85% of Neuralink implant wires are already detached, says patient
In an interview, Noland Arbaugh says the company wanted to avoid further surgery.
An estimated 85-percent of Neuralink’s brain-computer interface(BCI) implant threads connected to the first human patient ’s motor cortex are now completely detached and his brain has shifted inside his skull up to three times what the company expected, volunteer Noland Arbaugh told The Wall Street Journal on Monday. In an update quietly published earlier this month, the company says it ultimately determined that the malfunction had reduced the implant’s bits-per-second (BPS) rate, a measure of the BCI’s performance speed and accuracy. “These refinements produced a rapid and sustained improvement in BPS, that has now superseded Noland’s initial performance,” Neuralink wrote next to a data graph illustration with no additional citation.
