　　Controlling Robots with the Mind

　　Belle, our tiny monkey, was seated in her special chair inside a chamber at our Duke University lab. Her right hand grasped a joystick as she watched a horizontal series of lights on a display panel. She knew that if a light suddenly shone and she moved the joystick left or right to correspond to its position, she would be sent a drop of fruit juice into her mouth.

　　After months of hard work, we were about to test the idea that we could reliably

　　Finally the moment came. We randomly switched on lights in front of Belle, and she immediately moved her joystick back and forth to correspond to them. Our robot arm moved similarly to Belles real arm. So did Sriniwlsans. Belle and the robots moved in synchrony , like dancers choreographed by the electrical impulses sparking in Belles mind.

　　41 Belle would be fed some fruit juice if she

　　B moved the joystick to the side of the light.

　　D watched lights on a display panel.

　　A a plastic box next door.

　　C a box of electronics in the booth.

　　43 Which of the following is NOT true of the robot built by Srinivasan?

　　B It converted the electrical patterns into instructions for the other robot.

　　D It could perform the same function as Belle did.

　　A Belle responded to the robots successfully.

　　C Belle and the robots responded to the lights at the same time.

　　45 The short-term goal of the research is to help a person

　　B who can operate a wheelchair but not a robotic limb.

　　D who is unable to move but whose motor cortex is not damaged
