The work-encoding of information is hierarchical along a structural
continuum that runs from single ions to the whole nervous system.
For instance, the work a "gate" performs communicates via correlated
relative metabolic demands from the gate to other organelles within
the cell, demanding such and such performance from them, which,
through the correlated functioning of the organelles, communicates
further, and so forth, up to the nervous system as a whole, driving
macroscopic action [performing macroscopic work].
Throughout, one thing integrates everything - work with respect to
WDB2T - throughout, everything is 'just' TD E/I-minimization that
'senses' WDB2T, and which by-produces 'volition', cognition, affect
and behavior accordingly.
The main thing that I've been discussing all along is the way that,
because the way nervous systems process information has not been
generally comprehended, nervous systems 'blindly' and automatically
treat experientially-driven TD E/I-minimization as if it constitutes
Truth when all it is is experientially-driven TD E/I-minimization
that occurs with respect to collective behavioral inertia that exists
within the experiential environment.
It's important to get this straight because the absence of
understanding with respect to it leads to folks Slaughtering one
another for 'reasons' that have no existence within any absolute
external experiential reality.
Folks are killing one another - or doing stuff like perverting The
Constitution of The United States of America to cling to
nineteenth-century, or more ancient, stuff that Ravages others, etc.,
etc., etc. - ad infinitum within Human interactive dynamics - for no
reason than that their nervous systems are acquiescing to
'blindly'-automated TD E/I-minimization.
All of this Slaughter can be transcended through the understanding of
how nervous systems process information.
Looking to such understanding is the only practical method because
the work entailed includes folks going back therough their branches
of Civilization and recognizing how and why the 'passions' that
induce them to 'hate' arise, not with respect to this or that 'rule'
but solely with respect to their intergenerationally-converged-upon,
and intergenerationally-handed-down 'consensus'.
The 'program' entails replacing happenstance experiential convergence
with Reasoned convergence.
Why an understanding of how nervous systems work is Necessary is
because it's necessary to understand how affective alignment arises
within nervous systems in a 'blindly'-automated way with respect to
Nothing else can expose the illogic inherent in the 'passions' that
Nothing else can displace 'passion' with Reason.
The 'walls' that fracture Humanity dis-integrate into nothingness
when one understands how it is that 'passion' comes to be correlated
with mere experience.
Why it matters - why the same-old historical approach is no nonger
workable is that populations-wide TD E/I is net-monotonically
augmenting because weapons of mass destruction are proliferating and
because modern means of communication are imposing 'unfamiliar' [TD
E/I(up)-inducing] stuff across what have, historically, constituted
the 'borders' of relatively-mutually-exclusive experience.
It's why understanding how nervous systems work matters, and why it's
worth doing the work inherent.
It's my Analysis that the Survival of Humanity depends upon this work
I wouldn't 'bother' folks if it weren't so.

| =Every= ionic conductance, including charged macromolecules, enters

| sees only K+? That Na++ sees only Na++? Do you think K conductance
| can exist without Na conductance?
| All ionic "channels" respond to the net ionic "charge" - of course
| with respect to their specifically-'engineered' "gate" correlates,
| but there's a whole 'world' in-there that enters into the
| determination of the specifics.
| For instance, neural glia act as K+ "electrodes", redistributing K+
| concentration gradients in accord with ongoing neural activity.
| Saying this or that is that or this doesn't make tthis or that that
| or this.
| One has to get in-there and follow the ionic conductances before
| can discern =anything= with respect to a k+, or other ionic
| in vivo, 'resting' potentials, etc., vary[everything "ionic"
| in accord with the ionic background.
| If one wants to have coctails at conferences, one needn't follow
| ionic conductances, but if one wants to comprehend CNS function,
| must do so.
| No "ideal cases" - no "absolutes" - everything's relative to the
| ongiong ionic conductances.
| Understand [all]?

| Obviously, you're not an "idiot". You;ve just read the books and
| out the most important thing - to think.
| NA++ same-old, same-old.
| Anything ionic, same-old, same-old.
| Of course, with respect to specifically-'engineered' "gates", etc.
| The quantity of work a gate must perform against the ionic
| encodes the 'state' from which learning-correlated microscopic
| trophic modifications gain their information-contents.
| Everything within nervous systems is rigorously-coupled to WDB2T.
| The work-encoding with respect to WDB2T is how information is
| cross-correlated, and retrieved within nervous systems.
| | Theres a "conseptualization" thats wrong. If I define something

| | X=2, now I know that X=2.
| But if your definition stands before you as a 'closed door' that
| prevents your seeing what's necessary to see, your "deinintion" is
| nothing more than a 'brick wall' that's worthy of nothing other
| being 'torn down'.
| What good is a "definition" that 'blinds' you?

| In vivo, no such thing as an "absolute refractory period" has any

| | The normal level of stimulation. The level at which
| | is would normal fire an AP at. The threshold of
| | activation. Call it whatever you want, if you
| | want to argue that there is no such thing, you're
| | going against what everybody bar you thinks.
| "What everybody thinks" is wrong, as above, because "everybody"
| doesn't get-in-there with the ionic conductances - as above.
| There's =nothing= 'static' within nervous systems. Everything is
| 'tuned' with respect to the ongoing conductances. This's where
| "intelligence" arises - in the quantities of work that stuff like
| "gates" ["punps", etc.] perform, the rigorous correlation to WDB2T
| becomes established - this's how nervous systems "know" what ever
| is that they [via TD E/I-minimization] converge upon "knowing". All
| information is work-encoded within nervous systems in this way.
| Everything within nervous systems is 'linked' together in terms of
| such work.
| The neural Topology establishes the substrate in which the
| work-distribution is "recognized" - from the ionic 'level' all the
| way up to effector-driving, with cognition in-between -
| is work-encoded.
| The easiest way to get an initial 'handle' on this is to study the
| motions of your hands as you are performing externally-relevant
| Calculate that work, then follow it back into your nervous system.
| Throughout, it's all the same stuff - calculating with respect to
| The calculations can be performed by nervous systems because WDB2T
| permeates physical reality in a way that is consistent.
| That is, there are local variations in WDB2T, but no matter the
| vairiance [within the bounds of what's survivable], nervous systems
| are able to 'sense' its 'meaning' in terms of the work that dealing
| with it entails.
| Is it freezing-cold outside? -> do the work necessary to find a
| more-favorable WDB2T energy-gradient [to find 'warmth'].
| Is it hot? -> do the opposite.
| It's all 'moving toward', or 'moving away from', with respect to
| external WDB2T.

| | I don't think the poster was interesting in
| | comprehending the nervous system as a
| | whole. He wanted to know how far a AP
| | travel during the absolute refractory period,
| | so I told him.
| I explained why I 'jumped' your post.
| The books are 'stepping-stones' upon which one can 'stand', but
| to see-further, not 'dictators'. And if they're left as the latter,
| then either the Author of the Reader has failed.
| The questioner was best-served by telling him where to go to start
| thinking, not what to think.
| That, and that you've been 'jumping' my posts as if you think I'm
| some sort of 'crack-pot', and that always gets my 'attention',
| or later.
| I mean no 'offense', but there's Truth on the line, and I 'move
| toward' Truth.
