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 action potential of the neuron has to be sufficient to get the neurotransmitters to dump. When they do, it’s only in the synaptic cleft designated by that one axon for the next. Or so I recall. But damn it’s been a whole minute since college.
