Neuralink’s first implant partly detached from patient’s brain

Some of the threads connecting the chip to the brain began to retract. The Elon Musk-owned company did not explain why

Neuralink's first attempt at implanting its chip in a human being's skull hit an unexpected setback after the device began to detach from the patient's brain, the company revealed on Wednesday.

The patient, Noland Arbaugh, underwent surgery in February to attach a Neuralink chip to his brain, but the device's functionality began to decrease within the month after his implant. Some of the device's threads, which connect the miniature computer to the brain, had begun to retract. Neuralink did not disclose why the device partly retracted from Arbaugh's brain, but stated in a blogpost that its engineers had refined the implant and restored functionality.
