Scientists have created a neuro interface that turns brain waves into words
A group of scientists from the University of California at San Francisco (UCSF) has developed a neuro interface for decoding commands sent by the brain to the speech tract. The technology allowed a paralyzed patient to communicate with anartria for about 15 years, the study says.
Scientists noted that at the beginning of the study, the team faced the lack of data on patterns explaining the connection of brain activity at least with the simplest components of speech – phonemes and syllables.
Therefore, they used the information provided by volunteers from the UCSF epilepsy center. There, people before surgery surgically apply electrodes to the surface of the cerebral cortex to create a map of areas involved during seizures.
Many of these patients are involved in research experiments using the recordings of their brain waves. Therefore, experts asked volunteers to allow to study the patterns of neural activity during communication.
They recorded changes in the brain waves of respondents when pronouncing simple words and sounds and tracked the movements of their tongue and mouth.
Sometimes scientists painted their faces to patients in order to extract kinematic gestures using a computer vision system. They also used an ultrasonic apparatus under the jaw to model language movements in the mouth.
Then the team compared neural patterns with muscle contraction. According to experts, there is a map of representations that controls various parts of the speech tract. They also found that during easy communication, various areas of the brain work together and coordinated.
The UCSF team has already attracted two volunteers to test https://gagarin.news/news/anthony-hopkins-is-interested-in-buying-collectible-nf-ts/ the system. In the future, they plan to increase the number of participants in the experiment and allow them to communicate at a speed of 100 words per minute.
Recall that in May, the American startup Synchron launched clinical tests of the Stentrode neuro interface designed to help paralyzed patients.
In January, scientists developed an eye implant based on AI, which returned his almost blind woman vision.
In August 2021, Synchron received permission from US food and medicines for testing neuro interfaces in humans.
