Brain Implant Lets Man With Severe Paralysis Speak in His Own Voice Again
A man with severe paralysis, who can no longer move almost any part of his body, can now 'speak' on his own terms, using an experimental brain implant. His family can finally hear his voice again, as a digital version reads his thoughts aloud. Casey Harrell has an advanced form of amyotrophic lateral sclerosis (ALS), which makes his natural speech very difficult for others to understand. But he has a lot to say when given the opportunity. For ne…
Brain Chip Implant Enables Paralyzed ALS Patient To Speak And Work Again
Recent breakthroughs in neural engineering have bridged the gap between brain-computer interfaces and practical tools for daily life. A long-term study published in Nature reveals that a 47-year-old man paralyzed by amyotrophic lateral sclerosis (ALS) has successfully used an implanted neural device to communicate independently at home and
According to researchers at the University of California in Davis, an implanted brain-computer interface allowed Casey Harrell, a patient with ALS (amyotrophic lateral sclerosis) unable to speak, synthesize phrases from brain activity with an accuracy of 99% in controlled tests and about 92% in daily life. Reports indicate that the system has been used at home since 2023, helping the latter to communicate naturally, to control the effects of the…
A patient with ALA and severe paralysis who has been living with a brain implant since 2023 shows that this system reads the neuronal activity associated with the attempt to speak and that it also does so in a stable, autonomous way and in a domestic environment, without the presence of researchers.
Amyotrophic lateral sclerosis (ALS) is a disease in which motor neurons that control muscle movement are damaged, causing the muscles in the limbs, throat, and tongue to gradually waste away and become immobile, making it difficult to move the body and speak. However, it has been reported that a man suffering from ALS who had lost the ability to speak properly has been able to communicate at will thanks to a brain-computer interface (BCI) implan…
