Casey Harrell, an ALS patient, has regained the ability to speak clearly thanks to a groundbreaking brain-computer interface. Scientists have implanted 256 electrodes in his brain, creating a neuroprosthesis that functions as a text-to-speech brain implant. This innovative technology allows for more than 97% accuracy in decoding Harrell's intended speech, marking a significant advancement for patients with impaired speech due to conditions like amyotrophic lateral sclerosis (ALS) and motor neuron disease (MND). The development is akin to a prosthetic for the brain.
