Most-often most of the neural damage is
a 'temporary' consequence of abnormal
physical displacements 'within' the neur-
al network. Such displacements alter the
'normal' neural topology so that 'normal'
neural-activation coincidences do not oc-
cur [which constitutes a TD E/I(up) condi-
tion.]

The neural tissue has some built-in re-
silience which tends to return the neur-
al network to a somewhat 'normal' con-
dition ['normal' topology] if the forces
that imposed the injury did not sever
anything.

Most "concussions" are like this, although
usually more than just the brain stem is
involved.

These sorts of 'temporary' displacements
[temporary distortions of the neural to-
pology] occur because, in its living 'state',
the brain has the consistency of a semi-stiff
pudding [which consistency exists as a
physical substrate for the "hydraulic"
stuff that I've been discussing in other
threads here in b.n. "Concussions" are
abnormallly-rapid and large occurrences
of 'normal' hydraulic 'plasticity'. That is,
nervous systems are vulnerable to con-
cussive injury be-cause they use the ex-
tremely-less-violent versions of the 'same'
displacement dynamics during their 'norm-
al' functioning. The forces that injure ab-
use this innate stuff that's fundamental
within all of nervous system function.]

It's probable that all such 'temporary'
displacements leave behind at least
minor permanent injury, and that these
scraps of the 'discrete' trauma occur-
rences accumulate with repeated oc-
currences of such violently-forced 'temp-
orary' displacements.
