But does this help explain Representational drift?

From "Concept cells help your brain abstract information and build memories" https://news.ycombinator.com/item?id=42784396 :

> the regions of the brain that activate for a given cue vary over time

"Representational drift: Emerging theories for continual learning and experimental future directions" (2022) https://www.sciencedirect.com/science/article/pii/S095943882...

>> Future work should characterize drift across brain regions, cell types, and learning.

How do nanotubules in the brain affect representation drift?

There is EMF to cognition given that, for example, "Neuroscience study shows the brain emits light through the skull" (2025) https://news.ycombinator.com/item?id=44697995

Aren't there certainly quantum effects in the EMF wavefield of and around the brain?

The common understanding is that at the molecular scale that your nervous system operates, quantum effects are averaged out and don't lead to instability of neuronal activity.

Tegmark has used actual, you know, numbers and stuff to show that quantum effects in the brain are pretty implausible.

[westurner]

Again there, does the EMF/RF field created by the electrovolt wave function of the brain affect the electrovolt wave function of the brain? If so, isn't that a feed-forward feedback loop (where there may be quantum behavior)?

Does this paper also fail to assess other fields relevant to understanding nonlocal neuroactivation in disproving that there is any quantumness in cognition?

How do humans simulate digital and quantum circuits with the brain?

And, why do attempts to localize activations in the brain weeks apart fail; why is there representation drift?

What behavior precisely do you think is hiding in quantum region?

I'm on board with Hofstadter's strange loops but at most, quantum-level interaction should just amount to noise that is stabilized by the higher-order chemical region in which the brain operates. What even are we looking for at this point?

What aspect of my experience is not likely to just be a result of chemical interactions in the brain?
