It's as Drs. Norman and Kirkcaldie
have discussed.

In the view I hold, though, there's
a single "rule" that I've never seen
violated, from gross Neuroanatomy
to sub-ionic dynamics.

Everything in a 'normal', orgaincally-
intact nervous system is mapped as
a single "multi-Mobius-ed Klein bottle".

[For those who have it, this is the
"spedial topological homeomorphism"
that's discussed in AoK.]

"multi-Mobius-ed": Like a bunch of
Mobius strips, intermapped, still having
only a single surface.

This mapping is what facilitates handling
of the problem of "being on the inside,
looking out", which is 'just' a big Dir-
ectionality-inversion problem.

And, when one looks at the gross
Neuroanatomy, one can literally see
this "multi-Mobius-ed Klein bottle"
in the great decussations, commisures,
and that it can only extend "all the way
down".

The "can only"-ness is visible in the
way that the great decussations are
ordered with respect to the cerebellum,
the outputs of which are entirely-inhib-
itory.

So the neural Topology =must= be
evrywhere-ordered to function in
accord with the easily-visible [veri-
fied] action of the cerebellum.

If such were not the case, then, to
the degree that it is not, the cerebellum
would be rendered non-functional,
which would be readily-apparent in
behavioral manifestations.

[Yes, there is a =lot= more in the
analysis that's been done, but the
above is all that's necessary to
Prove everything, at all scales.]

"That's my position, and I'm stickin'
to it. :-]

Private note:

=Finally!=, "a Round TUIT" :-]

Cheers, Drs. Norman and Kirkcaldie,
