Neuralink to implant 2nd human with brain chip as 85% of threads retract in 1st

Algorithm tweaks made up for the loss, and Neuralink thinks it has fix for next patient.

Only about 15 percent of the electrode-bearing threads implanted in the brain of Neuralink's first human brain-chip patient continue to work properly, according to a report from The Wall Street Journal. The adjustments were effective enough to regain and then exceed performance on at least one metric—the bits-per-second (BPS) rate used to measure how quickly and accurately a patient with an implant can control a computer cursor. Neuralink, owned by controversial billionaire Elon Musk, believes it can prevent thread movement in the next patient by simply implanting the fine wires deeper into brain tissue.
