He could even talk as he watched the vehicle and guided it with his thoughts.“our, brain has bul

3、lions of nerve ceils. These send signals through the spinal cord （脊髓）to the muscles to give us the ability to move. 3ut spinal cord injuries or other conditions can prevent these weak electrical signals from reaching the muscles, n Tavella says. Our system allows disabled people to communicate with

4、external world and al so to control devices.”The researchers designed a special cap for the user. This head cover picks up the signals from the scalp（頭皮）and sends them to a computer. The computer interprets the signals and commands the motorized whe.elchair. The wheelchair also has two cameras that

5、identify objects in its path.
