Experimental brain transplant helps stroke again

The scholars have developed a The device is able to translate ideas About words in spoken words in real time. Although he is still in an experimental stage, they hope so Brain interface It can one day help give a voice to those who cannot communicate for speech.

A new study describes the device tests in Woman 47 -years with Tetraplejia Those who were unable to speak for 18 years after being stroke. Doctors planted it in the brain during the surgical intervention in the framework of A. Clinical. The device “converts its attempt to speak in it Fellow phrases“Jobala Anumsheibi, the joint author of the study, published in the” Nature Neuroscience “magazine.

Other facades of the brain (BCI) for speech, they usually have a simple delay between thought and Computerized verbal. According to researchers, these delays can boycott the natural flow of conversation and cause the failure of communication and frustration.

This “a Significant progress Jonathan Bomberg, in the study in the field of Kansas (USA), has not participated in the study “in our field.”

How works brain transplantation

California team scored Brain activity for women By electrodes while pronouncing phrases in silence in his brain. Scientists used a Mixture They built the woman’s voice before they injured themselves to create the voice that she had pronounced. Then they trained a model Artificial Intelligence (AI) This translates nervous activity into sound units.

Amiancapalli, de la California University in Berkeley (USA), shows that it is working similar to the systems used Copy meetings Or real -time phone calls.

Cultivation It is placed in the midst of the brain discourse to listen, and the signals are translated into Speech fragments that make up phrases. According to Anumanchipalli, it is the “continuous flow approach”, where each part of a speech is sent from 80 milliliters (approximately average clip) to a registered. “The phrase is not expected to end,” explains Anumsheibi. “He treats her while flying.”

According to Labberg, Decipher Even quickly you can follow the pace of natural speech. He added that the use of sound samples “means great progress in the natural speech.”

Although the work was partially funded by the US National Institutes of the United States, Anumanchipalli said it was not affected by Recent research discounts From the National Institutes of Health. He said it is necessary to continue the investigation before technology is ready for generalized use, but with “continuous investments”, it may be available to patients a decade ago.
