Chapter 8

The difference between a whisper and a scream is just how fast your brain cells are firing.

Your neurons are like tiny, charged batteries, always waiting for a signal.

When you experience something, like tasting your favorite food, it triggers a small

electrical blip. If that blip is strong enough, it crosses a threshold and unleashes a

massive electrical spike called an action potential. This zap is the universal language

of your brain. But here's the wild part: a stronger feeling, like intense pain

or loud music, isn't a bigger zap. It's just your neurons firing the same zap over and over,

faster.
