Microtubules are also just mechanically involved in synaptic firing. If you disrupt their chemistry you disrupt the ion transfer chains throughout the entire synapse. I’m not nearly read enough on the finer details on those mechanisms and definitely not the quantum theory you seem to be referencing to offer an expert opinion but I’m really inclined to go with Occam’s Razor on this one.

Who knows though, maybe you’re right, it certainly would explain some weird behaviors most microbiologists just kind of shrug off 🤷‍♂️
