Electricity and Chemistry of the Brain

Your body is literally a biological battery running on salt. Inside your brain, billions of neurons

are playing a high-speed game of telephone right now. It starts when dendrites catch a vibe,

and if the signal is strong enough, boom, an action potential fires.

This is just sodium rushing in and potassium rushing out, creating an electric spike that shoots

down the axon. If your nerves are wrapped in myelin, that signal actually teleports by jumping

gaps to move faster. But once it hits the end, the electricity dies.

It has to swap to chemicals called neurotransmitters just to cross the synapse gap.

You are basically just electricity and chemistry in a trench coat.
