Remarkable leaps in brain–computer interface technology that could restore more naturalistic communication to people living with paralysis have been described in two recent papers in Nature. Both experimental systems have shown the ability to decode brain activity into speech faster, more accurately and with a larger vocabulary than existing alternatives. […]
