Scientists have developed a computerized device that can read the brain waves of a paralyzed person and translate them into more words than ever before. Earlier in 2021, researchers at the University of California tested a neuroprosthetic device on a paralyzed person who was unable to speak, understand and read.

Neuroprosthetic device

Experts said that the 'neuroprosthetic device' was able to translate 26 words of the paralyzed person, but one difficulty is that if a person utters the English word 'cat' meaning cat, the computer will call him 'cat'. will say 'Charlie Alpha Tango' instead. However, now the American experts have further improved this technology, experts claim that the said device can translate more words per minute than before and will work at a faster speed than before.

According to the report of the foreign news agency "AFP", the device was tested by the University of California researchers on a paralyzed person who was unable to speak, understand and read. Pat Bennett, a 68-year-old woman with motor neuron disease, hopes the technology will help the paralyzed person reconnect with the world.

Technology was attached to the mind of a paralyzed woman

According to experts, when this technology was attached to the mind of a paralyzed woman during the experiment, the device translated the words that came to the mind of the said woman. In March of last year, Stanford University scientists implanted 4 small pieces of silicon with 64 small electrodes in Pete Bennett's brain, the journal Nature reported.

Electrodes were very small

These electrodes were very small and are used in the field of neuroscience to study the brain. These electrodes were placed within only 1.5 mm of the outer layer of the brain, the gray matter, which originates from these parts of the brain. Record the electrical signals that occur and help us speak. As 68-year-old Pat Bennett tries to speak words with her tongue, an algorithm decodes the information coming out of her brain. The system needs to know what to do says Dr. Frank Willett, co-author of the journal. is trained to know which words should come before other words.' Pat Bennett's brainwave-to-word software was tested for 4 months. The software used the woman's brainwaves to translate 62 words per minute on the screen, nearly 3 times faster than previous technology.

Dr. Frank Willett

Experts say that about 160 words are spoken per minute during a normal conversation, but so far, no technology has been developed that can be used by paralyzed people in their daily lives. There were also mistakes in them, he said that one in every 10 words was wrong. However, experts say that the errors of the said technology have decreased by 10 percent compared to the previous technology. Dr. Frank Willett says that There is a major advance towards rapid communication recovery for people with paralysis.
