What is EEG?

EEG is like a super-sensitive listening device that helps doctors hear what’s going on inside your brain.

Imagine you're taking a nap, and someone puts little stickers on your head, these are called electrodes. These stickers can feel the tiny electric signals your brain sends out when you think, dream, or even blink your eyes. It's like having a bunch of tiny microphones that catch every whisper from inside your skull.

The brain is full of neurons, which are like busy little workers sending messages to each other. When they talk, they make electric signals, and the electrodes on your head can pick those up. A computer then turns those signals into wavy lines, kind of like a brain’s heartbeat.

Doctors use EEG to see if your brain is working normally or if something might be causing you to have trouble sleeping, feel dizzy, or have seizures. It's like giving your brain a little check-up with a special listening device that can hear what it says.
