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

In addition to myelin insulation, your brain also gets used to some neurons firing more commonly overtime than others, and in a way starts to make assumptions. One of the most common examples is during a heart attack. We don’t really feel our heart that often, so when it does start sending signals to the brain, it often feels like a left arm or shoulder, and maybe some jaw and neck pain. Because those are parts that commonly send info to your brain, your brain assumes that’s how the info should be interpreted.
