal cord (脊髓)to the muscles(肌肉) 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 disabled people to communicate with outside world and also to control the machine.”

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 understands the signals and directs the motorized wheelchair. The wheelchair also has two cameras that recognize objects in its path. They help the computer react to orders from the brain.

Prof. Millan, the team leader, says scientists keep improving the computer software that understands brain signals and turns them into simple orders. “The practical possibilities that BCI technology offers to disabled people can be divided into two kinds: communication, and controlling the machine. One example is this wheelchair.”

He says his team has set two goals. One is testing with real patients, so as to prove that this is a technology they can benefit from. And the other is to ensure that they can use the technology over long periods of time.
