Your brain is like a tiny city of energy, constantly buzzing with activity to keep you thinking, feeling, and moving. Though only the size of a cauliflower, it generates enough electricity to power a small light bulb.

How?
It’s all thanks to billions of neurons. These brain cells send fast electrical pulses—called action potentials—zipping through a vast network, sharing info about everything from emotions to motion.

Why the Buzz?
These electric signals power your thoughts, memories, and decisions. It’s your body’s control center, running on a sophisticated electrical grid.

Fun Fact:
If all your neurons fired at once, they’d produce about 20 watts—just enough to light up a bulb!
