In principle they could have pulled out slightly, if there’s jostling and tiny movements in skull then you’d expect them to work loose over time if they’re not securely anchored
Comment on Neuralink's first in-human brain implant has experienced a problem, company says
KISSmyOSFeddit@lemmy.world 7 months ago
I find the wording weird: The neuralink’s threads have retracted from the brain.
The threads can’t move or disconnect on their own. Neither can brain cells. All that can be measured is a loss of connection.
The far more reasonable explanation is that the brain cells at the connection point have died.

The patient was a paraplegic. I’m not sure how much they’d be capable of moving enough to dislodge the in-skull writing.
Zron@lemmy.world 7 months ago
Paraplegics still need to move or be moved.
If they don’t rotate into different laying or sitting positions, they’ll develop bed sores they can’t even feel, which can be extremely dangerous. They also still need to move their limbs to avoid blood clots.
All this shows is that Neurolink isn’t ready for one reason or another. Either the wires are so fragile they become dislodged or broken by gentle movements during physiotherapy, or the surgery damaged the brain. Either way this is a major issue with the technology. No way are they going to be putting robot limbs on people if the chip that can control them is this unreliable.

Let me just go ahead and remind you that the cyber truck exists.

In one of the interview with Nolan he says he has full body spasms when he sits in the chair and those spasms take him out of position from being able to use the mouth stick controller. With neuralink he doesn’t need intervention by someone else post spasms to continue.

i would assume the brain itself has retracted from neuralink.
I.e. The brain doesnt want fuck shit to do with it.

If im not 100% off basis here, “Electric meat is still meat, and we just stabbed it with little tiny forks”

I seem to recall that scarring around the electrodes, which eventually causes them to stop functioning, is a known failure mode of older experiments along similar lines. It’s one of the reasons I didn’t hold out much hope for this iteration.
I just hope the patient doesn’t take any long-term damage from the implant.

If the moneys are anything to go on, that dudes in for an extremely painful death.
