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（计算机的控制杆） as she watched a horizontal（水平的） series of lights on a display panel（显示屏）. 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.control panel.

1.Belle would be fed some fruit juice if she
A.moved the joystick according to what she heard
B.watched lights on a display panel.C.sat quietly in a special chair.
D.moved the joystick to the side of the light.
Belle wore a cap glued to her head.Under it were four plastic connectors（连接器）, which fed （释放出） arrays of microwires （－each wire finer than the finest sewing thread－） into different regions of Belles motor cortex（运动神经皮层） , the brain tissue that plans movements and sends instructions.Each of the 100 microwires lay beside a single motor neuron.When a neuron produced an electrical discharge（电流）, the adjacent microwire would capture the current and send it up through a small wiring bundle（线捆） that ran from Belles cap to a box of electronics on a table next to the booth.The box, in turn, was linked to two computers, one next door and the other half a country away.
