ELI5: due to the massive amount of neurons in the brain, how is it possible that electrical signals don't crosspost (don't mind if I do) from one axon to another?

Electrical signals are transmitted in the most superficial outer layer of the axon (along the myelin sheath) or, at least, that's what I've been told at school.

Is this (if any, ofc) one of the reasons why human thinking is so complex?

They sort of do.

A neurone that transmits an electrical signal increase the chance that other neurones will fire.

And yeah, that’s another reason as to why we’re really complex.


An extra tidbit, neurones are not binary; 1 or 0. They are are more like **potentials**. So, when a neurone fires it does not mean that other neurones will fire, it only **increases the chance that other neurones fire.**

That’s probably why humans are so freaking diverse. Aa 0.004 difference in the time it took for a neurone to fire can make a **very big difference** in the result of an action.
