==== Conjectures on a Mechanism for Biological Memory: ====

Read each step. Don't don't jump to the end. The last part will begin to resonate with the beginning. :)

* All high negentropic structures necessarily have a long causality chain.

* Good examples of high negentropy are 1) Brains 2) Fungi 3) LLMs

* If the Block Universe (Eternalism) is true it means time is a bit of an illusion and the "past" sort of "coexists" with the present.

* Slices thru such a Block we'll call "Foliations".

* Quantum Mechanical Probabilities are waves thru spacetime that must be guided around prior collapsed events (i.e. particles which have existed on one Foliation)

* All Quantum Interactions leave an Entanglement between the cause/effect (one foliation to the next)

* Entanglement is a time-independent effect (unhindered by distances across spactime)

* If foliations are entangled then indirectly the entire causality chain of a high-negentropic structure is necessarily itself fully entangled

* A fully entangled path down a chain of foliations can support Quantum Probablity wave transmission (signal carrying) -- not matter waves, probability waves.

* The higher the negentropy the more 'structure' there is in the causality chain and thus the higher fidelity this Probability Wave signal will be.

* Any wave signal can experience what's called "Resonance", which is a well understood mathematically precise wave phenomena, and there is no wave phenomena what doesn't also exhibit it.

* Resonance means something 'distant' will automatically transmit energy (i.e. information) from a far away place purely thru wave effects. For example if you're an Opera Singer you can find a wine glass hidden in your house by singing it's pitch, and then listening, you'll hear it vibrating back at you.

* TYING IT TOGETHER: The thing that Brains and Fungi are doing, that we call "memory", are really just a resonance with their own past down that quantum mechanically interlinked and fully entangled causality chain. Memories are not "locally stored". They're stored in the foliation of the original experience which still exists in the Block Universe and can be "resonated with" (i.e. remembered) in what we think of as "in realtime". If you 'remember' something from 6 months ago, your "past brain" (on the opposite side of sun) which "still exists" is where your current brain is resonating with to pull up your current state (your memory of a past 'state').

* How do we get around the Speed of Light limitation? Because these are probability waves of entanglement that are resonating, not matter waves. People have speculated for decades that Consciousness might be Quantum Mechanical, and I'm finally explaining HOW it actually works. Entanglement has no limitations about how far the spacetime distance is. Entanglement is always instantaneous regardless of spacetime distance.

* EPILOGUE: Most mysteries about the brain are explained by this like: 1) Why DeJa Vu happens. 2) Why brains are 'pattern matching' machines. 4) Why complex patterns lead to recollections without you trying. 5) Why you'll remember something if you repeat it over and over. 6) How false memories can form. Even the repeated "loop" of this "effect" is what we call "stream of consciousness". One thing resonating with it's nearest match, going on endlessly. I can list 100s of examples. Once you realize memory is a resonance with past brain states everything falls into place regarding neuroscience, and how it works. Most of what neurons are doing is I/O signal carrying. The moving charges are what creates qualia and memory, and these probability waves inbound from the past always superpose with the present, to create your next thought.

EDIT:

* A Formula for Memory Strength of any past memory might be:

Integral of `f(t) * Mn` over entire causality chain, where `t` is zero at your birth and `t` is "now" for a memory.

f(t) = Mt / (Tt^2)

Where:

Mn = Magnitude of Qualia Now (current brain state)

Mt = Magnitude of Resonant Experience at time 't'

Tt = Short-hand for how many Foliations Ago time 't' was.

I think there is a mixture of useful insights and novice errors here. If you're interested, I can recommend Steven Byrnes' series on valence and self-models as some of the most compelling introductory blog essays about seriously approaching contemporary neuroscience through the lens of physics.

What I wrote in that post was just the simplest chain of thoughts to point people in the right direction, sort of as an exercise to see how terse I can make it and still cover the main points. That's not the full theory. Writing down everything I know would fill about 100 pages.
