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…
At-home brain implant gives man with motor neuron disease his daily life back
(Nature) – The device has helped a man with motor neuron disease communicate and control his computer for nearly two years. The brain–computer interface (BCI) has given 48-year-old study participant Casey Harrell, who was diagnosed with a type of motor neuron disease called amyotrophic lateral sclerosis six years ago, the ability to communicate with an average speed of 56 words per minute. It translates neural activity into text that appears on …
