These signals were transmitted to a computer via a cable and translated by algorithms into point-and-click commands guiding a cursor to characters on an onscreen keyboard.
“These high-performing BCI algorithms’ use in human clinical trials demonstrates the potential for this class of technology to restore communication to people with paralysis,” said Nuyujukian.
Millions of people with paralysis reside in the United States.
The investigational system used in the study, an intracortical brain-computer interface called the Brain Gate Neural Interface System*, represents the newest generation of BCIs.
Previous generations picked up signals first via electrical leads placed on the scalp, then by being surgically positioned at the brain’s surface beneath the skull.
“We’re achieving communication rates that many people with arm and hand paralysis would find useful.
