Scientists regenerate neurons that restore walking in mice after paralysis from spinal cord injury::In a new study in mice, a team of researchers from UCLA, the Swiss Federal Institute of Technology, and Harvard University have uncovered a crucial component for restoring functional activity after spinal cord injury. The neuroscientists have shown that re-growing specific neurons back to their natural target regions led to recovery, while random regrowth was not effective.
Their comment was in relation to Neuralink being in the news about killing monkeys, recently, not attributing OP’s news to him.
I know, I’m referring to a separate story that used an implant to wirelessly transmit the signal to the spinal cord. They were killing a bunch of cats and monkeys as well for their research. But they approached this responsibly and got a working prototype that helped a patient to walk again: https://www.bbc.com/news/science-environment-65689580
