The world's first patch that gives words to thought passes the test |
SAN FRANCISCO: A brain-transplant has been successfully tested, and a speech-impaired person has since performed 50 thought-provoking words.
This brain transplant works under a neural network and helps with brain movements (patterns) and movement of the throat wires.
After ten years of working day and night, the University of California, San Francisco (UCSF) has, for the first time in the world, gifted a voice to a deaf person with a brain-powered electronic chip.
The experiment tested a person with a stroke in their 30s. After installing it, the patient can put his thoughts into words and can now complete 50 words. For this, the patient only had to utter the words with thinking and those words were uttered through the speaker in an artificial (machine) voice.
Highly optimistic technology will be of great benefit to those who stop speaking due to illness or accident. Previously, devices with disabilities required a person with a disability to move a computer cursor over specific words, but this new system reads the part of the brain where words and sounds are generated. Because such people forget their words but thoughts and words keep arising in their minds.
Following the first success, it is now being tested on 28 more patients. Under normal circumstances we speak 150 to 200 words per minute but thanks to this new system he can now speak 30 words per minute, while the total vocabulary is 50 words which can be increased.
Details of this important study have been published in the New England Journal of Medicine. If the patch is examined, it is surgically implanted in the brain. Custom neural network models are then tested at the software level. In the next step, the human signal was inserted into this model. This system compares the words that are born in the brain and its signals and utters the key words in it and this process continues without any delay.
The doctors asked the patient, "Would you like some water?" So thinking about it, he replied, "No, I'm not thirsty."
Scientists were delighted to hear such answers. It currently processes 18 words per minute but has an accuracy rate of only 75% which can be improved.
