UCSF researchers build bilingual AI brain implant that helps stroke survivor communicate in two languages

Scientists at UCSF have developed a groundbreaking brain implant using artificial intelligence to help a stroke survivor communicate in both Spanish and English. The implant turned the patient's brain activity into sentences, allowing him to participate in bilingual conversations and switch between languages. Dr. Edward Chang, a UCSF neurosurgeon and co-director of the Center for Neural Engineering and Prostheses, joined us on 'The Nine' to explain how it works, and discuss his team's findings.
