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?

Question

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?

Answer 1

The distance between axons of different neurons is a lot bigger than the distance between individual jumps between the Ranvier nodes of the axon, the gaps in the myelin sheath. I doubt there could really be any kind of arcing across neurons given that.

Additionally, axons aren’t wires: they carry electrical charge, but not in the way that computer chips do, and so they can’t tally transmit across the space between axons.
