TL;DR
A stroke can leave a person's brain still forming the intention to move while the arm it once commanded barely answers. Neuralink, whose implant already lets people paralyzed by spinal cord injury or ALS steer a computer cursor by thought, now has a second U.S. trial on the books, and this one is for stroke survivors. The record lists up to 10 adults whose dominant arm was weakened by a stroke at least a year earlier, with an estimated start this month; that detail comes from a secondary report, because the registry page itself could not be opened. Strokes are far more common than spinal injuries, which makes stroke survivors the likely first large group a brain implant could serve. The same week, a new New York institute launched to build brain interfaces, starting with helping blind people see again.
