　　[2016·河南重点中学联考]A paralysed man has walked again thanks toP1 an electronic device—a special brain cap, which connected his brain signals to electrodes attachedW1 to his legs. The 26yearold man was able to control his legs and cover almost four metres using his own muscle power. This is believed to be the first time that anyone has used their own muscles, controlled on their ownP2.

　　The man, who has not been named, lost the power of both legs after his spinal cord was completely severed in a motorcycle accident five years ago. His brain was still able to generate the thoughts needed to move his legs and his muscles were healthy, but the damage to his spine stopped the brain's signals from reaching his muscles. To get round this, the man wore a cap connected with electrodes that capturedW2 his brain activity. This information was sent wirelessly to a computer and decoded before being transmitted to electrodes around his knees. These stimulatedW3 his muscles, allowing him to swing his legs.
