Stereotaxy

Okay kiddo, do you remember playing with a toy where you try to put a round peg in a round hole or a square peg in a square hole? That's kind of like what doctors do with stereotaxy.

They use a special machine to make a map of the brain or other parts of the body, and then they use it to help them put things in the right place. They might need to do this if someone has a tumor or other problem that needs to be fixed.

It's like a treasure map, but instead of looking for treasure, they're finding the right spot to put a tiny tool or medicine. And just like you need the right kind of peg to fit into the right hole, doctors need to make sure they're putting things in exactly the right spot so they can help people feel better.
