Neuralink faced a setback when wires from its brain chip retracted, causing malfunctions in its first human patient, as per a recent report.
Early Awareness of Risks
Before inserting the implant in its first human patient in January, Neuralink was already cognizant of the potential risks associated with the brain-chip implant malfunctioning, according to Reuters. The patient, Noland Arbaugh, experienced issues shortly after the procedure when some of the device's wires detached from his brain.
Pre-existing Knowledge
Reports indicate that Neuralink had conducted tests on animals, wherein they discovered that the wires could retract from the device. Despite this knowledge, the company proceeded with the implant, believing the risk to be minimal.
Experimental Procedures
Prior to gaining approval for human trials from the US Food and Drug Administration last May, Neuralink conducted experiments on animals, including monkeys. The implant, known as "The Link," features over 1,000 electrodes and at least 64 thin wires or "threads," some of which dislodged from their intended positions.
Functional Impact
The displacement of wires resulted in reduced effectiveness of the implant, affecting Arbaugh's ability to control a computer cursor. Despite initial considerations to remove the implant, Neuralink made adjustments to enhance its functionality.
Positive Outcomes
Arbaugh, who was paralyzed below the shoulders due to a diving accident in 2016, regained some independence post-implantation. He can now operate his laptop, browse the web, and play computer games without constant assistance.
Future Plans
Neuralink aims to implant 10 devices in additional human patients by the year-end. The company is focused on advancing neurotechnology to empower individuals with paralysis to control devices using their thoughts.
Business Insider's request for comment from Neuralink remains unanswered as of now.
