Paragraph 1
A man who cannot move his
or hands has used his thoughts to write on a computer
. The man has been paralyzed from the
down for almost a decade. Scientists from Stanford University in the USA implanted two tiny
into the man's brain. The scientists gave this
two names - "brain-to-text" and "mindwriting". The man wants to remain
, so scientists have called him T5. He became paralyzed after suffering a spinal cord
ten years ago. The implants have allowed T5 to use his
to write. He can write 90 characters (about 18 words) per
. This is five words slower than the average person writing a
message on a smartphone.
