I don’t want to put you off anything, and I don’t know if this is helpful to you, but while quantum entanglement is probably a very real effect studied in quantum physics, any link to neural function (and even further from that to neurological disease) has to remain very very speculative at this point, because we simply don’t have the experimental tools to cover this stretch yet. Is it interesting speculation? Surely. Is it interesting to read up on? Probably. Would I base a (student) science project on this? Surely not.
It is too difficult for me to understand, but I liked the quote that Quantum.Fisher starts with, "“I can calculate the motion of heavenly bodies, but not the
madness of men” - Isaac Newton".
Also, this author states that there is just one possible molecule involved "m processing - a neural qubit - while the phosphate ion is the only possible qubit-transporter" and further down states that some measurements might be repeated. Sounds like the theory might easily be falsified.
If so, and it would take a physicist to convince me, I would pay taxes to help him or her falsify because I am a bit shocked that so much seems not well understood. I do not believe what I do not understand, but... I can imagine that someone would falsify whatever far fetched idea there is, and at low cost.
