USA - Brain Chip Allows Paralyzed Man to Write

K. Farmer

Paralyzed from the neck down, the man stares intently at a screen. As he imagines handwriting letters, they appear before him as typed text thanks to a new brain implant.

The 65-year-old is “typing” at a speed similar to his peers tapping on a smartphone, using a device that could one day help paralyzed people communicate quickly and easily.

The research could benefit people suffering spinal cord injuries, strokes or motor neurone disease, said Frank Willett, a research scientist at Stanford University and lead author of the study published in the journal Nature.

“Imagine if you could only move your eyes up and down but couldn’t move anything else—a device like this could enable you to type your thoughts at speeds that are comparable to that of normal handwriting or typing on a smartphone,” he told AFP.

The researchers found that handwriting generates distinctive brain activity that proved easier for an implant to detect and a computer program to interpret and translate into text.

The research involved a man nicknamed T5 who was paralyzed from the neck down after a spinal cord injury in 2007.

He was fitted with two aspirin-sized brain-computer interface (BCI) chips on the left side of his brain that could detect neurons firing in the motor cortex that governs hand movement.

Sensors transmitted the signals to a computer for translation by an artificial intelligence algorithm into typed text.

Over time, T5 was able to produce 90 characters or about 18 words a minute when copying sentences, and around 74 characters or 15 words a minute when replying to questions., 12 May 2021


Nearly every day, we read something in the news about medical advancements due to cutting edge technology. It is incredible that this machine can help a fully paralyzed man “write” simply by imagining handwritten letters. 

However, there is also something sinister that one can imagine arising from technology like this: “And he had power to give life unto the image of the beast, that the image of the beast should both speak, and cause that as many as would not worship the image of the beast should be killed” (Revelation 13:15).
