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 (操纵杆) 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.
Belle wore a cap glued to her head. Under it were four plastic connectors, which fed arrays of microwires—each wire finer than the finest sewing thread—into different regions of Belle’s motor cortex (脑皮层), the brain tissue that plans movements and sends instructions. Each of the 100 microwires lay beside a single motor neuron (神经元). When a neuron produced an electrical discharge, the adjacent microwire would capture the current and send it up through a small wiring bundle that ran from Belle’s c
A. grasped the joystick
B. moved the joystick to the side of the light
C. sat quietly in a special chair
D. watched lights on a display panel

Small robots designed by University of Nebraska researchers may allow doctors on Earth to help perform surgery on patients in space.
The tiny, wheeled robots, (1) are about 3 inches tall and as wide as a lipstick case, can be slipped into small incisions (切口) and computer-controlled by surgeons in different locations. Some robots are equipped (2) cameras and lights and can send images back to surgeons and others have surgical tools attached that can be (3) remotely.
"We think this is going to (4) open surgery," Dr. Dmitry Oleynikov said at a news conference. Oleynikov is a (5) in computer-assisted surgery at the University of Nebraska Medical Center in Omaha.
Officials hope that NASA will teach (6) to use the robots soon enough so that surgeries could one day be performed in space.
On earth, the surgeons could control the robots the
