This is the text (if you need help).
A man who can't move his hands used his thoughts to write. He is paralyzed from the neck down. He has a spinal cord injury. Scientists call him T5. They put two sensors into T5's brain so he could use his mind to write. The scientists call this "mindwriting". T5 can write 18 words per minute.
Mindwriting is simple, but it uses a lot of technology. Scientists asked T5 to imagine writing with a pen. The two sensors turned his brain activity into text on a screen. A researcher hopes mindwriting will help paralyzed people and people who cannot speak to write. Mindwriting might help us to write at the speed of thought.
