In a new study published Tuesday in the journal Nature Communications, Swiss and German researchers helped a 34-year-old man with severe ALS to communicate through a brain-computer interface (BCI) implanted in his brain
For hundreds of thousands of people living across the globe, communication isn’t as straightforward as moving your mouth or raising a hand. In the U.S.,amyotrophic lateral sclerosis—better known as ALS or Lou Gehrig’s disease. It’s a terrifying and incurable disease that progressively robs affected individuals of their ability to move, interact, and communicate.
, Swiss and German researchers helped a 34-year-old man with severe ALS to communicate through a brain-computer interface implanted in his brain. This new approach aims to revolutionize communication devices for patients with ALS and potentially other neurological disorders that severely impair speech and other movements.
The new ALS implant uses electrodes to pick up brain signals that are fired. While being shown in real-time the spikes of his brain activity, the 34-year-old study participant was asked to mentally match sound tones with each other. The new BCI system learned how to detect whether the participant was saying “yes” or “no” based solely on his brain activity.
Even the authors of this latest study have been in hot water over previous BCI trials. In September 2019, the German Research Foundation charged co-authors Niels Birbaumer and Ujwal Chaudhary with, citing that the pair failed to “film patient examinations in full, did not appropriately show details of their analyses in the papers and made false statements,” and in not doing so, had failed in the protective responsibility incumbent upon scientists when involving serious ill study participants.
