03:40 PM EDT, 05/09/2024 (MT Newswires) -- Elon Musk-owned Neuralink said its human brain implant faced a period of reduction in transmission of data, weeks after it was surgically attached to its first recipient, Noland Arbaugh.

Arbaugh was able to control his laptop using a cursor with his mind, following the implantation in January.

But later, multiple threads of the implant "retracted from the brain" that resulted in "a net decrease in the number of effective electrodes," Neuralink said in a blogpost. This resulted in a reduction in bits per second, or BPS, which measures the speed and accuracy of cursor control.

The company modified the algorithm to be more sensitive to signals, "improved the techniques to translate these signals into cursor movements, and enhanced the user interface."

"These refinements produced a rapid and sustained improvement in BPS, that has now superseded Noland's initial performance," Neuralink said.
