Where memories are stored All is dependent of memory. Memory is written to microtubules (MT), in the hinge of dimers. Two tryptophane, (their nonbonding electrons of indole group) from two dimer makes UNBOUND SINGLET (see Wiki). This happens ONLY when dynein walks against spin wave in MT, and they meet in same place. Dynein bend the hinge, like in magic angle of graphene and the unbound singlet "eat" that spin wave. Eating needs O2 and NO and their electron pair to make a bridge between two indole group. N2O2 broken the bridge and prevent memory writing. This happens in all Eucaryotes, also in plants, even they dont have septins. Spin waves born in many different methods. In axon they born from action potential and after saltatory conduction mowes back to action potential. If MT is streched longitudinal, the spin wave velocity slow down and the memories became comparable. Memory looks in MT like this: ....+......+........+.. It is spin wave function written in MT. If same sp
