I wonder if they've done anything to slow the rate of fiber retraction. I recall the first one lost most of its connections very quickly.

- lallysingh 2y ago> Thread Retraction Mitigations > With our first participant, Noland, we observed a degree of thread retraction that temporarily reduced his BCI performance. The threads have stabilized, and the performance of Noland’s Link has since recovered — more than doubling the prior world record for BCI cursor control. > To reduce the probability of thread retraction in our second participant, we implemented a number of mitigations, including reducing brain motion during the surgery and reducing the gap between the implant and the surface of the brain. We discussed these measures in greater detail in our live update prior to our second participant’s surgery. > Promisingly, we have observed no thread retraction in our second participant.
