WEDNESDAY, May 29, 2024 (HealthDay News) -- A bilingual brain implant has allowed a stroke survivor to communicate in both Spanish and English, scientists report. Turning to an AI method known as a neural network, researchers trained the patient's implant to decode words based on the brain activity produced when he tried to articulate those words, and then display those words and sentences on a screen. This method allows the brain implant to process data in a way that is similar to the human brain.
Scientists at the University of California, San Francisco's Center for Neural Engineering and Prostheses have labored for years to design a decoding system that could turn the patient's brain activity into sentences in both languages. In a report published May 20 in the journal Nature Biomedical Engineering , the scientists share the details of their effort. “This new study is an important contribution for the emerging field of speech-restoration neuroprostheses,” Sergey Stavisky , a neuroscientist at the University of California, Davis, who was not involved in the study, said in a journal news release .
Even though the study included only one patient and more research is needed, “there’s every reason to think that this strategy will work with higher accuracy in the future when combined with other recent advances,” Stavisky added. The saga of the bilingual brain implant first began five years ago. At age 20, a man identified as Pancho became severely paralyzed after havin.
