摘要
As reported in July 2021 in The New England Journal of Medicine,a neural implant helped a paralyzed man speak his first compre-hensible words in 18 years:“My family is outside”[1,2].The achievement—albeit in a single patient,nicknamed Pancho,who as a 20-year-old in 2003 suffered a severe stroke following a hor-rific car crash—highlights recent progress in engineering brain–computer interfaces(BCIs).The algorithms that control the array of electrodes placed onto the speech areas of Pancho’s brain and translate his neural activity into words were developed by researchers at the University of California,San Francisco(UCSF).The team hopes their work could one day restore the ability to communicate to the thousands of people each year that lose the capacity to speak due to stroke,disease,or injury.
