How smell unlocks memory | RMIT University?

Smell can bring back memories like opening a time capsule.

Imagine you're playing with your favorite toy, maybe a red ball that bounces really high. One day, you leave it outside, and it gets rained on. When you come back inside, you smell the rain and the earthy scent of wet grass. Suddenly, you remember that special moment when you were playing in the rain, laughing with your friends.

Smell is like a door to memory. It connects what we experience today with what we felt before.

When you smell something, tiny messages travel from your nose to your brain. Some of those messages go straight to a part of your brain that helps make and keep memories, the hippocampus. This means when you smell something familiar, like the scent of cookies baking or the smell of your mom's perfume, it can bring back memories as if they're happening right now.

It’s like having a special key for each memory, and sometimes, just one smell is enough to open that door, even if you haven’t thought about that moment in years!
