How Does the Brain Keep Track of Time?

The brain uses tiny clocks inside it to keep track of time, just like a watch keeps track of minutes.

Imagine your brain is like a busy playground with lots of kids running around. Each kid has their own little timer that helps them know when it's time for recess or lunch. These timers are called biological clocks, and they work all day long to help you tell what time it is, whether it’s morning, afternoon, or night.

Inside your brain, there are special cells called neurons that fire like tiny lights blinking on and off. When these neurons blink in a pattern, they create something called rhythms, which help you tell how long things take, like counting seconds or knowing when it’s time to sleep.

Your brain also has a big clock that helps you know when it's morning or night. This is called the circadian rhythm. It works like a sun that rises and sets, telling your body when to be awake and when to rest, just like how you feel sleepy after playing all day!
