    Hehe I found it:
    “They’re not particularly cutting through it (the blood brain barrier). The BBB exists as three layers (going from inside vessel lumen to brain): endothelial cells line the vessel wall, a basement membrane, and processes from astrocytes. Changes in permeability in any of these makes it more or less difficult to get from vessel to brain tissue. Almost identical in the kidney. Their surgical robot uses computer vision to avoid cortical vessels during vertical insertion of probes, instead going in between glial cells and neurons, with some of those cells being penetrated most likely (which is kind of benign to my knowledge). If that robot nicks a vessel wall, however, then we get a deeply sophisticated acute inflammation cascade, as well as blood leaking into the neuropil. Hence the computer vision and tracking of heart beat fluctuations in the brain location. Keeping that robot sterile and the devices sterile will also be key in preventing infection. However, as a first start at keeping implantation a minimally invasive as possible, and in under two years, what they have is pretty bloody impressive. Keep up the inspiring work, Neuralink!”

    So inspiring you guys, might as well be Theranos 2.0 considering the experiment in the report did not use the all-knowing and all-seeing surgeon robot.
