Man with ALS uses brain implant to speak

Casey Harrell, who has ALS and is paralyzed, has become the first "power user" of a brain-computer interface (BCI). He has had electrodes implanted in his brain for nearly three years, enabling him to "speak" sentences. Harrell has dedicated thousands of hours to using this technology since 2023, demonstrating significant progress in communication for individuals with severe motor impairments. This advancement highlights the potential of BCIs to restore communication abilities and improve the quality of life for those affected by conditions like ALS.
