before i get 'busted', i don't 'discount' the recent stem cell findings.
if robust enough, for instance, they'd constitute an excellent contribution
within the physical dynamics underpinning extremely-long-term, and
relatively-enduring, "inversion" [big-time "changing of one's mind" (if it's
via stem cell proliferation, =literally= :-)] which [such fundamental
"inversion"], with respect to Seeing beyond 'blindly'-automated TD
E/I-minimization, has been a major focus of the stuff i've posted since
coming back online.
in themselves, the stem cells are insufficient, though. they'd have to be
'interposed' within the rest of what's discussed in AoK. problems like the
dynamics of their distribution within the brain are relatively-easy. all the
necessary directional information exists within the one Internal Frame of
Reference [IFR] Geometry. all the stem cells'd have to do is 'swim' in
accord with the ionic 'current' that's in TD E/I-minimization.]
it seems to me that this one "inversion" thing is promising re. stem cells.
of course, the other more-obvious thing is fault-tolerance maintenance and
'repair', including TD E/I-minimization "whoop-sa-daiseys" [but these are
mini-"inversions"].
i expect that there's already enough in the Literature, but i haven't
gotten-into it yet. probably won't [unless i can find employment]. so i
encourage others to go-for-it.
