I guess threads can't surround the brain
from the opening..........
nevermind on this.
maybe through the sulci and fissures (crevices)
but that would differ from person to person
and its navigation would be limited
even if it can.
your team would know better mr Musk.
but the idea for permanent access to the
brain, to affect it at will, by whichever method....
that is better than it would be
just neuralink itself.
Maybe a pre-MRI scan,
and seeing the best pathway for the person.
and allocating the entrance point
customized for that person.
other than the neuralink.
but that is far more invasive,
and i don't think people would find it worthy.
